Capability profile

Operator guidance

Route here for open-weights reasoning with high steerability at low cost — the Hermes line's traditional niche. For frontier reasoning accuracy, a larger open model (Qwen 3 235B, DeepSeek V4) or a proprietary reasoning model will outperform it. The Meta Llama 3 Community License (below) is more restrictive than the Apache-2.0 of most other open models in this registry — check it if licensing is a constraint.

Use cases

• Open-weights reasoning at 70B scale where steerability and low refusal rates matter (agent backends, structured extraction, roleplay/persona work)
• Self-hosted deployment where a togglable reasoning mode is wanted without running a frontier-size model
• Tasks needing strong math/logic at open-model cost

Limitations

• Meta Llama 3 Community License — a derivative-model license with use restrictions, not a fully-open Apache/MIT license
• Benchmark figures are from Nous's own technical report; no independent third-party leaderboard reproduction found
• No first-party hosted API — served here via OpenRouter (single upstream provider)
• Reasoning-mode benchmarks are substantially higher than non-reasoning mode; a fair comparison depends on which mode the caller uses
