Anthropic provides the language model that decides what your agent says. It does not provide voice or transcription, so pair it with a provider for each of those.

​
What you need

​
Getting your API key

  1. Sign in at console.anthropic.com.
  2. Create a new key.
  3. Copy it immediately — the Console shows the key once and only a hint afterwards.
Keys begin with sk-ant-api03-.
Keys belong to a workspace. Rate limits are set per workspace, so a key from a workspace with low limits will throttle even when your organization has headroom to spare. If you expect volume, put the key in a workspace sized for it.
Make sure the account has credit. A key with no billing set up authenticates but fails on the first call.

​
Adding the connection

  1. Go to Connections and choose Anthropic.
  2. Paste the API key.
  3. Save.
SentiVue Talk validates the key with Anthropic as you save, so a bad or expired key is caught immediately rather than on a live call.

​
What you can select afterwards

Select Anthropic as your LLM provider on Model Configurations, then pick a model. Latency is heard as a pause on a call, so start with the fastest model and move up only if the agent struggles with your prompt. Test the difference on a real call before deciding. The dropdown lists the versions available. If the one you want is not there, type its name in — the field accepts any model your account can reach. See Anthropic’s model list.

​
Completing the pipeline

Anthropic covers the language model only. You also need: Each is a separate connection.

​
Troubleshooting

Confirm you copied the whole key including the sk-ant-api03- prefix, that it has not been revoked in the Console, and that the account has credit.
Rate limits apply per workspace, not per organization. Check the limits on the workspace the key belongs to, and move the key to a workspace with higher limits if needed.
Switch to Haiku. Opus is noticeably slower, and in a voice conversation that delay is heard as the agent hesitating.
