ml5.js
The browser is where JavaScript first appeared, so it’s a natural fit for machine learning applications written in JavaScript and TypeScript. ml5.js is a library for machine learning that’s ready to be incorporated into browser-based machine learning applications. This tool is popular with educators who want to give their students the hands-on experience of building and training models. Some pair it with TeachableMachine for visual experiments. Others just hardwire it into their own personal web page.
Vercel AI SDK
The AI SDK from Vercel is a clearinghouse for accessing models from all the major LLM vendors and many smaller ones, too. Just insert your code into any of the major JavaScript frameworks (Angular, React, Vue, etc.) and let it send out prompts for answers from an LLM. There are more than a dozen different options including big-name options from Azure, Mistral, Grok, and Perplexity. The SDK worries about the differences between the respective APIs, so you don’t have to.
LangChain
As AI developers grow more sophisticated and start building more complex architectures with multiple calls to various models, tools like LangChain are invaluable. The meta tool abstracts away the process of calling different models, while simultaneously stringing together multiple calls to tackle complex tasks and unlock agency. Devops teams also can use LangChain to monitor application behavior in production.
