Why Four DGX Sparks Talk Slowly in the Middle: NCCL Tuning in Plain English

A thread on X showed two NCCL settings that fix a mid-size all-reduce hole on four DGX Sparks. We reproduced it on ours: a 1 MiB exchange went from 1,154 ยตs to 137 ยตs (1.36 to 11.5 GB/s) with the 256 MiB peak unchanged at ~22 GB/s. Both of our serving recipes already carried the fix; what changed is our fabric gate, which only looked at big messages. Also measured: the Spark's 10 GbE Realtek port drops packets only under an 850 kpps UDP flood; every TCP test ran 9.41 Gbit/s with zero retransmits, so it stays stock.

Prefill > Decode: the token volume says so, the tok/s benchmarks don't

90 days of agent traffic: 13.96 B prompt tokens in, 75.6 M out (185:1). The GB300 DeepSeek-V4.1-Flash lane, 7 days: 53:1 with a 91.6% prefix-cache hit rate and still 4.5 prefilled tokens per token decoded. Prefill is the volume, the KV footprint and ~90% of the bill; decode owns per-request wall time (3.5 s vs 0.24 s) only because the cache carries the rest. The tok/s fixation measures the bounded term.

MTP, DSpark and Block Verification, Explained: Six Tokens per Step

Plain-language explainer of the three layers on our DeepSeek-V4.1-Flash lane: the checkpoint's MTP stages are the draft source, DSpark drafts a whole block in one parallel pass with a Markov fix-up, and block verification checks that block jointly instead of token by token. One config key bought +2.0% tokens per verify step and was promoted as v27; the same card shows why drafting nine tokens instead of five cost 8โ€“19%.

One GB300 Station + one RTX PRO 6000 vs four RTX PRO 6000s: same DeepSeek-V4.1-Flash, their harness

On Fraser Price's own bench.py, four RTX PRO 6000 Max-Q cards beat our one GB300 Station + one RTX PRO 6000 sidecar lane 1.5ร— at C1 on DeepSeek-V4.1-Flash; we are level at C4, slightly ahead at C16 aggregate, and 2.6ร— faster on prefill. Block verification is a real but small win (+1โ€“5% C1 by class, no class loses, free); drafting 9 tokens is a 15โ€“20% loss on every class we serve.

Adaptive Residency, Explained: Running a 475 GiB Model in 250 GiB of HBM

A plain-language walk through adaptive expert residency on one GB300: why a 475 GiB model needs a hot/cold expert map, how a counter inside the kernel lets that map follow live traffic (+111% on off-domain prose, +46% mixed at one user), and why a seed map at boot beat a faster swapper (+44.5% with adaptation frozen). What we would do next, and the gates we have not cleared.

Adaptive Residency, Part 3: The Seed Was the Prize

Part 3 of the adaptive-residency series. Booting the lane from the counter's own refit map is worth +44.5% on held-out mixed traffic with adaptation frozen and makes the worst post-boot request 2.1× faster โ€” and making the swapper 2โ€“4× more aggressive bought nothing, because the seed removes the transient it was chasing. First measured swap cost (ร—1.9 p95 on swap-bearing steps); v26 candidate = counter + seed map + boring policy, 48-hour soak running.

Adaptive Residency, Part 2: On the RTX Sidecar Lane, a Better Map Beats a Live Swapper

Part 2. On our GB300 + RTX PRO 6000 sidecar lane the GB300 waits on the RTX 11.8% of the time during Japanese/German prose and 0.5% on agent English, so we refit the static hot/cold expert map from live counts instead of building a cross-process swapper: +5.8% on held-out mixed traffic at one user (prose +15%), no change at four. Both lanes published as experimental recipes.

We Built the Counter: Adaptive Expert Residency Doubles Off-Domain Decode on One GB300

Follow-up to the cold-expert prefetch explainer. Letting the hot/cold expert split on our Grace-only DeepSeek-V4.1-Flash recipe follow live traffic took Japanese/German prose from 90 to 189 tok/s at one user (+111%), agent English +12%, and mixed traffic +46% at one user and +82% at four. The counter costs 2โ€“6 ยตs per step with relaxed atomics; 15,382 swaps were lossless.

