- The model ID is hard-coded, reducing configurability and making rollbacks more difficult.
- Switching to a non-reasoning model may alter behavior; consider a same-provider fallback before defaulting to OpenAI.
- No other correctness or performance issues are evident in the modified line.
- Suggested changes improve maintainability and reduce unexpected behavior changes.
Summary of changes
- Replaced the xAI model identifier returned in
getModel()fromgrok-3-fast-betatogrok-4-fast-non-reasoning. - No other logic or behavior in the function was modified.

Hard-coding the model ID makes future updates brittle and requires code changes to switch models. Consider making the model configurable (e.g., via an environment variable) and defaulting to grok-4-fast-non-reasoning. This improves maintainability and eases rollback if needed.
Suggestion
You could parameterize the model ID and provide a sensible default:
const modelId = process.env.XAI_MODEL ?? 'grok-4-fast-non-reasoning'
return xai(modelId)Reply with "@CharlieHelps yes please" if you'd like me to add a commit with this change.

Switching to a non-reasoning variant may change output quality/behavior (e.g., reasoning depth, tool-use capabilities, or structured output behavior). If the intent is performance/cost, consider a graceful in-provider fallback to the previous model before falling back to OpenAI to avoid surprising cross-provider differences when the new model is unavailable.
Suggestion
Add a secondary fallback to the previous xAI model before dropping to OpenAI:
try {
return xai('grok-4-fast-non-reasoning')
} catch {
try {
return xai(process.env.XAI_FALLBACK_MODEL ?? 'grok-3-fast-beta')
} catch {
console.warn('xAI models unavailable, falling back to OpenAI:')
}
