一、概述
注意:TokenHub 当前上线的所有 MiMo 模型,该模型默认开启深度思考。若在多轮工具调用场景中开启思考模式,建议完整回传历史 reasoning_content 以保持最佳效果;TokenHub 侧缺失该字段不会报错,但可能影响模型表现,详见这篇 多轮工具调用回传 reasoning_content。
二、支持的模型
TokenHub 当前支持以下 MiMo 模型(具体以 模型列表 为准):
| 模型 ID | 类型 | 思考能力 | 上下文窗口 | 最大输入 | 最大输出 |
| mimo-v2.6-pro | 通用全模态模型(文本输入、图片输入、视频输入 / 文本输出) | 支持(默认开启,可关闭) | 1M | 1M | 128K |
| mimo-v2.6-flash | 通用全模态模型(文本输入、图片输入、视频输入 / 文本输出) | 支持(默认开启,可关闭) | 1M | 1M | 128K |
| mimo-v2.5-pro | 通用对话模型(文本输入 / 文本输出) | 支持(默认开启,可关闭) | 1M | 1M | 128K |
模型主要能力:深度思考、Function Calling、结构化输出、Cache 缓存、流式输出。
MiMo 模型对三种协议的支持情况请参见 语言模型调用概览。

七、基础对话
发送单轮对话请求,获取模型回复。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/chat/completions \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "messages": [ {"role": "user", "content": "介绍一下大语言模型"} ], "max_tokens": 2048 }'from openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)response = client.chat.completions.create( model="mimo-v2.5-pro", messages=[ {"role": "user", "content": "介绍一下大语言模型"} ], max_tokens=2048,)print(response.choices[0].message.content)import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const response = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: [ { role: "user", content: "介绍一下大语言模型" } ], max_tokens: 2048,});console.log(response.choices[0].message.content);import okhttp3.*;import org.json.*;OkHttpClient httpClient = new OkHttpClient();JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("max_tokens", 2048);body.put("messages", new JSONArray() .put(new JSONObject().put("role", "user").put("content", "介绍一下大语言模型")));Request request = new Request.Builder() .url("https://tokenhub.tencentmaas.com/v1/chat/completions") .addHeader("Authorization", "Bearer YOUR_API_KEY") .addHeader("Content-Type", "application/json") .post(RequestBody.create(body.toString(), MediaType.get("application/json"))) .build();try (Response response = httpClient.newCall(request).execute()) { JSONObject result = new JSONObject(response.body().string()); System.out.println(result.getJSONArray("choices") .getJSONObject(0).getJSONObject("message").getString("content"));}body := map[string]interface{}{ "model": "mimo-v2.5-pro", "messages": []map[string]string{ {"role": "user", "content": "介绍一下大语言模型"}, }, "max_tokens": 2048,}// … 其余请求代码同快速开始示例
八、流式输出
将 stream 设置为 true 开启 SSE 流式输出。MiMo-V2.5-Pro 默认开启深度思考,响应耗时相对较长,建议长文本或复杂推理场景统一开启流式输出,避免请求超时。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/chat/completions \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "messages": [ {"role": "user", "content": "写一首关于春天的短诗"} ], "max_tokens": 2048, "stream": true }'from openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)stream = client.chat.completions.create( model="mimo-v2.5-pro", messages=[ {"role": "user", "content": "写一首关于春天的短诗"} ], max_tokens=2048, stream=True,)for chunk in stream: if chunk.choices and chunk.choices[0].delta.content: print(chunk.choices[0].delta.content, end="", flush=True)import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const stream = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: [ { role: "user", content: "写一首关于春天的短诗" } ], max_tokens: 2048, stream: true,});for await (const chunk of stream) { const content = chunk.choices[0]?.delta?.content; if (content) process.stdout.write(content);}import okhttp3.