Strengths & weaknesses
ChatGPT (GPT-6 Astra / GPT-6 Sol)
OpenAI's GPT-6 Astra launched September 3–8, 2026 as the new flagship: stronger agentic work with 1.05M-token context, 128K output tokens, and a $10/M input, $50/M output API rate matching Fable 5.1. GPT-6 Sol and GPT-6 Luna launched September 22, 2026, succeeding GPT-5.6 Sol/Terra/Luna as OpenAI's mainline mid-tier and free-tier models (GPT-5.6 Sol/Terra/Luna are still listed in OpenAI's API; GPT-5.6 Cyber is a separate cybersecurity model). GPT-6.1 Sol (September 29, 2026; $2/M input, $10/M output, also in OpenAI's API as gpt-6.1-sol) is in ChatGPT Work and Codex on paid plans (Plus, Pro, Business, Enterprise, Edu), not yet in Chat and not on Free or Go. ChatGPT Images 2.5 launched September 8 with a Sketch feature (drawing-to-image) and 50% faster generation. GPT-Live-1 API and the Agents API launched September 10. ChatGPT for Financial Services (Morgan Stanley, Evercore) also launched September 10. Used by over half of all chatbot users worldwide.

Which should you choose?
Choose ChatGPT if…
You want one tool that does everything (agents, research, image generation, and voice) with the most polished apps and integrations. Best default for general use and beginners.
Choose Claude if…
Your work is mostly coding or serious writing. Claude leads on code quality and long-form writing, with excellent long-context retention.
Choose Gemini if…
You live in Gmail, Docs and Drive, work with very large documents, or want frontier quality at the lowest price. Best native multimodality of the three.

ChatGPT vs Claude vs Gemini: which is best in 2026?▾
There is no single winner; it depends on the task. ChatGPT (GPT-6 Astra / GPT-6 Sol) is the best all-rounder with the broadest feature ecosystem. Claude (Fable 5.1 / Opus 5.5) leads on coding and long-form writing quality. Gemini 3.1 Pro is strongest for research, huge documents, and Google Workspace users. Most power users keep two of the three.
Is Claude better than ChatGPT?▾
For coding and careful long-form writing, most reviewers give the edge to Claude (Opus 5.5, with Fable 5.1 for frontier agentic coding). For a broad ecosystem (agents, image generation, voice, and the largest app selection), ChatGPT (GPT-6 Sol) is ahead. If your work is mostly code or writing, Claude; if you want one tool that does a bit of everything, ChatGPT.
Is Gemini better than ChatGPT?▾
Gemini 3.1 Pro wins on context window size, native multimodality, and Google Workspace integration, and it is the cheapest path to a frontier model (from $7.99/mo). ChatGPT wins on ecosystem breadth and polish. Choose Gemini if you live in Gmail/Docs or work with very large documents; choose ChatGPT for general-purpose use.
Which is cheapest?▾
Gemini has the lowest paid entry point (AI Plus at $7.99/mo), and ChatGPT added an $8/mo Go tier. All three offer a free tier. For frontier-level quality, Claude and ChatGPT start at $20/mo; Gemini's mid tier is $19.99/mo.
Do I need all three?▾
