qwen3-max

alibaba/qwen3-max — a llm model by Alibaba. Call it through the gateway’s standard OpenAI-compatible door using the catalog slug; the full parameter schema is reproduced in full below.

Catalog slug	alibaba/qwen3-max
Kind	llm
Vendor	Alibaba

How to call

Through the Sociaro SDK / OpenAI-compatible door

from sociaro_ai import Sociaro

client = Sociaro(api_key="gw_live_...")   # base_url defaults to https://api.sociaro.com

resp = client.chat.completions.create(
    model="alibaba/qwen3-max",          # always the catalog slug
    messages=[{"role": "user", "content": "Hello"}],
    # any parameter from the schema below is passed through unchanged
)
print(resp.choices[0].message.content)

TypeScript: client.chat.completions.create({ model: "alibaba/qwen3-max", messages: [...] }) — see the TypeScript SDK.

Parameters — full schema

The complete, one-to-one API schema for this model, transcribed from the official source. Nothing omitted. Examples in the schema may use a representative model of the family — for this model use the slug alibaba/qwen3-max as shown in How to call above.

Scope / model coverage map

A SINGLE OpenAI-compatible contract (POST .../compatible-mode/v1/chat/completions) covers all Qwen text-chat families. There is no per-model parameter reference; only defaults and per-feature support lists differ. The same endpoint also serves Qwen-VL, Qwen-Omni, Qwen-Math, Qwen-Coder, and third-party models (DeepSeek, Kimi, GLM, MiniMax) routed through Model Studio.

Family / model group	Same /chat/completions contract	Notable family-specific behavior
qwen3.7-max / qwen3.7-plus	yes	thinking ON by default; max_completion_tokens, tool_stream, preserve_thinking supported
qwen3.6-max / qwen3.6-plus / qwen3.6-flash	yes	thinking ON by default; tool_stream (plus/flash); preserve_thinking (plus)
qwen3.5-plus / qwen3.5-flash	yes	thinking ON by default; max_completion_tokens; tool_stream; search_strategy=agent
qwen3-max / qwen-max	yes	qwen3-max: thinking OFF by default; search_strategy=agent, agent_max (thinking only)
qwen-plus / qwen-flash	yes	hybrid thinking OFF by default; presence_penalty default 0.5 in thinking mode
qwen3-coder-flash / -next / -plus	yes	text-chat contract; thinking-family rules apply per snapshot
qwen3 open-source (8b/14b/32b/30b-a3b/235b-a22b, -instruct/-thinking)	yes	n (1-4) only in non-thinking mode; logprobs supported; /think /no_think suffixes
Qwen-VL / Qwen3-VL	yes	adds multimodal content parts + vl_high_resolution_images, min/max/total_pixels, fps
Qwen-Omni (qwen3.5-omni-*, Qwen3-Omni-Flash)	yes	adds modalities, audio; audio output tokens
DeepSeek (v3.x/v4/r1)	yes	uses reasoning_effort (V4); enable_thinking for V4/V3.x; does NOT support top_k
Kimi (k2.x)	yes	thinking_budget supported; preserve_thinking (k2.6/k2.7-code); no top_k
GLM (4.6/4.7/5/5.1)	yes	tool_stream; top_k default 20 (Alibaba direct); thinking ON by default
MiniMax (M2.x/M3)	yes	uses thinking object instead of enable_thinking; no top_k

Note: qwen-mt-* (machine translation) is a different family. It also posts to /chat/completions but adds a translation_options object (source_lang/target_lang/terms/tm_list/domains) that is NOT part of this chat contract.

Critical per-model differences (quick reference)

