In October 2026 the three families are closer than ever, and each leads somewhere different. Claude leads coding and writing: Claude Opus 5.5 posts 89.9% on SWE-bench Pro in Anthropic's table, and Claude Sonnet 5.5 is the strongest everyday writer at $2/$10. GPT leads computer use and frontier maths with GPT-6 Astra, and GPT-6.1 Sol is the best value for general reasoning at $2/$10. Gemini leads on speed and multimodal input: Gemini 3.8 Flash is among the fastest capable models and reads video natively.
The safest GPT vs Claude vs Gemini default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
Claude Sonnet 5.5 is the strongest answer here for GPT vs Claude vs Gemini — pick it when quality of output matters more than the $2.00/1M/1M input you pay for it.
Gemini 3.8 Flash handles the same job for about 63% less per token. Start here and only move up if the output is not good enough.
GPT-6.1 Sol is the fastest of these for GPT vs Claude vs Gemini — worth it when latency is what the reader notices, not the last few points of reasoning depth.
Choose Claude when coding quality or writing polish leads the decision.
Choose GPT when you want strong general reasoning, computer use or the OpenAI ecosystem.
Choose Gemini when speed, video or image input, or Google Workspace integration matter most.
Teams that need one premium default for coding and writing should start with Claude Sonnet 5.5.
Teams already built on OpenAI, or doing computer-use automation, should start with GPT-6.1 Sol.
Teams that live in Google tools or process a lot of video and images should start with Gemini 3.8 Flash.
Switch the scoring lens to see whether the GPT vs Claude vs Gemini answer changes when cost, speed, or long-document depth leads the decision.

Scores out of 100 — how we evaluate models. “Est. month” is 10M in / 2M out at list price: a ceiling, no discounts.
Why each one is on the shortlist for GPT vs Claude vs Gemini, what it is genuinely good at, and where we would steer you away from it.
The default answer for GPT vs Claude vs Gemini — 98/100 on the coding axis, and the model we would start with unless the price below rules it out.
Anthropic's September 28, 2026 Sonnet — built for well-scoped everyday work like features, bug fixes, documents, slides and spreadsheets, priced at $2/$10 and close to Opus 5.5 on most of Anthropic's launch rows.
The work is long, ambiguous and multi-step — Anthropic positions Opus 5.5 for exactly that — or you need the lowest possible price, where Haiku 5.5 costs a twentieth as much.
The model most people should default to in the Claude lineup. Sonnet 5.5 lands within a few points of Opus 5.5 on most of Anthropic's launch rows, beats it on Terminal-Bench 4.0, and costs half as much. Step up to Opus 5.5 only when the task is open-ended and long.

Here for latency: it answers fastest of anything listed for GPT vs Claude vs Gemini, at 98/100 on coding.
OpenAI's September 29, 2026 DevDay release — a Sol-tier reasoning model that OpenAI says comes close to GPT-6 Astra on agentic coding, computer use and professional work at one fifth of Astra's price.
You need it inside ordinary ChatGPT chats today, or your prompts regularly pass 272K tokens where the rate doubles.
OpenAI's best value for serious work. GPT-6.1 Sol replaces both GPT-6 Sol and, for most teams, GPT-6 Astra: independent testing has it a point behind Astra at a fifth of the list price. Pick Astra only when the last point of capability is worth five times the bill.