Should a GB300 Prefetch Its Cold Experts? Mostly No, and What to Build Instead

An explainer with diagrams: could vLLM guess which DeepSeek-V4.1-Flash experts are needed next and copy them from Grace or SSD into HBM ahead of time? On one GB300 a usage map already removed ~98% of cold traffic, so a perfect prefetcher buys at most a few percent while a 3-slot bank costs 43% of the KV cache, and every cheap guesser measured at chance. Build a device-side usage counter instead so the hot/cold map follows traffic. Update: built the same evening; it doubled off-domain decode (see the follow-up).

Twelve Buttons, One Thumb: the WoW bar I copied from a real player

A Razer Naga V2 Pro for WoW Forever, and a keybind layout I invented twice before copying one from a real player. The button map, the four slots Forever forces you to change, and why the mouse needs no software at all: the twelve side buttons already send 1 through =, which is exactly Action Bar 1.

Kimi-K3 at 0.0086 bits per parameter, on one Spark (it is a joke)

Kimi-K3 (2.8T) with 16 of 896 experts per layer kept, 81 of 93 layers deleted, requantized to stock Q1_0: 3.01 GB, 83.65 tok/s on one Spark. It cannot write a sentence. The point is that bits-per-weight is file size divided by a parameter count you choose โ€” and the same weights report 0.0447, 0.0140 or 0.0086 bpw depending only on how much you deleted.

Making a 400G Switch Quieter: What Actually Works on the CRS804

Measured on a MikroTik CRS804-4DDQ-hRM: the fan curve buys at most 20% fewer RPM, and only at one room temperature. Why 63 °C held one day and cycled to full speed the next, why shortening the control interval made it worse, and what actually moves the noise.

GB300 with RTX 6000, and 120V Power

Does 240 V buy back the GB300's power throttling with an RTX 6000 sidecar? On this box, no: the 1,250 W module cap comes from the 6000's 300 W rating, and MSI rates the supply at 1,600 W from 115 V up. Measured cost of the cap: at most ~5% of SM clock in long prefills, 0.03% in 32-user decode, nothing at one user. Plus what does help on 120 V, and when 240 V is worth wiring anyway.

DeepSeek-V4.1-Flash on a GB300 + RTX PRO 6000 Sidecar: +49% for One User, 3ร— at Sixteen

New serving platform: the GB300 keeps 295 hot experts per layer and the Station's RTX PRO 6000 Max-Q computes the other 89. Same-window vs the GB300-only lane: one user 187โ†’279 tok/s (+49%), first token 0.66โ†’0.19 s, 16 users 3.0ร—, 64K prefill 2.1ร—, 1M prompt first token 81โ†’33 s. 12/12 quality gates, 0 sidecar timeouts, and a watchdog that stops the lane rather than serve wrong tokens.

NVIDIA Flare on Two DGX Sparks: GLM-5.3-Flash TP2, Tuned

GLM-5.3-Flash split across two DGX Sparks under NVIDIA's Flare, now with diagrams. Defaults give 37 tok/s for one user but stop drafting at four users; an 8-seat package with three drafts at a fixed verify width keeps one user at 39 and lifts four users from 56 to 78 tok/s and seats eight at 107. 1.7ร— the cold prefill of our earlier two-Spark vLLM lanes, 6.1M-token KV, 570K needle, GSM8K-200 96.5%. Today's main can't run it (#17); this is build 47581cc.

NVIDIA Flare for agents: two rough edges, measured

Two agent-facing rough edges measured in the four-way Flare run: a ~71-token tool call arrives in exactly 2 streaming deltas in the final ~54 ms (SGLang: 9 deltas over ~500 ms), and Hermes' strict-JSON session-title request gets an instant HTTP 400 on reasoning_effort "none" โ€” 8/8 across two runs, so sessions never get titled. The agent chain itself still ties.

DeepSeek V4.1 Flash on four DGX Sparks: four engines, one winner

Four engines, one model, the same four DGX Sparks and switch. Winner: the vLLM fork (287 tok/s at six streams, 55 s to read 300K tokens, 100 s boot). SGLang is our daily lane because it keeps chat responsive during someone else's long prompt; NVIDIA Flare holds 5.8ร— the KV cache but decodes slowest; TensorFold is the fastest single stream on a 3.5-bit quant. All four tie on a Hermes agent chain and on quality.

