  "account": "Gemini Decisions API is a new technology that generates decisions and enters the decision model field with Gemini Decision 1. It competes with other similar products from Jev and OpenAI. Unlike open-ended text generation, Gemini Decision 1 focuses on three types of structured decision tasks: yes/no judgment, option selection, and scoring based on a given criterion.\n\nSimilar to Jev, Gemini Decision 1 uses \"Noul\" to name yes/no problems. For engineers concerned with model interfaces and engineering applications, this API is notable for its input modality, calling costs, and whether the returned results are discrete decisions or probability values. Pricing for input and supported input modalities are as follows:\n\n* Gemini Decision 1: $0.10 per million tokens, supports text, images, audio, video, PDF\n* OpenAI GPT-6 Luna Decision Model: $0.10 per million tokens, supports text, images\n* Jev: $0.042 per million tokens, supports text, JSON\n\nGemini Decision 1's output is free, and its input price is the same as GPT-6 Luna's Decision Model. Comparing only input price and input form, Jev is the cheapest. However, this comparison does not equate to a complete performance or total cost assessment.\n\nTo test Gemini Decision 1, a video of a mechanical dragon kicking its legs was submitted and four questions were asked: does the video contain a dragon? Is there a robot in the video? Is the scene in France? Is the scene in the United States? The API returned the following results:\n\n{\ndragon : {\ntype : yes_no,\nprobability : 0.04976021841520312\n},\nrobot : {\ntype : yes_no,\nprobability : 0.9234055387792485\n},\nfrance : {\ntype : yes_no,\nprobability : 0.08329171353166241\n},\nusa : {\ntype : yes_no,\nprobability : 0.9230459995157706\n}\n}\n\nAll results are marked as yes_no, but the probability is not a simple 0.0 or 1.0. The conditions returned probability values (rounded), and the video contains a dragon with 5.0% probability, a robot with 92.3% probability, the scene is in France with 8.3% probability, and the scene is in the United States with 92.3% probability. Unlike other interfaces that return 1.0 or 0.0, Gemini Decision 1 returns a number between the two.\n\nThe interpretation of this result shows that Gemini Decision 1's yes/no judgment can return non-binary probability values, not just \"yes\" or \"no.\" However, returning a probability field does not necessarily mean the probability has been well calibrated. For example, 0.923 does not mean the judgment is similar to being correct 92.3% of the time based on this single result. Similarly, the high probability for the United States scene does not mean the location has been independently confirmed. Therefore, this example is suitable for understanding response structure and output format, but evaluating overall accuracy or probability calibration requires more than one test.",
  "summary": "不只生成文本，也能输出决策 Gemini Decisions API 以 Gemini Decision 1 进入决策模型领域，与 Jev 和 OpenAI 的同类产品竞争。它面向的不是开放式文本生成，而是三类结构化决策任务： 是非判断 ：判断某个条件是否成立。 选项选择 ：从给定选项中作出选择。 按标准评分 ：依据指定的评分规则打分。 其设计与 Jev 接近，也沿用了 Jev 对是非问题的称呼“Noul”。 对于关注模型接口与工程应用的 写好标智库 读者，这类 API 值得留意的地方，是输入模态、调用成本，以及返回结果究竟是离散判断还是概率值。 输入价格与模态支持 模型或服务 输入价格（每百万 token） 支持的输入形式 Gemini Decision 1 0.10 美元 文本、图像、音频、视频、PDF OpenAI GPT-6 Luna 决策模型 0.10 美元 文本、图像 Jev…",
