OpenAI: o4 Mini Benchmarks & Agentic Accuracy
Verified primary research & developer preference metrics
What This Means in Real Software Development
- 90.1% on AIME and 73.4% on LiveCodeBench with low latency, delivering near-instant deductive code solutions.
- 56.8% on SWE-bench Verified, outpacing older frontier models like o1 at 1/10th the token cost.
- Refined tool-use mechanics enable zero-latency multi-turn agent conversations and automated test suites.
- Highly cost-effective ($1.20/M input, $4.80/M output) for parallel subagent swarms.
Swarm Multi-Agent Topology
Best Paired With: Claude 3.7 Sonnet as Lead Planner
Combines reasoning depth with rapid execution, making it the premier subagent for complex algorithmic implementation jobs in Task Programs.
Executes parallel unit test generation and validation across multiple sibling worktrees.
What Developers & Practitioners Are Saying
Real-world field observations, production strengths, and developer consensus
"Next-generation compact reasoning powerhouse, further compressing the cost and latency of o3-tier deduction for high-concurrency subagents."
Verified Real-World Strengths
- 56.8% on SWE-bench Verified at lightweight cost ($1.20/M input)
- Ultra-fast reasoning output
- Refined JSON schema adherence and structured tool calling
Production Caveats & Gaps
- Less broad domain breadth than full o3 on obscure academic papers
- Requires explicit prompts to balance concise vs detailed responses