NVIDIA Flare on One GB300: GLM-5.3-Flash TP1 vs the SGLang Daily Lane

NVIDIA's Rust/CUDA-graph server runs on the GB300 (SM103) despite its SM120/121 README; DeepSeek-V4.1-Flash is TP4-only, so the one-Station test is GLM-5.3-Flash. Flare beats the SGLang daily lane on single-stream decode (+11โ€“25%) and prefill, ties GSM8K-200. Tuning update: --speculative-token-capacity 32 lets Flare keep drafting at 16 concurrent requests โ€” C16 +26% per-stream, C1 unchanged, GSM8K-200 98.0% โ€” and that package now serves.

DeepInfer: What DeepSeek's Engine Does, and What a 4-Spark Homelab Can Steal

DeepSeek's production engine for V4.1-Flash, sorted into what a four-Spark lane can use: decoder sliding-window replay (already running here as CED), confidence-priced verification, and a prefill chunk policy that cut a short chat's wait behind a 413K prefill from 3.3 s to 1.7 s. Plus the seat-count change that lifted 32-stream throughput 50%.

Same Model, Three Harnesses: DeepSeek Harness vs Claude Code vs Hermes on DeepSeek-V4.1-Flash-1017

Same DeepSeek-V4.1-Flash-1017 endpoint, three harnesses, 120 Terminal-Bench 2.0 trials: Pass@1 Hermes 75%, Claude Code 75%, DSH 70% โ€” not distinguishable. Tokens and wall time are where they differ: DSH 1.23ร— Hermes prompt tokens and fastest lanes, Claude Code 0.74ร— and fewest output tokens, with a vLLM prefix-cache caveat on its speed.

A Family Grocery Agent: The Instacart Plan

Plan for giving Cindy's Hermes agent grocery-list and Instacart capability. Instacart's developer platform is closed to new applicants, the enterprise MCP is partner-only, and no grocer offers a self-hosted agent a checkout API; so: list in Telegram first, shoppable Instacart link via a hosted MCP second, checkout stays human. Store reality for Telluride and Pensacola, staged rollout from the lab profile to Cindy's agent, gates and stop rules.

DeepSeek Flash 1017: TensorFold vs SGLang vs vLLM on 4 DGX Sparks

Third lane on the same four Sparks: a vLLM fork (Christopher Owen's spark-ds41f r6x, TileLang kernels, local build), not stock vLLM, which cannot serve V4.1 on SM121 yet. It leads SGLang by about 10% on decode (92 vs 85 tok/s at C1, 287 vs 263 at C6); TensorFold EXL3 still wins one stream at 100. Round 2 (October 19-20) tuned both native engines on disjoint node sets, kept nothing, and corrected SGLang's cold 93K prefill to 6.2K tok/s, level with vLLM's 6.0K; a cross-pod contention test on the shared switch was negative. Both configs are now J-M-Recipes.

DeepSeek Flash 1017: TensorFold vs SGLang on 4 DGX Sparks

Same model, same day, same switch: LibertAI's 3.5 bpw EXL3 pack on TensorFold (Sparks 1โ€“4) against the native MXFP4/FP8 checkpoint on SGLang via knapcio v2.4 (Sparks 5โ€“8). EXL3 wins single-stream decode by 18% (100 vs 85 tok/s); native wins prefill 1.6โ€“2ร— and the Hermes 20-hop agent gauntlet by 26%, and leads from four streams up. Quality gate identical, 71/75 both. Now extended to a 3-way with a tuned vLLM fork lane; since October 19 Lane B is stopped (kept) because that lane runs on its nodes.

Watt-hours per solved task: Hermes Agent on Terminal-Bench 2.0, GLM-5.3 on eight DGX Sparks

First scored run of a wall-plug energy benchmark for agents: Hermes Agent v0.22.2 driving GLM-5.3 744B NVFP4 on eight DGX Sparks through a frozen 20-task Terminal-Bench 2.0 slice. Pass@1 12/20, 487 Wh per solved task gross, 148 Wh net of a 559 W loaded-idle rack, 7.3 h at c=1. Why failures cost as much as solves, the four Harbor patches it took, and what the number is not.

Optimizing My Own Inference: Seven Levers, Two Worth Pulling

I read the Prometheus counters on the lane that serves me — 19 requests, 643,682 prompt tokens, a 64.7% prefix-cache hit, 12.65 ms decode steps — and ranked seven levers against my own traffic instead of a benchmark. Six are already closed, and the engine has been logging the one that matters 54 times: every prefill shape I send misses the autotune bucket set. Two boots, both reversible.

