Applicable scenarios

  • Multi-model A/B comparison: switch models freely under the same Cherry Studio Provider, no need to switch Providers

  • Avoid registering one by one: one key, one invoice, and you can use 200+ models

  • Niche models: many smaller vendors are only available on OpenRouter (such as Cohere, Reka, etc.)

Relationship with the Anthropic protocol

By default, OpenRouter wraps all upstream models in the OpenAI protocol format. This means:

  • ✅ Works for regular chat, knowledge bases, and quick assistants

  • ⚠️ Cherry Agent Recommended to use directly Anthropic / CherryIN; do not use OpenRouter (Agent requires the native Anthropic protocol)

  • OpenRouter adds a small markup on top of the original provider’s price (usually 5-10%), in exchange for "one account for all"

  • Some models have a "free" version (free with rate limits); when filtering, pay attention to items with the (free) suffix

  • See the detailed pricing table at OpenRouter Models
