Hey Hacker News! I'm Alex, one of the founders of Pantograph. A year ago, my cofounder Kelsey and I set out to try to make the most inexpensive robot that's capable enough to do in…

exciting! you could imagine brain transcriptions being very high signal RLHF data that could help align models more deeply to human preference.

Pretty different--obviously a lot less consistent today, but capable of a lot more diverse kinds of behavior. As the models get bigger, they'll be easier to prompt, and you could i…

Awesome! We should be a lot better than ordinary LLMs, especially at tasks that require making a lot of decisions in real-time.

Probably not the current model, but one of the benefits of doing internet-scale pretraining is that the model has seen a lot of mods already! We think the bigger models will be abl…

The goal conditioning is just a training objective! You could combine it with tool use, web searches, etc. and still train end-to-end on goal conditioning. (One way of thinking abo…

you don't need to pick good images manually! it's similar to next-token prediction, many prediction tasks aren't especially interesting, but there are enough hard ones that the mod…

Not yet, but we'll add language as a modality to the larger models! The models are trained end-to-end on video data, so we'll need datasets that mix video and language, e.g. transc…

Very much inspired by those papers! One of the things that's interesting about our model is it's goal-conditioned, so it can do any task at inference time without training on it. W…

Hey everyone! I'm Alex, one of the founders of Pantograph. We've spent the last six months building a pretty smart Minecraft model, coming soon to a server near you! We trained it …

Ah the hardware isn’t gonna be in SF (not the cheapest datacenter space) But I do think a lot of our customers will be out here —- SF is still probably the best place to do startup…

Yeah we aren’t going to let anyone book the whole thing for years. If we ever have to make the choice, we’ll choose the startups over the big companies.

Ah that’s only if you pay for 3 years of compute upfront. Most startups, especially the small ones, really can’t afford that

Yeah it’s pretty hard to find a big block of GPUs that you can use for a short time, esp if you need infiniband for multinode training. Lambda I think needs a min reservation of 6-…

Yeah exactly. That's why you can't really do it with a language model like GPT-3, you have to bake into the architecture the concept of a "link" as a first-class object.

Hey, thanks for posting! We actually have an architecture that lets us expand the index without doing any retraining, so we can add/update pages pretty much for free.

Hey everyone! Metaphor team here. We launched Metaphor earlier this morning! It's a search engine based on the same sorts of generative modeling ideas behind Stable Diffusion, GPT-…
