深入解析AI Agent（人工智能代理）的定义、工作原理、主流应用场景及未来发展方向，助您全面理解这一核心AI技术。
The clearest evidence yet that the AI industry's center of gravity is moving: a benchmark report, an OpenAI executive's warning, and a viral demo all point the same way — harness, not the model, wins.
A number that should reset how you read an AI paper: a research-review firm ran AI agents across all 168 ICML 2026 orals. Of 92 papers with checkable claims, only 8 fully reproduced — 99.2% had errors.
The headline isn't "cheap models are good" — it's that the industry finally has a ruler for the half of the system it never measured. Floatboat's benchmark: $0.175 model tops Claude Opus 4.8 on all five.
For years the agent community has repeated one equation: Model + Harness = Agent. The left half gets measured constantly; the right half — everything around the model — finally has its first real benchmark.
On August 7, OpenAI did something it has never done before: publicly admitted its next frontier model may be too dangerous to ship on the current timeline — slowing Astra over critical cyber risk.
