Architecture, strengths and use cases

InternLM3 8B is an official self-hostable Shanghai AI Laboratory release in the InternLM General track. It uses Dense Transformer, carries 8B, 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.

InternLM3 8B uses Dense Transformer with 8B. The stored architecture profile records 64 layers, hidden width 8192, 64 attention heads and a 131,072 token context ceiling where the official configuration publishes those fields.

License and self-hosting considerations

The full 8B 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.
