Validate activity before betting a new project on langstream. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between prism and langstream? prism: Unified interface for working with LLMs in Laravel. langstream: Build robust LLM applications with true composability.
