Kimi K3.1 Pro Highspeed 是 K3.1 Pro 的高速版本,保留同等模型能力、原生视觉理解与 1,048,576 token 上下文。它适合开发者正在等待下一次修改、分析人员需要快速查看研究结果,或应用需要连续执行多个工具步骤的场景。
交互式编程可以按“查看现场、修改、运行、检查”循环推进:提供界面截图、当前代码和验收条件,让模型结合视觉信息完成调整,再用实际运行结果确认。处理研究与金融材料时,可以将表格、报告与图像放进同一任务,要求每个判断对应到证据,涉及计算的部分交给工具复核。
Highspeed 的常规输入、输出和缓存写入单价高于 Pro,缓存命中单价与 Pro 相同。大量固定上下文能否复用,会影响一次完整工作流的实际成本;选择型号时,应结合等待时间、输出量与缓存命中情况比较。
模型始终启用推理,支持 low、high、max 三档 reasoning_effort。速度提升不改变工具执行、数据检查与人工审阅的必要性,也不代表图片或视频生成功能:它理解图像与视频,并以文本、代码和结构化结果参与后续制作。
“根据当前页面截图和组件源码,修复移动端表格溢出。先确认触发条件,再提交最小修改,运行相关检查,并用新的页面截图验证 320px 宽度下的滚动和点击行为。”
把每轮目标控制在可检查的范围,让工具返回真实页面与测试结果。下一轮完整保留 assistant 消息、reasoning_content 和工具输出,避免工作状态丢失。
使用 /v1/chat/completions,将 model 设为 kimi-k3.1-pro-highspeed。参数规则与 Pro 相同:reasoning_effort 支持 low、high、max,默认 max;始终开启推理,不使用旧版 thinking 开关。建议省略 temperature、top_p、n 和 penalty 参数。
max_completion_tokens 默认 131,072,参数上限 1,048,576,输入与输出需要满足整体上下文预算。简单交互可以先降低推理强度和输出上限,再评估响应质量。流式请求开启 stream_options.include_usage 后,可读取最终用量明细。
视觉输入建议使用 base64 图像;需要 JSON 结果时使用严格 json_schema,只读取最终 message.content。把稳定资料放在请求前缀,避免在前部插入时间戳或随机值,以便复用缓存。
在同一组真实任务上比较 Pro 与 Highspeed 的耗时、输出用量和缓存命中,再决定默认型号。高速版本的实际响应时间仍受上下文长度、推理强度、工具执行和上游负载影响。

Replace <YOUR_API_KEY> with the API key from your token settings.
All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.
Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.
