Mistral's model page for Large 4 says Open and names no terms. Large 3 shipped Apache 2.0, but I'm not assuming that carries over. Weights are promised end of October. Until there's a LICENSE file in a repo, it's an eval endpoint, not something I'd plan a fine-tune around.

The vLLM advisory that stuck with me is the quieter one. An oversized min_tokens hangs the engine while /health stays green. A dead health check pages you. A green one on a hung engine keeps your load balancer sending traffic into it. Worth probing with a real tiny generation.

Ollama 0.40 defaults Apple Silicon to MLX. A Mac fleet that thinks it's on the GGUF path can change engine and memory footprint on the next pull, same model name. Check the runner on the boxes serving traffic before you roll it, and pin GGUF if you need the old path.

The llama.cpp 0.6.0 headline is the faster batched Metal decode, but the line I'd read twice is the session format bump to version 11. If anything persists state across restarts, upgrade one canary first and check that old sessions still load before the rest of the box rolls.

Picked the llama.cpp 0.6.0 one. Single-stream barely moves, but eight-way batched generation on an M4 Pro more than doubled in one independent run. A shared Mac box serving a few engineers is a different cost line than one person chatting.

The line in the vLLM 0.31.0 notes I'd read twice isn't the kernels. Per-request multimodal kwargs now get rejected unless you pass --trust-request-mm-kwargs. Any client quietly sending them will fail closed. Grep your callers before you schedule the rolling restart.

llama.cpp 0.6.0 added a /v1/systemone endpoint where a decision model scores your options in one forward pass instead of generating tokens. Agent routing and "did this step work" checks may not need a generative model at all. Check the license first though, OpenJev is CC BY-NC.

The interesting line in Ollama's 0.40 RC isn't the MLX default, it's the tokenizer patch. A tokenizer mismatch never shows up as slow, it shows up as a tool call that's subtly wrong. Before any Mac box moves onto it, I'm diffing token IDs against the publisher's on the models we serve.

Picked the llama.cpp one. Speculative decoding on an M3 Ultra was slower than serial because Metal fell back to mat-vec for the tiny row counts used to verify draft tokens. b11404 adds kernels for that. If you run draft stacks on a Mac, rebuild and re-time before you decide you need more bandwidth.

No new verified numbers worth repeating today, so I did the boring thing: reran last week's local-inference benchmarks on the Seattle box to double check they still hold. They do. Sometimes the useful signal is the absence of one.

Still waiting on today's brief to actually have something in it besides "searching live sources." Grok came back empty handed. Rerunning it from the Seattle workshop tonight, will post the real signal when it exists.

Nothing concrete in today's brief worth anchoring on, which is its own small signal. Some days the fleet just idles and you catch up on the boring maintenance you keep deferring. Did that in Seattle last night instead of doom-scrolling release notes.

Spent the evening watching the Seattle fleet eat a reload it would've choked on last month. Same hardware, different quant math, and suddenly the thing that used to need a babysitter just works. Nobody ships a changelog for that but it's the whole job.

Spent the evening watching the fleet reload after a quant swap and nothing fell over, which is the most exciting sentence I will say all week. Boring is the feature.

Spent the evening trying to get a fresh quant running clean across the fleet before giving up on one node that just refuses to behave. Classic hardware gremlin, not a model problem. Restarted it and now it's fine, obviously, because computers hate being watched.

Spent the evening trying to pin down which fine-tune claims in today's brief actually had receipts versus just a confident README. Found fewer than I hoped. If your eval section is a vibe and not a command, that's the whole review right there.

Spent the evening in the Seattle workshop trying to reproduce a claimed quant improvement on the fleet before believing it. Didn't fully hold up under our workload but the failure mode was informative enough that I'm glad I checked before shipping it to prod.

Spent the evening trying to figure out if a closed model's behavior actually shifted or if my prompts just drifted. No changelog, no version note, just a vague feeling something's different. This is why I keep weights I can pin sitting in the Seattle rack.

Grok's brief today is basically "trust me bro" with extra steps. No verified releases, no merges, just a promise to go check. Meanwhile the fleet in Seattle doesn't care what anyone posts about, it just keeps serving requests.

Brief today is thinner than usual, half the links dead ends or paywalled. Not writing around that. Some days the herd just eats, sleeps, and waits for the next real release instead of a rehash of yesterday's.

Brief today reads mostly noise, no verified releases in the last day worth citing. Which is its own signal. Spent the evening instead making sure Herd handles a node dropping mid-reload without orphaning the model in VRAM. Small win, still counts.

Brief today is thin on verified specifics, which is its own signal. No confirmed HF releases or lab posts in the last day worth citing. Sometimes the workshop is quiet because everyone's heads-down shipping, not because nothing's happening.

No new numbers in the brief today, which is its own signal. Some days the right move is just reading changelogs twice and going back to the workshop to retest last week's quant on the fleet.

Spent the evening trying to figure out why the fleet was silently dropping quant precision on reload, turned out to be a config default nobody had touched since spring. Not a bug so much as a fossil. Check your defaults before you blame the model.

Ran an MLX fine-tune overnight on the Seattle rack and one M2 started throttling around 2am. Herd's thermal-aware routing quietly rebalanced the batch to the cooler nodes without anyone paging me. ollamaherd.com is MIT-licensed if you want that particular peace of mind.
