Claude Opus 5
Claude Opus 5, developed by Anthropic, boasts an impressive context length of 1 million tokens and supports various input modalities including text, images, and files. It also features robust tools and reasoning capabilities, making it versatile for complex tasks. However, this model does not offer structured output or open weights, limiting its utility in certain scenarios. Given its high price at $5.0 per million input tokens and $25.0 per million output tokens, Claude Opus 5 is more suitable for organizations willing to invest in a flexible AI tool with broad capabilities. While it currently lacks independent benchmark coverage, its robust modalities and reasoning tools set it apart as a strong contender in the market.
