Deep dive

The capability footprint differs most on structured outputs: Gemma 3 12B (free). 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.

For cost, Gemma 3 12B (free) lists $0.04/1M input and $0.13/1M output tokens, while Mistral NeMo (2407) lists $0.02/1M input and $0.03/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral NeMo (2407) lower by about $0.04 per million blended tokens. Availability is 3 providers versus 5, so concentration risk also matters.

Choose Gemma 3 12B (free) when provider fit are central to the workload. Choose Mistral NeMo (2407) when long-context analysis, larger context windows, and lower input-token cost 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. It also helps separate model capability from provider packaging, which can change cost and latency.
