Anthropic (Claude)

Sinaptic® DROID+ supports Anthropic's Claude models natively, including Claude Opus, Sonnet, and Haiku.

Setup

1. Get an API key from console.anthropic.com
2. Add it to your environment or .env file:

export ANTHROPIC_API_KEY=sk-ant-...

3. Configure in droid.yaml:

anthropic:
  base_url: "https://api.anthropic.com"
  api_key: "${ANTHROPIC_API_KEY}"

Agent Config

To use a Claude model, set the provider to anthropic in your agent config:

name: "claude-agent"
model:
  provider: "anthropic"
  name: "claude-sonnet-4-20250514"
  max_tokens: 4096
  temperature: 0.7

Available Models

Model	Best for	Context
claude-opus-4-20250514	Most capable, complex tasks	200K
claude-sonnet-4-20250514	Balanced performance/cost	200K
claude-haiku-3-5-20241022	Fast, cost-effective	200K

Check Anthropic's docs for the latest models.

How It Works

Sinaptic® DROID+ translates the OpenAI-compatible request format to Anthropic's Messages API internally. Your clients still use the standard OpenAI SDK — Sinaptic® DROID+ handles the conversion:

# Client code is the same regardless of backend model
from openai import OpenAI

client = OpenAI(base_url="http://localhost:8080/v1", api_key="any")

response = client.chat.completions.create(
    model="claude-agent",   # Agent name, not the model name
    messages=[{"role": "user", "content": "Hello!"}]
)

Notes

• Anthropic models support tool use (function calling) natively. All Sinaptic® DROID+ tools (built-in, REST API, MCP) work with Claude models.
• Claude models have different token pricing than OpenAI. Check Anthropic's pricing for details.
• The temperature parameter works the same way, though Anthropic models may behave slightly differently at the same temperature value.
