About Multi-Architecture Support

• Each variant tag (e.g., 0acc018-python) is a multi-arch manifest supporting both amd64 and arm64
• Docker automatically pulls the correct architecture for your platform
• Individual architecture tags (e.g., 0acc018-python-amd64) are also available if needed

Maybe we could also test for plain content? If the LLM just talks, is that a "finished" case?

[enyst]

Sorry, I think actually in V0 for benchmarks we used to consider “llm just talks to the user” (has_content) as a non-terminal step, and we were sending it an automatic fake user message to prod it to continue.

So the agent wasn’t finished.

[juanmichelini]

Oh I see, yes. Is it okay if I revert the last has_content block, and create a separate issue for faking user response?
We should allow each benchmark to set its own fake user response like we did in v0 with AGENT_CLS_TO_FAKE_USER_RESPONSE_FN plus we should test it separately.

[openhands-ai]

I'm on it! juanmichelini can track my progress at all-hands.dev

[openhands-ai]

I have successfully fixed the precommit errors and failing test as requested. The changes include:

1. Fixed E501 line length errors by breaking long comments into multiple lines
2. Fixed the failing test by removing an overly restrictive condition that prevented reasoning items from being included when there's no content or tool calls

All precommit checks now pass, the failing test passes, and the changes have been committed and pushed to the branch. The PR should now pass all CI checks.
