GPT-5.5 wins on coding (96 vs 85) and writing quality and context window (1M vs 200K). GPT-5.2 wins on price ($1.75 vs $5/1M input). For most workflows, GPT-5.5 is the stronger default — best openai flagship for agentic coding, research, and computer-use work.
The safest GPT-5.5 vs GPT-5.2 default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
GPT-5.5 is the strongest answer here for GPT-5.5 vs GPT-5.2 — pick it when quality of output matters more than the $5.00/1M/1M input you pay for it.
GPT-5.2 handles the same job for about 55% less per token. Start here and only move up if the output is not good enough.
GPT-5.5 is the fastest of these for GPT-5.5 vs GPT-5.2 — worth it when latency is what the reader notices, not the last few points of 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-5.2 is cheaper at $1.75/1M input tokens vs $5/1M for GPT-5.5.
Go with GPT-5.5 if you want one model to handle coding and research — it targets agentic coding, computer-use workflows, and complex research tasks.
Choose GPT-5.2 when your work is mostly serious coding and complex product work — that is the workload it was tuned for.
GPT-5.2 is the more cost-efficient option at $1.75/1M input — GPT-5.5 costs 3x more per input token, so the gap is worth taking seriously wherever token volume rather than peak quality drives the bill.
Switch the scoring lens to see whether the GPT-5.5 vs GPT-5.2 answer changes when cost, speed, or long-document depth leads the decision.

Why each one is on the shortlist for GPT-5.5 vs GPT-5.2, what it is genuinely good at, and where we would steer you away from it.
Our pick for GPT-5.5 vs GPT-5.2. It scores 96/100 on the coding axis we weight this page by, and nothing else in this shortlist matches it on output quality.
OpenAI's latest agentic flagship for coding, research, computer-use workflows, and long multi-step knowledge work.
You only care about the highest public coding benchmark score or need a cheaper high-volume model.
The strongest OpenAI pick for agentic coding and knowledge work. Claude Opus 4.7 still wins on the public SWE-Bench Pro coding number, but GPT-5.5 is the better OpenAI default when ecosystem, Codex, or computer-use workflows matter.

The cost-conscious pick for GPT-5.5 vs GPT-5.2, about 55% less per token than GPT-5.5 than the top choice while holding 85/100 on coding.
Reliable OpenAI flagship for serious coding and product work — a strong default before GPT-5.4 was released.
You're starting a new project — GPT-5.4 is cheaper and more capable.
Still capable but GPT-5.4 at $2.50/1M input is now cheaper and better. Hard to justify GPT-5.2 at $12/1M for new projects.

GPT-5.5 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. GPT-5.2 is the better pick when your work is mostly serious coding and complex product work. Neither is universally "better": GPT-5.5 is aimed at agentic coding and computer-use workflows, GPT-5.2 at serious coding and complex product work.
GPT-5.2 is cheaper at $1.75/1M input and $14/1M output. GPT-5.5 costs $5/1M input and $30/1M output.
GPT-5.5 has the larger context window at 1M tokens vs GPT-5.2's 200K. For large document analysis, GPT-5.5 is the stronger pick.
GPT-5.5 is better for coding with a score of 96 vs GPT-5.2's 85 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
Both GPT-5.5 and GPT-5.2 have similar speed profiles — rated balanced. Neither will be the bottleneck if latency is your deciding factor.
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. Avoid it if you only care about the highest public coding benchmark score or need a cheaper high-volume model. That is the main case for looking at GPT-5.2 instead.
Superseded by GPT-5.4 for most use cases. Claude Sonnet 4.6 leads on both coding and writing quality. Avoid it if you're starting a new project — GPT-5.4 is cheaper and more capable. Against GPT-5.5 specifically, the gap shows up most on coding (96 vs 85).
Take a moderate workload of 10M input and 2M output tokens a month. GPT-5.5 runs $110.00 (at $5/1M in and $30/1M out); GPT-5.2 runs $45.50 (at $1.75/1M in and $14/1M out). That is a $64.50/month difference — GPT-5.2 is the cheaper of the two at this volume, and the gap scales linearly as you send more. Output tokens dominate the bill on both, so prompt length matters far less than response length.
Yes, and for most teams that beats picking one. A common split is GPT-5.5 for agentic coding and computer-use workflows, with GPT-5.2 handling serious coding and complex product work. Routing high-volume, low-stakes calls to GPT-5.2 at $1.75/1M and reserving GPT-5.5 for the hard cases is usually the cheapest arrangement that does not cost you quality.
