Hermes 3 Llama 3.1 405b API pricing

Point the OpenAI SDK at OSMEXO and use meta/hermes-3-llama-3.1-405b

The base URL and the key are the only changes. Streaming, tool calls, structured output and vision behave as they do upstream, and every response carries the billed cost beside the list price.

from openai import OpenAI

client = OpenAI(
    base_url="https://api.osmexo.com/v1",   # was the vendor's URL
    api_key="osm-...",
)
r = client.chat.completions.create(
    model="meta/hermes-3-llama-3.1-405b",
    messages=[{"role": "user", "content": "Hello"}],
)

The same battery we run before a route goes live: tokenizer fingerprint, knowledge cutoff, hidden-prompt probe and exact-output tasks, scored 0 to 100 against the vendor’s own API. One OpenRouter key verifies any text model; a direct Meta key works too. Exit code 0 means the same model.