*;import okhttp3.sse.*;import org.json.*;OkHttpClient httpClient = new OkHttpClient();JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("max_tokens", 2048);body.put("stream", true);body.put("messages", new JSONArray() .put(new JSONObject().put("role", "user").put("content", "写一首关于春天的短诗")));Request request = new Request.Builder() .url("https://tokenhub.tencentmaas.com/v1/chat/completions") .addHeader("Authorization", "Bearer YOUR_API_KEY") .addHeader("Content-Type", "application/json") .post(RequestBody.create(body.toString(), MediaType.get("application/json"))) .build();EventSources.createFactory(httpClient).newEventSource(request, new EventSourceListener() { @Override public void onEvent(EventSource source, String id, String type, String data) { if ("[DONE]".equals(data)) return; try { JSONObject json = new JSONObject(data); JSONObject delta = json.getJSONArray("choices").getJSONObject(0).getJSONObject("delta"); String content = delta.optString("content", ""); if (!content.isEmpty()) System.out.print(content); } catch (JSONException ignored) {} }});import ( "bufio" "bytes" "encoding/json" "fmt" "net/http" "strings")body := map[string]interface{}{ "model": "mimo-v2.5-pro", "messages": []map[string]string{{"role": "user", "content": "写一首关于春天的短诗"}}, "max_tokens": 2048, "stream": true,}data, _ := json.Marshal(body)req, _ := http.NewRequest("POST", "https://tokenhub.tencentmaas.com/v1/chat/completions", bytes.NewBuffer(data))req.Header.Set("Authorization", "Bearer YOUR_API_KEY")req.Header.Set("Content-Type", "application/json")resp, _ := http.DefaultClient.Do(req)defer resp.Body.Close()scanner := bufio.NewScanner(resp.Body)for scanner.Scan() { line := scanner.Text() if !strings.HasPrefix(line, "data: ") || line == "data: [DONE]" { continue } var chunk map[string]interface{} json.Unmarshal([]byte(strings.TrimPrefix(line, "data: ")), &chunk) choices := chunk["choices"].([]interface{}) delta := choices[0].(map[string]interface{})["delta"].(map[string]interface{}) if content, ok := delta["content"].(string); ok { fmt.Print(content) }}
九、System Prompt
通过 system 角色消息设置模型的行为指令和背景信息。
注意:说明:
注意:建议在 system 消息中注入当前日期(可同时携带身份与角色说明),可提升时间类问题的回答准确度。通用模板如下({date} 与 {week} 替换为实际日期与星期):
注意:你是一位乐于助人的 AI 智能助手。今天的日期:{date} {week}。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/chat/completions \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "messages": [ {"role": "system", "content": "你是一位专业的 Python 编程助手,只回答与 Python 相关的问题,回答简洁明了。"}, {"role": "user", "content": "如何读取一个 CSV 文件?"} ], "max_tokens": 2048 }'from openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)response = client.chat.completions.create( model="mimo-v2.5-pro", messages=[ { "role": "system", "content": "你是一位专业的 Python 编程助手,只回答与 Python 相关的问题,回答简洁明了。", }, {"role": "user", "content": "如何读取一个 CSV 文件?"