Since it requires two PRs ask agent to:

Please run Agent Canvas from PR <https://github.com/OpenHands/OpenHands/pull/16147> with the SDK pointed at <https://github.com/OpenHands/software-agent-sdk/pull/4287>.

I already have other Agent Canvas stacks running, so use isolated ports and isolated state. Add 550 to the usual ports:

- UI/ingress: 8550

- backend: 18550

- automation: 18551

- static frontend: 3551

Use a separate state directory, pin the secret key for that state directory, and do not disturb any existing running stacks.

After it is running, verify:

- <http://localhost:8550> returns 200

- backend /api/settings returns 200 with the generated session API key

`- key frontend JS assets return 200, not 404````

Then test the default Model Router flow: 1. Open localhost 2. Configure one working active LLM profile. 3. Go to Model Router / meta-profile settings. 4. Click Add meta-profile. 5. Pick one of the pareto defaults. 6. Confirm the checkbox is enabled by default. 7. Save it. 8. Confirm it creates the missing router LLM profiles by reusing the active provider settings. 9. Start a conversation and ask:

Use the model router to classify and route the following task: fix a tricky Python test failure in a large codebase.

10. Confirm the tool runs correctly.

When I did step 9, I got the following error.

litellm.AuthenticationError: AuthenticationError: Litellm_proxyException - {"error":{"message":"LiteLLM Virtual Key expected. Received=****, expected to start with 'sk-'.","type":"auth_error","param":"None","code":"401"}}

Don’t we need to set up the model router so that it works with whatever language models the user sets up? We also can’t assume that the user will have access to the OpenHands litellm proxy — some people might be just using openrouter, etc. so we’ll need instructions for how to use the router in that case. I think one way we could do this is have it so that we have documentation for a “happy path” where they set it up with an OpenHands API key a single time and it works easily, or a more customized path where they set up their own language models in whatever way. Ideally both should be able to start from a blank installation of openhands.

I left a review comment to that effect here. Thanks! And happy to re-review once it’s modified: https://github.com/OpenHands/docs/pull/687

will try to reproduce the 401 error

‘duplicate’ menu command helps, but I’ve also come around to the idea that from a user perspective, it makes sense to “connect a provider “ and then add models from it

it's easy, and less messing around with keys
