Nous: Hermes 3 70B Instruct

text->text

The 2024 70B Llama that defined the open-weights chat baseline before Llama 3.3. Still common where hosts haven't upgraded yet.

Nous: Hermes 3 70B Instruct is a efficient AI model from nousresearch. It costs $0.700 per million input tokens and $0.700 per million output tokens (blended $0.700/M), with a 131K-token context window.

Profile inherited from upstream Llama 3.1 70B (Hermes 3 base) ↗ — this is a hosted variant of the same open-weights model.
