Specifications

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

Input modalities
Text, Image, VideoSource for Input modalities (opens in a new tab)

The vision guide explicitly names this preview selector for audio understanding within video. This is not standalone audio input/output support.

Tool calling
SupportedSource for Tool calling (opens in a new tab)

Explicitly listed in the China tool-calling support range. Do not infer the international support matrix.

Structured output
Not collected
Streaming
SupportedSource for Streaming (opens in a new tab)

The listed models use the Chat Completions API with SSE.

Maximum thinking tokens
60KSource for Maximum thinking tokens (opens in a new tab)

max_tokens covers reasoning plus final output; ERNIE thinking models do not support thinking_budget.

Reasoning controls
enable_thinking defaults to true for this selector and can be disabled.Source for Reasoning controls (opens in a new tab)
Scheduled retirement
China endpoint: 2026-10-29. Scheduled after this snapshot.Source for Scheduled retirement (opens in a new tab)
Snapshots and aliases
ernie-5.0-thinking-preview, ernie-5.0-thinking-latestSource for Snapshots and aliases (opens in a new tab)

Latest is retained as a rolling access selector, not counted as an additional fixed checkpoint. The current checkpoint equality is not independently established.

Access & pricing

Prices belong to an endpoint and billing tier. A provider listing does not guarantee access for every account or region.

API model ID
ernie-5.0-thinking-preview
Access
Qianfan account and appropriate API key required. Documented access has not been verified with a paid inference call.
Regions
China platform; a hostname alone does not establish data residency.
API endpoint URL
POST https://qianfan.baidubce.com/v2/chat/completionsSource for API endpoint URL (opens in a new tab)
Request limits
RPM = 60 TPM = 150000Source for Request limits (opens in a new tab)

Published default quotas, not a universal service guarantee.

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

Inferred for this exact named Baidu commercial model from native documentation and comparison with Baidu’s public model repositories. No weights for this exact service were found in the reviewed inventory. Public ERNIE 4.5 and ERNIE Image releases are excluded, and ambiguous Turbo mappings remain under review. This is not proof that all Baidu models are closed.
