Best daily driver for coding and writing — the model most developers actually reach for.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You specifically need desktop-control capabilities (GPT-5.4) or the absolute highest coding ceiling (Opus 4.6).
The fastest way to see where the recommendation shifts when your priority changes.
58.6% on SWE-Bench Pro, ahead of GPT-5.4 on the same public coding benchmark
82.7% on Terminal-Bench 2.0 for complex command-line workflows
1M token API context window for large-codebase and document-heavy workflows
Claude Opus 4.7 leads GPT-5.5 on SWE-Bench Pro for pure coding ceiling
Premium API pricing makes it less attractive for high-volume low-risk work
