Getting started
Call Qwen 3 Max Thinking through AI Gateway with the AI SDK generateText and streamText functions, or through the OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages APIs by changing the base URL. AI Gateway authenticates the request and routes it to an available provider.
Install the AI SDK (pnpm add ai dotenv), create an API key from the API Keys page, and set it as AI_GATEWAY_API_KEY in your environment. Full setup is covered in the text generation quickstart.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'alibaba/qwen3-max-thinking', prompt: 'Why is the sky blue?', });
console.log(result.text);}
main().catch(console.error);Top-level parameters
The same Qwen 3 Max Thinking request in each API format AI Gateway supports.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'alibaba/qwen3-max-thinking', system: 'You are a concise technical assistant.', prompt: 'Summarize the tradeoffs between static generation and SSR.', maxOutputTokens: 1024, });
console.log(result.text);}
main().catch(console.error);Standard parameters like prompt, messages, temperature, and tools work as documented in the AI SDK docs. These are the parameters with model-specific behavior.
| Parameter | Type | Required | Description |
|---|---|---|---|
model | string | Yes | Model ID in the form creator/model, e.g. alibaba/qwen3-max-thinking. AI Gateway routes the request to an available provider. |
maxOutputTokens | number | No | Hard cap on generated tokens. Qwen 3 Max Thinking supports up to 65,536 output tokens. Reasoning tokens count toward this limit. |
reasoning | 'provider-default' | 'none' | 'minimal' | 'low' | 'medium' | 'high' | 'xhigh' | No | Provider-agnostic reasoning effort, available in AI SDK 7 or later. Maps to the provider’s native reasoning configuration; reasoning settings under providerOptions take precedence when both are set. See the Reasoning section below. |
providerOptions | Record<string, JSONValue> | No | AI Gateway routing options under gateway, plus any provider-native options under the provider’s own namespace — see the table below. |
Input limits
| Input | Formats | Sources | Max count | Max size | Limits |

Provider options
Set AI Gateway routing options under providerOptions.gateway. For provider-specific options, pass them under the provider’s namespace as documented by the AI SDK.
Learn more in the AI SDK alibaba provider docs.
import { generateText } from 'ai';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'alibaba/qwen3-max-thinking', prompt: 'Why is the sky blue?', providerOptions: { gateway: { only: ['alibaba'], }, }, });
console.log(result.text);}
main().catch(console.error);These AI Gateway routing options apply to every model. Provider-specific options pass through under the provider’s own namespace (for example providerOptions.anthropic) exactly as documented by the AI SDK.
| Parameter | Type | Required | Description |
|---|---|---|---|
providerOptions.gateway.only | string[] | No | Restrict routing to these provider slugs. Requests fail over only within the listed providers. |
providerOptions.gateway.order | string[] | No | Preferred provider order. Listed providers are tried first; unlisted providers remain available as fallbacks. |
providerOptions.gateway.sort | 'cost' | 'ttft' | 'tps' | No | Rank candidate providers by price, time to first token, or tokens per second instead of the default routing order. |
providerOptions.gateway.zeroDataRetention | boolean | No | Route only to providers with a zero-data-retention policy for this model. |
Routing across providers
AI Gateway serves the same model through multiple providers and fails over automatically. order expresses a preference while keeping every provider eligible; only is a hard allowlist — if none of the listed providers are available the request fails instead of falling back.
Options under a provider's own namespace (for example providerOptions.anthropic) are forwarded to that provider with the request. Providers ignore option namespaces that don't apply to them, so it is safe to set provider options alongside gateway routing options.
Reasoning
AI Gateway bridges reasoning across every API format. The AI SDK exposes a provider-agnostic top-level reasoning level (none, minimal, low, medium, high, or xhigh); the Chat Completions and Responses formats take the same effort under reasoning.effort; and the Anthropic Messages format uses a native thinking token budget. Whichever you send, the gateway maps it to the target model’s native configuration, converting between effort levels and token budgets as needed. Reasoning-related settings under providerOptions take full precedence over the top-level reasoning value and are never merged. Reasoning tokens typically count toward your output-token usage, though how they’re reported and billed varies by provider.
Learn more in the AI Gateway reasoning guide.

