Catalog

| OpenAI GPT-5.5 | Advanced coding, research, and long-running agentic work. |
| OpenAI GPT-5.6 Sol | OpenAI's flagship for ambitious agentic work. |
| OpenAI GPT-5.6 Terra | Balanced OpenAI model for efficient, high-volume work. |
| OpenAI GPT-5.6 Luna | Fast, affordable OpenAI model for everyday work. |
Picking a model
- Start with Sonnet. It's the right call most of the time.
- Upgrade to Opus when a task is hard, multi-step, or the stakes are high enough that you'd want a second opinion.
- Drop to Haiku when you want fast and cheap — short summarizations, quick lookups, automation.
- Try GPT-5.5 for advanced coding, research, and long-running agentic work.
Where to set the model
- Org-level default — in org settings. Every project in the org picks this up unless overridden.
- Per-project — override in project settings. Lets you use Opus for your most demanding project while keeping Sonnet everywhere else.
