I'm using a mix of 7B and 13B models that have been fine-tuned using LoRA for specific tasks and they work fantastically depending on the specific task at hand _after fine-tuning_. Generally they're kind of garbage in my experience without fine tuning but I haven't tested the base models directly for tasks besides the statistics at the beginning of the training run.
As for performance, I'm generally seeing 40-50 tokens/sec per model on a Tesla family Nvidia GPU but I keep multiple models loaded and active at a time so that estimate is probably a bit low for overall throughput (I also realized that our monitoring doesn't have any cumulative GPU token rate metrics just now thanks to this question hahah).
Interesting anecdote others may be interested in... I'm rate limiting the output from our streaming API to 8 tokens/sec to artificially smooth out front-end requests. Interactive users will wait and even prefer seeing the stream of the response, and non-interactive users tend to base their performance expectations on the what the streaming API does. It's kind of sneaky but I'm also artificially slowing down those API requests.
