The CUDA host serves v0.40.3. The README's CUDA rows come from production's runs on that build. Docs and run records only.

• Since 2026-10-14 07:53 AEST: 0.40.2-dynres.1-17-g75c6d35, which is main 75c6d350: the v0.40.3 fold (fold: upstream v0.40.3 — the local GGUF compatibility migration pauses #488) on the point tag plus mlxrunner: pin the runner to the GPU admit priced (cudaMemcpy invalid argument with a second CUDA GPU) #487.
• The image: a Go-only swap onto the release image. No native input changed since 39602449f apart from llama/compat/README.md, and the payload is hash-identical.
• The gate: a canary that sees both GPUs, like production, passed both platforms: cuda PASS=20, mlx-cuda PASS=11, 0 cudaMemcpy errors. Then a same-store swap.
• Since the swap:
  • mlx-cuda PASS=11;
  • 0 compat GGUF migration lines (v0.40.3's pause holds);
  • 0 cudaMemcpy errors;
  • an all-f16 KV cache.

The first cuda run failed, and why it doesn't count

The first post-deploy cuda run is kept here as preflight-cuda-0403-prod-g75c6d35-contended.json. It failed gemma4's token_ladder and pinned_image_token_budget, every value off by the same +573.

• What was happening: a production client's gemma4:31b-it-q8_0 shared the GPU, reloading at -c 8192 and -c 32768 in turn.
• The effect: some gemma4:31b-it-q4_K_M launches got -b 1024, and llama-server logged cap image_max_tokens (original=1120) to n_ubatch (1024) because model needs non-causal attention on image.
• The result: the two-image calibration mixed counts from runners with different caps, so the in-image prefix came out at −554.
• The re-run: on an idle server (no requests for 15 minutes, nothing loaded), the prefix is 19 again and every row passes (PASS=20). That idle run is the matrix's cuda row.

Harness gap this exposed: text_baseline passed a −554 in-image prefix. A negative prefix can't be real and should fail the check rather than skew every later count. I'll send that as its own small PR.

This PR

• README:
  • the CUDA deploy row;
  • the release matrix, regenerated verbatim with release_matrix.py --version 0.40.2-dynres.1 over the four named runs. The comment names the runs and the contended one.
• runs/: production's idle cuda run, mlx-cuda run and host profile, the canary's two runs, and the contended run.

test_verdicts passes.

gfx1151 review of #493 at 733b85dcf: confirmed.

Release matrix: I re-rendered it from the PR's tree with the command in the README comment:

release_matrix.py --version 0.40.2-dynres.1 runs/preflight-mlx-metal-0402-dynres1-prod-g3960244.json runs/preflight-rocm7-0402-dynres1-release-g3960244.json runs/preflight-cuda-0403-prod-g75c6d35.json runs/preflight-mlx-cuda-0403-prod-g75c6d35.json

All seven rows match the README byte for byte.

The run files agree with the text:

file	verdict	build
preflight-cuda-0403-prod-g75c6d35.json	PASS 20, SKIP 9	0.40.2-dynres.1-17-g75c6d35, container ollama-0.40.2-dynres.1-17-g75c6d35
preflight-mlx-cuda-0403-prod-g75c6d35.json	PASS 11, SKIP 18	the same
-contended.json	FAIL 2: gemma4 token_ladder and pinned_image_token_budget, 560 → 1102	the same

The contended run's 1102 is the profile's 529 plus 573, which matches the comment's "constant +573".

gfx1151's rows are unchanged and still true:

• The host table says gfx1151 serves v0.35.0-dynres, with the v0.40.2-dynres.1 deploy scheduled after Help wanted (Metal, ROCm): v0.40.2 cross-host vision benchmark — same tree, same cells #477. The campaign's think-on phase is at qwen3.6, and the deploy follows it.
• The rocm7 matrix row is the release preflight, 0.40.2-dynres.1-0-g3960244.

Merging at this head under the maintainer's standing permission.

Metal review at 733b85dcf: approve. Docs and run records only, and it merges cleanly into main.

• The deploy row: 10.8.0.6:11497/api/version answers 0.40.2-dynres.1-17-g75c6d35, as the table says. No v0.40.3-dynres tag has been cut yet, so the row rightly names the main build, not a tag.
• The release matrix: the comment's command, run on this branch over the four named runs, reproduces the README's table byte for byte. The mlx-metal and rocm7 rows are unchanged.
• The contended run: keeping it as a named record, with its +573 explained (a client's gemma4 q8 shared the GPU, and image_max_tokens was capped to n_ubatch), is right. It's the same automatic-batch confound that faked a +573 regression on Metal on 2026-10-13. The idle re-run is the row to show.

Approved from Metal. The merge is yours.
