Best premium model for coding agents and high-stakes engineering work.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You need cheaper high-volume throughput, image generation, or a workflow that must stay inside OpenAI tooling.
The fastest way to see where the recommendation shifts when your priority changes.
64.3% on SWE-Bench Pro, ahead of GPT-5.5 and GPT-5.4 in current public comparisons
1M context window for large codebases and document-heavy workflows
Strong vision and agentic consistency improvements over Opus 4.6
Premium pricing is expensive for high-volume workloads
GPT-5.5 has stronger OpenAI ecosystem fit and faster Codex availability for some teams