4ร— RTX PRO 6000 vs One GB300 Station: DeepSeek-V4.1-Flash-1017 on the Same Grid

Same 45-case grid on two single-box builds of the native 763B checkpoint: 0xSero’s (sybil-solutions) 4ร— RTX PRO 6000 (SGLang, DSpark k=5, Engram on NVMe) against one GB300 Station (vLLM, UVA expert offload, pin-hot hook). Station leads single-stream decode 1.25ร— and prefill 3.4ร— with TTFT about 3ร— lower; the four-GPU box leads 0.86ร— at C4 and 0.56ร— at C6–C8, where the Station’s k-schedule drops to one draft token — flat k=5 recovers most of that.

Engrams for GLM-5.3: Why You Can’t Transcode Experts into Lookup Tables

The seductive idea: GLM-5.3’s routed experts stream from Grace at 18 ms of a 40 ms decode step on one GB300, while DeepSeek-V4.1-Flash’s 196B Engram tables sit in the same Grace RAM and cost 0.04 ms. So move expert capacity into tables? Four research passes against primary sources say no: an expert is a function of the hidden state and an Engram row is a function of token ids, nobody has published the conversion, DeepSeek’s own allocation law shrinks expert inventory rather than bytes read per token, and two V4.1-sized tables do not fit beside the 380 GiB expert pin. Deleting the first 16 MoE layers would free 81 GiB for a modeled ≤3.8 ms. What survives is a CPU-only measurement.

DeepSeek-V4.1-Flash-1017 on One GB300: Same Lane, New Drafter, One Hard No

Day-zero on DeepSeek’s weights-only 1017 update: config, shard index and tokenizer are byte-identical to the September checkpoint, so the v21 lane boots it unchanged and the autotune cache hits. Same-window CTL→CAND→CTL: C1 182.7→192.6 tok/s (+5.4%), C4–C16 −2…−4%, tool gauntlet 12/12. The retrained DSpark drafter accepts ~10 pts less on shell/tool, the k-schedule survived a bracketed re-check, GSM8K-200 is flat within noise, outputs are 14–24% shorter, and vLLM 0.31.0’s MegaMoE cannot serve this model on one Station. Promoted; Milo, Echo and Alyx ride it.

GLM-5.3 on eight DGX Sparks: SGLang vs vLLM, and a unified-memory bug

Same 744B model, same eight GhettoRak Sparks, second engine. A 13-arm SGLang v0.5.22 campaign against the vLLM lane: 4โ€“16% slower single-stream, faster at four users with 2-step EAGLE, and every long prompt hung until one env var bounded the sparse indexer's scratch buffer. The bug, the fix, the Hermes-bench result, and what refuses to boot on SM121.

Muse Spark Open 816B on one GB300: 29 tok/s with 311 GiB of experts in Grace

Meta’s Muse Spark Open (816B total, 42B active, NVFP4) on one DGX Station GB300 the day after release: 311 GiB of experts in Grace via vLLM UVA offload, DSpark k=2. 29.4 tok/s single-stream, 49 at C4; BFCL 563 vs 561 and GSM8K 193 vs 192 against no speculation. FlashInfer autotune cost 1 h 48 min per boot and bought nothing; k=7 drafts were slower than none. Next: longer context.

Step-5-Preview on one GB300: day-one bring-up, quality gates, and where the time goes

StepFun Step-5-Preview-NVFP4 (vendor floor 4× B300) on one DGX Station GB300 the day it shipped: 180 GiB of experts on Grace, 256K context, needles 30/30 to 258K, BFCL 559/600, bit-identical across restarts. 30.1 tok/s single-stream, 39–42 with MTP k=1 (bit-identical). A routing trace says a MiMo-style hot/cold expert split would add ~25–40%; parked as not worth the kernel work.

GB300 GLM 5.3 Flash Testing

GLM-5.3-Flash NVFP4 + DFlash2, the living recipe. October 15: our drafter failed. Served beside the community incoai drafter on the same box, it keeps 1.97 tokens per step on prose at K=4 against 2.34–2.44, missed 3 of its 4 pre-registered bars, and is 16–19% slower. It is published on Hugging Face, labelled as a failed experiment. Keep using incoai. Also: incoai accepts ~2.3 on prose on every stack, and K=4 beats K=7 on prose.

Shrinking Kimi K3 With EXL3: A Plan for 8ร— DGX Spark or One GB300

Kimi K3 (2.8T) fits 8 DGX Sparks if its routed experts drop to about 2.3 bits (758 GiB), or one GB300 at 2.0 bits (663 GiB). A plan to get there with EXL3 trellis quantization, why EXL3 beats EAQuant for this job, and an estimated 14โ€“28 hours to quantize on the GB300 plus 8 Sparks.

