A new open-source ai, Kimi K2.6, is reported to have capabilities that surpass those of GPT-5.4 in coding. However, the extent of its abilities and how it compares to other models, such as Claude Opus and DeepSeek V4, is unclear, with some outlets mentioning different versions of Kimi and varying results. The development of Kimi K2.6 is part of a broader effort by tech companies to advance coding ai, with the US and China reportedly increasing their investment in this area.
