Swarm Multi-Agent Topology
Best Paired With: Gemini 3.8 Flash for subagent swarms
High-confidence planning eliminates hallucinated stages and coordinates complex multi-worker Task Programs effortlessly.
Supervises parallel Git worktrees and verifies build assertions before promoting code to dev.
What Developers & Practitioners Are Saying
Real-world field observations, production strengths, and developer consensus
"OpenAI's major generational platform update. Exceptionally balanced between raw reasoning depth, fast throughput, and reliable tool calling."
Verified Real-World Strengths
- 69.5% on SWE-bench Verified with zero configuration overhead
- Crisp, concise code explanations without unnecessary boilerplate
- Native integration with modern developer toolchains
Production Caveats & Gaps
- Priced above utility flash models, making it less ideal for raw grep tasks
- Requires explicit instruction to format diffs as unified patches
