Run ERNIE-4.5-300B-A47B with SiliconFlow's API

The Baidu ERNIE team has announced the release of its ERNIE-4.5-300B-A47B, a powerful open-source large language model now available on the SiliconFlow platform.

Built on a Mixture-of-Experts (MoE) architecture, the model features 300B total parameters with 47B activated parameters per token. It delivers strong performance across multiple domains—including mathematical reasoning, accurate computation, and code generation—making it particularly well-suited for applications in mathematical computing and programming-related tasks.

SiliconFlow offers:

• Inference Acceleration: Optimized for lower latency and higher throughput.

• Extended Context: 128K token context window.

• Cost-Optimized Pricing: $0.29/M tokens(input) and $1.15/M tokens (output).

Technical Highlights

ERNIE-4.5-300B-A47B's strong capabilities in instruction following and knowledge utilization in single-turn, multi-turn, and multilingual scenarios may be attributed to unified rewarding system, which incorporates carefully designed reward mechanisms to guide the model in better interpreting and adhering to diverse user instructions and internal knowledge.
