Architecture, strengths and use cases
ERNIE 4.5 300B-A47B is an official self-hostable Baidu release in the ERNIE General track. It uses Ernie4_5_MoeForCausalLM, carries 300B / 47B MoE, supports a verified context window of 131,072 tokens, and exposes only source-certified checkpoints and runtime combinations. Its release, license and deployment facts are tied to the official repository revision rather than inferred from the family name.
ERNIE 4.5 300B-A47B uses Ernie4_5_MoeForCausalLM with 300B / 47B MoE. The stored architecture profile records 54 layers, hidden width 8192, 64 attention heads and a 131,072 token context ceiling where the official configuration publishes those fields.

Certified checkpoints and quantizations
Only exact, source-certified variants attached to this release are shown.
Recommended hardware
Use only the listed fastdeploy runtime configuration with the exact checkpoint precision. The recommendation engine checks weight memory, KV cache, runtime overhead, safety headroom, GPU architecture and topology before ranking rentable and reference hardware.
Estimated weight memory575.56 GB
KV cache1.69 GB
Runtime overhead146.38 GB
Total with safety margin897.3 GB
Technically compatible reference sizing
No current FusionPointAI inventory passes every runtime, architecture, topology and memory gate for this exact checkpoint. Use the estimator for global compatible hardware.
License and self-hosting considerations
The full 300B resident weight set must fit across the selected GPUs. Context and concurrency add KV-cache memory; MoE active parameters do not replace resident-weight memory.
ERNIE 4.5 300B-A47B is published under apache-2.0. The release-scoped official license link and verification date are retained with the catalogue record.
Commercial Use Allowed. The official license permits commercial use; its obligations still apply.
