Key capabilities
Technical implementation
Intelligent File Discovery
Multi-stage AI workflow identifies relevant files for your plan-mode
- Root folder selection based on task
- Targeted regex pattern groups
- LLM analyzes actual file contents
- Automatic dependency detection
- Files organized into XML for LLM consumption
Multi-Model Planning
Generate multiple implementation approaches using different AI models, then synthesize the best solution
- OpenAI GPT‑5 family (GPT‑5 and GPT‑5 Thinking/Pro), historical o‑series (e.g., o3 variants); Anthropic Claude Sonnet 4 and Opus 4.1; Google Gemini 2.5 Pro - availability and features vary by plan and endpoint (ChatGPT vs API).
- AI architect merges best insights
- Your guidance shapes the merge
Use official vendor docs to confirm features like streaming, function calling, and background mode for each model.
