v0.0.1 Release

Claude-to-Chutes Proxy v0.0.1 Release Notes

Overview

Claude-to-Chutes Proxy v0.0.1 is the first stable release of this project, implementing a complete bridge between Anthropic Claude API format and Chutes/OpenAI API format. This version includes optimized support for multiple mainstream models, comprehensive error handling, and production-ready deployment solutions.

Version History

Base Commit: v0.0.1 tag is based on commit d54dc79, containing the complete development history from initial version to release.

Major Features

🚀 Core Architecture

1. Protocol Conversion

• ✅ Anthropic ↔ OpenAI Compatibility: Full support for Anthropic v1/messages to OpenAI v1/chat/completions request/response conversion
• ✅ Streaming Support: Native Server-Sent Events (SSE) streaming responses
• ✅ Tool Calling: Support for both non-streaming and streaming tool calls

2. Model Provider Support

• DeepSeek V3.1: Full THINKING mode support (:THINKING suffix)
• LongCat: Dedicated GPT-OSS style tool parser
• Moonshot/Kimi: Intelligent model name case correction
• Cloud Code MCP: Tool markup parsing support

3. Tool Processing System

• Multi-provider Tool Parsing: DeepSeek, LongCat, MCP, and various markup formats
• Streaming Tool Parsing: Real-time sglang.FunctionCallParser integration
• Tool Name Normalization: Built-in synonyms and fuzzy matching

🚀 Performance Optimization

1. Intelligent Cache System

• Persistent Model Discovery: /v1/models results cached to disk
• Memory + Disk Dual Cache: Disk fallback during network failures
• TTL Validation: Prevents stale cache issues

2. Network Optimization

• Shared HTTP/2 Client: Connection reuse and pooling
• 429 Rate Limiting: Intelligent retry strategies
• HTTP/2 Support: Enabled by default for performance

3. Error Handling System

• Streaming Session Management: Prevents connection termination
• Model ID Correction: Automatic model name case correction
• 404 Retry Mechanism: Smart retry when model discovery fails

🛠️ Deployment & Operations

1. Docker Support

• Docker Compose: Complete production environment configuration
• GHCR Prebuilt Images: ghcr.io/takltc/claude-code-chutes-proxy:0.0.1
• Health Checks: Built-in health check endpoints

2. Configuration Management

• Environment Variables: Rich configuration options
• .env File Support: Easy development and production environments
• Admin Endpoints: Cache management and monitoring

Technical Specifications

🎯 Intelligent Model Recognition

# Supported model identification patterns
model = "deepseek-ai/DeepSeek-V3.1:THINKING"  # THINKING mode
model = "deepseek-ai/DeepSeek-V3.1"           # Standard mode
model = "longchat-longcat"                    # LongCat tools
model = "moonshot-v1"                        # Moonshot case correction

🛠️ Tool Parser Architecture

1. MCP Tool Parsing: Cloud Code <|tool_calls|> markup
2. LongCat Parsing: GPT-OSS style parser
3. DeepSeek Parsing: Native tool call support
4. Universal Tool Parsing: Adaptive model-specific formats

🔄 Streaming Processing

• Thinking Block Processing: DeepSeek reasoning mode streaming
• Streaming Tool Arguments: Real-time input parameter parsing
• Session Management: Connection and state preservation

Benchmarking Environment

System Requirements

• Python: 3.11+ (Supports Python 3.10 - 3.13)
• Dependencies: See requirements.txt
• HTTP Client: httpx 0.27.2 (HTTP/2 enabled)

Performance Metrics

• Connection Latency: HTTP/2 optimized connection setup
• Cache Hit Rate: Model discovery cache reduces 95% API calls
• Error Recovery: Smart retry improves success rate
