Nous: Hermes 4 70B

Nous: Hermes 4 70B is a text-only model from Nous Research with a 131,072-token context window and built-in reasoning support. It does not support tool use or structured output, so it is best suited for long-form text tasks where extended reasoning over large documents matters more than function calling or schema-constrained responses. There is no stated cap on completion length based on available data. For comparison purposes, the model sits at $0.13 per million input tokens and $0.40 per million output tokens, which is a relatively low price tier and may appeal to teams running high-volume reasoning workloads on a budget. The significant caveat is that no independent benchmark coverage exists yet, so there is no scored evidence to confirm how it performs against alternatives. Buyers willing to run their own evaluations may find the price worth testing, but those needing verified quality signals before committing should wait for benchmark data to emerge.
