Anthropic 发布 Claude Haiku 5.5,定价对标 GPT-6 Luna
Anthropic 发布 Claude Haiku 5.5,这是 Haiku 系列约一年来的首次更新,定价与 OpenAI 的 GPT-6 Luna 持平,同日还下调了 Sonnet 5.5 与订阅方案价格。Artificial Analysis 的独立评测显示其 Intelligence Index 为 43(最高 effort),比上一代 Haiku 提升 26 分,略高于 GLM-5.3 Flash(42)、Gemini 3.8 Flash(41)和 GPT-6 Luna(38),但落后 Claude Sonnet 5.5(56)13 分。该模型支持 1M token 上下文(Haiku 4.5 为 200k),首次引入 effort 设置与自适应思考,主要代价是 token 消耗偏高,最高 effort 下每个 Index 任务约用 162k 输出 token,约为 GPT-6 Luna 的 3 倍。