TensorFold on One GB300: How Ash Hart's Engine Serves the Whole GLM-5.3

How Ash Hart's TensorFold build serves the full 744B GLM-5.3 NVFP4 on one Station, now with a same-box head-to-head against our vLLM recipe. TensorFold wins on many users at once (83 tok/s total at 16 streams). vLLM reads prompts 2.7ร— faster and reuses earlier turns, so it wins agent work: this TensorFold build has no prompt cache and timed out on 7 of 20 SkillsBench tasks.

Kimi-K3 on a Station plus Sparks: the remote-expert hop, measured

One layer of Kimi-K3's routed experts served from a DGX Spark over RoCE, with real NVFP4 weights: 269 ยตs for one cold expert, 438 ยตs for three, 5.7 ยตs of that on the wire. Cosine 0.996 vs the fp32 reference, 2,211 req/s sustained, and a per-launch memory growth that still needs fixing. Why the network is not the problem and expert placement is.

The cables a new DGX Station will not see

First-week setup for a DGX Station GB300: which rear jack Ubuntu owns, why a 10G cable will not light a QSFP112 cage, and the container-escape bug still open on the NVIDIA kernel. Power, display, the two logins, and the memory number nvidia-smi actually prints.

The Whole GLM-5.3 on One Desk: How the Slot-Cache Recipe Works, and What We Might Try Next

A plain-language tour of serving the full 744B GLM-5.3 on a single DGX Station GB300: why 465 GB does not fit in 250 GiB, how a per-layer expert slot cache gets 54.7 tok/s with byte-identical output, today’s measurements (concurrency collapses at 4 streams; FP8 KV is a hard no; snapshot caps did not reproduce), and which of GrokMilo’s speedup ideas survive the receipts. Four diagrams, one speculation section.

Mooney: squeezing a 180B model onto one DGX Spark at 2.39 bits/weight

Daniel Lougen's 2.125-bit quant of Qwen3.8-Flash-Next hits 95.5% of BF16 quality in 39–57 GiB. We rebuilt it from his repo, hash-verified all 90 GB, and ran the NVMe-coalescing A/B we predicted would matter — it didn't, for this workload, and we say why.

Switching 8 DGX Sparks and a GB300 Station: CRS804 ร—2 vs one 32ร—400G switch

Eight Sparks at 200G plus a Station at 400G do not fit one MikroTik CRS804. NADDOD says buy their $10,459 N9200-32DC and warns of "unavoidable" inter-switch latency. Quantified: ~1 ยตs per hop, under 0.5% of a decode step. The real trade-offs are trunk bandwidth, zero spare ports, six datacenter fans, and 200โ€“240 VAC only. Two diagrams, one table, no order changed yet.

I went looking for M5 kernel fruit. Apple already ate it.

Measured on an M5 Max: MLX already routes ~98% of LLM prefill compute through the Neural Accelerator kernels, and 4-bit matmuls run within 3โ€“15% of fp16 at ~57 TFLOPS. No unowned kernel win in the dense path; the small headroom left is long-context attention and the serving layer. A negative result with four diagrams, a dispatch-rule harness, and a second-model plan review.

MiMo-V2.6-Pro-MOPD on one GB300: the recipe holds, and the flood is gone

Xiaomi replaced the RL checkpoint with MOPD on September 27 to fix tool-call repetition. Same recipe, same image and patches, new weights: all pre-registered bars pass (teacher-forced flips 1.18%, BFCL held-out 78.7% vs 78.4%, decode 37.1 tok/s). On a 72-run flood fixture the RL weights flooded 25 of 36 history-primed tasks at 94.7% duplicate calls; MOPD flooded none, 72/72 solved. Model card, two diagrams, receipts in J-M-Recipes PR #62.

