Gemma 3

Google’s Multimodal Open AI Model Family (1B–27B + Variants)

What is Gemma 3?

‍Gemma 3 is Google DeepMind’s third-generation family of open-weight AI models, ranging from 1B to 27B parameters. Designed for both developers and researchers, these models deliver best-in-class text generation, advanced image understanding, and massive 128K-token context, making Gemma 3 a strong alternative to proprietary LLMs. Unlike previous versions, Gemma 3 supports full multimodal input (text + images) from 4B upwards and can run efficiently on a single GPU or TPU, even the flagship 27B variant rivals much larger models in real-world tasks.

Key Features of Gemma 3

Four Model Sizes

1B (text only, 32K tokens)
