Available models

Model	Provider	Profile	Thinking/Reasoning	Credit usage
GPT-5	OpenAI	Most advanced coding model	✅ Deep multi-step reasoning	Premium (credits)
GPT-4.1	OpenAI	Fast senior programmer	–	Premium (credits)
GPT-4.1 mini	OpenAI	Fast junior programmer	–	Basic (no credits)
Gemini 2.0 Flash	Google	Fast junior programmer	–	Basic (no credits)
Claude Sonnet 3.7 / 4	Anthropic	Strong quality-speed balance	✅	Premium (credits)
Claude Opus 4	Anthropic	Highest-quality reasoning	✅	Premium (credits)

You may occasionally see experimental / stealth models (e.g., Horizon Alpha). Availability changes—watch our socials for announcements.

If you’re iterating rapidly or doing light edits, choose a Basic model to avoid credit usage. Switch to a Premium model for complex refactors, tricky bugs, or multi-step integrations.

Quick guidance

Speed first (UI copy, small edits, quick prompts): GPT-4.1 mini or Gemini Flash 2.0
General coding (features, refactors, tests): GPT-4.1 or Claude Sonnet
Hard tasks (deep reasoning, multi-file migrations): GPT-5 or Claude Opus

Thinking-enabled models (e.g., GPT-5, Sonnet/Opus) are slower and consume more credits. Use them when the extra reasoning matters.
