Deep dive
On shared benchmark coverage, HumanEval has Gemma 2 9B at 58.4 and Llama 3.1 70B Instruct at 84.1, with Llama 3.1 70B Instruct ahead by 25.7 points; Massive Multitask Language Understanding has Gemma 2 9B at 71.5 and Llama 3.1 70B Instruct at 86, with Llama 3.1 70B Instruct ahead by 14.5 points. The largest visible gap is 25.7 points on HumanEval, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint is close: both models cover structured outputs. That makes context budget, benchmark fit, and provider maturity more important than a simple checklist. If your application depends on one integration detail, verify it against the provider route you plan to use, not just the base model listing.
For cost, Gemma 2 9B lists $0.06/1M input and $0.18/1M output tokens, while Llama 3.1 70B Instruct lists $0.4/1M input and $0.4/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemma 2 9B lower by about $0.3 per million blended tokens. Availability is 3 providers versus 11, so concentration risk also matters.
Choose Gemma 2 9B when provider fit and lower input-token cost are central to the workload. Choose Llama 3.1 70B Instruct when long-context analysis, 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.
