Smart AI routing,
built for teams and agents first.

Introducing Relay by AnchorShell

Characterize the prompt, apply limits and guardrails, and send it through the right model path. Then inspect the decision, timing, tokens, and cost in one trace.

Get started
Self-host on GitHub
Hermes Agent, OpenClaw, Manus, Pi, Blink Claw, and Nanobot send requests through AnchorShell Relay to configured OpenAI, Anthropic-compatible, Z.AI, Cerebras, Grok, and Kimi model paths.

Bring the model accounts you already use.

OpenAI-compatible paths, from cloud to local. Compatible with 100,000+ models.

Running a local LLM? Host it locally and track how much you’ve saved.

Routing decisions, at system-one speed.

Classify the request before the expensive model call. Relay can identify the work, apply routing policy, and choose the model path in milliseconds.

Use AnchorShell’s built-in routing engine or plug in a different System One classifier as your workload evolves.

Benchmark based on a 40M-token illustrative workload. Actual costs depend on your workload, model assignments, and provider pricing.

Stop sending every task to your most expensive model.

Smart Groups characterize the work, identify its primary intent, and follow the model assignments your team approved for that request.

Make the efficient path the default for routine work. Send complex work directly to the capable route instead of paying the same rate for everything.

Prompt exampleSimple request

Turn the attached 28-page incident review into a six-bullet briefing for support leads. Preserve customer impact, dates, and owners, call out the unresolved risks, and leave out the minute-by-minute timeline.

Incident brief was characterized as summarize with 94% confidence and routed first to gpt-5.4-mini.

Example Smart Group assignments. Highlighted phrases illustrate request signals, not hard-coded trigger words. Your team can customize which intent routes to which model. Relay applies it after characterization.

Give every person and agent an identity, a limit, and a paper trail.

Grant approved people and API keys access to shared provider capacity. Attribute every request, then constrain each workload independently.

Prevent runaway agents from chewing through your budget.

Put guardrails exactly where they belong.

Supports guardrail calls to secure your AI infrastructure before or after the LLM call—or both.

You decide what gets checked, blocked, or allowed through.

Prompt injection. Mistral Moderation pre-dispatch: Blocked. Model provider: Not called. Mistral Moderation post-response: Skipped. Request blocked before dispatch.

Non-streaming example. The configured external or local service supplies the verdict; Relay applies the operator-selected action and records the result and timing.

Use the moderation stack you already trust.

Start with an editable AnchorShell preset, or map a remote or self-hosted safety service into pre-dispatch and post-response hooks.

Fallback on Max wait 10s Cooldown ready

Requests move from Queue to Group Models, Active Request Bay, and Completed. When the preferred model reaches its request limit, Relay can use an eligible fallback. A following request waits in queue after the remaining cooldown falls within the 10-second maximum wait.
