GPT-5.5 wins on coding (96 vs 85) and writing quality and price ($5 vs $12/1M input) and context window (1M vs 200K). For most workflows, GPT-5.5 is the stronger default — best openai flagship for agentic coding, research, and computer-use work.
The shortest way to see the safest default, the lower-cost option, and the specialist pick before you read deeper.
GPT-5.5 is the safest overall answer here when you want the strongest default instead of the lowest list price.
Meta: Llama 3.1 8B Instruct is the lower-cost option to start with when you still need useful output at scale.
GPT-5.2 is the better pick when response speed matters more than maximum reasoning depth.
GPT-5.5 leads on coding with a score of 96 vs 85 for GPT-5.2.
GPT-5.5 has the larger context window: 1M vs 200K for GPT-5.2.
GPT-5.5 is cheaper at $5/1M input tokens vs $12/1M for GPT-5.2.
Choose GPT-5.5 for coding and research — agentic coding.
Choose GPT-5.2 when serious coding and complex product work.
Both models serve different primary workflows — consider using each where it has a clear edge.
Switch the scoring lens to see whether the top answer changes when you care more about cost, speed, or long-document work.

Best OpenAI flagship for agentic coding, research, and computer-use work.
Ranks models by the broadest mix of coding, writing, research, and long-context usefulness.
You only care about the highest public coding benchmark score or need a cheaper high-volume model.
The fastest way to see where the recommendation shifts when your priority changes.
Best OpenAI flagship for agentic coding, research, and computer-use work.
Capable but outclassed — GPT-5.4 is now cheaper and better.
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
