Context Windows: A Shared Advantage
You may hear OpenAI and Anthropic gloat about their ‘context window’ sizes. This, plainly, is the amount of text an AI can process in a single conversation.
This was once a major differentiator, but that gap has closed significantly in 2026. Both platforms now support up to 1 million tokens (approximately 750,000 words, or roughly 2,000 pages of text!)
ChatGPT (GPT-5.4):
- Standard context window: 272,000 tokens
- Extended context: up to 1 million tokens in Codex and API (with 2x pricing above a certain limit)
- 400,000 token context window on GPT-5.4 Mini
Claude (4.6 Family):
- Claude Opus 4.6: 1 million tokens (for all plans at standard pricing)
- Claude Sonnet 4.6: 1 million tokens (at standard pricing)
- Supports up to 600 images or PDF pages per request
What this means in practice is that both platforms can now analyze entire books, review comprehensive codebases, maintain context across very long conversations, and process multiple files simultaneously. Claude's 1M context is generally available at standard pricing with no surcharge, while ChatGPT's 1M context is currently available in Codex and API contexts at premium rates.
