About AutonomousX

AutonomousX focuses on open-source contributions aimed at building Large Language Models from scratch using custom training pipelines. Our work explores different training configurations including optimizers, datasets, and scalable TPU training using JAX and pmap. The goal is to provide transparent and reproducible implementations so that researchers, students, and developers can understand how modern LLMs are trained end-to-end.

Due to the current scarcity of complete beginner-friendly guides for training LLMs on TPUs, especially using JAX, AutonomousX aims to bridge this gap by publishing full training pipelines, scripts, and documentation for the open-source community.

🚀 Run Inference (Colab TPU/GPU)

The trained LLM inference script and model weights are available at: autonomousX/Instinct-1-124m on Hugging Face.

⚠️ Disclaimer: This is a sample inference script originally written for the 0.5B (40B) variants. Please adjust parameters like N_LAYERS, D_MODEL, N_HEADS, D_HEAD, D_FF, etc., according to this specific model's architecture (124m) to run inference successfully.

A ready-to-run Google Colab TPU/GPU inference script is provided below. Simply open a notebook, set your runtime to TPU or GPU, and run it. (Please be patient, it may take around 20 mins to run the model initialization).