Expose tools the model can call. Define each tool’s inputs with a Zod schema.
import { generateText, tool } from 'ai';import { z } from 'zod';import 'dotenv/config';
async function main() { const result = await generateText({ model: 'alibaba/qwen3-max-thinking', prompt: 'What is the weather in San Francisco?', tools: { getWeather: tool({ description: 'Get the current weather for a location', inputSchema: z.object({ location: z.string() }), execute: async ({ location }) => ({ location, temperatureC: 18 }), }), }, });

Qwen 3 Max Thinking, released on January 23, 2026, extends the Qwen3-Max architecture with a dedicated extended reasoning mode and integrated autonomous tool use. When Qwen 3 Max Thinking encounters a question that exceeds its internal knowledge or requires computation, it independently decides whether to trigger its Search tool (for current information), Memory tool (for cross-turn context persistence), or Code Interpreter (for numerical verification and data processing), without you needing to specify which tool applies.
This autonomous tool selection is a meaningful architectural distinction. Rather than exposing tool invocation as an explicit user-facing control, Qwen 3 Max Thinking treats it as an internal reasoning step, making the interaction feel more like working with a capable assistant that knows when to check its work. The design is intended to reduce hallucination risk on factual queries by defaulting to retrieval when confidence is low, and to improve numerical accuracy by routing computations through an interpreter.
Qwen 3 Max Thinking's thinking mode exposes its reasoning chain before delivering a final answer, providing transparency into multi-step problem decomposition. On Humanity's Last Exam, a benchmark of approximately 3,000 graduate-level questions spanning mathematics, science, and engineering, Qwen 3 Max Thinking with search enabled scored 49.8, competitive with other models on the same benchmark in Alibaba Cloud's published comparisons. You can access Qwen 3 Max Thinking through AI SDK, Chat Completions API, Responses API, Messages API, or other API formats, from TypeScript or Python.
Copy link to headingWhat To Consider When Choosing a Provider
- Configuration: Thinking-mode responses can be substantially longer than standard completions, factor in output token volume when estimating per-request cost across providers.
- Zero Data Retention: Zero Data Retention is available for this model. It is offered on a per-provider and model basis. See the documentation for details.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
Copy link to headingWhen to Use Qwen 3 Max Thinking
Best for
- STEM and engineering questions: Hard scientific, mathematical, or engineering problems that benefit from visible chain-of-thought reasoning
- Search-grounded research assistance: Workflows where real-time search reduces the risk of stale or invented information
- Self-correcting numerical agents: Automated agents that route calculations through a code interpreter to verify outputs
- Multi-turn personalized conversations: Extended sessions where the model must remember and adapt to user preferences
- Autonomous tool orchestration: Complex pipelines where the model decides which tool to invoke without explicit user prompting
Consider alternatives when
- Tight token budgets: Thinking-mode responses consume substantially more output tokens than direct-answer models
- Low-latency requirements: Fast completions matter more than extended reasoning, which becomes unnecessary overhead
- Deterministic tool control: Autonomous tool selection may not align with strictly orchestrated pipelines that need manual control
- Creative or conversational tasks: Step-by-step reasoning adds friction rather than value in these contexts
Copy link to headingConclusion
Qwen 3 Max Thinking is built for situations where getting the right answer matters more than getting it quickly: graduate-level problem solving, real-time research synthesis, and agentic pipelines that need a model capable of recognizing its own knowledge gaps. The combination of autonomous tool orchestration and transparent reasoning chains fits complex, open-ended inference tasks.
Copy link to headingFrequently Asked Questions
What tools does Qwen 3 Max Thinking invoke autonomously?
The model has three integrated tools: Search (for retrieving current information), Memory (for tracking user preferences and context across turns), and Code Interpreter (for executing code to verify or compute results). It selects among them without user prompting.
How does the thinking mode differ from standard completion mode?
In thinking mode, the model generates an extended internal reasoning trace before producing its final answer. This trace is visible in the response and reflects multi-step problem decomposition, which improves accuracy on hard reasoning tasks at the cost of more output tokens.
What did the model score on Humanity's Last Exam?
With its Search tool enabled, Qwen 3 Max Thinking scored 49.8 on Humanity's Last Exam, a benchmark of ~3,000 graduate-level questions across math, science, and engineering.
Which SDKs are compatible with this model via AI Gateway?
You can access Qwen 3 Max Thinking through AI SDK, Chat Completions API, Responses API, Messages API, or other API formats, from TypeScript or Python.
Does autonomous tool use mean I can't control when tools fire?
You can't manually control which tools fire. The model selects tools as an internal reasoning step. If your application requires deterministic, manually orchestrated tool calls, the non-thinking Qwen3-Max variant with explicit function-calling schemas is a better fit.
How does the Search tool reduce hallucinations?
When Qwen 3 Max Thinking's internal confidence on a factual claim is low, it automatically triggers a search query to retrieve current information rather than generating an answer from its internal knowledge alone, which reduces the frequency of confidently stated incorrect facts.
What is the token cost model for thinking-mode responses?
Thinking-mode completions generate reasoning traces that can be substantially longer than direct answers. Output tokens from both the reasoning chain and the final response are billed.