}, ], max_tokens=2048,)print(response.choices[0].message.content)import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const response = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: [ { role: "system", content: "你是一位专业的 Python 编程助手,只回答与 Python 相关的问题,回答简洁明了。", }, { role: "user", content: "如何读取一个 CSV 文件?" }, ], max_tokens: 2048,});console.log(response.choices[0].message.content);JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("max_tokens", 2048);body.put("messages", new JSONArray() .put(new JSONObject().put("role", "system") .put("content", "你是一位专业的 Python 编程助手,只回答与 Python 相关的问题,回答简洁明了。")) .put(new JSONObject().put("role", "user") .put("content", "如何读取一个 CSV 文件?")));// … 发送请求代码同上body := map[string]interface{}{ "model": "mimo-v2.5-pro", "messages": []map[string]string{ {"role": "system", "content": "你是一位专业的 Python 编程助手,只回答与 Python 相关的问题,回答简洁明了。"}, {"role": "user", "content": "如何读取一个 CSV 文件?"}, }, "max_tokens": 2048,}// … 发送请求代码同快速开始
十、多轮对话
将历史消息一并传入 messages 数组,即可实现上下文记忆的多轮对话。
注意:说明:
注意:纯对话场景(历史消息中不含工具调用)只需回写 content,无需回写 reasoning_content,可有效减少 token 消耗;一旦历史消息中出现过工具调用,则建议完整回传 reasoning_content 以保持最佳效果,详见这篇 多轮工具调用回传 reasoning_content。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/chat/completions \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "messages": [ {"role": "user", "content": "我叫小明,我喜欢打篮球"}, {"role": "assistant", "content": "你好,小明!打篮球是一项很棒的运动。"}, {"role": "user", "content": "你还记得我的名字和爱好吗?"} ], "max_tokens": 2048 }'from openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)# 维护对话历史conversation = [ {"role": "system", "content": "你是一个友好的 AI 助手。"},]def chat(user_input): conversation.append({"role": "user", "content": user_input}) response = client.chat.completions.create( model="mimo-v2.5-pro", messages=conversation, max_tokens=2048, ) reply = response.choices[0].message.content # 纯对话场景只回写 content,不回写 reasoning_content conversation.append({"role": "assistant", "content": reply}) return replyprint(chat("我叫小明,我喜欢打篮球"))print(chat("你还记得我的名字和爱好吗?"))import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const conversation = [ { role: "system", content: "你是一个友好的 AI 助手。" },];async function chat(userInput) { conversation.push({ role: "user", content: userInput }); const response = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: conversation, max_tokens: 2048, }); const reply = response.choices[0].message.content; conversation.push({ role: "assistant", content: reply }); return reply;}console.log(await chat("我叫小明,我喜欢打篮球"));console.log(await chat("你还记得我的名字和爱好吗?"));JSONArray messages = new JSONArray();messages.put(new JSONObject().put("role", "system").put("content", "你是一个友好的 AI 助手。"));messages.put(new JSONObject().put("role", "user").put("content", "我叫小明,我喜欢打篮球"));messages.put(new JSONObject().put("role", "assistant").put("content", "你好,小明!打篮球是一项很棒的运动。"));messages.put(new JSONObject().put("role", "user").put("content", "你还记得我的名字和爱好吗?"));JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("messages", messages);body.put("max_tokens", 2048);// … 发送请求代码同上body := map[string]interface{}{ "model": "mimo-v2.5-pro", "messages": []map[string]string{ {"role": "system", "content": "你是一个友好的 AI 助手。"}, {"role": "user", "content": "我叫小明,我喜欢打篮球"}, {"role": "assistant", "content": "你好,小明!打篮球是一项很棒的运动。"}, {"role": "user", "content": "你还记得我的名字和爱好吗?"}, }, "max_tokens": 2048,}// … 发送请求代码同快速开始
