Claude Sonnet 4.6 wins on more of the categories we score — coding, writing, research — so it is the better default of the two. GPT-4o is the better pick when your work is mostly multimodal tasks and image-adjacent workflows. Neither is universally "better": Claude Sonnet 4.6 is aimed at daily coding and writing, GPT-4o at multimodal tasks and image-adjacent workflows.
GPT-4o is cheaper at $2.5/1M input and $10/1M output. Claude Sonnet 4.6 costs $3/1M input and $15/1M output.
Claude Sonnet 4.6 has the larger context window at 1M tokens vs GPT-4o's 128K. For large document analysis, Claude Sonnet 4.6 is the stronger pick.
Claude Sonnet 4.6 is better for coding with a score of 97 vs GPT-4o's 58 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
GPT-4o is faster with a fast speed rating (score: 4) vs Claude Sonnet 4.6's balanced rating (score: 3). Speed matters most for interactive and high-throughput work; for batch jobs the Claude Sonnet 4.6 latency penalty is usually invisible.
Claude Opus 4.7 has a higher current premium coding ceiling. GPT-5.5 or GPT-5.4 are better picks when OpenAI computer-use workflows are the priority. Avoid it if you specifically need desktop-control capabilities (GPT-5.5/GPT-5.4) or the absolute highest coding ceiling (Opus 4.7). That is the main case for looking at GPT-4o instead.
Outclassed by newer models on pure coding and reasoning. Gemini 3.1 Pro now handles multimodal at a lower price. Avoid it if you need the latest reasoning or coding performance — GPT-5.4 replaces it for serious work. Against Claude Sonnet 4.6 specifically, the gap shows up most on coding (97 vs 58).
Take a moderate workload of 10M input and 2M output tokens a month. GPT-4o runs $45.00 (at $2.5/1M in and $10/1M out); Claude Sonnet 4.6 runs $60.00 (at $3/1M in and $15/1M out). That is a $15.00/month difference — GPT-4o 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 Claude Sonnet 4.6 for daily coding and writing, with GPT-4o handling multimodal tasks and image-adjacent workflows. Routing high-volume, low-stakes calls to GPT-4o at $2.5/1M and reserving Claude Sonnet 4.6 for the hard cases is usually the cheapest arrangement that does not cost you quality.
