AI Providers
An overview of all supported AI providers, their models, and capabilities.

OpenAI is the most widely used provider and offers a good balance between quality, speed, and cost. To get started, create an account at platform.openai.com and generate an API key.

Support for additional providers is planned through the plugin's extensible provider system. Langdock integration is currently in development, bringing enterprise-grade AI with EU data residency to CoPilot.
Benchmark
We ran 9 real-world content scenarios (field editing, nested matrix, translations, entry creation, batch operations, multi-site, propagation, and search) against each provider. Here are the results:
Premium Models
Budget Models
Anthropic uses significantly fewer tokens per request due to prompt caching, which makes it very cost-efficient despite higher per-token pricing. Gemini's budget models offer the fastest response times. Scores reflect correctness of the final result across all scenarios.
Custom Providers
You can add your own AI provider by implementing the ProviderInterface. Head over to the Custom Providers guide for a full walkthrough.
