LLMs provides a unified abstraction over various open-source and hosted language models, allowing developers to load and run models through a single interface. It supports model discovery, prompt and pipeline management, batch processing, and fine-grained control over tokens, temperature, and streaming. Users can easily switch between CPU and GPU backends, integrate with local or remote model hosts, and cache responses for performance. The framework includes utilities for prompt templates, response parsing, and benchmarking model performance. By decoupling application logic from model-specific implementations, LLMs accelerates the development of NLP-powered applications such as chatbots, text generation, summarization, translation, and more, without vendor lock-in or proprietary APIs.

Steel is a developer-centric framework designed to accelerate the creation and operation of LLM-powered agents in production environments. It offers provider-agnostic connectors for major model APIs, an in-memory and persistent memory store, built-in tool invocation patterns, automatic caching of responses, and detailed tracing for observability. Developers can define complex agent workflows, integrate custom tools (e.g., search, database queries, and external APIs), and handle streaming outputs. Steel abstracts the complexity of orchestration, allowing teams to focus on business logic and rapidly iterate on AI-driven applications.
