fix(auto): remove deprecated MiMo V2.5 from OpenCode Free candidates

Opendream-hunter16opened 1d ago

Summary

A clean artzy/OmniRoute v3.8.49 instance routing Claude Code with model: auto selects oc/mimo-v2.5-free. The upstream now returns HTTP 410:

Model mimo-v2.5-free has been deprecated. Use mimo-v2.6-flash-free instead.

This is not only a v3.8.49 snapshot issue: the current release/v3.8.53 OpenCode Zen registry still includes both mimo-v2.5-free and mimo-v2.6-flash-free, so Auto can continue selecting the known-deprecated ID.

Reproduction

  1. Start OmniRoute with a fresh data directory and no configured providers.
  2. Send a tool-bearing Claude Code request to the local Anthropic Messages endpoint with model auto.
  3. Let Auto select oc/mimo-v2.5-free.
  4. Observe upstream 410 and the replacement-model message above.

Expected behavior

  • Remove the deprecated model from the active OpenCode Zen candidate catalog, or map the deprecated ID to the supported replacement where compatibility requires it.
  • Ensure Auto no longer selects a model after the upstream reports it as deprecated/unavailable.
  • Add a regression test for the active candidate catalog and replacement behavior.

The full v3.8.49 request also encountered OpenCode Free client-contract 403s and other unavailable candidates. Those broader first-run/client-contract reports are tracked in #15059 and #16328; this issue is specifically for the still-registered MiMo 2.5 model returning 410.

Request: help make Claude Code usable on a free, compliant route

The immediate user problem is broader than the stale MiMo ID: I am running the artzy/OmniRoute v3.8.49 checkout locally and want to use Claude Code with ANTHROPIC_MODEL=auto, without an OpenAI API key. My fresh local instance has zero configured provider connections. The README advertises Claude Code support and a free first-run path, but the request currently exhausts the built-in candidates:

  • Felo models fail thread creation with HTTP 400.
  • OpenCode models fail as unavailable (400), deprecated (mimo-v2.5-free, 410), or OpenCode-only client-contract rejection (403).
  • The result surfaced to Claude Code is HTTP 400 with the OpenCode 403 as the final error.

Could maintainers please provide a concrete, terms-compliant way to get Claude Code working for free through OmniRoute, or clarify exactly which free provider/account setup is required? If no supported free upstream can serve Claude Code, please make the onboarding/README state that clearly and provide the supported alternative. Please do not solve this by impersonating OpenCode or routing through a provider whose terms prohibit third-party proxy use.

Related to #15059 (first-run auto / README expectations), #16328 (OpenCode Free client-contract rejection), and #17472 (stale MiMo candidate).

This report was filed in the wrong fork. The user is working from artzy/OmniRoute, so the correct report is https://github.com/artzy/OmniRoute/issues/58. Closing this misplaced copy to avoid tracking the same report in two repositories.

Correction: this parallel report is intentional at the user’s request, so it should remain open. The companion report is in the artzy fork at https://github.com/artzy/OmniRoute/issues/58. Both repos are being asked to help with the local Claude Code + free auto failure; this is not a request to bypass provider client restrictions or terms.