• enable_thinking default is per-model — NOT a fixed global default:
  • thinking ON by default: qwen3.7-max/plus, qwen3.6-max/plus/flash, qwen3.5-plus/flash, all open-source qwen3.5/qwen3.6/qwen3 hybrid models, GLM series (glm-4.5+).
  • thinking OFF by default: qwen3-max, qwen-max, qwen-plus, qwen-flash, DeepSeek-V4/V3.x (commercial hybrid), Kimi k2.6/k2.5.
  • thinking-only (cannot disable, no enable_thinking needed): qwen3.7-max-preview, qwen3-*-thinking, kimi-k2.7-code, deepseek-r1 family, MiniMax-M2.5/M2.1.
• max_completion_tokens support: Qwen3.7-Max+, Qwen3.5-Plus+, Qwen3.5-Flash+, Kimi k2.5+, GLM glm-5+, MiniMax-M2.5+, DeepSeek (v3/r1/v3.1/v3.2/v4 list). Third-party direct-sale models excluded.
• n (1-4): ONLY Qwen3 non-thinking mode; set n=1 when tools is passed.
• presence_penalty default: 1.5 / 0.5 / 0.0 / 1 by model (full table below).
• top_k default: 20 (most); Qwen3-Omni-Flash 50; GLM (Alibaba direct) 20. DeepSeek/Kimi/MiniMax do NOT support top_k.
• reasoning_effort: ONLY DeepSeek-V4 (deepseek-v4-pro/-flash). Not for Qwen.
• thinking object: ONLY MiniMax/MiniMax-M3 (Xiyu direct). Qwen uses enable_thinking.
• tool_stream: qwen3.7-max/plus, qwen3.6-plus/flash, qwen3.5-plus/flash + GLM (4.6/4.7/5/5.1).
• preserve_thinking: qwen3.7-max(+snapshots/-preview/-2026-05-17), qwen3.6-max-preview, qwen3.7-plus(-2026-05-26), qwen3.6-plus(-2026-04-02), kimi-k2.6, kimi-k2.7-code (and Moonshot-direct equivalents). NOT qwen3.5 / qwen-coder.
• search_strategy=agent/agent_max: limited list (qwen3.5-plus/flash, qwen3-max, qwen3.5-omni-plus/flash); agent_max only thinking-mode qwen3-max.
• logprobs: qwen-plus snapshots (not stable), qwen3-vl-plus/flash (incl. stable), Qwen3 open-source.

Request body — shape

{
  "model": "qwen-plus",
  "messages": [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Who are you?"}
  ]
}

DashScope extensions (enable_thinking, thinking, thinking_budget, preserve_thinking, reasoning_effort, enable_search, search_options, top_k, repetition_penalty, vl_high_resolution_images, tool_stream, enable_code_interpreter) are not standard OpenAI parameters. Via the Python OpenAI SDK they go inside extra_body={...}. Via direct HTTP/curl they go at the JSON body root.

Correctness guard: frequency_penalty is NOT supported in DashScope’s OpenAI-compatible mode. The source exposes only presence_penalty (verified: the compatibility page contains frequency_penalty 0 times). Do not add frequency_penalty. Constraint: streaming output cannot be combined with the tools parameter (per compatibility page); and when using tools, set n=1.

Request — ALL parameters (top-level)

