Hermes and OpenClaw

Same gateway, different traffic shapes. You still pick pin vs Auto.

Hermes Agents logo

Hermes Agents

Research · multi-step · codegen

Tool loops stay on lean models. Hard research or codegen steps can take Sonnet. cost_usd comes back on every call.

OpenClaw Agents logo

OpenClaw Agents

Discord ops · builds · support

High-volume Discord replies don’t need frontier. Pin a small model for chat; let Auto spend premium only on the ugly tickets.

What Changes in Your Code

Usually the base URL and key. That’s the whole diff for most agents.

Beforealways-Claude, always full price
from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ["ANTHROPIC_API_KEY"],
)

resp = client.messages.create(
    model="claude-3-5-sonnet-latest",
    max_tokens=1024,
    messages=[{"role": "user", "content": prompt}],
)

Easy steps still pay Sonnet rates.

Afterbase_url → Yielding Bear; pin or Auto
from openai import OpenAI

client = OpenAI(
    base_url="https://yieldingbear.com/api/v1",
    api_key=os.environ["YIELDINGBEAR_API_KEY"],
)

resp = client.chat.completions.create(
    model="nvidia/nemotron-3.5-lightning",  # free model (use Auto with Max)
    max_tokens=1024,
    messages=[{"role": "user", "content": prompt}],
)

Same OpenAI SDK. Cheaper default model; upgrade the hard calls.

Agent Routing FAQ

An OpenAI-compatible gateway. One key for Hermes, OpenClaw, or a custom runtime. Grizzly routes routine steps to lean models and spends premium only when the step needs it.
