Version Updates

Features in This Version

• Rebuilt the core toolchain for stronger compatibility across mainstream models and higher tool-call success rates on Windows.

Core Capability Upgrades

Fully Refactored Core Toolchain

The official file editing tool was deeply tuned for GPT-family models, which can lead to weaker compatibility with other mainstream models. This version introduces a broad toolchain refactor focused on wider model support and better execution reliability.

• Better compatibility with most mainstream models
• More streamlined tool invocation flow for higher execution efficiency
• Deeply optimized Windows toolchain behavior for stronger stability and higher call success rates

Intelligent AI Context Management

This release introduces advanced AI context management strategies with dynamic context compression.

• Dynamically compresses context when the same file is read multiple times
• Preserves the latest file state as priority context
• Reduces prompt length and avoids context pollution
• Improves reasoning efficiency and multi-step task stability

AI-Compatible Experience

• Works the same way as OpenAI Codex
• Zero learning curve for seamless switching between AI coding assistants

Proprietary AI Diff Algorithm

Includes a self-developed high-efficiency edit_file diff algorithm.

• Improves EditFile pass rates while preserving editing accuracy
• Reduces retry frequency
• Completes multi-step programming tasks in fewer turns

High Cost Performance

• Multiple AI plans with flexible options
• Affordable pricing with no speed limits
• Strong balance between performance, cost, and developer experience

Tips

You can provide filepath + space + usermessage to automatically load file content into the conversation context.

• Reduces the number of dialogue turns
• Saves tokens
• Improves programming efficiency
