2470 Tinyagent Baseurl Integration 3deedd34

Handoff: TinyAgent base_url Integration

Date: 2026-02-11 Status: TinyAgent updated, PyPI release pending

What Changed

TinyAgent added native base_url support for OpenAI-compatible endpoints:

• Python provider: stream_openrouter now accepts base_url parameter
• Rust binding provider: stream_alchemy_openrouter / stream_alchemy_openai_completions
• New OpenRouterModel class for configuration

Files to Modify in TunaCode

1. /root/tunacode/src/tunacode/core/tinyagent/openrouter_usage.py

Current: Custom HTTP wrapper that hardcodes OPENROUTER_API_URL Action: Replace with TinyAgent's native stream_openrouter using OpenRouterModel

2. /root/tunacode/src/tunacode/core/agents/agent_components/agent_config.py

Current: _build_tinyagent_model() only allows openrouter: provider prefix Lines 243-262: Hardcoded check rejects other providers Action:

• Remove the if provider_id != "openrouter": check
• Support arbitrary provider:model format
• Pass base_url from config to TinyAgent

3. /root/tunacode/src/tunacode/core/agents/agent_components/agent_config.py

Current: _build_stream_fn() wraps custom stream_openrouter_with_usage Action: Replace with TinyAgent's native streaming (once usage data confirmed)

Configuration Flow

User sets base URL via:

• --baseurl CLI flag → stored in OPENAI_BASE_URL env var
• User config: user_config.env.OPENAI_BASE_URL

This needs to be passed through to TinyAgent's OpenRouterModel(base_url=...)

Testing Notes

TinyAgent team confirmed working with:

• OpenRouter default endpoint
• Chutes endpoint: https://llm.chutes.ai/v1/chat/completions
• Model: Qwen/Qwen3-32B

Migration Path

1. Update TinyAgent dependency when PyPI releases
2. Replace custom wrapper with native TinyAgent streaming
3. Update model validation to allow arbitrary providers
4. Thread base_url from config through to TinyAgent
5. Remove openrouter_usage.py if native usage data works
