About Hermes 4 405B
Hermes 4 405B is a 405B hybrid-reasoning chat model from Nous Research with a 128K-token context window, known for steerability and low refusal rates. Muapi exposes it through a single REST endpoint with async polling and Server-Sent Events streaming, so you can drop it into chat apps, agents and workflows without hosting GPUs. It is best suited to steerable general chat, reasoning and agents. Pricing is pay-per-token at $0.6/M input tokens and $2.4/M output tokens, with no subscription. See also [Venice Abliterated](/playground/venice-abliterated). Browse the full lineup on the [Low-Refusal LLM API](/low-refusal-llm-api) page or the [Abliterated LLM API](/abliterated-llm-api) hub and the [Character Chat LLM API](/character-chat-llm-api) hub. It is tuned to refuse less often than mainstream assistants, but it does not guarantee unrestricted output, and you remain responsible for complying with applicable laws and the Muapi terms of use.
