How to Use
Download from Hugging Face or run via Ollama (`ollama run gemma2`). Multiple sizes available from 2B to 27B.
Pros
- Open source from Google — well-documented and actively maintained
- Very efficient for its size — strong quality-per-parameter ratio
- Runs on consumer hardware — 2B variant works even on phones
- Multiple sizes (2B/9B/27B) for different hardware constraints
Cons
- Small context window (8K) — very limited for document processing
- Weaker than larger models on complex tasks
- Text-only — no vision or multimodal capabilities
- Superseded by Gemma 3 for most use cases
What to Use It For
Perfect For
On-device AI on constrained hardware
2B variant runs on phones and edge devices with minimal resources
Learning and experimenting with LLMs
Well-documented, easy to run locally, and backed by Google research
Good For
Private local inference
All data stays on your machine — complete privacy guaranteed
Not Recommended
Long document processing
8K context is far too short for most real-world document tasks
Try instead: Gemini 2.5 Pro
Complex reasoning
Small model size limits reasoning depth significantly
Try instead: o3
Do Not Use For
Production enterprise chatbots
Quality gap with frontier models is too large for customer-facing applications
Try instead: Claude Sonnet 4
Multimodal tasks
Text-only model — cannot process images, audio, or video
Try instead: GPT-4o
