Claude Haiku and Dome

1. 01

   Connect Anthropic

   tier: small marks it as the model contractors may use. Triage agents call with their own keys; the Anthropic key stays put.

   $ dome models add haiku-45-anthropic \
     --provider anthropic \
     --model claude-haiku-4-5 \
     --api-key "$ANTHROPIC_API_KEY" \
     --attributes '{"tier":"small"}' \
     --gateway prod-gateway

2. 02

   Connect Amazon Bedrock

   Bedrock's Haiku id is us.anthropic.claude-haiku-4-5-20251001-v1:0. AWS keys go in through the dashboard, with tier: small on this connection too.

3. 03

   Pool them for failover

   A failed classification retries on Bedrock instead of joining a backlog.

   $ dome models pool create claude-haiku-4-5 \
     --failover-max all --gateway prod-gateway
    
   $ dome models pool member add claude-haiku-4-5 haiku-45-anthropic --priority 0
   $ dome models pool member add claude-haiku-4-5 haiku-45-bedrock --priority 1

4. 04

   Point your agent at the Gateway

   A triage agent written against the OpenAI SDK only needs the Gateway URL and its Dome key.

   from openai import OpenAI
    
   client = OpenAI(base_url=f"{GATEWAY_URL}/v1", api_key=DOME_AGENT_KEY)
   client.chat.completions.create(
       model="claude-haiku-4-5",
       messages=[{"role": "user", "content": "Classify this ticket: billing, bug or other."}],
   )

5. 05

   Cap tokens per agent

   An agent quota counts every model call that agent makes, through any pool.

   $ dome quotas set --subject agent --agent batch-classifier \
     --dimension llm --unit tokens --limit 5000000 --window daily

Commands and rules tested against a Dome workspace on October 1, 2026. For anything about Claude Haiku itself, see Anthropic's documentation.

forbid (principal, action == Dome::Action::"llm:invoke", resource is Dome::LLMModel)
when {
  principal has act_as &&
  principal.act_as.groups.contains("contractors")
}
unless { resource has tier && resource.tier == "small" };
