PR authors are responsible for ensuring that after merging, all GitHub Action jobs fully pass. A lot of the time, failures are just flakes and simply re-running the failed jobs will fix it. If re-running failed jobs is attempted, PR authors are responsible for ensuring it passes.

LGTM — straightforward vLLM image version bump with matching perf-changelog entry.

Extended reasoning...

Overview

This PR bumps the minimaxm2.5-fp8-b200-vllm recipe image from vllm/vllm-openai:v0.19.0-cu130 to vllm/vllm-openai:v0.21.0 in .github/configs/nvidia-master.yaml, and adds a corresponding entry to perf-changelog.yaml.

Security risks

None. This is a configuration-only change that updates a container image tag for a benchmark recipe. No code paths, auth, or permissions are touched.

Level of scrutiny

Low scrutiny is appropriate. This is a one-line image tag change that follows the exact same pattern as multiple recently merged sibling PRs (#1404, #1394, #1416 visible in recent commit history). The PR has the full-sweep-enabled label, so CI will validate the recipe end-to-end.

Other factors

The bug hunting system found no issues. The perf-changelog entry is correctly formatted and references the right PR number. Nothing here warrants human-reviewer attention.
