Claude Sonnet 5 wins on more of the categories we score — coding, writing, research — so it is the better default of the two. Claude Sonnet 4.6 is the better pick when your work is mostly daily coding and writing. Neither is universally "better": Claude Sonnet 5 is aimed at high-volume agentic workloads and production apps at mid-tier pricing, Claude Sonnet 4.6 at daily coding and writing.
Claude Sonnet 5 is cheaper at $2/1M input and $10/1M output. Claude Sonnet 4.6 costs $3/1M input and $15/1M output.
Both Claude Sonnet 5 and Claude Sonnet 4.6 have the same 1M context window.
Claude Sonnet 5 is better for coding with a score of 98 vs Claude Sonnet 4.6's 97 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
Claude Sonnet 5 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.
Clearly behind Opus 5 and Fable 5 on the hardest reasoning and long-horizon agent tasks. Updated tokenizer produces ~1.0–1.35x more tokens for the same text, so effective cost runs above sticker price. Avoid it if you need the absolute top coding ceiling — Opus 5 leads SWE-bench Verified by over 20 points. That is the main case for looking at Claude Sonnet 4.6 instead.
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). Against Claude Sonnet 5 specifically, the gap shows up most on coding (98 vs 97).
Take a moderate workload of 10M input and 2M output tokens a month. Claude Sonnet 5 runs $40.00 (at $2/1M in and $10/1M out); Claude Sonnet 4.6 runs $60.00 (at $3/1M in and $15/1M out). That is a $20.00/month difference — Claude Sonnet 5 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 5 for high-volume agentic workloads and production apps at mid-tier pricing, with Claude Sonnet 4.6 handling daily coding and writing. Since Claude Sonnet 5 is both the stronger and the cheaper option here, a split mainly makes sense if Claude Sonnet 4.6 covers a capability you specifically need.
