Deep dive
The capability footprint differs most on function calling: Together AI - Gemma 3n-e4B and tool use: Together AI - Gemma 3n-e4B. Both models share structured outputs, 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, Together AI - Gemma 3n-e4B lists $0.02/1M input and $0.04/1M output tokens, while Llama 2 13B Chat lists $0.1/1M input and $0.5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI - Gemma 3n-e4B lower by about $0.19 per million blended tokens. Availability is 1 providers versus 12, so concentration risk also matters.
Choose Together AI - Gemma 3n-e4B when long-context analysis, larger context windows, and lower input-token cost are central to the workload. Choose Llama 2 13B Chat when provider fit 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.