Parameter	Type	Required	Default	Allowed values / range	Description
model	string	Yes	—	a model name (Qwen LLM commercial/open-source, Qwen-VL, Qwen-Coder, Qwen-Omni, Qwen-Math; DeepSeek, Kimi, GLM, MiniMax)	The model to call. Exact names + billing: check console.
messages	array	Yes	—	chronological message array	Conversation history. Message types: System / User / Assistant / Tool (nested spec below).
stream	boolean	No	false	true | false	Streaming (SSE). false returns full content after generation; true returns chunks incrementally. For non-stream calls, if the request does not finish within 300 s the service interrupts and returns content generated so far (not an error) — prefer true for long outputs.
stream_options	object	No	—	effective only when stream=true	Streaming options. Property include_usage (boolean, default false): include token-usage info in the last chunk.
modalities	array	No	["text"]	["text"] | ["text","audio"]	Qwen-Omni only. Output modalities.
audio	object	No	—	requires modalities=["text","audio"]	Qwen-Omni only. Output audio config. Properties: voice (string, Required); format (string, Required) — only wav.
temperature	float	No	model-dependent	0 ≤ x < 2	Sampling temperature. Set EITHER temperature OR top_p, not both.
top_p	float	No	model-dependent	(0, 1.0]	Nucleus sampling. Set EITHER temperature OR top_p.
top_k	integer	No	20 (most); Qwen3-Omni-Flash 50; GLM (Alibaba direct) 20	integer ≥ 0; null or >100 disables top_k (only top_p applies)	Candidate-token count for sampling. Non-standard OpenAI → extra_body. DeepSeek/Kimi/MiniMax do NOT support it.
repetition_penalty	float	No	model-dependent	> 0, no strict upper limit; 1.0 = no penalty	Penalty on repeated consecutive sequences. Non-standard → extra_body.
presence_penalty	float	No	model-dependent (table below)	-2.0 … 2.0	Penalty on tokens already present. Positive reduces repetition; negative increases. Supported by commercial Qwen + open-source models.
response_format	object	No	{"type":"text"}	{"type":"text"} | {"type":"json_object"}	Response format. For json_object you MUST also instruct JSON in the prompt or an error occurs. Property type (string, Required): text | json_object.
max_tokens	integer	No (Deprecated)	model max output length	integer	Deprecated — use max_completion_tokens. Caps response tokens; on hit finish_reason="length". Does NOT limit chain-of-thought length.
max_completion_tokens	integer	No	model max output length	integer	Caps total response tokens including chain-of-thought; on hit finish_reason="length". Recommended for reasoning models. Supported: Qwen3.7-Max+, Qwen3.5-Plus+, Qwen3.5-Flash+, Kimi k2.5+, GLM glm-5+, MiniMax-M2.5+, DeepSeek (v3/r1/r1-0528/v3.1/v3.2/v3.2-exp/v4-pro/v4-flash and later). Third-party direct-sale models excluded. Actual output may differ by up to 10 tokens.
vl_high_resolution_images	boolean	No	false	true | false	Qwen-VL only. Raises image pixel cap to the 16384-token equivalent (fixed-resolution strategy, ignores max_pixels). true cap: Qwen3.7/3.6/3.5/Qwen3-VL → 16777216 px (32×32/token). Non-standard → extra_body.
n	integer	No	1	1 … 4	Number of candidate responses. Only Qwen3 non-thinking mode. Set to 1 when tools is passed. Increases only output tokens (not input).
enable_thinking	boolean	No	model-dependent (see per-model differences)	true | false	Toggles hybrid thinking. Models: Qwen3.7/3.6/3.5/Qwen3/Qwen3-Omni-Flash/Qwen3-VL, DeepSeek-V4-Pro/V4-Flash, DeepSeek-V3.2/V3.2-exp/V3.1, Kimi-K2.7-code (thinking-only)/K2.6/K2.5, GLM. When true, reasoning returns in reasoning_content. Non-standard → extra_body. MiniMax/MiniMax-M3 (Xiyu direct) uses thinking instead.
thinking	object	No	{"type":"adaptive"}	type: adaptive | disabled	MiniMax/MiniMax-M3 (Xiyu direct) only. adaptive = model decides; disabled = no thinking. Non-standard → extra_body.
preserve_thinking	boolean	No	false	true | false	Re-feed prior assistant reasoning_content into input. Models: qwen3.7-max (+ -2026-05-20/-06-08 snapshots, -preview, -2026-05-17), qwen3.6-max-preview, qwen3.7-plus(-2026-05-26), qwen3.6-plus(-2026-04-02), kimi-k2.6, kimi-k2.7-code (default-on), kimi/kimi-k2.7-code (Moonshot direct, default-on). Re-fed reasoning is billed as input. Enabling with no prior reasoning_content is not an error. Non-standard → extra_body.
thinking_budget	integer	No	model max chain-of-thought length	integer	Max tokens for the thinking process; on reaching it the model stops reasoning and answers. Supported by Qwen3 (in thinking mode) — Qwen3.7, Qwen3.6, Qwen3.5, Qwen3-VL and the Qwen3 commercial and open-source models — and by Kimi models. Non-standard → extra_body.
reasoning_effort	string	No	high	high | max (low/medium→high, xhigh→max)	DeepSeek-V4 only (deepseek-v4-pro/-flash). Reasoning intensity. Non-standard → extra_body.
tool_stream	boolean	No	false	true | false; effective only when stream=true	Stream complex tool arguments (array/object types). Qwen: qwen3.7-max (text), qwen3.7-plus/qwen3.6-plus (text), qwen3.5-plus (all modalities), qwen3.6-flash/qwen3.5-flash (all modalities). GLM: glm-4.6/4.7/5/5.1. Simple args stream whenever stream=true. Non-standard → extra_body.
enable_code_interpreter	boolean	No	false	true | false	Enables the code interpreter feature. Non-standard → extra_body.
seed	integer	No	—	[0, 2^31−1]	RNG seed for reproducibility (same seed + unchanged params → same result when possible).
logprobs	boolean	No	false	true | false	Return log-probabilities of output tokens (reasoning_content excluded). Models: qwen-plus snapshots (not stable), qwen3-vl-plus (incl. stable), qwen3-vl-flash (incl. stable), Qwen3 open-source.
top_logprobs	integer	No	0	0 … 5	Number of top candidate tokens per step. Effective only when logprobs=true.
stop	string or array	No	—	string / array of strings or token_ids	Stop words: generation stops immediately on appearance. Do NOT mix strings and token_ids in one array (e.g. ["Hello",104307] is invalid).
tools	array	No	—	array of tool objects	Function-calling tool definitions. When a tool fires, the response carries tool_calls. Properties: type (string, Required, only function); function (object, Required) → name (string, Required; letters/digits/_/-; ≤64 tokens), description (string, Required), parameters (object, Optional, default {}, valid JSON Schema).
tool_choice	string or object	No	auto	auto | none | {"type":"function","function":{"name":"..."}}	Tool-selection policy. none disables; object forces a specific tool. Thinking-mode models cannot force a specific tool.
parallel_tool_calls	boolean	No	false	true | false	Enable parallel tool calling.
enable_search	boolean	No	false	true | false	Enable web search. May increase token usage. If search does not trigger, optimize the prompt or set search_options.forced_search. Non-standard → extra_body.
search_options	object	No	—	effective only when enable_search=true	Web-search strategy (sub-properties below). Non-standard → extra_body.

