Top Small Language Models to Self-Host in 2024

With the growing demand for AI-driven applications, small language models (SLMs) have gained popularity as powerful yet lightweight solutions. Unlike large language models (LLMs), which require extensive computational resources, SLMs offer the ability to perform complex natural language processing (NLP) tasks without straining your hardware or budget. This guide covers some of the best self-hostable small language models, including their use cases, system requirements, and links to getting started.

Why Choose Small Language Models?

Small language models are efficient and versatile. They are perfect for small to medium-sized businesses, developers on a budget, or AI enthusiasts who want to integrate language models into their applications without relying on cloud services. SLMs are often lighter, faster, and, in many cases, easier to deploy than their larger counterparts, making them ideal for on-premises or personal hosting setups. This article on Forbes provides insight on the rise of popularity of small language models.

Key Small Language Models You Can Self-Host

In this guide, we’ll explore several popular small language models you can self-host. Each model has been selected for its efficiency, compatibility with different hosting setups, and versatility across various NLP tasks.

Factors to Consider When Self-Hosting Small Language Models

When deciding to self-host a small language model, consider the following factors:

  1. Hardware Compatibility: Ensure your hardware meets the model’s system requirements. Most small models are CPU-compatible, though some may benefit significantly from GPU acceleration.
  2. Model Size vs. Task Complexity: Smaller models like MiniLM or SMOLLM2 are ideal for simpler tasks, while models like GPT-J or ALBERT are better suited for complex NLP applications.
  3. Latency and Speed: Self-hosted models offer more control over latency, which can be beneficial in real-time applications like chatbots or personalized user interfaces.
  4. Budget and Maintenance: Small models are typically more budget-friendly, but hosting locally requires monitoring and maintenance to ensure they perform reliably.
  5. Scalability: If your application’s demands increase, you may need to scale up resources or consider more advanced configurations to maintain performance.
