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
- Refresh of V3 with reasoning capabilities folded in.
- 671B-param MoE (37B active per token) — the open-weights model that finally matched GPT-4 / Claude 3.5 Sonnet quality
- 82.6% HumanEval (coding) and 90.2% MATH-500 — outperformed GPT-4o, Claude 3.5 Sonnet, and Llama 3 on each
- Trained for $5.576M on 2.788M H800 GPU hours — 1/100th of comparable proprietary training budgets
Best use cases
- Self-hosted frontier-quality LLM for orgs that can't use proprietary APIs
- Math, coding, and general knowledge benchmarks at open-source price
- Fine-tuning and distillation into smaller production models
Tools to try
Not ideal for
- Edge / single-GPU deployments — the MoE size is large despite low active params
- Multimodal use cases — text-only
