DeepSeek

DeepSeek is the architect of the 'DeepSeek movement,' a fundamental shift in AI development that prioritizes extreme efficiency over raw compute. Founded by High-Flyer Quant, they proved that architectural innovations like Multi-head Latent Attention (MLA) and DeepSeekMoE could match the performance of $100B models like GPT-4o and Claude 3.5 while costing 95% less to train and run. Their ecosystem includes the flagship DeepSeek-V3, the reasoning-heavy DeepSeek-R1, and the state-of-the-art DeepSeek-VL2 for high-fidelity OCR and vision tasks. DeepSeek is committed to the open-source community,...

DeepSeek-V4.1-Flash is DeepSeek's efficient multimodal model. The line launched September 10, 2026, and the October 17 checkpoint, V4.1-Flash-1017, is the one on the website, the app, the API and Hugging Face. DeepSeek describes a 552-billion-parameter mixture of experts with 8 billion parameters active on input and 16 billion on output, native image understanding, and a context of up to 1 million tokens. Call it as deepseek-flash. The older names deepseek-v4-flash and deepseek-v4-flash-vision-exp route to this model. Weights are under the MIT licence. DeepSeek says the October 17 update...
