Proxy
An intermediary that connects systems or users, often used to route requests or mask identity.
A proxy is like a middleman. Imagine you want to talk to someone who speaks a different language. You might use a translator to relay your message. A proxy does something similar for computers or AI systems.
In AI, a proxy can help connect different tools or models. For example, if one AI model can't directly access a website, a proxy can act as a go-between, fetching the information and passing it along. This allows different systems to work together even if they aren't designed to communicate directly.
A proxy server acts as an intermediary for requests from clients seeking resources from other servers. It can be used for various purposes including caching, security, access control, and masking the client's IP address. In the context of AI, proxies can facilitate communication between different models, services, or applications, enabling complex workflows or the integration of specialized tools.
The term proxy is appearing because developers are finding ways to route AI model requests through intermediary systems. This allows them to use alternative, cheaper models or to integrate AI capabilities in novel ways, as seen with Anthropic's tools being used with non-Anthropic models. Microsoft's mention suggests proxies are also relevant for managing how AI agents interact with other systems.

- Anthropic Claude
- Anthropic's tools are being used with other AI models, implying a proxy setup where their code is not directly calling Anthropic's own models.
- Microsoft Copilot
- Microsoft is building AI agents that can be deployed from a terminal, suggesting proxies will be used to manage their interactions with external systems and services.
The concept of a proxy server originated in early networking to manage and control access to resources, with early implementations appearing in the 1990s.
You can try using a web proxy service to access a website that might be blocked in your region. Simply search for 'web proxy' online, choose a service, and enter the URL of the website you want to visit. The proxy will fetch the page for you.

Questions people ask
- What is the main purpose of a proxy?
- A proxy acts as an intermediary, forwarding requests and responses between a user or system and another server. This can be for security, performance, or to bypass restrictions.
- How does a proxy differ from a VPN?
- A VPN encrypts all your internet traffic and masks your IP address for general privacy, while a proxy usually handles traffic for a specific application or service and may not offer the same level of encryption.
