Great comparison of options for Llama-2 inference, concluding by saying, "Overall, we found Together did best overall across cost, throughput and accuracy followed closely by MosaicML." This is only going to get better. Stay tuned. arjunbansal.substack.com/p/which-llama-…

Excited about models that are sub-quadratic in sequence length and model dimension? Our Monarch Mixer paper is now on arXiv -- and super excited to present it as an oral at #NeurIPS2023! Let's dive in to what's new with the paper and the new goodies from this release: Monarch matrices are an expressive and hardware-efficient set of matrices that generalize the FFT -- and can be used to represent all sorts of fun linear transforms, from Hadamard transforms to Toeplitz matrices and more. Monarch mixer (M2) uses Monarch matrices to mix information both along the sequence (replacing attention) and along the model dimension. M2 replaces attention in Transformers with gated convolutions, and replace the linear layers in MLPs with sparse block-diagonal matrices. The result are architectures that scale sub-quadratically in both sequence length and model dimension! Back in July, we released a short blog post (hazyresearch.stanford.edu/blog/2023-07-2…) with @togethercompute about using Monarch matrices to train some more efficient BERT models -- matching BERT-base in quality with 27% fewer parameters, and with long-context inference throughput. With this release, we're excited to announce two new M2-BERT-large models -- the 260M version matches BERT-large in downstream GLUE score with 24% fewer parameters (and also has much faster long-context throughput). Our paper also has a whole set of theoretical goodness that we didn't get to in our blog post. For causal language modeling -- e.g. GPT-style or decoder-only language modeling -- we need to parameterize the Monarch matrices to make sure that the sequence mixing is causal. This ensures that you can train with next token prediction, GPT-style. We use a mix of polynomial theory to interpret Monarch matrices as bivariate polynomial evaluation, and then causality is just a matter of keeping the degrees in check. (If you're familiar with the FFT convolution theorem, this is equivalent to the padding trick to turn the circular convolution into a causal convolution). Using this theory, we can train M2-GPT models -- fully sub-quadratic in the sequence length. In a weird twist, we found that we can get rid of the MLP layers entirely, and still match GPT performance... wild!

@janekm @vipulved @togethercompute When `stream_tokens` is true, the response is a stream of Server-Sent Events where partial result events are JSON objects and the final event is the string "[DONE]". I'll try to post some sample code (in Python) later today. More details: docs.together.ai/docs/streaming…

Today we are excited to introduce and open-source BLOOMChat a multilingual chat LLM. Built on top of the BLOOM model (@BigscienceW), we further train the model on conversational data from @togethercompute @databricks @laion_ai @huggingface. Some interesting observations: (1/6)

The first RedPajama models are here! The 3B and 7B models are now available under Apache 2.0 license, including instruction-tuned and chat versions! This project demonstrates the power of the open-source AI community with many contributors ... 🧵 together.xyz/blog/redpajama…

In addition to RedPajama 7B, we’ve also been training a 2.8B model. After 600B tokens it is exciting to see the model has higher HELM scores than the excellent Pythia-2.8B & GPT-Neo 2.7B. In fact, trained with twice the tokens, RedPajama-2.8B has comparable quality to Pythia-7B!

Training our first RedPajama 7B model is going well! Less than half way through training (after 440 billion tokens) the model achieves better results on HELM benchmarks than the well-regarded Pythia-7B trained on the Pile. Details at together.xyz/blog/redpajama…

Put a pair of iPhone earbuds through the washer today. Seem to still work. #closecall

Mentioned to @benmang this morning that I wanted to take a trip to Hawaii. Google just served me an ad about trips to Kauai. Creepy.

And I, for one, welcome our new industrial robot overlords. http://j.mp/8Za41n

Selection sort sounds like it belongs in a Daft Punk song. http://jwz.livejournal.com/1278701.html

@emeryvillain: I pronounce the 't' in often, but I also say sik-th instead of sixth. So take that with a grain of salt.

Still coughing after a week. Time to hit the tussin. #theplague

I want to create a web archive of an email mailing list, but Hypermail and MHonArc are so... '90s. Anyone know of a better mail archiver?

After discussing the Taylor Swift iPhone app @david_goodwin has concluded I need a Charles Srisuwananukorn app.

3D TVs seem pretty silly. Anyone thinking of getting one?
