class RubyLLM::Chunk

A Chunk is one streamed fragment of an assistant response. Chunks are yielded to the block passed to Chat#ask or Chat#complete when streaming. A Chunk is a Message, so it responds to the same readers, but it holds only the data received in that part of the stream, such as a piece of content, partial tool calls, or the finish reason on the final chunk.

chat.ask "Write a haiku about Ruby" do |chunk|
  print chunk.content
end
