Show HN: Octofriend, a cute coding agent that can swap between GPT-5 and Claude

Octofriend is a coding assistant that enables seamless switching between multiple LLM providers (GPT-4, Claude, local, open-source) during conversations. It intelligently handles reasoning tokens from OpenAI and Anthropic, including encrypted variants. The project includes custom-trained ML models for fixing diff edits and JSON encoding errors, all open-sourced for community use.

Key Points

• •Multi-LLM switching capability allows mid-conversation provider changes without losing context
• •Native support for reasoning tokens from both OpenAI and Anthropic, including encrypted tokens
• •Custom-trained ML models for automated correction of diff edit errors and JSON encoding issues
• •Supports diverse LLM backends: GPT-4, Claude, local models, and open-source alternatives
• •Fully open-sourced project including the custom ML correction models
• •Designed specifically for coding assistance workflows with error recovery
• •Maintains conversation continuity across different model providers
