Frequently Asked Questions

Which is better overall, Gemini 3 Pro or Llama 3.1 70B?

Gemini 3 Pro has the higher preference Elo in our latest snapshot (1,552). “Better” still depends on coding, price, and latency — see the table.

Which is better at coding, Gemini 3 Pro or Llama 3.1 70B?

Gemini 3 Pro leads SWE-bench at 72.4% vs 40.2%. SWE-bench is one harness, not your repo.

Which is cheaper to run in production?

Llama 3.1 70B output tokens are $0.4/1M versus $5/1M. Input prices and retry rates still move the real bill.

Which is faster, Gemini 3 Pro or Llama 3.1 70B?

Llama 3.1 70B has the lower time-to-first-token (170 ms vs 220 ms). Tokens/sec is a separate column if you care about long completions.

Which has the larger context window?

Gemini 3 Pro accepts 2M tokens versus 131k.

Can I self-host either model?

Llama 3.1 70B is marked open-weights in our catalog. The other side is a closed API. Check the provider license before you ship weights.

Are these scores from CompareLLM’s own evals?

No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.

What does preference Elo mean on this page?

Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. Gemini 3 Pro and Llama 3.1 70B Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
