Verified information

Overview

baidu/ernie-4.5-turbo-128k is presented as a chat model from Baidu. Start with an OpenAI-compatible call and evaluate it against your product's prompts, language, and quality criteria.

Verified routePublished endpoint

Publication confirms the /v1/chat/completions route; it does not claim features the contract has not documented.

Commercial statusReviewed price

The displayed price is NexoRouter's approved public price, not an internal cost or supplier discount.

Profile boundaryNo invented metrics

Context, tools, benchmarks, latency, TTFT, and availability appear only when they have a source and measurement window.

Delivery contract

Provider & route

baidu/ernie-4.5-turbo-128k is exposed by NexoRouter under the verified Baidu catalog mapping below. This is the delivery contract customers should use, not a promise of additional upstream routes.

Provider names describe the reviewed catalog mapping. NexoRouter does not claim multi-provider failover for a model unless it is measured and published separately.

Public billing

Pricing

Public usage pricing for this model ID. The unit changes by endpoint: not every model is billed by tokens.

Input / generation: $0.12 / 1M tokens
Cached input: $0.03 / 1M tokens
Output: $0.49 / 1M tokens

Cost estimator

Estimate a request with the current public price for this exact model ID.

Input tokensOutput tokens

Estimated total$0.00

Estimate only. Actual usage, rounding, cached tokens, media parameters, and the final billing ledger determine the charged amount.

Prices are published after commercial review. A supplier update creates a review; it never exposes supplier discounts, orders, or internal costs.

Measured, not estimated

Performance

Performance metrics are published only after NexoRouter has enough model-specific production observations and a defined measurement window.

ThroughputNot enough verified data

Tokens per second require streaming observations for this exact model ID.

End-to-end latencyNot enough verified data

A gateway response time is not the same as model inference latency, so the two are not mixed.

Time to first tokenNot enough verified data

TTFT appears only when streaming timestamps are available for a representative sample.

No benchmark or chart is synthesized from another provider. These fields will populate only from NexoRouter measurements with a sample size and time window.

NexoRouter aggregate telemetry

Activity

Privacy-preserving, aggregate model activity from NexoRouter gateway logs. No prompts, API keys, user identities, or IP addresses are exposed.

More production observations are needed

This page waits for at least 10 aggregate attempts in the current seven-day window before publishing a success rate or traffic statistic.

Success rate is computed from NexoRouter gateway outcomes for this model ID. It is not an upstream SLA, quality score, or benchmark.

OpenAI-compatible

Integration

NexoRouter exposes this model through /v1/chat/completions. Use a NexoRouter API key and retain the OpenAI-compatible base URL.

curl --fail-with-body 'https://api.nexorouter.com/v1/chat/completions' \
  -H "Authorization: Bearer $NEXOROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "baidu/ernie-4.5-turbo-128k",
  "messages": [
    {
      "role": "user",
      "content": "Hello"
    }
  ]

Sources & updates

Every profile combines NexoRouter operating data with provider documentation links. A provider link does not become a capability promise until that claim is reviewed and published.