十一、Function Calling(工具调用)
Function Calling 允许模型调用外部工具获取实时数据。模型本身不执行函数,而是返回应调用的函数名和参数,由用户代码执行后将结果传回模型,最终得到自然语言回答。
调用流程:
1. 用户提问 → 模型返回 tool_calls(包含函数名和参数)。
2. 用户代码执行该函数 → 将结果以 role: tool 消息传回。
3. 模型根据函数结果生成最终自然语言回答。

十二、思考模式
MiMo 系列模型,内置深度思考能力且默认开启。开启思考后,模型先通过内部思维链逐步分析问题,再输出最终答案,推理过程通过独立的 reasoning_content 字段返回,不与 content 混排。
十三、thinking 参数说明
| 字段 | 类型 | 默认值 | 取值范围 | 说明 |
| thinking.type | string | "enabled" | "enabled" / "disabled" | enabled:开启深度思考,响应中返回 reasoning_content;disabled:关闭思考直接作答,响应更快、成本更低。 |
十四、开启或关闭思考

注意:OpenAI SDK 的类型定义中没有 reasoning_content 字段,直接用属性访问会报错,必须通过安全取值方式读取:
十五、响应结构说明
开启思考时,推理过程在 reasoning_content 中返回,最终答案在 content 中返回。思考消耗的 token 计入 usage.completion_tokens 总量;当前 usage.completion_tokens_details.reasoning_tokens 恒为 0,无法单独拆分思考 token 用量:
{ "id": "2b92b0964c9b4335bffad7c2f75cfe9e", "choices": [{ "index": 0, "message": { "role": "assistant", "reasoning_content": "这是一个一元二次方程,先尝试因式分解:(x-2)(x-3) = 0,所以 x = 2 或 x = 3。", "content": "方程 x² – 5x + 6 = 0 的解为:**x = 2** 或 **x = 3**", "tool_calls": null }, "finish_reason": "stop" }], "model": "mimo-v2.5-pro", "object": "chat.completion", "usage": { "prompt_tokens": 25, "completion_tokens": 120, "total_tokens": 145, "completion_tokens_details": { "reasoning_tokens": 0 }, "prompt_tokens_details": { "cached_tokens": 0 } }}
关闭思考时,reasoning_content 不返回。
十六、流式思考输出
开启流式输出时,reasoning_content 和 content 均以增量 delta 形式返回,且 delta.reasoning_content 一定先于 delta.content 出现,需分别处理:
PythonNode.jsfrom openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)stream = client.chat.completions.create( model="mimo-v2.5-pro", messages=[{"role": "user", "content": "分析一下量子计算的优势和挑战"}], max_tokens=4096, stream=True, extra_body={"thinking": {"type": "enabled"}},)print("=== 推理过程(实时)===")answer_started = Falsefor chunk in stream: if not chunk.choices: continue delta = chunk.choices[0].delta reasoning_delta = getattr(delta, "reasoning_content", None) if reasoning_delta: print(reasoning_delta, end="", flush=True) if delta.content: if not answer_started: print("\\n\\n=== 最终答案(实时)===") answer_started = True print(delta.content, end="", flush=True)import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const stream = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: [{ role: "user", content: "分析一下量子计算的优势和挑战" }], max_tokens: 4096, stream: true, // @ts-ignore thinking: { type: "enabled" },});let answerStarted = false;process.stdout.write("=== 推理过程(实时)===\\n");for await (const chunk of stream) { const delta = chunk.choices[0]?.delta; if (!delta) continue; const reasoning = (delta as any).reasoning_content; if (reasoning) process.stdout.write(reasoning); if (delta.content) { if (!answerStarted) { process.stdout.write("\\n\\n=== 最终答案(实时)===\\n"); answerStarted = true; } process.stdout.write(delta.content); }}
十七、多轮工具调用回传 reasoning_content
开启思考模式且历史会话中存在工具调用时,后续每一轮请求中带有 tool_calls 的 assistant 消息建议完整回传 reasoning_content 字段,以保持模型的最佳表现。实测在 TokenHub 侧缺失该字段不会导致接口报错,但小米建议回传,避免历史推理内容缺失造成上下文不完整。
注意:警告:
注意:历史 reasoning_content 一旦缺失,模型上下文将不完整,即使未直接报错也可能出现指令遵循能力下降、幻觉增多等现象。使用 OpenAI SDK 时,建议直接把响应返回的 assistant 消息对象原样追加到 messages,不要手动重建或裁剪字段。
