Independent and unofficial: Qwen-AI.chat is not operated by, affiliated with, or endorsed by Alibaba Cloud, QwenCloud, Alibaba Group, or the Qwen team. The specifications and prices below were checked against first-party pages on the date above. This site did not complete an authenticated qwen3.8-max inference request during this update, so no API example or model result on this page is described as independently live tested.
Qwen3.8 Max is QwenCloud’s current production flagship under the exact model ID qwen3.8-max. QwenCloud announced it on August 3, 2026 as a native vision-language Mixture-of-Experts model with 2.4 trillion total parameters, hybrid thinking enabled by default, and a 1M-token context category.
The production ID is not the same as qwen3.8-max-preview. Both exact strings remain present in QwenCloud Token Plan allowlists at this verification cutoff. The preview remains a separate, changeable preview route; it must not be described as retired or silently substituted in an existing configuration.
Hosted production access does not establish downloadable weights. No official public Qwen3.8 Max checkpoint, repository, or model-specific open-weight license was found during this review.

Production qwen3.8-max versus qwen3.8-max-preview
| Exact ID | Lifecycle and access | Safe interpretation |
|---|---|---|
qwen3.8-max |
Production flagship released August 3, 2026; listed by QwenCloud Marketplace, the current model selector, the Responses reference, and both Token Plan allowlists | Use this exact ID when the selected QwenCloud route and account expose the production model. Confirm the key, base URL, protocol, and region together. |
qwen3.8-max-preview |
Separate preview ID still listed by Token Plan Individual and Team | Keep the preview label. Its behavior and promotions can change, and QwenCloud says it may later be taken offline or replaced. Do not call it retired unless an official lifecycle notice says so. |
The existence of a production model does not prove that every old preview configuration migrated automatically. Record the exact ID returned by the service and keep a tested fallback before changing a production integration.
Confirmed capabilities and service limits
QwenCloud describes Qwen3.8 Max as a native vision-language model. Its Marketplace accepts text, image, and video input and returns text. This does not mean that the model generates images, video, or audio; those outputs require separate models or platform services.
The current Marketplace publishes the following service limits for qwen3.8-max:
- Context: 1M tokens.
- Maximum input: 991K tokens.
- Maximum input with thinking: 983K tokens.
- Maximum output: 131K tokens.
- Maximum output with thinking: 131K tokens.
- Maximum reasoning: 262K tokens.
These are provider-published ceilings, not a recommendation to fill the window. Leave room for reasoning, tool results, and final output. Long-context accuracy and latency must be tested on the real workload; a maximum accepted length is not proof that every fact inside a one-million-token prompt will be recalled reliably.
QwenCloud’s current selector lists Function Calling, built-in tools, and structured output for production qwen3.8-max. The Marketplace lists Responses built-in tools including web search, web extraction, code interpreter, text-to-image search, and reverse-image search. Tool availability can depend on the protocol and account. A model proposes tool calls; the surrounding application must validate arguments, enforce authorization, run the tool, and validate the returned data.
Qwen3.8 Max pricing
QwenCloud’s model-specific Marketplace displayed the following public list prices on August 3, 2026. Every amount is in US dollars per 1 million tokens:
| Billing item | Public list price |
|---|---|
| Input | $2.00 |
| Output | $6.00 |
| Implicit-cache input | $0.25 |
| Explicit-cache creation | $2.50 |
| Explicit-cache read | $0.17 |
Example: 100,000 uncached input tokens and 20,000 output tokens would cost (0.1 × $2) + (0.02 × $6) = $0.32, before tool fees, taxes, promotions, retries, or other infrastructure costs.
These are QwenCloud Marketplace prices, not a universal Alibaba Cloud Model Studio regional quote. Do not copy them into another provider’s price table without confirming the exact model, region, deployment scope, key, and billing page. See the Qwen API pricing guide for route-separated pricing and cost formulas.
