GPT-5.4-Mini Benchmarks & Agentic Accuracy
Verified primary research & developer preference metrics
What This Means in Real Software Development
- Breaks the 60% barrier on SWE-bench Verified (61.2%) for a lightweight, sub-dollar model.
- High throughput ensures rapid test authoring, code compilation, and error recovery.
- Strong 88.0% on AIME demonstrates deep logic for competitive algorithms and data structures.
- The ideal model for running 5+ concurrent Coder subagents in Swarm.
Swarm Multi-Agent Topology
Best Paired With: Claude 3.7 Sonnet as Lead Planner
High throughput and low pricing make it the premier engine for concurrent Coder and Finder jobs.
Executes parallel bug fixes across isolated worktrees without file contention.
What Developers & Practitioners Are Saying
