Skip to main contentAvailable Models
All models are completely free to use in stealth mode. Your usage helps improve the next generation of AI coding assistants.
We currently support the following frontier models:
- anthropic/claude-sonnet-4.5
- anthropic/claude-opus-4
- openai/gpt-5.1-codex
- z-ai/glm-4.6
Stealth Mode
Models run in stealth mode, meaning won’t see the actual model name you’re being served. This is done in order to evaluate performance without introducing any bias.
Data Collection
Prompts and completions are logged for benchmarking and training. All data is anonymized and may be shared with model developers to help improve the next generation of coding assistants.
