    false 在 qwen3.8-flash 生效；deepseek-v4-flash 接受但不生效；glm-5.3-flash 的两面结果不一致。

  • pluginsarray可选◐ 部分支持

    Plugins you want to enable for this request, including their settings.

    支持 file-parser（pdf.engine 为 native、mistral-ocr→ocr、ocr、auto）和平台 guardrails。请求覆盖账户默认，锁定设置保留。web 等未实现插件、未知引擎或非法形状返回 400 并点名字段。

    ▸ 展开子字段（27）

    元素按 id 区分（auto-beta-router / auto-router / context-compression / file-parser / fusion / moderation / pareto-router / response-healing / web / web-fetch），此处展开其中一种的形状

    • allowed_modelsarray可选

      List of model patterns to filter which models the auto-beta-router can route between. Supports wildcards (e.g., "anthropic/*" matches all Anthropic models). Up to 1024 patterns, each at most 1024 characters, with 65536 total characters across all patterns. When not specified, every model ranked for the classified task type is a candidate, falling back to a default model set when rankings are unavailable.

    • cost_quality_tradeoffinteger可选

      Deprecated: Use cost_tier instead. Balances routing between cost and quality on a 0-10 scale. The auto-beta-router ranks models for the classified task type by community spend share, then filters candidates by their average cost per generation for that task. Higher values favor cheaper models: 10 keeps only models around the cheapest 10th percentile, while 0 permits models up to the 90th percentile for cost. Defaults to 9 when no cost setting is provided. It remains supported and retains ceiling behavior, but cost_tier takes precedence when both are provided.

    • cost_tierstring可选

      Named cost/quality setting. For auto-beta-router, tiers select cost-percentile bands: low = [0, 20), medium = [20, 40), high = [40, 60), xhigh = [60, 80), and max = [80, 100]. Takes precedence over the deprecated numeric cost_quality_tradeoff when both are provided.

      取值 lowmediumhighxhighmax
    • enabledboolean可选

      Set to false to disable Fusion configuration for a run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool. Defaults to true.

    • excluded_modelsarray可选

      List of model patterns to exclude from auto-beta-router selection. Supports wildcards (e.g., "meta-llama/*" excludes all Llama models). Up to 1024 patterns, each at most 1024 characters, with 65536 total characters across all patterns. Applied after allowed_models, so an excluded pattern always wins over an allowed one.

    • idstring可选

      Plugin id; always fusion.

      取值 fusion
    • pin_modelboolean可选

      When true, reuses the model from the most recent assistant message's `model` attribute for subsequent turns. Defaults to false.

    • enginestring可选

      The compression engine to use. Defaults to "middle-out".

      取值 middle-out
    • exclude_domainsarray可选

      A list of domains to exclude from web search results. Supports wildcards (e.g. "*.substack.com") and path filtering (e.g. "openai.com/blog").

    • include_domainsarray可选

      A list of domains to restrict web search results to. Supports wildcards (e.g. "*.substack.com") and path filtering (e.g. "openai.com/blog").

    • max_resultsinteger可选

      Maximum number of search results to use.

    • max_usesinteger可选

      Maximum number of web fetches per request. Once exceeded, the tool returns an error.

    • modestring可选

    • search_promptstring可选

      Prompt that introduces the search results to the model.

    • user_locationobject可选

      Only fetch from these domains.

    • blocked_domainsarray可选

      Never fetch from these domains.

    • max_content_tokensinteger可选

      Maximum content length in approximate tokens. Content exceeding this limit is truncated.

    • pdfobject可选

      Options for PDF parsing.

    • max_pricenumber可选

      Maximum input price in USD per million tokens. When set, quality-tier selection (min_coding_score) is bypassed: the router computes the Pareto frontier over the top coding models and routes to the best-scoring frontier model priced at or below this cap, falling back through cheaper frontier models, then non-frontier models. Enforced against the price source given by price_source. Returns 404 when no candidate satisfies the cap.

    • min_coding_scorenumber可选

      Minimum coding quality score between 0 and 1. Maps to internal quality tiers: >= 0.66 → high (top coding models), >= 0.33 → medium (strong modern flagships), < 0.33 → low (capable coders above the median). Omit to default to the highest tier (equivalent to >= 0.66). Not used when max_price is set (price-based selection takes over).

    • price_sourcestring可选

      Price source for the Pareto frontier cost axis and for enforcing max_price. "prompt" uses catalog list price (endpoint.pricing.prompt). "weighted_avg" uses traffic-weighted effective input price from ClickHouse, falling back to prompt price for models without traffic data. Defaults to "prompt".

      取值 promptweighted_avg
    • analysis_modelsarray可选

      For a Fusion run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool, slugs of models to run in parallel as the "expert panel" the analyst analyzes. Each model receives the same user prompt with web_search + web_fetch enabled. Capped at 8 models to bound cost amplification. When omitted, defaults to the Quality preset from the /labs/fusion UI (~anthropic/claude-opus-latest, ~openai/gpt-sol-latest, ~google/gemini-pro-latest).

