DeepSeek's New AI Is An Absolute Monster
Summary
DeepSeek has released a new AI system, DeepSeek v4.1 Flash 1017, demonstrating significant improvements in generating working software and operating via the terminal. While the version number increment is minor, the core innovation is attributed to the model's ability to learn from self-feedback, allowing it to critique and improve its own work, similar to human learning. The model is available via API for a low cost (claimed 15 times cheaper than Claude Opus 5.5), and its weights can be downloaded for free, promoting open-source alternatives in the AI space.
