ChatGPT vs Claude vs Gemini
The three dominant AI assistants each have distinct strengths. We compare GPT-5.5, Claude Opus 4.7, and Gemini 3.1 Pro across reasoning, coding, writing, context window, and pricing.
| Feature | ChatGPT | Claude | Gemini |
|---|---|---|---|
| Latest Model | GPT-5.5 (released Apr 23, 2026) — most capable OpenAI model yet. | Claude Opus 4.7 / Sonnet 4.6 — best for long documents and coding. | Gemini 3.1 Pro (released Mar 3, 2026) — best Google integration and multimodal. |
| Context Window | GPT-5.5: context window not yet officially confirmed. | 200K tokens (Sonnet 4.6) · 1M tokens (Opus 4.6+). | 2M tokens (Gemini 3.1 Pro) — largest context window available. |
| Coding Ability | Excellent — GPT-5.5 best agentic coding. GitHub Copilot powered by GPT. | Excellent — Claude 4 best for large codebase refactors. | Very good — strong with Google stack (Firebase, Android, Cloud). |
| Writing Quality | Very good — versatile tone, broad training data. | Best overall — nuanced, structured, least AI-sounding output. | Good — slightly more factual/neutral tone. |
| Reasoning | GPT-5.5 is top-tier — strongest agentic and knowledge work. | Strong extended thinking on Opus. Best for document analysis. | Strong — Gemini 3.1 Pro scores 77.1% on ARC-AGI-2. |
| Free Tier | GPT-5.5 on ChatGPT Plus/Pro. GPT-4o mini free unlimited. | Claude.ai free tier with Claude Sonnet. Limited daily messages. | Gemini free in Google apps. Gemini 3.1 Pro free with limits in AI Studio. |
| Paid Price | ChatGPT Plus: $20/mo · Pro: $200/mo (GPT-5.5 Pro access). | Claude Pro: $20/mo. API: $3–$75 per 1M tokens. | Google One AI Premium: $20/mo. API: $2.00/$12.00 per 1M tokens. |
| Best For | General use, agentic tasks, image generation (DALL-E), plugins. | Long documents, coding, nuanced writing, enterprise safety. | Google Workspace users, very long context (2M), multimodal tasks. |
ChatGPT Pros & Cons
Pros
- GPT-5.5 is most capable OpenAI model — best agentic coding
- Largest ecosystem — plugins, GPTs, integrations everywhere
- DALL-E image generation built in
- Best for non-technical users — widest adoption
Cons
- GPT-5.5 pricing higher than predecessors
- Context window not officially confirmed for GPT-5.5
- Can be verbose and sycophantic
Claude Pros & Cons
Pros
- Best writing quality — least robotic output
- Up to 1M token context window on Opus
- Strongest safety and harmlessness focus
- Extended thinking (Opus) best for complex reasoning tasks
Cons
- No image generation built in
- Less integrated into third-party apps than ChatGPT
- Opus is expensive on API ($75/M output tokens)
Verdict
GPT-5.5 is OpenAI's most powerful model yet — best for agentic coding, computer use, and knowledge work. Claude wins for developers and writers who need the highest quality output, long document analysis, or large codebase work. Gemini 3.1 Pro is the best choice if you live in Google Workspace or need a massive 2M token context window. All three offer $20/mo plans — try each on your actual use case before committing.