    • max_tool_callsinteger可选

      For a Fusion run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool, the maximum number of tool-calling steps each panelist (analysis model) and the analyst model may take during their agentic web-research loop. Models with web_search/web_fetch enabled iterate until they produce a text response or hit this ceiling. Defaults to 4. Capped at 16.

    • modelstring必填

      For a Fusion run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool, the slug of the model that performs both the analyst step (with web_search + web_fetch) and the final synthesis. When omitted, defaults to the first model in the Quality preset.

    • presetstring可选

      Configuration for a Fusion run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool. A curated OpenRouter preset (slugs follow `<task>-<tier>`, e.g. `general-high`). Expands server-side into the preset's analysis_models panel and analyst model, so callers never name individual models. Explicitly provided `analysis_models` / `model` take precedence.

      取值 general-highgeneral-budgetgeneral-fast
    • toolsarray可选

      For a Fusion run started by the `openrouter/fusion` model slug or `openrouter:fusion` server tool, server tools available to panelist and analyst inner calls. Each entry uses the same `{ type, parameters? }` shorthand as the outer Chat Completions request. When omitted, defaults to `[{ type: "openrouter:web_search" }, { type: "openrouter:web_fetch" }]`. Pass an empty array to disable tools entirely (panelists answer from parametric knowledge only).

  • predictionobject可选

    Static predicted output content. Supported models can use this to reduce latency when much of the response is known in advance.

    ▸ 展开子字段（2）

    • contentstring | array必填

      Predicted output: a string or an array of text parts.

    • typestring必填

      取值 content
  • presence_penaltynumber可选◐ 部分支持

    Presence penalty (-2.0 to 2.0)

    deepseek-v4-flash 的 /openai 面观察到效果；qwen3.8-flash 部分请求返回 400，其余不可观测。

  • prompt_cache_keystring可选

    Caller-chosen key that groups requests with a long shared prefix so that they can reuse the provider's prompt cache; null for none.

  • prompt_cache_optionsobject可选

    Request-level prompt-cache controls. `mode: "explicit"` disables OpenAI-managed breakpoints so only blocks marked with `prompt_cache_breakpoint` are cached. Only supported by OpenAI GPT-5.6 and newer.

    ▸ 展开子字段（2）

    • modestring必填

      Prompt cache mode; explicit caches only the blocks marked with prompt_cache_breakpoint.

      取值 explicit
    • ttlstring可选

      Lifetime of cache entries, for example 30m; null leaves the provider default.

  • providerobject可选◐ 部分支持

      选择具体供应商（order / only / ignore）仅限 BYOK，平台凭证下返回 400 PROVIDER_SELECTION_NOT_ALLOWED。

    • preferred_max_latencynumber | object可选

      Preferred maximum latency (in seconds). Can be a number (applies to p50) or an object with percentile-specific cutoffs. Endpoints above the threshold(s) may still be used, but are deprioritized in routing. When using fallback models, this may cause a fallback model to be used instead of the primary model if it meets the threshold.

    • preferred_min_throughputnumber | object可选

      Preferred minimum throughput (in tokens per second). Can be a number (applies to p50) or an object with percentile-specific cutoffs.

    取值 maxxhighhighmediumlowminimalnonenull
  • repetition_penaltynumber可选

    Penalizes tokens based on how much they have already appeared in the text. A value of 1.0 means no penalty. Values above 1.0 penalize repeated tokens more strongly. Not all providers support this parameter.

  • routestring可选

    **DEPRECATED** Use providers.sort.partition instead. Backwards-compatible alias for providers.sort.partition. Accepts legacy values: "fallback" (maps to "model"), "sort" (maps to "none").

    取值 fallbacksortnull
  • seedinteger可选○ 当前不生效

    取值 autodefaultfastflexpriorityscalenull
  • session_idstring可选

    A unique identifier for grouping related requests (e.g., a conversation or agent workflow). When provided, OpenRouter uses it as the sticky routing key, routing all requests in the session to the same provider to maximize prompt cache hits. Also used for observability grouping. If provided in both the request body and the x-session-id header, the body value takes precedence. Maximum of 256 characters.

  • stopstring | array可选◐ 部分支持

    Stop sequences (up to 4)

    qwen3.8-flash 生效；deepseek-v4-flash、glm-5.3-flash 可能截断思考并返回空正文。

  • stop_server_tools_whenarray可选

    Stop conditions for the server-tool agent loop. Any condition firing halts the loop (OR logic). When set, this overrides `max_tool_calls`. When a condition fires while the model is still emitting tool calls, the pending tool calls are executed and one final turn is made with tool calls disabled so the response ends with a natural-language answer instead of an unfinished tool call.

  • userstring可选

    Per-end-user identifier for abuse isolation. Use a stable ID, hash, or pseudonym. When a provider requires a user identity, OpenRouter folds it into the hashed identity sent upstream and never forwards it raw. If omitted, requests use an account-level identity, so provider policy blocks can affect the whole account.
