Passthrough access
Accessing an AI service indirectly through another application or platform.
Passthrough access means you use an AI tool, like a chatbot, not by going directly to its website, but through another app or service. Think of it like using a feature in your phone's camera app that's actually powered by a separate, advanced AI.
For example, a company might build a customer service tool that uses Anthropic's Claude AI in the background. You interact with the company's tool, and it sends your questions to Claude and then shows you Claude's answers. You don't directly interact with Claude itself.
Passthrough access describes a model where a third-party application or platform integrates and offers access to an AI model or service without the end-user directly interacting with the model provider's native interface. This is often achieved via APIs. The integrating platform handles user authentication, query formatting, and response presentation, acting as an intermediary.
This architecture allows for specialized user experiences and workflows built on top of foundational models. Tradeoffs include potential latency introduced by the intermediary layer, data privacy considerations managed by the platform, and the possibility of the platform adding its own processing or restrictions.
Passthrough access is relevant as AI models become more powerful and integrated into broader applications. Companies are increasingly embedding AI capabilities into their existing products, allowing users to benefit from advanced AI without needing to use separate AI-specific interfaces. This trend is highlighted by policy updates from providers like Anthropic, which aim to govern how their models are used through these indirect access points.

The concept of passthrough access is inherent in how software services have been integrated via APIs for decades. It became particularly relevant in AI with the rise of powerful models offered through APIs, allowing developers to build applications that 'pass through' requests to these models.
Use a productivity app that integrates AI features. For example, try a note-taking app that offers AI-powered summarization or a writing assistant that suggests text completions. You are using passthrough access when the app uses an AI model from a company like OpenAI or Anthropic behind the scenes.

Questions people ask
- How is passthrough access different from using an AI directly?
- When using passthrough access, you interact with an intermediary application or service that then communicates with the AI model. Direct access means you are using the AI model's official interface or website.
- Is my data safe with passthrough access?
- Data safety depends on the policies of both the AI provider and the intermediary application. It's important to review the privacy policies of both to understand how your data is handled.
