Specifications

Provider-documented facts. “Not collected” means we have not verified that field yet, not that the feature is unsupported.

Maximum output
0 tokensSource for Maximum output (opens in a new tab)

No generated text. The API returns decision scores and probability distributions.

Output modalities
Decision scoresSource for Output modalities (opens in a new tab)

Native API result type takes precedence over generic model-card modality labels.

Reasoning
Not collected
Structured output
Not supportedSource for Structured output (opens in a new tab)

Generic structured generation is marked unsupported. The native System One API nevertheless returns structured decision results.

Streaming

Knowledge cutoff

Release date

Only this exact selector is assigned. Dated variants are not assumed equivalent.

Data retention
Standard inference prompts/responses may be retained for up to 30 days with legal/security exceptions; stateful records/files remain until deleted. Exact-selector zero-data-retention eligibility has not been established in this review.Source for Data retention (opens in a new tab)
Request mode
Synchronous TypeSafe System One API; state plus keyed questionsSource for Request mode (opens in a new tab)
Decision types
choice: single-choice classification, noul: probability of yes, score: ordinal-scale expectationSource for Decision types (opens in a new tab)
Classification options
Choice: 1–255 options; an other fallback is recommendedSource for Classification options (opens in a new tab)
Scoring levels
Parameter table: 2–10 levels; limits section: 2–255. Both recommend 3–7 clearly distinct levels.Source for Scoring levels (opens in a new tab)

Conflicting documented maxima. Do not assume scales above 10 work without confirmation.

Decisions per request
No hard question-count limit stated; 16 or fewer recommendedSource for Decisions per request (opens in a new tab)

Latency grows approximately linearly with question count.

Decision results
Choice/score probabilities and confidence; yes/no P(yes); score can be a fractional probability-weighted expectation. Responses include input token usage and latency_ms.Source for Decision results (opens in a new tab)
Published price
Limited-time free in Singapore and Beijing. No end date or future paid tariff is published.Source for Published price (opens in a new tab)
Request quotas
1,200 RPM; 2,000,000 TPMSource for Request quotas (opens in a new tab)

Caching

Caching can reuse earlier input processing. Availability, lifetime and billing depend on the endpoint. A cache hit still generates a new response.

01 / INITIAL INPUTProcess & retain

The system processes eligible input and retains reusable state.

02 / LATER REQUESTCheck available state

Reuse depends on matching input, session state and the cache policy.

03 / CACHE HITReuse & generate

Reusing state can reduce repeated work. Any charges follow the billing rules below.

What the measurements say

No benchmark observations have been added for this model. We do not turn a vendor description into a performance score.

Latency and throughput depend on the host, request size, reasoning settings and load. There is no measured speed or global usage figure in this record.

The record behind the model

Why it is included

Classification inference: this exact service release is documented as a native Alibaba model, and no corresponding weight release was found in the reviewed official Qwen and Alibaba-NLP inventories. The API documentation does not explicitly establish private checkpoint lineage. Related public Qwen3, GTE, GME and GVE weights are not assumed to implement this selector.
