# Bring your own model (BYOM)

> Configure a custom Anthropic API key so all inference runs on your account.

# Bring your own model

Business and Enterprise plans can configure a custom Anthropic API key. When active, all inference (scoring, coaching, agents, recommendation generation) runs on your key, and plan credits are bypassed entirely.

## Setup

**1. Open Settings**

Head to **Settings > LLM Provider** in the app nav.

**2. Drop your API key**

Paste your Anthropic API key. The key is encrypted at rest with AES-256-GCM and is never stored in plaintext.

**3. Verify**

Hit **Test connection** to confirm the key works. We send a minimal test request to confirm access.

**4. Activate**

Toggle **Use custom key** to activate. All subsequent inference runs on your key.

## How it works

| Feature | With plan credits | With custom key |
| - | - | - |
| **URL scoring** | 10 credits per score | No credit cost; billed to your Anthropic account |
| **DAC coaching** | 1 credit per message | No credit cost |
| **Agent runs** | 0.1 credits per call | No credit cost |
| **Model used** | Claude (Dacard-managed) | Claude (your key) |

## Requirements

* **Plan:** Business or Enterprise
* **Key type:** Anthropic API key with sufficient quota
* **Models:** your key must have access to Claude Sonnet (used for scoring and coaching)

## Security

* Your API key is encrypted with AES-256-GCM before storage
* The key is never logged, displayed after entry, or included in API responses
* You can rotate or remove your key at any time from Settings

> [!NOTE]
>
> When you're on a custom key, we don't throttle or rate-limit your usage. Your Anthropic account's rate limits and billing apply directly.
