CoAuthor Admins can bring their own LLM and set a default model for their sponsor spaces, routing AI requests through an IT/InfoSec-approved provider such as OpenAI or Anthropic — without any change to the medical writer experience. This requires an initial setup step completed with the Certara DevOps team before the option becomes available in the app.
Setup process
Your organization provides LLM API keys to Certara.
Certara DevOps updates your configuration file to include the desired model.
Your CoAuthor instance is restarted.
Supported LLM providers
OpenAI
Anthropic
Step-By-Step Instructions
Log into CoAuthor
Access the Admin Dashboard.
Open Sponsor → Details for the sponsor you want to edit.
Find the “Default LLM Model” dropdown (under AI Settings).
Click the dropdown and pick the model you want (the list comes from Layar’s
available‑modelsAPI).
A green toast will confirm “Success! Model has been updated"
The default LLM may be reset by clicking Reset to Default (gpt-oss-120b) after a different model is chosen.
