gemini-3.1-pro-preview

gemini-3.1-pro-preview is a preview model entry for Gemini 3.1 Pro, suitable for evaluating complex reasoning, long material synthesis, and advanced code collaboration capabilities in a controlled environment. It can be used for problem analysis prototyping, cross-document research assistants, complex plan generation, code reviews, and multi-step tool orchestration. When using it, the source of facts, calculation rules, and tools allowed to be called should be clearly written, and the effect should be tested with task success rate and manual scoring. As it is still in the preview phase, interface behavior, availability and performance may change, requiring alternatives for critical production processes.

  • gpt-5.2

    gpt-5.2 是 OpenAI 的上一代专业工作旗舰模型。官方目录将它描述为支持可配置推理强度的模型,适合需要较强分析、代码、文档处理和工具调用能力的工作流。它可用于复杂客服升级、业务研究、代码审查、结构化提取和多步骤任务执行。设计请求时应明确是否启用推理、输出格式及工具权限,并用固定测试集衡量迁移后的质量差异。对于关键结论,应结合检索来源、业务校验规则和人工复核,而不是仅凭生成结果做决策。

  • kimi-k2.6

    kimi-k2.6 是 Moonshot AI 的 Kimi 系列模型标识,Kimi 系列文本模型版本。它可用于长文档梳理、研究资料问答、代码协作、写作辅助和企业知识检索。实际可用的上下文长度、工具能力、缓存与计费方式应以 Moonshot 或接入云平台的官方模型页为准。使用时应把任务目标、文档范围、引用格式和输出结构写清楚;对合同、财务、医疗等需要高准确性的内容,应保留原文定位、来源核验和人工审批。
