ChatGPT vs Claude
OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.7 are the two most capable closed-source AI models of 2026. Here is a side-by-side breakdown of how they actually differ in practice.
Claude (Opus 4.7)
Anthropic's flagship with hybrid reasoning, adaptive thinking, a 1M-token context window and high-resolution vision support.
| ChatGPT (GPT-5.5) | Claude (Opus 4.7) | |
|---|---|---|
| Latest flagship | GPT-5.5 (Apr 2026) | Claude Opus 4.7 (Apr 2026) |
| Context window | 256K tokens | 1M tokens |
| Max output | 128K tokens | 128K tokens |
| Reasoning style | Direct, low-latency | Adaptive hybrid thinking |
| Vision | Yes | Yes (high-res, up to 3.75 MP) |
| Pricing (output) | OpenAI tiers | $25 / 1M tokens |
| Best at | Agentic coding, computer use | Long-context reasoning, careful analysis |
Pick ChatGPT (GPT-5.5) when you want the fastest flagship for agentic coding, tool use, and high-quality answers without paying for a 1M-token context.
Pick Claude Opus 4.7 when you have very long inputs (legal, finance, research), high-resolution images, or workflows where adaptive thinking effort pays off.
The verdict
Both are state-of-the-art frontier models. GPT-5.5 is the better default for fast agentic coding and product workloads. Claude Opus 4.7 wins for long-context reasoning, vision-heavy work and adaptive thinking depth.
