Anthropic: Claude Opus 4
This AI model is called Claude Opus 4, developed by Anthropic. It can handle various types of input, including images, text, and files, with a context length of up to 200,000 tokens. Additionally, it supports tools and reasoning capabilities, but does not provide structured output. For users who need to process large volumes of data, Claude Opus 4 is worth considering due to its ability to handle various input modalities. Its price point of $15.0/M input token may be competitive for those with large datasets. However, the model's blended benchmark score of 68.0 across three independent benchmarks indicates that it may not be the top choice in terms of performance, especially at an output cost of $75.0/M tokens.
