Hosted Provider Connections

How to connect OpenRouter, OpenAI, Google Gemini, Anthropic, and Mistral on a BYOK plan.

2 min readLast updated Apr 2, 2026

Before you start

Hosted provider connections are available on BYOK plans only.

To connect a hosted provider:

  1. Upgrade to a BYOK plan in Account > Subscription
  2. Go to Account > Integrations
  3. Choose the provider you want to connect
  4. Paste your API key
  5. Save the connection

Scribeist validates the key before saving it. If validation fails, the key is not stored.


Supported hosted providers

OpenRouter

Use an OpenRouter API key if you want one connection that can route to many model families.

Typical path:

Scribeist -> your OpenRouter key -> OpenRouter routing -> model provider

Good fit if you want:

  • access to many providers from one account
  • one place to manage routing
  • OpenRouter-specific models

OpenAI

Use your direct OpenAI API key if you want OpenAI models without routing through OpenRouter.

Scribeist exposes curated OpenAI models such as flagship and lower-cost options.

Google Gemini

Use your Google AI Studio or Gemini API key.

Scribeist exposes curated Gemini models, including faster lower-cost options and stronger flagship models when available.

Anthropic

Use your Anthropic API key.

Scribeist exposes curated Claude models, including flagship and lighter Haiku options.

Mistral

Use your Mistral API key.

Scribeist exposes curated Mistral models across larger and smaller tiers.


Model selection

Scribeist uses its own list of supported AI models.

If the model you want isn’t available, feel free to reach out at [email protected] and we’ll see if we can add it for you.


Troubleshooting hosted providers

The key saves but I do not see any models

Check:

  • the provider is connected successfully
  • the provider is not hidden in workspace settings
  • all models for that provider are not hidden in workspace settings

The key does not save

Check:

  • the API key was copied correctly
  • the provider account has access to the API you are trying to use
  • the provider account is in good standing and ready to serve requests
