In October 2025, the tech landscape was abuzz with activity. At the end of September, DeepSeek launched the DeepSeek-V3.2-Exp model, which introduced the DSA (Dynamic Sparse Attention) sparse attention mechanism. This innovation optimized CUDA operators, boosted long-text processing and reasoning efficiency, and notably slashed API prices. Anthropic swiftly followed suit by unveiling Claude Sonnet 4.5, touted as the world's premier coding model. It boasts robust engineering implementation capabilities and the ability to handle long-duration tasks. Alongside this release, Anthropic rolled out multiple product feature updates. In a parallel move, Google fully integrated its Gemini large language model into the Chrome browser, reshaping the very paradigm of browser usage. Adding to the tech frenzy, NVIDIA disclosed its acquisition of a stake in OpenAI and its collaboration in constructing a super data center to bolster the development of the next generation of super-intelligent models.
