Deepseek V4.1 Flash 1017 beats larger rivals in agentic tasks while once again massively cutting per-task costs

Training a model usually needs human graders or a second model to score its answers. DeepSeek says its new Flash model scores its own attempts instead, using its confidence estimates and self-written critiques as the reward signal, which the company says shortens answers and cuts cost. On its coding tests it solved 77% of tasks for under $0.20 each, and the weights are free to download.
