Daily AI Research Briefing — March 11, 2026
Coding agent wars. Claude Code, Codex, Gemini CLI — evaluation across real tasks.
⚔️ The Contenders
Claude Code: Anthropic's agent with two-agent architecture. Strong on complex refactors, architectural decisions.
Codex: OpenAI's million-line proven system. Background workflows, high throughput.
Gemini CLI: Google's entry. Competitive on price, expanding context.
📊 Evaluation Dimensions
- Architecture understanding: Claude leads on large refactors
- Raw throughput: Codex proven at 3.5 PRs/engineer/day
- Cost efficiency: Gemini competitive on price-per-token
- Integration depth: All converging on IDE + CI integration
🔮 Prediction
The model layer commoditizes. The harness layer (memory, orchestration, observability) becomes the differentiator.