正确的回传格式如下(assistant 消息同时携带 content、reasoning_content 与 tool_calls):
{ "model": "mimo-v2.5-pro", "messages": [ {"role": "user", "content": "北京今天天气怎么样?"}, { "role": "assistant", "content": "", "reasoning_content": "用户询问北京天气,需要调用 get_weather 工具获取实时数据。", "tool_calls": [{ "id": "call_xxx", "type": "function", "function": {"name": "get_weather", "arguments": "{\\"city\\": \\"北京\\"}"} }] }, {"role": "tool", "tool_call_id": "call_xxx", "content": "晴,气温28℃,湿度50%"}, {"role": "user", "content": "那明天呢?"} ]}
注意:说明:
注意:通过 TRAE、Cursor、Codex、OpenClaw、OpenCode、Kilo Code 等 AI 编程工具接入时,工具侧一般已实现 reasoning_content 回传逻辑,无需额外处理;若自行开发 Agent 应用,请务必按上述格式处理。
十八、JSON 模式
设置 response_format 为 json_object 可以确保模型输出合法的 JSON 字符串,适合数据抽取、表单填充、分类打标等需要结构化数据的场景。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/chat/completions \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "messages": [ {"role": "system", "content": "只返回 JSON,不要附带任何解释、注释或 Markdown 代码块。格式:{\\"cities\\": [{\\"name\\": string, \\"province\\": string, \\"population\\": number}]}"}, {"role": "user", "content": "返回三座中国城市的信息"} ], "max_tokens": 2048, "response_format": {"type": "json_object"} }'import jsonfrom openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)response = client.chat.completions.create( model="mimo-v2.5-pro", messages=[ { "role": "system", "content": ( "只返回 JSON,不要附带任何解释、注释或 Markdown 代码块。\\n" '格式:{"cities": [{"name": string, "province": string, "population": number}]}\\n' "未知字段请填充 null。" ), }, {"role": "user", "content": "返回三座中国城市的信息"}, ], max_tokens=2048, response_format={"type": "json_object"},)try: result = json.loads(response.choices[0].message.content) print(json.dumps(result, ensure_ascii=False, indent=2))except json.JSONDecodeError as e: print(f"JSON 解析失败:{e}") print(f"原始内容:{response.choices[0].message.content}")import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const response = await client.chat.completions.create({ model: "mimo-v2.5-pro", messages: [ { role: "system", content: '只返回 JSON,不要附带任何解释、注释或 Markdown 代码块。格式:{"cities": [{"name": string, "province": string, "population": number}]}', }, { role: "user", content: "返回三座中国城市的信息" }, ], max_tokens: 2048, response_format: { type: "json_object" },});const result = JSON.parse(response.choices[0].message.content);console.log(JSON.stringify(result, null, 2));JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("max_tokens", 2048);body.put("response_format", new JSONObject().put("type", "json_object"));body.put("messages", new JSONArray() .put(new JSONObject().put("role", "system").put("content", "只返回 JSON,不要附带任何解释。")) .put(new JSONObject().put("role", "user").put("content", "返回三座中国城市的信息")));// … 发送请求,解析返回的 JSON 字符串body := map[string]interface{}{ "model": "mimo-v2.5-pro", "max_tokens": 2048, "response_format": map[string]string{"type": "json_object"}, "messages": []map[string]string{ {"role": "system", "content": "只返回 JSON,不要附带任何解释。"}, {"role": "user", "content": "返回三座中国城市的信息"}, },}// … 发送请求
十九、Anthropic Messages 协议调用
