Translated data: Recently, Anthropic Corporation abroad launched Claude2, and MoonshotAI in China introduced KimiChat, both new products touting themselves as "long-text AI". Top AI players have conducted real-world tests and found that both Claude2 and KimiChat can quickly summarize and extract information from long text reports exceeding 100,000 words, as well as perform cross-text analysis across multiple documents, significantly enhancing the value of AI assistants in practical work. Although both can handle long texts, Claude2 offers a smoother interactive experience, while KimiChat has a slight advantage in Chinese language processing and support for a larger number of files, making it more suitable for domestic users. As the ability to handle long texts continues to improve, AI assistants will play an increasingly significant role in workflows.
