Can't find valid model with --model

[mausch]

Description

$ opencode --model openrouter/hunter-alpha run "hello"
ProviderModelNotFoundError: ProviderModelNotFoundError
 data: {
  providerID: "openrouter",
  modelID: "hunter-alpha",
  suggestions: [ "openrouter/hunter-alpha" ],
},

      at getModel (/$bunfs/root/src/index.js:185999:15)

Error: Model not found: openrouter/hunter-alpha. Did you mean: openrouter/hunter-alpha?

Issues:

• model is valid but reported as invalid i.e. this lookup looks broken
• it's suggesting the same model I told it to use i.e. suggestion looks broken

This issue might be a duplicate of existing issues. Please check:

• Model IDs with slashes are broken #15668: Model IDs with slashes are broken - same ProviderModelNotFoundError when the model ID contains slashes (e.g. provider/model-name)
• CLI run --model fails for namespaced models with : or multi-segment paths (truncates modelID → ProviderModelNotFoundError) #3993 (closed): CLI --model fails for namespaced models with multi-segment paths - same root cause where the model ID parser truncates the modelID after the first /

The openrouter/hunter-alpha case looks like the same parsing bug where the model ID portion is being mishandled.

This is not #15668 apparently.
I can get e.g. github-copilot/gpt-5-mini to work, but openrouter/hunter-alpha for some reason doesn't.