MiMo 系列模型支持 Anthropic Messages 协议,可直接使用 Anthropic SDK 或兼容客户端(Claude Code、OpenClaw、Cline 等)接入。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/messages \\ -H "Content-Type: application/json" \\ -H "x-api-key: YOUR_API_KEY" \\ -H "anthropic-version: 2023-06-01" \\ -d '{ "model": "mimo-v2.5-pro", "max_tokens": 2048, "system": "你是一个专业的技术助手,回答简洁准确。", "messages": [ {"role": "user", "content": "介绍一下 MoE 架构的优势"} ] }'# pip install anthropicfrom anthropic import Anthropicclient = Anthropic( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com",)message = client.messages.create( model="mimo-v2.5-pro", max_tokens=2048, system="你是一个专业的技术助手,回答简洁准确。", messages=[ {"role": "user", "content": "介绍一下 MoE 架构的优势"} ],)print(message.content[0].text)// npm install @anthropic-ai/sdkimport Anthropic from "@anthropic-ai/sdk";const client = new Anthropic({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com",});const message = await client.messages.create({ model: "mimo-v2.5-pro", max_tokens: 2048, system: "你是一个专业的技术助手,回答简洁准确。", messages: [ { role: "user", content: "介绍一下 MoE 架构的优势" } ],});console.log(message.content[0].text);import okhttp3.*;import org.json.*;OkHttpClient httpClient = new OkHttpClient();JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("max_tokens", 2048);body.put("system", "你是一个专业的技术助手,回答简洁准确。");body.put("messages", new JSONArray() .put(new JSONObject().put("role", "user").put("content", "介绍一下 MoE 架构的优势")));Request request = new Request.Builder() .url("https://tokenhub.tencentmaas.com/v1/messages") .addHeader("x-api-key", "YOUR_API_KEY") .addHeader("anthropic-version", "2023-06-01") .addHeader("Content-Type", "application/json") .post(RequestBody.create(body.toString(), MediaType.get("application/json"))) .build();try (Response response = httpClient.newCall(request).execute()) { JSONObject result = new JSONObject(response.body().string()); System.out.println(result.getJSONArray("content").getJSONObject(0).getString("text"));}body := map[string]interface{}{ "model": "mimo-v2.5-pro", "max_tokens": 2048, "system": "你是一个专业的技术助手,回答简洁准确。", "messages": []map[string]string{ {"role": "user", "content": "介绍一下 MoE 架构的优势"}, },}data, _ := json.Marshal(body)req, _ := http.NewRequest("POST", "https://tokenhub.tencentmaas.com/v1/messages", bytes.NewBuffer(data))req.Header.Set("x-api-key", "YOUR_API_KEY")req.Header.Set("anthropic-version", "2023-06-01")req.Header.Set("Content-Type", "application/json")// … 发送请求,从 content[0].text 读取回复
20、Responses API 协议调用
MiMo 系列模型支持 OpenAI Responses 协议,可用于新版 Codex 等基于 Responses 接口的客户端接入。请求路径为 /v1/responses,认证方式与 Chat Completions 一致。
注意:说明:
注意:Responses 协议使用 input 传入对话内容、max_output_tokens 控制输出长度(与 Chat Completions 的 messages、max_tokens 相对应)。完整字段说明与兼容性范围请参见 OpenAI Response 协议字段说明 与 Responses API 兼容模式说明。
cURLPythonNode.jsJavaGocurl https://tokenhub.tencentmaas.com/v1/responses \\ -H "Content-Type: application/json" \\ -H "Authorization: Bearer YOUR_API_KEY" \\ -d '{ "model": "mimo-v2.5-pro", "input": "介绍一下 MoE 架构的优势", "max_output_tokens": 2048 }'from openai import OpenAIclient = OpenAI( api_key="YOUR_API_KEY", base_url="https://tokenhub.tencentmaas.com/v1",)response = client.responses.create( model="mimo-v2.5-pro", input="介绍一下 MoE 架构的优势", max_output_tokens=2048,)print(response.output_text)import OpenAI from "openai";const client = new