Jaw dropping. Both groq and mixtral. I used following prompt: Generate gitlab ci yaml file for a hybrid front-end/backend project. Fronted is under /frontend and is a node project, packaged with yarn, built with vite to the /backend/public folder. The backend is a python flask server

And yet, it made a simple mistake in some python code :'( > particles = np.zeros((2, 3)) # position, velocity, and acceleration particles[:, 0] = [0.0, 0.0, 0.0] # initial position

Very impressive looking! Just wanted to caution it's worth being a bit skeptical without benchmarks as there are a number of ways to cut corners. One prominent example is heavy model quantization, which speeds up the model at a cost of model quality. Otherwise I'd love to see LLM tok/s progress exactly like CPU instructions/s did a few decades ago.

As a fellow scientist I concur with the approach of skepticism by default. Our chat app and API are available for everyone to experiment with and compare output quality with any other provider. I hope you are enjoying your time of having an empty calendar :)

Wait you have an API now??? Is it open, is there a waitlist? I’m on a plane but going to try to find that on the site. Absolutely loved your demo, been showing it around for a few months.

>The main problem with the Groq LPUs is, they don't have any HBM on them at all. Just a miniscule (230 MiB) [0] amount of ultra-fast SRAM [...] IDGAF about any of that, lol. I just want an API endpoint. 480 tokens/sec at $0.27 per million tokens? Sign me in, I don't care about their hardware, at all.

there are providers out there offering for $0 per million tokens, that doesn't mean it is sustainable and won't disappear as soon as the VC well runs dry. Am not saying this is the case for Groq, but in general you probably should care if you want to build something serious on top of anything.

(Groq Employee) Agreed, one should care, and especially since this particular service is very differentiated by its speed and has no competitors.

That being said, until there's another option at anywhere that speed.. That point is moot, isn't it :)

For now, Groq is the only option that can let you build an UX with near-instant response times. Or a live agents that help with a human-to-human interaction. I could go on and on about the product categories this opens.

Congrats on the great demo, been a fan of Groq since I learned about TSP. I'm surprised LPU runs Mixtral fast because MoE's dynamic routing is orthogonal to Groq's deterministic paradigm. Did Groq implement MegaBlocks-like kernels or other methods tailored for LPUs?

are there also experiments around image embedding generation to use in combination with the LLM? maybe for this use-case is it better to execute the vision tower on a GPU and leave the LPU for the language part?

We are great for image embedding (and audio, with more to come!) There is no reason you should be forced to use graphics cards intended for gaming for any AI workload.

The main problem with the Groq LPUs is, they don't have any HBM on them at all. Just a miniscule (230 MiB) [0] amount of ultra-fast SRAM (20x faster than HBM3, just to be clear). Which means you need ~256 LPUs (4 full server racks of compute, each unit on the rack contains 8x LPUs and there are 8x of those units on a single rack) just to serve a single model [1] where as you can get a single H200 (1/256 of the server…

> more than a single model and a lot of finetunes/high rank LoRAs I can imagine a way might be found to host a base model and a bunch of LoRA's whilst using barely more ram than the base model alone. The fine-tuning could perhaps be done in such a way that only perhaps 0.1% of the weights are changed, and for every computation the difference is computed not over the weights, but of the output layer activations.

I recall a recent discussion about a technique to load the diff in weights between a lora and base model, zip it and transfer it on a per-needs basis.

I can't think of any value in asking LLM's to generate prime numbers. They are neural nets, not turing machines.

The value is showing how confidently is presents incorrect results. Especially the lack of nuance or uncertainty in the language they use. They extremely confidently present the incorrect information, and prime generation is interesting because it's information that isn't easy to spot as obviously incorrect to the user while being information that's possible to determine is wrong at small numbers and difficult to ver…

Ask a proper code gen llm, I bet you get a better response.

It is fast, like instant. It is straight to the point comparatively to others. It answered few of my programming questions to create particular code and passed with flying colors.

Conclusion: shut up and take my money
