We have moved past making large language models (LLMs) better and are now focused on using them to create AI applications that help businesses. This is where large language model operations (LLMOps) tools come in, simplifying the process of creating fully automated systems for building and deploying LLM solutions into production.

In this article, we will look at different tools like LLM APIs, fine-tuning frameworks, experiments tracking tools, LLM Integration ecosystem, vector search tools, model serving framework, deployment platforms, and observability tools. Each tool is excellent at what it does and is designed to solve specific problems related to LLMs.

What is LLMOps?

LLMOps is an emerging field that focuses on the operational management of large language models in production environments. It is essentially MLOps (machine learning operations) specialized for language and other multimodal models.

Take the Master Large Language Models (LLMs) Concepts course to learn about LLM applications, training methodologies, ethical considerations, and the latest research.

LLMOps encompasses the entire lifecycle of large language models, including data collection, model training or fine-tuning, testing and validation, integration, deployment, optimization, monitoring and maintenance, and collaboration. By structuring projects and automating processes, LLMOps helps you reduce errors and efficiently scale AI applications, ensuring models are robust and capable of meeting real-world demands.

In short, LLMOps tools help you build an automated system that collects data, fine-tunes the model on it, tracks the model's performance, integrates it with external data, creates the AI app, deploys it to the cloud, and observes the model's metrics and performance in production.

The Developing Large Language Models skill track consists of 4 courses that will help you build a strong foundation on how LLM works and how you can fine-tune pre-trained LLMs.

Now, let’s explore the top LLMOps tools available today.

API

Access language and embedding models using API calls. You don't have to deploy the model or maintain the server; you only have to provide an API key and start using the state-of-the-art models.

1. OpenAI API

OpenAI offers API access to advanced LLM models like GPT-4o and o1. These models can be used via a Python package or CURL command. 

The API is an ideal solution for startups without a technical team to fine-tune or deploy models in production. It provides access to language models, multimodal models, function calling, structured outputs, and fine-tuning options. Additionally, you can use embedding models to create your own vector database. In summary, it offers a comprehensive, low-cost AI ecosystem.

Learn how to use OpenAI Python API to access state-of-the-art LLMs by following the GPT-4o API Tutorial: Getting Started with OpenAI's API
