Capability scores are out of 100 and reflect our own weighting of published benchmarks and production signals — see how we evaluate models. “Est. month” assumes 10M input and 2M output tokens at list price, with no batch or caching discounts applied, so treat it as a ceiling.
What each one is genuinely good at, where it falls down, and the situations we would steer you away from it — not just the headline score.
Google's fastest-moving coding workhorse — 80.8% on SWE-bench Verified at half the price of Gemini 3.6 Flash, shipped just three weeks after it.
You are planning 2027 spend and need price certainty — the introductory rate expires December 31, 2026.
The best coding score per dollar in Google's lineup right now — 80.8% SWE-bench Verified at $0.75/1M input. Budget on the post-January 2027 price of $1.50/$7.50 if you are signing anything long-term.
Released August 13, 2026, only three weeks after Gemini 3.6 Flash. Introductory pricing of $0.75/$3.75 runs through December 31, 2026; on January 1, 2027 it doubles to $1.50/$7.50, which is exactly Gemini 3.6 Flash's rate.
Anthropic's most agentic Sonnet yet — a fast 1M-context workhorse that narrows the gap to Opus-class quality at $3/$15, and the new default model on claude.ai.
You need the absolute top coding ceiling — Opus 5 leads SWE-bench Verified by over 20 points.
The best price-to-capability pick in the Claude lineup. Sonnet 5 replaces Sonnet 4.6 as the production default: markedly better agentic coding and computer use at the same standard price, with a $2/$10 promo through August 2026.
Released June 30, 2026. Default model for Free and Pro claude.ai plans. Promo pricing $2/$10 per 1M through Aug 31, 2026, then $3/$15. 128K max output, Jan 2026 knowledge cutoff.

Gemini 3.7 Flash wins on more of the categories we score — coding, reasoning, long context — so it is the better default of the two. Claude Sonnet 5 is the better pick when your work is mostly high-volume agentic workloads and production apps at mid-tier pricing. Neither is universally "better": Gemini 3.7 Flash is aimed at high-volume coding and long-context work at introductory Flash pricing, Claude Sonnet 5 at high-volume agentic workloads and production apps at mid-tier pricing.
Gemini 3.7 Flash is cheaper at $0.75/1M input and $3.75/1M output. Claude Sonnet 5 costs $3/1M input and $15/1M output.
Gemini 3.7 Flash has the larger context window at 1.048576M tokens vs Claude Sonnet 5's 1M. For large document analysis, Gemini 3.7 Flash is the stronger pick.
Claude Sonnet 5 is better for coding with a score of 98 vs Gemini 3.7 Flash's 89 (out of 100). Claude Fable 5 is the overall coding leader in this directory at 100/100.
Both Gemini 3.7 Flash and Claude Sonnet 5 have similar speed profiles — rated fast. Neither will be the bottleneck if latency is your deciding factor.
The $0.75/$3.75 launch price is introductory — it doubles to $1.50/$7.50 on January 1, 2027. Still short of Claude Opus 5 (96%) and GPT-5.6 Sol (96.2%) on SWE-bench Verified for the hardest coding work. Avoid it if you are planning 2027 spend and need price certainty — the introductory rate expires December 31, 2026. That is the main case for looking at Claude Sonnet 5 instead.
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. Against Gemini 3.7 Flash specifically, the gap shows up most on coding (89 vs 98).
Take a moderate workload of 10M input and 2M output tokens a month. Gemini 3.7 Flash runs $15.00 (at $0.75/1M in and $3.75/1M out); Claude Sonnet 5 runs $60.00 (at $3/1M in and $15/1M out). That is a $45.00/month difference — Gemini 3.7 Flash 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 Gemini 3.7 Flash for high-volume coding and long-context work at introductory Flash pricing, with Claude Sonnet 5 handling high-volume agentic workloads and production apps at mid-tier pricing. Since Gemini 3.7 Flash is both the stronger and the cheaper option here, a split mainly makes sense if Claude Sonnet 5 covers a capability you specifically need.
