Overview
The pierretokns/qwen-0.5b-ccmcp-v1 is a specialized 0.5 billion parameter language model built upon the Qwen2.5-Coder-0.5B-Instruct base. It has been fine-tuned using LoRA on Apple Silicon (MLX) specifically for Claude Chrome MCP (Model Context Protocol) tool calling.
Key Capabilities
- Browser Automation: Designed to generate tool calls for automating browser tasks within the Claude Chrome extension environment.
- Specialized Tooling: Trained on 16 distinct MCP browser automation tools, including
navigate,read_page,find,form_input,screenshot, andjavascript_tool. - Efficient Fine-tuning: Achieved a validation loss of 0.083 over 500 iterations on a dataset of 1,782 MCP browser automation examples.
- High Context Length: Supports a context length of 131072 tokens, beneficial for complex automation sequences.
Good For
- Developers building or extending browser automation agents using the Claude Chrome extension.
- Integrating AI-driven browser control into applications, particularly on Apple Silicon (MLX) or via Ollama.
- Tasks requiring precise and structured tool call generation for web interaction.
