🎉 Gemini Provider Now Fully Functional

Three critical bugs have been fixed in v1.9.3, making the Gemini provider production-ready with complete streaming support.

Fixed

1. Model Selection Bug (cli-proxy.ts, anthropic-to-gemini.ts)

  • Issue: Proxy incorrectly used COMPLETION_MODEL environment variable containing claude-sonnet-4-5-20250929 instead of Gemini model
  • Fix: Ignore COMPLETION_MODEL for Gemini proxy, always default to gemini-2.0-flash-exp
  • Impact: Gemini API now receives correct model name

2. Streaming Response Bug (anthropic-to-gemini.ts:119-121)

  • Issue: Missing &alt=sse parameter in streaming API URL caused empty response streams
  • Fix: Added &alt=sse parameter to streamGenerateContent endpoint
  • Impact: Streaming responses now work perfectly, returning complete LLM output

3. Provider Selection Logic Bug (cli-proxy.ts:299-302)

  • Issue: System auto-selected Gemini even when user explicitly specified --provider anthropic
  • Fix: Check options.provider first and return false if user specified different provider
  • Impact: Provider flag now correctly overrides auto-detection

Verified Working

All providers tested end-to-end with agents:

  • ✅ Gemini provider with streaming responses
  • ✅ Anthropic provider (default and explicit)
  • ✅ OpenRouter provider
  • ✅ ONNX local provider

Quick Start with Gemini

# Setup Gemini API key
export GOOGLE_GEMINI_API_KEY=your_key_here

# Use Gemini (2-5x faster, 70% cheaper than Claude)
npx agentic-flow --agent coder --task "Write function" --provider gemini

# Gemini with streaming
npx agentic-flow --agent coder --task "Build API" --provider gemini --stream
