Problem

Currently opencode cli doesn't provide any helpfull messages if you mistyped model name, instead it just throws raw error. It also ignores such edgecase as empty string --model "" or --model " "

$ opencode run --model "anthropic/claude-sonet-4-5" "How pointers work in Go?"
1051 |     const provider = s.providers[providerID]
1052 |     if (!provider) {
1053 |       const availableProviders = Object.keys(s.providers)
1054 |       const matches = fuzzysort.go(providerID, availableProviders, { limit: 3, threshold: -10000 })
1055 |       const suggestions = matches.map((m) => m.target)
1056 |       throw new ModelNotFoundError({ providerID, modelID, suggestions })
                   ^
ProviderModelNotFoundError: ProviderModelNotFoundError
 data: {
  providerID: "anthropic",
  modelID: "claude-sonet-4-5",
  suggestions: [],
},

      at getModel (src/provider/provider.ts:1056:13)

I suggest using existing validation method, making cli error output much prettier and helping.

$ opencode run --model "anthropic/claude-sonet-4-5" "How numbers work?"
Model not found: anthropic/claude-sonet-4-5
Try: `opencode models` to list available models
Or check your config (opencode.json) provider/model names

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

  • #8460: API doesn't report invalid model errors via event stream - addresses error reporting when invalid models are used
  • #7958: ProviderModelNotFoundError for custom provider in GitHub Action - shows the same raw error being thrown without helpful context
  • #9203: Feature: Support disabled_models config to hide specific models - related to model validation and availability checking

Feel free to ignore if none of these address your specific case.
