Perplexity CEO Aravind Srinivas 宣布开源其 Decision Models，称这类模型能处理数十亿 token 的遥测数据、发现安全问题并以新的规模和成本结构帮助修补漏洞，模型已在 OpenRouter 上免费开放一周。引用内容提到内部一天内读取 1B tokens、覆盖 7,000 个 agent 会话并促成 14 项安全规则修复，两个模型采用 Apache 许可、11 月 19 日前在 OpenRouter 免费。
Decision Models are the future of agentic security. They can process billions of tokens of telemetry, identify security issues, and help you patch fixes at a scale and cost structure not possible before. We’ve open sourced our models and made it free on Openrouter for a week.
