How are Intelligence, Speed & Cost bucketed?
Intelligence and Speed buckets are percentile ranks on
Artificial Analysis. Cost buckets are fixed dollar
thresholds keyed off output-token price ($/M out).

Percentile boundaries are computed across every model in the tree that reports the underlying benchmark for each capability.
What it feels like
- 675B sparse MoE / ~41B active — Mistral's biggest model and first with 256K context
- Beats Kimi-K2 and DeepSeek-3.1 on Mistral's headline benchmarks; 1418 LMSYS Elo at release
- MMLU 88.7% and HumanEval 92.3% — frontier-tier on coding, top of the open-weight pack
- Solid but not best-in-class on hardest math contests — 'more than adequate' for business analytics
- Cheap: $0.50/M in, $1.50/M out — among the most affordable frontier-tier APIs
- Slower than average at ~50 tok/s — pick this for quality/price, not for chat speed
Best use cases
- Vision + text workflows that benefit from iteration (image input is first-class)
- Long-document analysis up to 256K tokens at affordable open-weight pricing
- European customers needing GDPR-friendly hosting and EU-anchored vendor
- Self-hosted production once weights ship — TechCrunch confirmed open-weight release
Tools to try
Not ideal for
- Latency-sensitive interactive chat — throughput is below average
- Hardest reasoning leaderboards — Claude Opus 4.5, GPT-5, DeepSeek V4 score higher
- Pure-text deployments where smaller Mistral models would be cheaper
