ERNIE 5.0

ERNIE 5.0 Thinking is the reasoning‑optimized line of the model, designed specifically for deep analysis, complex problem solving, and long‑context workloads.

What Is ERNIE 5.0?

ERNIE 5.0 is a large-scale foundation model with trillions of parameters designed for high‑accuracy language and multimodal understanding. It is developed by Baidu and positions itself among the strongest global models in reasoning, instruction following, and creative tasks.​

  • ERNIE 5.0 supports text, image, audio, and video inputs and outputs as a native capability, not as an add‑on.​
  • Benchmarks show performance comparable to leading international systems across language and multimodal tasks.

ERNIE 5.0 API Versions & Pricing

ERNIE 5.0 offers two main APIs, each tailored for specific user needs:

ERNIE 5.0 Thinking Preview
  • Pricing: $0.0936 per input / $0.3718 per output
  • Optimized for experimentation and lightweight reasoning tasks
  • Ideal for developers and businesses exploring ERNIE 5.0 capabilities before full deployment
ERNIE 5.0 Thinking Latest
  • Pricing: Starting at $1.2298 per input / $2.0449 per output
