Deep dive
The capability footprint differs most on vision: Gemma 4 12B, multimodal input: Gemma 4 12B, reasoning mode: Gemma 4 12B, function calling: Gemma 4 12B, and tool use: Gemma 4 12B. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
Pricing coverage is uneven: Gemma 3n 2B (free) has no token price sourced yet and Gemma 4 12B has no token price sourced yet. Provider availability is 1 tracked routes versus 2. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Gemma 3n 2B (free) when provider fit are central to the workload. Choose Gemma 4 12B when reasoning depth, larger context windows, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
FAQ
Which has a larger context window, Gemma 3n 2B (free) or Gemma 4 12B?
Gemma 4 12B supports 256k tokens, while Gemma 3n 2B (free) supports 8k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
Is Gemma 3n 2B (free) or Gemma 4 12B open source?
Gemma 3n 2B (free) is listed under Proprietary. Gemma 4 12B is listed under Apache 2.0. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Gemma 3n 2B (free) or Gemma 4 12B?
Gemma 4 12B has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for multimodal input, Gemma 3n 2B (free) or Gemma 4 12B?
Gemma 4 12B has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for reasoning mode, Gemma 3n 2B (free) or Gemma 4 12B?
Gemma 4 12B has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Where can I run Gemma 3n 2B (free) and Gemma 4 12B?
Gemma 3n 2B (free) is available on NVIDIA NIM. Gemma 4 12B is available on Hugging Face Inference Endpoints and Kaggle Models. Provider coverage can affect latency, region availability, compliance posture, and fallback options.
