Next-Gen AI Models

At Hesper Labs, we build scalable AI models for different needs. Our work includes Small Language Models (SLMs) for efficiency, custom AI agents for specialized tasks, and fine-tuned LLMs for domain-specific accuracy. Each model is designed to be practical, reliable, and adaptable to real-world challenges.

Agent: Mail

Agent: Mail is an open-source command-line agent optimized for Raspberry Pi 5 (8GB). It uses small language models to read and summarize IMAP emails, supporting qwen2.5:3b (default), phi3:3.8b, and llama3.2:3b.

With a lightweight tool-calling workflow, Agent: Mail can list unread emails, extract metadata (subject, sender, UID), and generate concise summaries of individual messages. Configuration is managed through a simple .env file, making setup fast and portable.

Built with Ollama, LangChain, and LangGraph, the project demonstrates efficient LLM integration for constrained environments.
