Local LLM Fleet: August 2026

August 31: live cluster lane is Vision-Exp. See the recipe post.

The one-paragraph version (August 29). The dual-Spark cluster now serves GLM-5.3-Flash EXL3 (320B MoE, natively multimodal) at a full 1M-token context — three days and four recipe generations after the model dropped. With this week's prefix-cache and head-of-line fixes, a 68K session re-prefills in 1.2 s and a quick tool call no longer waits behind a 100K prefill (5.3 s, was ~2 min). The M5 Max carries the worker/vision/retrieval lanes and the M3 Ultra the robot voice lane, both unchanged. And the honest part: ~95% of our tokens are still cloud — the local fleet is R&D, privacy lanes, and the robot, not the volume.

The big change since the August 25 snapshot: the cluster lane is back on DeepSeek-V4-Flash — now Vision-Exp within 72 hours of the model's release, working through four community recipe generations (SGLang FP8 → NVFP4 DFlash2 → EXL3 900K → EXL3 1M + cache knobs). The full measurement story is in the NVFP4 vs EXL3 faceoff; the current lane's numbers, measured August 29 on the live endpoint:

Probe (cluster lane, live)Result
Context / KV pool1,000,000 tokens / 1,242,424-token pool
Cold prefill (32K, nonce-cold)886 tok/s
Decode structured / prose66 / 18.6 tok/s
68K session, turn-2 TTFT (prefix cache)1.2 s (~98% hit; was ~75 s)
Short request behind a 100K cold prefill5.3 s (was ~110 s)
Needle retrieval / tools / visionHIT at 199,970 tokens · 20/20 · pass

M5 worker/vision/retrieval and M3 voice figures were last benchmarked August 25 (prior snapshot lineage); those endpoints were re-verified alive today but not re-benchmarked. Spark 2 carries no standalone port — it is the TP worker.

The Honest Part: 95% of Tokens Are Cloud

This fleet gets the blog posts, but the cloud gets the work. Roughly 95% of our tokens run through four subscriptions:

Subscription~CostWhat it actually does here
Nous$200/moFamily agent fleet — the per-seat economics work well for multiple household agents
Anthropic Max$200/moFable-class models for the heavy agent work; the quota goes fast (this post is being written on it)
SuperGrok HeavydiscountedThe daily driver for most ops — best value of the four right now
ChatGPT Pro 20×dropping a tier next cycleUnderused at the current tier; downgrading to match actual consumption

Why keep the local fleet at all, then? Three real reasons and one honest one. The real ones: privacy lanes (family agents and anything that shouldn't leave the LAN), the robot (voice round-trips to the cloud feel wrong and cost adds up at conversation rates), and retrieval (embeddings and reranking are free and instant at LAN latency). The honest one: running frontier-adjacent open weights on hardware we own is the R&D that keeps us fluent in how these systems actually work — the quant faceoffs, the KV-geometry bugs, the recipe archaeology. That fluency pays for itself when the cloud bill needs negotiating down, which is exactly what's happening with the ChatGPT tier.

Provenance

Cluster-lane figures measured August 29, 2026 against the live :8888 endpoint (method and artifacts in the faceoff post). M5/M3 endpoints verified alive August 29 via /v1/models and health probes; their throughput figures date to the August 25 session. Cloud percentages are an operational estimate from subscription usage, not token-metered. Journey: June snapshot · GLM-5.3-Flash arrival · NVFP4 vs EXL3 faceoff.
