5.6 series support

[codereptile]

(joke) Omg, 5.6 came out like 5 minutes ago, why is still unsupported

[raine]

I can't access it yet but blindly updated the docs based on how codex repo uses it.

I've updated the proxy to v0.1.8 and can access gpt-5.6-terra. However, when using gpt-5.6-luna, I receive the following error in the proxy console: Model not found gpt-5.6-luna-free-1p-codexswic-ev3. I have access to Luna through the Codex CLI.

EDIT: Upgrading now. Whoops.

There's something weird going on here. I have access via codex, but not via claude-code-proxy.

When I try to specify it I get

Please try the latest version - everything seems to work.

Some questionable changes were needed so there's maybe a slightly heightened risk of getting your account banned / timed out

Please don't blame me if that happens :)

Thank you for all your work on this. 🤗

Works now with the latest version. Thanks! 👍

I've observed so far that gpt-5.6-sol in CC might overuse subagents, sometimes in a strange way, compared to gpt-5.5. Interested in hearing if others have similar findings.
