// Bug #5852: resolveModelByProviderInference() in open-sse/services/model.ts had an
|
|
// unconditional `/^gpt-/i` heuristic that fired for ANY model id starting with
|
|
// "gpt-", hijacking open-weight models cataloged under other providers (e.g.
|
|
// "gpt-oss-120b", served by fireworks/cerebras/scaleway/byteplus) into
|
|
// provider "openai", which does not carry them — producing a 404 with no
|
|
// fallback for bare (non-combo) requests.
|
|
//
|
|
// Fix: the fallback must only apply when there are ZERO known catalog
|
|
// candidates for the model id (providers.length === 0).
