Architecture, strengths and use cases

Gemma 3 27B IT is an official self-hostable Google release in the Gemma General track. It uses Dense Transformer, carries 27B, supports a verified context window of 128,000 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.

Gemma 3 27B IT uses Dense Transformer with 27B. The stored architecture profile records 64 layers, hidden width 8192, 64 attention heads and a 128,000 token context ceiling where the official configuration publishes those fields.

License and self-hosting considerations

The full 27B 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.
