Llama 3.3 70B vs Mistral Large 3

Llama 3.3 70B closed much of the gap to frontier models at the 70B-dense weight class; Mistral Large 3 pushes further on reasoning but trades away open weights in its commercial tier. Both are common picks for teams that want European data residency or fully self-hosted quality.

Verdict

Llama 3.3 70B is the more flexible option — truly self-hostable, massive fine-tune ecosystem, cheap on third-party inference. Mistral Large 3 is the stronger model on reasoning-heavy benchmarks and is the default for European enterprises that want sovereign-hosted top-tier quality. If you're in India on your own GPUs, Llama 3.3 70B is typically the right baseline; for EU regulated workloads, Mistral wins.

When to choose each

Choose Llama 3.3 70B if…

  • You want open weights and full control over the model.
  • You need broad ecosystem support — Together, Groq, Fireworks, Bedrock.
  • You plan to fine-tune or LoRA on domain data.
  • Cost per token matters and you're OK on hosted inference providers.

Choose Mistral Large 3 if…

  • You need the strongest reasoning in this weight class.
  • You need EU data residency with a French provider.
  • You're OK with closed weights for the commercial tier.
  • You need 256k context in a single call.

Frequently asked questions

Is Mistral Large 3 open-weight?

No — the current commercial tier is closed. Mistral has released open-weight models (Mistral Small, Codestral) under Apache 2.0 but Large 3 itself is API-only.

Which is better for coding?

Roughly tied. Codestral (Mistral's coding specialist) beats generic Llama 3.3 70B on code benchmarks; for general-purpose use with code, the two base models are close.

Can I run Llama 3.3 70B on my own hardware?

Yes — on 2xH100 (80GB) at bf16, or a single H100 with FP8/AWQ quantization. Consumer-grade deployment is realistic on 2x4090 with int4.
