OpenAI: GPT-5 Mini Benchmarks & Agentic Accuracy
Verified primary research & developer preference metrics
What This Means in Real Software Development
- Exceptional 54.0% SWE-bench Verified score at 1/6th the cost of frontier flagship models.
- Blazing throughput slashes execution times across multi-agent task programs.
- Scores 76.0% on AIME 2024, handling intricate algorithmic edge cases reliably.
- Ideal engine for parallel Coder subagents running simultaneous test suites.
Swarm Multi-Agent Topology
Best Paired With: Claude 3.7 Sonnet or GPT-5 as Lead Planner
Strong coding benchmarks allow running 4-8 parallel Coder workers across separate worktrees simultaneously.
Executes isolated bug fixes and author tests inside dedicated worktrees without cross-worker contention.