OpenAI({ apiKey: "YOUR_API_KEY", baseURL: "https://tokenhub.tencentmaas.com/v1",});const response = await client.responses.create({ model: "mimo-v2.5-pro", input: "介绍一下 MoE 架构的优势", max_output_tokens: 2048,});console.log(response.output_text);JSONObject body = new JSONObject();body.put("model", "mimo-v2.5-pro");body.put("input", "介绍一下 MoE 架构的优势");body.put("max_output_tokens", 2048);Request request = new Request.Builder() .url("https://tokenhub.tencentmaas.com/v1/responses") .addHeader("Authorization", "Bearer YOUR_API_KEY") .addHeader("Content-Type", "application/json") .post(RequestBody.create(body.toString(), MediaType.get("application/json"))) .build();// … 发送请求,从 output 数组中读取文本内容body := map[string]interface{}{ "model": "mimo-v2.5-pro", "input": "介绍一下 MoE 架构的优势", "max_output_tokens": 2048,}data, _ := json.Marshal(body)req, _ := http.NewRequest("POST", "https://tokenhub.tencentmaas.com/v1/responses", bytes.NewBuffer(data))req.Header.Set("Authorization", "Bearer YOUR_API_KEY")req.Header.Set("Content-Type", "application/json")// … 发送请求,从 output 数组中读取文本内容
21、与其他模型的关键差异
| 维度 | MiMo 系列模型 | OpenAI / Claude / GLM 等 |
| 思考能力开关 | 通过 thinking.type 控制(enabled/disabled),默认开启 | 通常通过切换 model 或单独的 reasoning 参数控制 |
| 推理过程字段 | 独立 reasoning_content 字段返回,不嵌入 content | 多数模型不暴露推理过程 |
| OpenAI SDK 访问推理字段 | 必须用 getattr / as any | – |
| 思考模式下的采样参数 | temperature、top_p 不可自定义,强制为 1.0 / 0.95 | 通常可自由设置 |
| temperature 范围 | 0-1.5,默认 1.0 | 通常 0-2 |
| top_p 范围 | 0.01-1.0,默认 0.95 | 通常 0-1 |
| 多轮工具调用回写 | 含工具调用时建议回写 reasoning_content(缺失不报错) | 通常只需回写 content |
| tool_choice | 仅支持 auto | 通常支持 none/required/指定函数 |
| 结构化输出 | 仅支持 json_object | 多数支持 json_schema |
| 上下文窗口 | 1M tokens | 通常 128K tokens |
| 最大输出 | 128K tokens | 通常 16K tokens |
| 多模态输入 | 不支持,仅文本输入 | 部分模型支持图片/视频 |
22、推荐参数与最佳实践
| 参数 / 实践 | 建议 | 说明 |
| max_tokens | 普通任务 2048-4096;复杂推理建议 ≥ 8192 | 思考内容与最终答案共享 token 配额,取值过小会导致答案被截断 |
| thinking.type | 复杂推理、代码生成、Agent 任务保持默认 enabled;简单问答、格式转换改为 disabled | 关闭思考可显著降低延迟与成本 |
| stream | 开启思考时建议开启 | 思考耗时较长,流式可避免超时并实时呈现推理过程 |
| temperature | 关闭思考时可按需调整(创意写作 1.2-1.5,代码生成 0.2-0.5);开启思考时无需设置 | 取值范围 0-1.5,思考模式下会被强制为 1.0 |
| top_p | 与 temperature 二选一,不建议同时调整 | 取值范围 0.01-1.0,默认 0.95 |
| System Prompt | 建议声明模型身份与当前日期 | 提升时间类问题准确度,模板参见这篇「通用调用示例 > System Prompt」 |
| 多轮对话 | 纯对话只回写 content;含工具调用建议完整回写 reasoning_content | 前者节省 token,后者为最佳实践(缺失不报错) |
| SDK 访问推理字段 | Python 用 getattr(msg, "reasoning_content", None);Node.js 用 (msg as any).reasoning_content | OpenAI SDK 类型定义中无此字段 |
| 上下文缓存 | 无需配置,自动生效 | 隐式缓存自动开启,命中量见 usage.prompt_tokens_details.cached_tokens |
23、使用限制
| 限制项 | 说明 |
| 思考模式采样参数 | 开启思考时不支持自定义 temperature 和 top_p,传入后实际生效值为 1.0 和 0.95。 |
| 多轮工具调用 | 开启思考且历史存在工具调用时,建议完整回传 reasoning_content;缺失不会报错,但可能影响指令遵循与输出质量。 |
| tool_choice | 仅支持 auto,传入其他值时该字段会被忽略。 |
| 工具函数名 | 仅允许 a-z、A-Z、0-9、下划线、连字符,长度 1-64。 |
| 结构化输出 | response_format 仅支持 json_object,不支持 json_schema。 |
| 超时风险 | 开启思考时响应时间较长,建议配合 stream=true 使用,避免超时。 |
| finish_reason | 除 stop/length/tool_calls/content_filter 外,模型检测到复读时会返回 repetition_truncation。 |
| 协议差异 | Anthropic Messages 协议使用 x-api-key 认证且 max_tokens 必填;Responses 协议使用 input 与 max_output_tokens,字段命名与 Chat Completions 不同。 |
