Model not found

Error message

Model not found

What it means

Chat resolves the model via GetModelInfo(supplierName, modelId) and returns this error when it returns nil, meaning the model ID is unknown for that supplier. The client cannot be initialized without model metadata such as MaxTokens.

Solutions

1. Call GetModelInfo(supplierName, modelId) yourself first and confirm it is non-nil
2. Refresh the supplier's model list and pick a valid modelId
3. Update stored chat configurations that reference removed models

Example fix

// before
err := askai.Chat(ctx, chatId, supplier, "gpt-3.5-turbo-0301", content, true)
// after
if askai.GetModelInfo(supplier, "gpt-4o-mini") == nil {
    return errors.New("model unavailable for supplier")
}
err := askai.Chat(ctx, chatId, supplier, "gpt-4o-mini", content, true)

if askai.GetModelInfo(supplierName, modelId) == nil {
    return fmt.Errorf("model %q unavailable for supplier %q", modelId, supplierName)
}

When it happens

Trigger: Calling Chat with a modelId that does not exist under the given supplier (wrong ID, model removed from the supplier's catalog, model listed under a different supplier).

Common situations: Supplier deprecated/renamed a model (e.g., GPT model version retirement); hardcoded modelId after switching suppliers; stale chat records pointing at a deleted model entry.
