How they differ
Context handling
Claude Opus 4.7
Claude Opus 4.7 supports a token context of up to 1,000,000, enabling extensive information processing.
o1
o1 supports a smaller token context of up to 200,000, suitable for more constrained input sizes.
Cost profile
Claude Opus 4.7
Claude Opus 4.7 offers a lower cost structure at $5.0 per 1M input tokens and $25.0 per 1M output tokens.
o1
o1 has a higher cost structure, charging $15.0 per 1M input tokens and $60.0 per 1M output tokens.
Vision
Claude Opus 4.7
Claude Opus 4.7 supports text and image inputs for multimodal tasks.
o1
o1 expands multimodal capabilities to include text, image, and file inputs.
Claude Opus 4.7 — what sets it apart
- +Offers significantly larger token context, suitable for long-form or extensive processing tasks.
- +Designed with cost-efficiency in mind, with lower per-token input and output rates.
o1 — what sets it apart
- +Includes file input capabilities alongside text and image, enabling broader input flexibility.
- +May optimize for task-oriented reasoning through structured API capabilities.
The most consequential difference is Claude Opus 4.7's significantly larger token context size and cost-efficiency, compared to o1's additional input flexibility through file handling.
