+# Multi-Provider Code Review
+
+This feature allows the GitHub Action to run code reviews simultaneously with multiple AI providers and then synthesize their results into a comprehensive review.
+
+## How It Works
+
+1. **Parallel Reviews**: The workflow runs reviews with multiple providers simultaneously using `Promise.all`
+2. **Aggregation**: All individual reviews are collected and formatted
+3. **Synthesis**: A designated synthesis model combines overlapping feedback, highlights unique insights, and removes duplicates
+
+## Configuration
+
+The providers are configured via the `REVIEW_PROVIDERS` environment variable in `.github/workflows/review.yml`:
+
+```yaml
+REVIEW_PROVIDERS: "opencode/big-pickle,opencode/grok-code,opencode/minimax-m2.1-free,opencode/glm-4.7-free"
+```
+
+### Current Free Providers
+
+- `opencode/big-pickle` - Large reasoning model
+- `opencode/grok-code` - Code-specialized model
+- `opencode/minimax-m2.1-free` - Free tier model
+- `opencode/glm-4.7-free` - Free GLM model
+
+## Adding New Providers
+
+To add or change providers:
+
+1. Edit the `REVIEW_PROVIDERS` variable in `.github/workflows/review.yml`
+2. Use the format `provider/model` (e.g., `opencode/big-pickle`)
+3. Separate multiple providers with commas
+
+## Script Details
+
+The `github/multi-review.ts` script handles:
+
+- Running parallel reviews with error handling
+- 5-minute timeout per provider
+- Graceful fallback if a provider fails
+- Synthesis using the first provider in the list
+- Proper logging and status reporting
+
+## Benefits
+
+- **Comprehensive Reviews**: Multiple perspectives catch different issues
+- **Redundancy**: If one provider fails, others continue
+- **Cost Efficiency**: Uses free providers
+- **Quality Synthesis**: Combines the best insights from all reviews
