   Thanks for raising this. I think this is a duplicate of #48991, an open issue that asks for the same configurable model fallback and says it supersedes #7602.

   Possible duplicates and closely related issues, most likely first:

   • [FEATURE]: Configurable model fallback on transient errors and timeouts #48991: open request for configurable model fallback on transient errors (5xx, 429, network failures, timeouts), with global or per-agent fallback lists. It is the successor to [FEATURE]: Native Model Fallback / Failover Support #7602.
   • [FEATURE]: Native Model Fallback / Failover Support #7602: the original model fallback/failover request, closed as not planned. PR feat(opencode): add LLM provider fallback chain #26292 was linked to it and was not merged.
   • Preserve HTTP status on UnknownError so plugins can fallback #47039: would keep the HTTP status on provider errors so that fallback plugins can tell when to switch models.
   • [FEATURE]:Auto-Failover for Rate Limit Resilience #42513: a narrower request for failover between multiple API keys for the same provider and model.
   • docs(ecosystem): add OpenCode Model Router (port of #53448) #54395: PR adding the "OpenCode Model Router" plugin to the ecosystem docs, which may cover this use case for now.

   It would help to add your use case or a 👍 to #48991, so all the interest is tracked in one place. The bot will close this issue as a duplicate in 1 day unless you reply explaining how your request differs.

   We haven't heard back since the duplicate notice, so I'm closing this as a duplicate of #48991. That issue is still open and asks for the same thing: configurable fallback to other models when a model errors, is rate-limited or times out. It also replaces #7602.

   Please add your use case or a 👍 to #48991 so all the interest is tracked in one place. If your request is actually different, reply here and explain how, and we can reopen this.