search_options — sub-properties

Property	Type	Required	Default	Allowed values	Description
forced_search	boolean	Optional	false	true | false	Force web search (true) vs. let the model decide (false). Effective only when enable_search=true.
search_strategy	string	Optional	turbo	turbo | max | agent | agent_max	turbo = balanced; max = broader multi-engine search (slower); agent = multi-round retrieve+integrate (only qwen3.5-plus/-2026-02-15, qwen3.5-flash/-2026-02-23, qwen3-max/-2026-01-23/-2025-09-23, qwen3.5-omni-plus/-2026-03-15, qwen3.5-omni-flash/-2026-03-15); agent_max = agent + web extraction (only thinking-mode qwen3-max & qwen3-max-2026-01-23).
enable_search_extension	boolean	Optional	false	true | false	Domain-specific search. Effective only when enable_search=true.

DashScope-native protocol additionally exposes enable_source (return search sources in output.search_info.search_results); this is a DashScope-API field, not part of the OpenAI-compatible body.

}

Field	Type	Description

---

Response — streaming (object: "chat.completion.chunk")

Each chunk:

• id (shared across all chunks of one response)
• choices[] with:
  • delta: content (string, incremental), reasoning_content (string, incremental CoT), function_call (null), audio{data (Base64, incremental), expires_at (UNIX ts)} (Qwen-Omni), refusal (null), role (first chunk only), tool_calls[]{index, id, function{arguments (concatenate across chunks), name (first chunk only)}, type (function)}
  • finish_reason: stop | length | tool_calls | null (before completion)
  • index (integer; use to reassemble per-candidate output when n>1)
  • logprobs (object, same shape as non-stream)
• created, model, object (chat.completion.chunk), service_tier (null), system_fingerprint (null)
• usage: present only in the final chunk when stream_options.include_usage=true; in that final chunk choices is empty.

In streaming usage, completion_tokens_details carries real audio_tokens/reasoning_tokens/text_tokens, and prompt_tokens_details carries audio_tokens (incl. audio-in-video tokens), text_tokens, video_tokens, image_tokens, cached_tokens; plus cache_creation{ephemeral_5m_input_tokens, cache_creation_input_tokens} and cache_type (ephemeral).

Final-chunk usage example:

{"id":"chatcmpl-...","choices":[],"created":1735113344,"model":"qwen-plus","object":"chat.completion.chunk","service_tier":null,"system_fingerprint":null,"usage":{"completion_tokens":17,"prompt_tokens":22,"total_tokens":39,"completion_tokens_details":null,"prompt_tokens_details":{"audio_tokens":null,"cached_tokens":0}}}

---

Async create / poll

The OpenAI-compatible /chat/completions endpoint for Qwen text-chat is synchronous (streaming or non-streaming). There is no async create/poll job model for chat completions in this contract. (Asynchronous job-based invocation in DashScope applies to other modalities — e.g. video generation, file-based ASR — via the DashScope-native /api/v1 task endpoints, not this OpenAI-compatible chat contract.)

---

Billing / usage notes (gateway)

• usage is returned in the final chunk when stream_options.include_usage=true (the gateway’s exact-billing path injects this).
• prompt_tokens_details.cached_tokens reflects context-cache hits.
• reasoning_content (CoT) is billed as output; when preserve_thinking=true, re-fed prior reasoning is billed as input.
• Audio output (Qwen-Omni) and audio-in-video tokens surface under the respective *_tokens_details fields.
