Key Findings Summary

Strengths

Speed: 3x faster than Claude Code on identical tasks (Opus 4.6)
Multi-model: 300+ models via OpenRouter
Open source: Apache 2.0, auditable
Context efficiency: ~90% reduction vs full-file inclusion

Weaknesses

Privacy concerns: Telemetry collects SSH/git data by default
Feature gaps: No checkpoints, auto-memory, or IDE extensions
Benchmark questions: Self-reported scores differ from independent validation
GPT 5.4 stability: "Borderline unusable" despite 81.8% benchmark score

Critical Issues

#2894: Multiple system messages break Qwen 3.5 and similar models
#1318: Telemetry collection concerns
#2893: Ghostty terminal resize bug

Model Recommendations

Best Overall Experience

Claude Opus 4.6 - Fast, stable, reliable

Best Value

MiniMax M2.1 - 47.9% score at $0.30/$1.20 per million tokens

Avoid

GPT 5.4 through ForgeCode - Tool calling failures
Qwen 3.5 - Broken by #2894 until fixed
