BYOK – Bring Your Own Key:
Use your own AI API in Grace.
Connect any AI provider directly to Grace with your own API key. No tech degree needed.
Jump to step-by-step guide →Your own API key – full control, zero overhead.
BYOK (Bring Your Own Key) means you connect Grace directly to an AI provider of your choice using your own API key. You only pay for what you actually use – without consuming your monthly Grace messages.
BYOK is an optional alternative in Grace: on the Free plan you get 30 free messages per day. If you need more, or want specific models, simply activate your own key.
Pay only what you use
No fixed subscription with the provider. Start with just a few euros.
All major models
GPT-4o, Claude, Gemini, Llama, Mistral & more – you choose.
AES-256 encrypted
Your key is stored securely and can be changed at any time.
Which providers work with BYOK?
You can use direct API keys from major providers – or use a single OpenRouter key to access 400+ models cost-effectively in one app.
Direct Providers
OpenAI (GPT-4o, o3), Anthropic (Claude), Google (Gemini), Mistral, xAI (Grok) and more – one key per provider.
OpenRouter – the all-rounder
A single key for 400+ models: GPT-4o, Claude, Llama, DeepSeek, Qwen & more – often cheaper than going direct. Especially recommended if you want flexibility.
Open Source Models
Llama 3.3, DeepSeek-V3, Mistral Large, Qwen 2.5 and many more – usually much cheaper than proprietary models.
Set up your API key – in under 5 minutes.
