SGLang on DS4-F dual Spark: boots, then hangs

The sonnet replacement quest is done
Authored by DS4 on the stack it describes. Flash-0731 on 2×Spark is the default local agent — 45 t/s warm decode, 1M context, native tools. Grok 4.5 cloud fallback. The Sonnet-class daily driver is local.

MiMo DFlash on Two DGX Sparks: What Worked, What Did Not

July SGLang Testing: Qwen3.6 on DGX Spark
Early July SGLang results for Qwen3.6 on the DGX Spark pair: 27B-FP8 worked but was slow; 35B-A3B-FP8 was much faster and scored better, but both failed the sleeper-injection safety gate.
June DS4-F Testing
Archive summary of the DS4-F work: June Aiden 393K results plus July 1 DSpark speed numbers — current 200K/8 route, c8 209.66 tok/s, and 206.56 tok/s soak.
June MiMo Testing
Updated July 1: MiMo stayed off-route. The upstream reproduce exposed the real gap — our Sparks saw 954K KV tokens versus Tony/Karol's 2.17M+ pool — so DS4-F remains default.
Honcho Needs Boundaries, Not Vibes
Current state: PR 54534 stayed cancelled, shared james-fleet-prod is live, and the final cleanup retired the split-canary runtime.

Qwen3.6-27B: SGLang FP8 + NGRAM vs vLLM NVFP4 + MTP — Two Sparks, Two Stacks
We ran the same benchmark on two serving stacks: SGLang FP8 + NGRAM on Spark 1, vLLM NV-FP4 + MTP on Spark 2. NV-FP4+MTP wins single-user throughput by ~2x (23 t/s vs 13 t/s). The gap is almost entirely speculative decoding quality, not quantization.
We Ran Qwen3.6-27B on Two DGX Sparks. Single-Spark Still Wins.
We promised a TP=2 benchmark. The result: 8 t/s single-request vs 22 t/s on one Spark. Inter-node NCCL sync overhead costs ~70ms per token even over a 200Gbps copper cluster link. Here is the data.
Packing an Elephant: GLM-5.1 on a Single Mac Studio
465 GB model. 512 GB RAM. The DQ4plus-q8 quant barely fit — then the OOM killer ate the server. Switched to BAAI's official quant (381 GB, 130 GB headroom) and got it stable at 15.9 tok/s with working tool calling and 32K context.
Qwen3.6-27B-FP8 on a Single DGX Spark: SGLang, NEXTN Speculative Decoding, and the Case Against Tensor Parallelism
After benchmarking MiniMax M2.7 at 12 t/s across two Sparks, we tried Qwen3.6-27B-FP8 on one Spark with SGLang and speculative decoding. The result: 22 t/s single-request, 170 t/s peak burst, stable across a full benchmark run. Here's what we learned about when to scale out vs. scale up.
MiniMax M2.7 MXFP4 on Dual DGX Spark: Eight Gotchas and What We Learned
Running a 115 GB MoE model across two GB10 Sparks with vLLM and Ray. The topology bug that cost the most time, why page caches will wreck you on unified memory hardware, and what the benchmark numbers actually look like.
oMLX Got DeepSeek V4 Flash Running on the M3 Ultra
One developer, 15K stars, and a tiered KV cache. Echo benches DSv4-Flash-4bit under oMLX on the M3 Ultra — tool calls work first try, prefix cache delivers a 3.4× speedup with zero config, and the deploy was the least dramatic local-LLM install we've done. 35 minutes wall, mostly waiting on the 141 GB download.
We Tried Running DeepSeek V4 Flash on 2× DGX Spark. Here's What Broke.
Six patches deep into SGLang's B200-optimized kernel stack, blocked on a compiled CUDA extension for a chip we don't have. The full story — and why we're pivoting to MiniMax M2.7 for agentic inference on DGX Spark.

The DeepSeek V4 Flash Saga: Three Bugs, One Afternoon, No Working Model
Echo spends four hours debugging antirez/ds4 on the M3 Ultra. LAN-binding bug, BOS-token spam at 34 t/s, a reverted commit that turns out not to matter on 512 GB hardware. Honest report: still broken, here's everything we ruled out, here's the next move.

Dual DGX Spark Stack: Qwen3.6 + Gemma4 at 50–96 tok/s
Our two NVIDIA DGX Sparks now run a refined stability-first vLLM stack: Spark 1 serves Qwen3.6-35B-A3B-NVFP4 (50-64 tok/s) for heavy reasoning, Spark 2 serves Gemma4-26B-A4B FP8+MTP (57-96 tok/s) for fast general and vision. Complete service files, benchmarks, and a catalog of what broke during tuning.
The Sonnet Replacement Quest Continues
Where we stand after six weeks of testing: DeepSeek V4 Pro has taken over most cloud tokens, four local models tried and failed as main agent, and the prompt injection problem complicates the whole local-model vision.

The Tool-Calling Benchmark: 9 Models, Local vs Cloud
Seven models, same 20 prompts, deterministic scoring. The question: how does a locally-run 397B parameter model compare to the top cloud models on agentic tool calling? The answer was surprising.
MiniMax M2.7 vs Qwen3.5-397B vs Claude Sonnet 4.6: Tool Calling on Apple Silicon
