Models

ContentAI exposes a curated list of models per provider. You can change the selection any time in Settings — and the choice is stored per provider, so switching providers doesn't lose your preferred model.

Choosing the right model

Blog posts, articles, long-form → Claude Sonnet, GPT-4o, or Llama 3.3 70B
Short social media, taglines → Llama 3.1 8B Instant or GPT-4o-mini
SEO meta descriptions, keywords → Any fast model is fine
Bulk runs for cheap → Groq (free) or GPT-4o-mini
When you need structure / JSON → GPT-4o or Claude Sonnet

Adding a model

To add a model that's not in the dropdown, edit lib/store.ts:

export const providerModels: Record<AIProvider, string[]> = {
  groq: [
    "llama-3.3-70b-versatile",
    "llama-3.1-8b-instant",
    "mixtral-8x7b-32768",
    "your-new-model-here", 
  ],
  // ...
};

The model ID must match the one the provider's API expects.

Changing the default model

The defaults are set in lib/store.ts in the selectedModels initial state. Update the string for any provider:

selectedModels: {
  groq: "llama-3.3-70b-versatile",        // default
  google: "gemini-2.5-flash",
  openai: "gpt-4o-mini",
  anthropic: "claude-3-5-sonnet-20241022",
}
