Anyone getting overly long responses via API?

I send the prompt: “Tell me the story of the three little pigs in 100 words or less”. I get a response like this:

" The first little pig built his house out of straw. The big bad wolf came and huffed and puffed and blew the house down. The first little pig ran to the second little pig's house, which was made of sticks. The wolf came and huffed and puffed and blew that house down too.

Hi @rached, I haven’t received long responses as such, I tried with the same prompt: “Tell me the story of the three little pigs in 100 words or less” got response of around 100 tokens and for prompt: “Tell me the story of the three little pigs” got response of around 500 tokens.
Thanks & Regards

@rached Thank you for bringing this to our attention! The behavior you observed is rare but possible due to how the model handles ambiguous instructions.

When the model receives a prompt like “Tell me the story of the three little pigs in 100 words or less,” it attempts to satisfy not just the word limit but also anticipates follow-up queries, sometimes resulting in overly detailed outputs. This occurs because the model tries to provide exhaustive context to enhance user satisfaction.

We classify this as a “one-in-a-million” scenario because:

  1. Most responses adhere to constraints like word limits, and exceptions are rare.
  2. This is typically triggered by prompts where brevity and detail are both implied, causing the model to err on the side of verbosity.

We’re continually optimizing the model for such cases, and your feedback is invaluable in helping us improve. Please let us know if you encounter similar issues or have further concerns!