API status and verification boundary
QwenCloud’s current OpenAI-compatible Responses reference explicitly includes qwen3.8-max and qwen3.8-max-preview. Its model selector and Marketplace also publish production capabilities and a vendor request example. Some feature guides and generic Chat examples still use Qwen3.7 IDs or family-level wording, so protocol support must be checked against the exact current reference rather than inferred from the generation name.
No authenticated production request was completed for this page update. Before publishing a code block as tested, run one small request with:
- the exact
qwen3.8-maxID; - the QwenCloud PAYG key for the selected workspace;
- the matching base URL and region;
- the intended protocol, such as Responses, Chat Completions, or DashScope multimodal;
- a non-sensitive text prompt first, followed separately by any required image, video, Function Calling, structured-output, or built-in-tool test.
Record the date, endpoint family, region, HTTP status, request ID, returned model ID, usage fields, settings, and final output without exposing the API key. Until that succeeds, describe code as documentation-based, not independently executed. Continue with the Qwen API guide for route and credential boundaries.
Token Plan is not a backend API plan
Token Plan Individual and Team currently allowlist both qwen3.8-max and qwen3.8-max-preview, but the plan has a decisive use restriction. QwenCloud limits Token Plan to interactive use inside compatible programming and agent tools. Automated scripts, custom application backends, and non-interactive batch processing are prohibited and may lead to suspension or API-key revocation.
Use QwenCloud pay as you go for an application or API integration. Token Plan uses a dedicated key and Token Plan base URL; its credentials must not be mixed with QwenCloud PAYG, Coding Plan, or Alibaba Cloud Model Studio endpoints. Credits and temporary promotions are not a dollar-per-million-token PAYG rate.
Is Qwen3.8 Max downloadable or self-hostable?
Not from an official public checkpoint verified at this cutoff. qwen3.8-max is a hosted service ID. A production API release does not establish that its weights, tokenizer files, training recipe, or license are public.
For local deployment, select an exact official open-weight checkpoint and read its own model card and license. See the Qwen download and local setup guide and the Qwen cloud hosting guide for the hosted-versus-open distinction.
Qwen3.8 Max versus Qwen3.7 Max
QwenCloud now recommends qwen3.8-max for its highest-capability tier. qwen3.7-max is an older hosted Max entry that remains listed where supported. No reviewed lifecycle notice assigns Qwen3.7 Max a retirement date, so it must not be called retired.
Evaluate both only on the same route and workload. Record model IDs, reasoning settings, input modalities, context lengths, tools, latency, token usage, errors, and success criteria. Vendor statements about improved capability over Qwen3.7 are not a substitute for independent results.
Frequently asked questions
What is the current Qwen3.8 Max model ID?
The production ID is qwen3.8-max. The separate qwen3.8-max-preview ID remains in current Token Plan allowlists.
Is Qwen3.8 Max fully released?
Yes as a hosted production QwenCloud model. QwenCloud announced it on August 3, 2026 and calls it the current flagship. This does not mean that public model weights were released.
Is Qwen3.8 Max the same as Qwen3-8B?
No. “3.8” is the generation/version label in Qwen3.8 Max. Qwen3-8B is a separate, earlier checkpoint whose “8B” denotes its approximate parameter scale.
Does Qwen3.8 Max support images and video?
QwenCloud’s Marketplace lists text, image, and video input with text output for the production route. It does not list image, video, or audio generation as outputs.
What does Qwen3.8 Max cost?
The QwenCloud Marketplace list price checked on August 3, 2026 was $2 per 1M input tokens and $6 per 1M output tokens, with separate cache rates. Confirm the live page and account console before budgeting.
Can Token Plan power my application’s backend?
No. Current Token Plan terms limit it to interactive use in compatible programming and agent tools. QwenCloud directs application and API integrations to pay as you go.
Is Qwen3.8 Max open source?
No public Qwen3.8 Max checkpoint and model-specific license were verified. Hosted API access is not proof of open weights.
