Value for money
Llama 3.1 70B is open-weight and can be self-hosted, which can dramatically lower cost at scale versus a per-token API.
Llama 3.1 70B vs Nova Pro: which should you choose?
Llama 3.1 70B — Meta large language model (2024) with a 128K-token context window and an MMLU score of 86.0%, released with open weights.
Nova Pro — Amazon large language model (2024) with a 300K-token context window and an MMLU score of 85.9%.
Llama 3.1 70B vs Nova Pro: Llama 3.1 70B scores higher on the MMLU benchmark. Llama 3.1 70B leads general capability (MMLU 86.0% vs 85.9%). Nova Pro offers the larger context window, useful for long documents and codebases.
Capability and reasoning
On MMLU — a 57-subject benchmark of general knowledge and reasoning — the Llama 3.1 70B scores 86.0% versus 85.9%. MMLU is a useful proxy for raw knowledge but does not capture instruction-following, coding, tool use, latency or safety, so treat it as one signal among several.
Context window
The Nova Pro handles up to 300K tokens per request, which sets how much documentation, transcript or code it can reason over at once — decisive for retrieval-augmented and long-document workflows.
Pricing and access
Llama 3.1 70B is open weights and Nova Pro is proprietary api. Proprietary models bill per token via API; open-weight models can be self-hosted, trading per-call cost for infrastructure you manage. For production, weigh throughput, rate limits and data-residency needs alongside headline price.
The verdict
Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Large language models are compared on the MMLU benchmark (a widely-cited 57-subject test of general knowledge and reasoning, reported as a percentage), maximum context window, and published API pricing per million input and output tokens. Open-weight models can also be self-hosted. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit.
