Opus 4.8 Support?

[j4ys0n]

Can you add Opus 4.8 to the available models please?

Additionally, Anthropic now has a models endpoint. https://platform.claude.com/docs/en/api/models/list

Thanks for filing this — both halves are now covered:

Opus 4.8: added to the baseline model catalog in #542 (merged today), including marking it latest-of-family and repointing the opus alias to claude-opus-4-8. It'll be in the next deploy.

Models endpoint: Optio has actually been calling GET /v1/models since #493 — the backend probes it, caches the result for an hour, and merges discovered models into the picker. The catch (and likely why you didn't see new models): the probe only worked when an ANTHROPIC_API_KEY secret was configured, so deployments using the recommended OAuth token mode silently fell back to the stale hardcoded list.

#543 fixes that and rounds out the endpoint integration:

• Falls back to CLAUDE_CODE_OAUTH_TOKEN for the models probe when no API key is configured
• Uses the endpoint's display_name for labels and groups discovered models under the right family (Opus/Sonnet/Haiku) in the picker
• Follows pagination

With that merged, future model releases should appear in the picker automatically without needing a catalog update.
