Inspiration

For many of us, the issues of centralization and data mining have exposed the drawbacks of Web 2. Even now, and in conversations I've had with others, it's clear that our emails and phone numbers are no longer as private as they used to be. Just recently, I received an unsolicited message from an unknown number inviting me to join a dubious site. It was evident that my phone number had somehow made its way to people I'd rather not have it. This not only eroded my trust in a company I had once relied on, but it also highlighted the pitfalls of centralized Web 2 platforms.

Frustrated by such experiences and many others, I decided to explore the world of decentralization, where we have more control over our data. However, since transitioning to the Internet Computer blockchain, I've encountered various projects that aim to replace their centralized counterparts. Unfortunately, they all share a common issue – there's a significant gap between users like me and the project founders. It's challenging to convey concerns or get assistance when needed.

Thankfully, I managed to find some of the founders on Twitter, and after discussing the matter, they all echoed a similar sentiment. To be truly decentralized and gain the trust of customers, every aspect of a product must embrace decentralization, and third-party integrations must prioritize user privacy. However, they faced a dilemma – they couldn't find a suitable, pre-built solution that met these requirement to integrate into their dApps to bridge this communication gap. Most contemplated building it themselves, but that would entail assembling a new team and allocating an unprecedented budget.

This is where Nexai comes into the picture, an AI-driven assistant that dApps can seamlessly integrate into their platforms. It's designed with a strong emphasis on security and anonymity, ensuring that users don't have to divulge sensitive information during interactions with the assistant. Furthermore, all conversations are automatically deleted once they conclude.

How we Built Nexai

Nexai's foundation lies in a meticulously crafted vector database, meticulously designed and implemented in Rust. This database harnesses the power of fast approximate nearest neighbor search via the HNSW index, delivering instant-distance calculations. What sets it apart is its innate intelligence and adaptability, achieved through the processing of embedded vector coordinates, each spanning a length of 384. These coordinates serve as the essence of Nexai's learning capability.

The key to Nexai's intelligence is the proximity-based approach it employs. In essence, it creates a virtual landscape where questions and answers are encoded as vector matrices. This landscape allows Nexai to discern the similarity between user queries and existing knowledge, thereby providing contextually relevant and intelligent responses.

This approach shares a resemblance with industry giants like Google, renowned for leveraging vector databases for image classification, text search, and other data-intensive tasks. Nexai's vector database serves as the bedrock of its capabilities.

Now, let's dive into the components that make Nexai function seamlessly:

The Nexai Canister

At the core of Nexai's operation lies the Nexai Canister, a secure middleman between users and the system(vecto. It not only enhances security but also orchestrates the flow of data between the various components. It plays a dual role by serving as a database where companies can store their information and query it effectively.

Vector Database Canister

The vector database stores questions as vectors and groups similar questions closely together in a multi-dimensional space. It searches for similar questions to provide context-aware responses. Questions are stored as vectors in the database, each with a length of 384. Similar questions are placed near each other in the vector space.

The External Canister

Nexai also features an externally accessible canister, aptly named External. This canister is open to the public, enabling universal access. Users engage with this canister to interact with Nexai, directing their queries and receiving timely responses. To streamline this interaction, we've developed the "nexai-assistant" npm package, a client-side tool simplifying user engagement.

From the Company's Perspective:

For companies, the Nexai journey unfolds as follows:

1. Begin by registering your company, which initiates instances on both the vector and Nexai databases.
2. Train your Nexai assistant by providing it with question-answer pairs, enabling it to comprehend and respond intelligently.
3. Store these valuable training sets within the Motoko canister (Nexai) and as embeddings within the vector database.
4. Prior to integrating Nexai into your dApp, ensure your bot's functionality meets your specific requirements.

From the User's Perspective:

For users, Nexai promises a seamless experience:

1. Formulate your query or question.
2. Encode your inquiry using an on-chain model, designed to accommodate substantial data loads with a size of 100MB.
3. Submit your inquiry to the Nexai canister, crafted using the Motoko programming language. The canister handles validation and redirects as needed.
4. The question is then seamlessly transmitted to the vector database for processing.
5. The vector database promptly retrieves an answer, based on the proximity of vector coordinates in the personalized training space tailored to your company's unique knowledge.
6. The retrieved answer undergoes further refinement through an LLM (Large Language Model), benefiting from the computational prowess of WebGPU. The result is a well-informed response that swiftly reaches your screen.

In essence, Nexai is not just an assistant; it's an innovative solution, underpinned by cutting-edge technology, designed to empower both businesses and users alike.

Challenges we ran into

Our path to creating Nexai wasn't without its share of hurdles. Let's delve into the challenges we encountered and how we navigated through them:

1. Tackling the Intricacies of the "Instance-Distance" Library

One of our initial roadblocks was mastering the nuances of the "instance-distance" library in Rust. We needed this library to perform seamlessly within the Internet Computer (IC) blockchain to align with our vision. The intricacies and fine-tuning required for this integration posed a formidable challenge.

2. On-Chain Model Training: Conquering Storage Constraints

Training complex models on-chain, like the resource-intensive Llama model, presented a unique challenge. Although we devised innovative methods to compress these models to approximately 4GB, we bumped into the limitations of the canister's storage capacity. This constraint compelled us to explore creative solutions to ensure optimal model training and performance.

3. Navigating the WebGPU Compatibility Maze

While WebGPU holds immense promise for unleashing the full potential of Nexai, we encountered a compatibility snag. WebGPU's functionality isn't universally supported across all web browsers, which posed a conundrum. To ensure a seamless user experience, we needed to address this compatibility concern and explore alternatives to accommodate a wider user base.