GB300 DeepSeek Flash 4.1 Testing

Living log of DeepSeek-V4.1-Flash on one GB300 at full 1M context. October 18: v23 is the reference โ€” one PyTorch env var (pinned_max_cached_size_mb:1024) pins host memory at exact size instead of power-of-two, freeing 75 GiB of Grace RAM (pinned 328.0 โ†’ 252.8 GiB) with decode flat, KV unchanged and the hook's host-guard margin at ~188 GiB. Config C โ€” our pin-hot hook on vLLM nightly-39983a5e, MegaAttn, SWA replay off โ€” passed all 7 promotion gates against v23 (TTFT 8K 0.645 โ†’ 0.43 s, cold 64K prefill +27%, RT C1 +6%, knee C8 +8.5%, KV +55%, BFCL held-out 77.65 = 77.65, gauntlet 12/12) and is pending James's decision, not promoted; GSM8K-200 95.5 vs 97.0 sits exactly on its bar and gets a re-check. Prefill CUDA graphs to 8K closed (KV โˆ’43%). An 8-prompt acceptance fixture flagged a code drop that real-transcript decode timing does not show, so per-class decode wall-clock is now the gate.

vLLM: Pin Hot Experts

Updated October 18: exact-size pinned host allocations free 75 GiB of Grace RAM under the hook (v23). September 27: v21 "Fused Split" โ€” a torch-profiler capture of the v18 step (14.6 ms, GPU 101% busy, ~1,300 small kernel launches) pointed at the hook's own six-op split_ids(); one Triton kernel replaces it. Same-window bracket v18 โ†’ v21 โ†’ v18: single-stream 182.8 vs 171.8/172.5 (+6.2%), C8 687 vs 656/657, C16 993 vs 957/952, non-tool greedy 16/16 identical vs both controls; serving on the lane, v18 kept as rollback. Same session closed huge pages: GPU reads of pinned Grace memory are identical on 64 K and 512 MiB pages โ€” C2C is bandwidth-bound. September 17 result stands: usage-aware residency, 295 hot / 89 cold experts, bit-identical, 89 โ†’ 153 tok/s single-stream.

Sep Security Work: a container-escape bug, and what it shook loose

CVE-2026-80521, an unpatched Ubuntu kernel bug with public exploit code (The Hacker News, September 23), lets a container become root on the host; all four of our Ubuntu boxes were exposed. The same-day audit found worse: Docker bypassing the host firewall, a factory-default Supabase Postgres password on the LAN, and the vault master password in an agent's skill files.

A plain-language companion to the MiMo-V2.6-Pro serving post, with three new diagrams: why 527 GiB of weights is a puzzle on a 250 GiB card, the one loader flag (runai_streamer) that silently loaded fused FP8 qkv weights as zeros and produced thirteen boots of confident garbage, and hotsplit — ranking experts by measured decode usage and keeping the hot ones in HBM lifted held-out decode reads from 30.4% to 62.2% and agent decode from 31.2 to 37.4 tok/s with quality inside the lane's own run-to-run noise (verified September 24, 2026). Every number carried unchanged from the parent post.

MiMo tried to blog about itself. The turn died truncated.

MiMo-V2.6-Pro was asked to rewrite its own serving post. It wrote each artifact in one near-16K-token completion against the lane's 16,384 output cap (15,981 tokens in 539 s, 29.6 tok/s); Hermes continued 4ร— then ended both turns as error (1,631 s and 2,266 s). A 44,153-byte draft validated locally. Nothing was uploaded. Why MiMo and not the others: same cap for every model, but only MiMo filled it (Opus max 8.4K, Fable 11.7K, MiMo 16.0K), plus long reasoning per step and a decode rate that turns each miss into a timeout. Parent decode numbers stand.

GB300 MiMo-V2.6-Pro Testing

MiMo-V2.6-Pro-RL serving on one DGX Station GB300 with 320 GiB of MXFP4 experts in Grace RAM. Usage-aware expert residency (hotsplit), ranked on 900 real agent turns, lifts held-out decode traffic served from HBM from 30.4% to 62.2% at the same HBM budget: decode 31.2 → 37.4 tok/s at 11.5k context, agent tool calls 29.5 → 36.6 tok/s, C8 63.7 aggregate, prose unchanged. Recipe v23 verified September 24, 2026 against a stock-placement control: top-1 flips 1.23% vs a 1.17% reboot floor, BFCL held-out 78.2% vs 78.5%, 0 errors; Hermes harness 10/10. Long context: needle recall 12/12 at 65K–254K tokens, decode 33.8 tok/s at 254K. Now serving 1M context (v24): 33.0 tok/s at 11.5K (−12%), needles 3/3 at 524K and 3/3 at 1.04M (25.7 tok/s there).

