About DeepSeek V4.1 Flash 1017

DeepSeek-V4.1-Flash-1017 is the latest iteration of V4.1-Flash, trained with self-feedback-based reinforcement learning to deliver substantial gains over its predecessor across benchmarks such as Terminal-Bench 4.0, DeepSWE v1.1, and ProgramBench, while shortening task runtime and output length to reach a new performance–cost Pareto optimum across multiple harnesses. Its ability to build complete projects from scratch is further strengthened, enabling "wish-based" programming tasks such as game development and 3D modeling, while retaining the same 552B-parameter MoE, native multimodal visual understanding, 1M-token context window, and 384K-token maximum output.

DeepSeek V4.1 Flash 1017 is a chat model by DeepSeek, available on Eden AI through 5 endpoints from 5 providers, from $0.098 per million input tokens and $0.39 per million output tokens, with a context window of up to 1.05M tokens.
