I'm trying to find if OpenAI can break down how much money i paid in API tokens by just yelling/arguing with the model in all caps.

Well it was only small 1B-3B models so it didn't take up too much time in the workshop πŸ˜…, though I did show an example of a Llama 70B on our A100 GPU.
Also talk about speeding up batch processing since running millions of inferences is tough even with the small models on the GPUs.

Huge thanks to everyone who joined my workshop on #LLMs on #HPC! πŸ™Œ
It started as an Ollama demo on Hoffman2 turned into a great convo on running LLMs on HPC πŸ§ βš™οΈ

I’m all about building tools to make HPC more accessible for everyone πŸ’‘

Curious how others are using HPC for LLMs 🧐

SSH’d into my laptop remotely to move my IP to a new interface.
Ran ip addr del … on the only active one.
Realized what I’d done at the exact moment I hit Enter.
Connection: gone. RIP me. πŸ’€

Running Large Language Models on Hoffman2 - Institute for Digital Research and Education

πŸš€ Doing a new workshop β€œRunning LLMs on Hoffman2” on April 30! πŸ€–πŸ’»
idre.ucla.edu/calendar-eve...
First time doing a #GenAI workshop on #HPC. Showing off a #Ollama Open Webui setup, maybe with LangChain/Rag demo.
I would love to hear ways for researchers to make running GenAI workflows easier on HPC.

As someone currently living in LA, I hope soon more official city, emergency, police, fire, etc. accounts would be more active on this platform.
Trying to get important information on the 'other' platform, I have to scroll past TONS of posts blaming others for the fire and misinformation
