DeepSeek releases V4.1-Flash-1017 with improved coding performance and lower costs · 1 source tracked

By PulseAugur Editorial · [6 sources] ·

DeepSeek has released an updated version of its V4.1-Flash model, named DeepSeek V4.1-Flash-1017. This new open-source model, available under the MIT license on Hugging Face, claims significant improvements in coding benchmarks and a substantial reduction in cost per task compared to its predecessor. While DeepSeek's reported performance metrics show it outperforming models like Kimi K3 and GPT-5.6 Sol on several benchmarks, it still trails Claude Opus-5 on some tests. The cost-effectiveness of the model is verifiable through its public API pricing, but the performance claims await independent reproduction. AI

IMPACT Sets new SOTA on coding benchmarks; pressures Anthropic to respond.
