Model Card

Agnes 2.0 Flash is a chat model from Sapiens AI, built for high-frequency production use such as agent workflows, tool calling, coding, multi-turn conversations, reasoning, and image understanding.

Sapiens AI reports a Pass^3 score of 60.9% on Claw-Eval, a benchmark for autonomous agents, placing Agnes 2.0 Flash among the top 10 models on the benchmark's general leaderboard alongside labs including Anthropic, OpenAI, and Google. The model supports tool calling, streaming responses, image URL inputs, and a thinking mode for harder requests.

Agnes 2.0 Flash is offered at no cost for both input and output tokens, part of Sapiens AI's push to keep its models free indefinitely with no waitlist. That makes it worth trying for agentic or tool-using applications that need to run frequent API calls without per-token charges, though its 65.5K token output cap is smaller than Agnes 1.5 Pro's.
