What it does

Llm4s allows startup founders to program AI agents and Large Language Models (LLMs) using the Scala programming language

When to use it
  • •When building a conversational interface that requires complex reasoning and decision-making
  • •When integrating LLMs into an existing Scala application to improve text analysis and generation
  • •When creating custom AI agents that interact with users or other systems in a Scala-based environment
Ready-to-paste prompt
agent.generate("Explain the concept of artificial intelligence in 100 words")
Heads up: Make sure you have Scala 2.13 or later installed, as llm4s is not compatible with earlier versions of the Scala runtime
