Claude Opus 5 (Fast)
Claude Opus 5 from Anthropic is designed to handle text, images, and files with a context length of up to one million tokens; it supports reasoning and can interface with external tools. While it excels in versatility and analytical capabilities, its lack of structured output limits some use cases. Given its high input cost at $10 per million tokens for inputs and $50 for outputs, Claude Opus 5 is best suited for organizations willing to invest significant resources or those needing advanced multimodal processing with reasoning support. Currently, there are no independent benchmarks to compare its performance against other models.
