Thank you for reporting this issue, DavidGOrtega. We will investigate and try to reproduce the problem in a controlled environment. In the meantime, if you have any other details or find anything that could help, please let us know. We'll get back to you as soon as we have more information or a resolution to the issue. This is an ongoing experiment by @mudler, and we're here to help improve LocalAI.
This happens when the prompt exceeds the context size and there is no more space for the response - looks like something we could handle on our side and fail cleanly instead.
What's your context size window? Can you share your model config/ setup?
@mudler Im no even using that model as I use mine, and nothing is apparently requesting it. The only thing I did with that model was install it and then delete it after try it. Is that model gpt-4?
An easy way to hang the system is to make several requests to tts endpoint in a row (in my case no more than three) to generate the speech of a larger text. it hangs and never timeouts.
Tested with piper and bark
I confirm this issue. Use LocalAI (v2.14.0) with Orca2. Here are logs:
