Introduction
There's a new open-source project that aims to build a fully interactive and private conversational AI. It's called Blind Chat, and it is truly impressive. In this blog, we will explore what Blind Chat is, how it functions, its significance for privacy, and ways in which you can incorporate it into your applications. So let's dive in!
What is Blind Chat?
Blind Chat is a privacy-first, in-browser AI chat system that allows you to have natural conversations with large language models without sending any of your data to the cloud. Unlike other chat systems, where your conversations are sent to the company's servers, Blind Chat keeps everything on your device. This means that whatever you say or type stays on your device and cannot be accessed by anyone else, including Blind Chat's creators. It provides you with full privacy while still allowing you to have smooth and seamless conversations with the AI.
Privacy-First Approach
Blind Chat ensures privacy through two main techniques: local inference and secure enclaves.
Local Inference
Blind Chat utilizes standard web technologies, such as JavaScript and Web Assembly, to perform complex computations directly on your browser. It downloads a pre-trained language model (LLM) from a public repository and runs it on your device. This eliminates the need to send any data to a remote server for processing. Even if you want to use a large model like GPT-3 or Flan T5, local inference ensures that your data remains on your device, guaranteeing privacy.
Secure Enclaves
In cases where a large model is too large for your device, Blind Chat employs secure enclaves to run the code in a protected environment. These enclaves are isolated from the rest of the system, ensuring that even if someone accesses the server, they cannot interfere with the program or data within the enclave. Blind Chat uses enclaves to operate big models on trusted servers, encrypting your data before leaving your device and decoding it only within the enclave. This way, you can use any model without the fear of data exposure or threats.
How Does Blind Chat Work?
Blind Chat consists of three main components: the user interface (UI), the private LLM, and the storage.
User Interface (UI)
The UI is what you see when you open Blind Chat on your browser. It provides a user-friendly interface for typing and communicating with the AI model. The UI also ensures the security of your data by encrypting it before sending or receiving it from the private LLM.
Private LLM
The private LLM is the core of Blind Chat. It runs either on your device or on a trusted server within a secure enclave. It receives encrypted data from the UI, processes it according to the task instructions, and sends back encrypted results. The private LLM can be any model that supports text-to-text format, such as T5, Flan T5, or GPT-3.
Storage
The storage component stores the LLM models and their metadata. It can be either a public repository or a private server, depending on the source and ownership of the models. The storage provides access to the models for downloading or running them on demand.
Benefits and Use Cases
For Regular Users
Blind Chat is a great option for regular users who want to engage with conversational AI while prioritizing their privacy. It allows users to choose between local inference, which provides superior privacy but might be less powerful, or remote enclave mode, which utilizes bigger AI models but requires trust in the server. In any case, Blind Chat offers more privacy compared to other chat AI systems.
For Developers
Developers who want to create their own chat AI systems using LLMs will find Blind Chat extremely useful. It supports any LLM model, including those from TF Hub or custom creations. Additionally, Blind Chat offers an easy-to-use API, enabling developers to link their software to Blind Chat, send and receive data from LLMs, and customize the models' behavior.
Blind Chat's Future
Blind Chat has some exciting features on the horizon that will make it even more powerful and useful. One of these features is the addition of connectors, which will allow users to pull data from various sources, such as databases, APIs, and files. This will enable richer and more personalized conversations with LLM models. Additionally, Blind Chat is working on models that can handle multimodal inputs and outputs, including images, audio, and video, further expanding the possibilities for engaging conversations.
Comparison with Other Chat AI Programs
Blind Chat offers a unique and innovative solution for conversational AI that balances privacy and performance. It distinguishes itself from other chat AI programs based on the approach it takes:
On-Device Prediction
Blind Chat's local inference mode works entirely on your device, ensuring privacy and offline functionality. However, it may be less powerful or fast compared to other methods, as it relies on the device's resources and requires model downloading.
Regular AI APIs
Most chat AI programs utilize regular AI APIs provided by big companies like Google or Amazon. While this offers access to strong AI models, it comes with the drawback of sending your data to external servers, which may compromise privacy and security.
Zero Trust AI APIs
Blind Chat's remote enclave mode falls under the category of zero trust AI APIs. It runs on secure servers using technologies like Intel SGX or AMD CV. This allows users to leverage powerful AI models while maintaining data privacy and security. However, it still requires an internet connection and trust in the server provider.
As you can see, Blind Chat provides a compelling solution for privacy-conscious individuals and developers seeking to create their own chat AI systems.
Conclusion
Blind Chat is an open-source project that offers a privacy-first approach to conversational AI. It allows you to have natural conversations with AI models without compromising your data privacy. With its unique combination of local inference and secure enclaves, Blind Chat ensures that your data remains on your device and inaccessible to anyone else. Whether you are a regular user looking for private conversations with AI or a developer interested in creating your own chat AI systems, Blind Chat provides the necessary tools and flexibility. It is a promising project that continues to evolve and improve, with exciting features and expansions planned for the future. If you value privacy and innovative AI solutions, Blind Chat is definitely worth checking out!
