New model additions

Moshi

The Moshi model was proposed in Moshi: a speech-text foundation model for real-time dialogue by Alexandre Défossez, Laurent Mazaré, Manu Orsini, Amélie Royer, Patrick Pérez, Hervé Jégou, Edouard Grave and Neil Zeghidour.

Moshi is a speech-text foundation model that casts spoken dialogue as speech-to-speech generation. Starting from a text language model backbone, Moshi generates speech as tokens from the residual quantizer of a neural audio codec, while modeling separately its own speech and that of the user into parallel streams. This allows for the removal of explicit speaker turns, and the modeling of arbitrary conversational dynamics. Moshi also predicts time-aligned text tokens as a prefix to audio tokens. This “Inner Monologue” method significantly improves the linguistic quality of generated speech and provides streaming speech recognition and text-to-speech. As a result, Moshi is the first real-time full-duplex spoken large language model, with a theoretical latency of 160ms, 200ms in practice.

Zamba

Zamba-7B-v1 is a hybrid between state-space models (Specifically Mamba) and transformer, and was trained using next-token prediction. Zamba uses a shared transformer layer after every 6 mamba blocks. It uses the Mistral v0.1 tokenizer. We came to this architecture after a series of ablations at small scales. Zamba-7B-v1 was pre-trained on 1T tokens of text and code data.

GLM

The GLM Model was proposed in ChatGLM: A Family of Large Language Models from GLM-130B to GLM-4 All Tools by GLM Team, THUDM & ZhipuAI.

The abstract from the paper starts with the following:

We introduce ChatGLM, an evolving family of large language models that we have been developing over time. This report primarily focuses on the GLM-4 language series, which includes GLM-4, GLM-4-Air, and GLM-4-9B.

Idefics 3

The Idefics3 model was proposed in Building and better understanding vision-language models: insights and future directions by Hugo Laurençon, Andrés Marafioti, Victor Sanh, and Léo Tronchon.

Idefics3 is an adaptation of the Idefics2 model with three main differences:

PhiMoE

The PhiMoE model was proposed in Phi-3 Technical Report: A Highly Capable Language Model Locally on Your Phone by Microsoft.

This model is very similar to Mixtral with the main difference of Phi3LongRoPEScaledRotaryEmbedding, where they are used to extend the context of the rotary embeddings. The query, key and values are fused, and the MLP’s up and gate projection layers are also fused.

Quantization

BitNet

BitNet is an architecture introduced by Microsoft Research that uses extreme quantization, representing each parameter with only three values: -1, 0, and 1. This results in a model that uses just 1.58 bits per parameter, significantly reducing computational and memory requirements. It replaces traditional Linear layers in Multi-Head Attention and Feed-Forward Networks with specialized layers called BitLinears that use ternary precision (or even binary, in the initial version) image

GGUF loading in transformers

More architectures are now supported in our GGUF loader; GGUF files saved with this architecture can now be loaded directly in transformers to be fine-tuned. We recommend using tooling from llama.cpp to requantize the models after further training has been done.

Notable improvements and additions

Pipeline API synchronisation

We are pushing for a unified inference API across multiple libraries. As part of this, we are cleaning up the input and output signatures for our pipeline classes and deprecating some rarely-used arguments. This is still a work-in-progress, but when it's finished, transformers pipelines should exactly match workflows in deployment libraries like transformers.js or TGI, allowing you to seamlessly move from development to production.

Also, pipelines now fully support the Processor class, used by vision-language models. Expect full pipeline support for chatting with VLMs in the very near future!

Executorch compatibility

ExecuTorch is an end-to-end solution for enabling on-device inference capabilities across mobile and edge devices including wearables, embedded devices and microcontrollers. It is part of the PyTorch ecosystem and supports the deployment of PyTorch models with a focus on portability, productivity, and performance.

We are collaborating with the executorch team so that 🤗 Transformers models can be exported using torch.export. The goal of this integration is not only to enable export but also to ensure that the exported artifact can be further lowered and optimized to run efficiently in ExecuTorch, particularly for mobile and edge use cases.
