Per ValsAI's index, DeepSeek V4.1 Flash is the new #1 open-weight model, beating Kimi K3 while costing just $0.30 per test — the cheapest model in the open-weight top 10.
teortaxesTex adds that V4.1 shows the smallest gap between skills and no-skills runs; unlike V4 GA, which benefited heavily from skills access, V4.1 isn't harness-reliant and is arguably better suited to minimal harnesses.
