An improved version of DeepSeek-V4.1-Flash, with enhanced performance in reasoning, coding, agent tasks, and visual benchmarks. It improves cost efficiency by reducing task execution time and output length, and supports a 1M token context window.

It achieved 42.3 points on Terminal-Bench 4.0 and 77.0 points on DeepSWE v1.1, demonstrating improved agent capabilities compared to previous versions. It also scored highly on visual benchmarks such as Chartography and BabyVision, enabling multimodal processing.

It supports FP8 and 8-bit precision to reduce memory usage and is compatible with major inference frameworks such as Transformers, vLLM, and SGLang. Distributed under the MIT license, it can be freely applied to commercial projects.
