Not possible to use Anthropic CUA with Stagehand.Agent?

[0thernet]

Haven't yet figured out how to configure this, though it's advertised as a one-line switch. I'd expect to be able to do something like this:

agent = stagehand.agent(
            model="claude-sonnet-4-latest",
            provider="anthropic",
            options={
                "apiKey": os.getenv("ANTHROPIC_API_KEY"),
            },
        )

based on https://docs.stagehand.dev/reference/agent

But this doesn't work, I get
Request failed with status 400: {"error":[{"path":"agentConfig","message":"Expected 'openai' | 'anthropic', received null"}]}

It also seems like you haven't added claude 4 models to https://github.com/browserbase/stagehand-python/blob/main/stagehand/agent/agent.py#L23C1-L25C3 yet?

Another nit: it seems like I have to both provide an apiKey when initializing stagehand.agent, as well as when initializing Stagehand...

stagehand_config = StagehandConfig(
                    modelApiKey=os.getenv("OPENAI_API_KEY"),  
                    # ...
                )
                stagehand = Stagehand(stagehand_config)

# ...
agent = stagehand.agent(
            provider="openai", # seems optional?
            model="computer-use-preview",
            options={
                "apiKey": os.getenv("OPENAI_API_KEY"),
            },
        )

@0thernet I believe the tag claude-sonnet-4-20250514 should work, we're also rolling out 4.5 support in the next release
