About Muse Spark 1.1
Muse Spark 1.1 是 Meta Model API 上线时的首个版本，面向智能体与编程任务，支持图片、视频、音频与 PDF 输入和 100 万 token 上下文。
支持 1,048,576 token 上下文、工具调用、JSON Schema 结构化输出和自动提示缓存。模型始终先思考再作答，思考 token 计入输出，但不返回思考过程。
Use cases and prompting
通过 OpenAI 兼容的 POST /v1/chat/completions 调用，model 填 muse-spark-1.1。需要保留多轮推理或内置联网搜索时，使用 POST /v1/responses 或 POST /v1/messages；Chat Completions 不提供内置联网搜索。
思考强度可选 minimal / low / medium / high / xhigh，none 不受支持。Chat 使用 reasoning_effort，Responses 使用 reasoning.effort。图片、视频、PDF 等通过公网 URL 或内联 base64 传入；不支持 /v1/files 上传。
美元基础价（每百万 token）：输入 $1.25，输出 $4.25，缓存读取 $0.15。内置联网搜索为 $2.50/千次查询，另加搜索内容对应的 token 费用。

/v1/chat/completions| Parameter | Type | Default / range | Description |
|---|---|---|---|
temperature | number | = 10 ~ 2 | Sampling temperature; lower is more deterministic |
top_p | number | = 10 ~ 1 | Nucleus sampling probability mass |
max_tokens | integer | >= 1 | Maximum number of tokens in the response |
frequency_penalty | number | = 0-2 ~ 2 | Penalises repetition of frequent tokens |
presence_penalty | number | = 0-2 ~ 2 | Encourages introducing new topics |
stop | array | — | Up to 4 strings that stop generation |
seed | integer | — | Deterministic sampling seed (best-effort) |
n | integer | = 1>= 1 | Number of completions to generate |
stream | boolean | = false | Stream tokens via Server-Sent Events |
response_format | object | — | Force JSON object or schema-conforming output |
tools | array | — | Tool / function declarations the model may call |
tool_choice | string | autononerequired | Tool-choice policy or specific tool name |
logprobs | boolean | = false | Return per-token log probabilities |
top_logprobs | integer | 0 ~ 20 | Number of top log probabilities returned per token |
logit_bias | object | — | Per-token logit bias map |
user | string | — | End-user identifier for abuse monitoring |
Replace <YOUR_API_KEY> with the API key from your token settings.
Authentication
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.
