Gemma 3

Last updated June 19, 2026 ยท Reviewed by ToolForge Editorial

Google's open-weight model family. 1B/4B/12B/27B sizes, all commercially licensable.

โ˜… 4.6/5 ยท Google Cloud users, Vertex AI developers, hobbyists ยท Since 2024 ยท Free (open-weight, Gemma license)

What it is

Gemma 3 is the best open-weight model if you're on Google Cloud or you need a tiny-but-capable model for edge deployment.

Who it's for: Google Cloud users, Vertex AI developers, hobbyists.

Key features

4 sizes 1B โ†’ 27B params

Four sizes cover everything from a Raspberry Pi (1B) to a single H100 (27B). Pick the model that fits your hardware and budget.

128K 128K context

All sizes support 128K tokens โ€” far longer than Llama 3 (8K) or Mistral Small (32K).

Multimodal Vision in 4B+

4B, 12B, and 27B sizes accept images natively. Document understanding, OCR, chart parsing โ€” all in one model.

Vertex AI Google Cloud native

One-click deploy on Vertex AI, with managed scaling and enterprise SLAs. Best-in-class if you're already on GCP.

The honest take

โœ“ What works

  • Four sizes for every hardware budget
  • 128K context across the entire lineup
  • Native vision in 4B+ models
  • Tightest integration with Google Cloud / Vertex AI
  • Gemma license allows commercial use (with restrictions)

โœ— What doesn't

  • Gemma license has use-case restrictions (no weapons, no biometric surveillance)
  • Smaller fine-tuning community than Llama
  • Performance trails Llama 4 70B and Qwen 3 72B on hard reasoning
  • Vertex AI pricing is opaque โ€” calculator is required

Verdict

Gemma 3 is the best open-weight model if you're on Google Cloud or you need a tiny-but-capable model for edge deployment. The 1B and 4B sizes are unmatched at their weight. For pure on-prem reasoning, Llama 4 or DeepSeek R1 are smarter, but Gemma 3 wins on ecosystem polish.