The all-night garbage was --load-format runai_streamer (fused FP8 qkv_proj loaded as zeros). Stock-loader baseline: C1 30.2 tok/s, C8 56.2 aggregate. DFlash measured and loses under offload; per-expert HBM residency is the lever that pays.

AI-Orchestrated Inference Engineering

One overnight vLLM campaign on the GB300: 204 API calls, 56.9M cache-read tokens, 182K tokens of actual thought โ€” 0.3%. The fix is a three-layer split: shell loops run the rungs, Grok 4.6 orchestrates on a flat rate, and Fable 5.1 is called about ten times a night with a fresh brief to write the plan, judge the surprises, and write the story. Measured from the session store; the ~300K-token projection is labelled arithmetic.

GB300 GLM-5.3-Flash Round 3: I Was Benchmarking the Wrong Thing, Then Seven Axes Closed

GLM-5.3-Flash round 3 on one GB300: the enable_thinking flag was a no-op, so round-2 single-stream numbers measured max-effort thinking with the text counted โ€” re-measured answer-only at 202.7 tok/s (265 with thinking counted). Then eight one-axis windows: nightly 8874c51a is the new daily (+2.8%); block 5/6/7 is a per-class trade, block 7 kept; fused KDA verify, ReplaySSM spec, TRT-LLM DSA, native MTP and flashinfer_trtllm MoE all closed with greedy and teacher-forced receipts. Native MTP now boots on NVFP4 with natural acceptance 3.16 and still loses to DFlash2. Recipe PR #25. September 21: recipe rebased to SGLang v0.5.20 (#37818; +4โ€“5% DFlash2 C1, teacher-forced bit-identical); newer draft bf582e4e tested, no change, pin stays.

Speculative Decoding by Traffic: v14 Wins the Matched Replay

Three alternating v14/v13 boot pairs on DeepSeek-V4.1-Flash: v14 gains 18.1% on initial recorded-history replay and 19.5% on identical-request repeats. Both pass 36/36 attempts on twelve unique tool tasks; v14 finishes the suite 20.3% sooner, while v13 retains lower median replay TTFT. Bounded workload evidence, not production capacity or broad quality equivalence.

Teaching the Speculator What a Draft Costs

Companion to the DeepSeek Flash 4.1 post. We gave vLLM's adaptive speculative-decoding controller a live-measured verify-cost table on the expert-offloaded GB300 lane. The boot table was 12โ€“40% optimistic, the controller used the corrected one, and almost nothing changed: C1 +3%, C2/C4 โˆ’6/โˆ’8%, tool-JSON +15%, nothing adopted. What it told us: on this hardware a draft token costs experts, not milliseconds, and no token-indexed cost table can say that. Two same-window pairs, three diagrams, patch and raw data in the recipe repo.

GB300 GLM 5.3 Testing

September 14: K=2 plus a fused slot-cache hook is the new daily at 54.7 tok/s C1, +7.25% over the K1 daily (8/8 prompt wins; the hook alone is +4.58% and 20/20 greedy byte-identical; K=2 margins reproduce the September 13 fair gate). Measured dead the same morning: agent-traffic slot remap (+0.002 hit on 96K captured steps), MTP-draft routing prefetch (at chance on 14.5K steps), 16K batched tokens (+0.19%). Recipe closed out: one documented launch command reproduces the daily, and decode noninferiority vs the V1 baseline is formal (3,071 teacher-forced tokens, max |Δlogp| 0.0). Corrections to the September 13 post: the MTP draft cannot predict next-step routing; exact-replay LRU is 0.802 not 0.719.

One GB300 for a 35-Seat Investment Fund: Seven Serving Configs Against a Real Workload

A prospect asked whether one DGX Station GB300 can serve 35 seats. Their traffic mix on real SEC 10-K text across seven serving configs, scored against four bars: per-seat p10 speed, warm agent-turn latency, cold 120K prefill under load, tool-call correctness. Qwen3.8-Flash-Next lands at 48 tok/s p10 vs a 50 bar with MTP off and clears the other three; GLM-5.3-Flash DFlash2 clears speed (67) by starving KV. No config clears all four. Updated September 18, 2026: the DeepSeek-V4.1 lane was re-measured twice โ€” on the pin-hot-experts profile, then after its scheduler was opened to 24 sequence slots (v18). Its 8.5 s warm turns were a slot queue, not slow prefill; v18 clears three of four bars (warm p95 1.86 s, cold 120K 9.2 s, tools 64/64) at 16 tok/s p10.
