MeetModel is a full-stack conversational AI application based on an iOS frontend, Python backend, and locally running large language models, enabling ChatGPT-like interaction experiences without external APIs. Its core design philosophy is privacy-first—by running locally, it ensures data never leaves the device, providing users with secure and low-cost AI conversation services.
Section 02
With the rapid development of AI technology today, more and more users are paying attention to data privacy and local processing capabilities. The MeetModel project emerged as a response—it provides a complete solution that allows users to run a fully functional conversational AI system on their own devices without relying on external cloud services or paying API fees.
Section 03
The app is built using Swift language and UIKit framework, follows the MVVM architecture pattern, and communicates efficiently asynchronously with the backend via URLSession's async/await features.
Built on the FastAPI framework, it handles requests from the iOS app and manages communication with local LLMs, with good scalability.
Uses Ollama to run local large language models, supporting mainstream open-source models like LLaMA and Mistral. Users can choose the appropriate model based on their hardware.
Maintains complete conversation history, constructs coherent prompt sequences, achieves context awareness, and generates natural and coherent responses.
Section 04
The project deployment process is simple:
Section 05
The fully local running architecture brings two major advantages:
Section 06
The project author has planned several improvement directions:
Section 07
MeetModel provides an excellent reference implementation for developers who want to build private AI applications, demonstrating the technical integration capabilities of full-stack development and proving the feasibility of achieving high-quality AI conversation experiences in a local environment. For scenarios focusing on data sovereignty and operational costs, this architecture pattern is worth in-depth research and reference.

Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
This project explores how to use Large Language Models (LLMs) to detect logical vulnerabilities in Ethereum smart contracts, especially business logic flaws that are difficult for traditional static analysis tools to capture, such as economic manipulation and execution order errors.
Cross-generational hardware testing based on NVIDIA A10G and H100 GPUs, comparing and analyzing the throughput, latency, and concurrent scalability of three mainstream LLM inference frameworks. SGLang achieves a 3.4x performance advantage over vLLM on H100, while Ollama faces architectural bottlenecks in high-concurrency scenarios.
