Is t5x an encoder/decoder architecture?

Some more general options.

The Flax ecosystem

https://github.com/google/flax?tab=readme-ov-file

or dm-haiku

https://github.com/google-deepmind/dm-haiku

were some of the best developed communities in the Jax AI field

Perhaps the “trax” repo? https://github.com/google/trax

Some HF examples https://github.com/huggingface/transformers/tree/main/exampl...

Sadly it seems much of the work is proprietary these days, but one example could be Grok-1, if you customize the details. https://github.com/xai-org/grok-1/blob/main/run.py

and the implementation https://github.com/google/trax/blob/master/trax/models/resea... if you are interested.

Hope you get to look into this!

Thank you for developing the pipeline and amassing considerable compute for gathering and preprocessing this dataset!

I'm not sure if this is the right place to ask about this, but could you consider training an LLM using a more advanced, sparse transformer architecture (specifically, "Terraformer" from this paper https://arxiv.org/abs/2111.12763 and this codebase https://github.com/google/trax/blob/master/trax/models/resea... by Google Brain and OpenAI)? I understand the pressure to focus on training a straightforward LLaMA replication, but of course you see that it's a legacy dense architecture which limits its inference performance. This new architecture is not just an academic curiosity but is already validated at scale by Google, providing 10x+ inference performance boost on the same hardware.

Frankly, the community's compute budget - for training and for inference - isn't infinite, and neither is the public's interest in models that do not have advantage (at least in convenience) over closed-source ones; and so we should utilize both those resources as efficiently as possible. It could be a big step forward if you trained at least LLaMA-Terraformer-7B and 13B foundation models on the whole dataset.

But a couple years later they came out with open source implementations yeah: https://github.com/google/trax/tree/master/trax/models/reformer

Code: https://github.com/google/trax/blob/master/trax/examples/Terraformer_from_scratch.ipynb

Training language models is expensive. Train the biggest model you can afford. I assume you've tried the colab from the reformer GitHub: https://github.com/google/trax/tree/master/trax/models/reformer

deduplication. We first split the files into words/tokens based on non-alphanumeric characters and remove files with fewer than 10 tokens. Next, we compute the MinHash with 256 permutations of all documents, and use Locality Sensitive Hashing to find clusters of duplicates. We further reduce these clusters by ensuring that each file in the original cluster is similar to at least one other file in the reduced cluster. We consider two files similar when their Jaccard similarity exceeds 0.85.

Near-duplicates are still difficult to measure. So we should expect duplication, and it should be proportional to the number of samples we have (even if the same variance, but I'd wager higher variance with larger duplications).
