Hermes 4 – Llama-3.1 70B (Reasoning)
Analysis Summary
Hermes 4, based on Llama 3.1 70B in reasoning mode, is offered by Nous Research. Its supplied results show strong math and coding capability, while instruction following is more moderate and the long-context result is limited. Listed pricing is $0.13 per million input tokens and $0.40 per million output tokens.
This is a reasonable candidate for cost-conscious coding and quantitative reasoning trials where the work can be verified. The evidence does not support treating it as a long-document specialist or a reliable autonomous agent, and client-facing written output should be reviewed for quality and instruction adherence.
Its listed price supports testing at higher volumes than the 405B variant. Adopt for a specific workload only after comparing its accuracy and review burden with alternatives.
