Model Training as Code

Aleph Alpha, a company focused on developing large AI models, has launched Savanna, a model factory that implements the entire training pipeline in code. This approach, dubbed Model Training as Code (MTaC), aims to address the complexity and manual coordination challenges associated with training large AI models. By expressing manual steps as functions with typed inputs and outputs, Savanna enables composability, consensus, and provenance, making it easier for teams to collaborate and iterate on model training.

The development of Savanna reflects the growing complexity of model training, which has become an engineering challenge due to the increasing intricacy of individual stages and the need for coordination among specialized teams. As models grow larger and more data-intensive, the cost of failure rises, making manual processes prone to human error and inefficiencies. Aleph Alpha's solution seeks to mitigate these issues by providing a shared, durable artifact for the pipeline, allowing teams to collaborate more effectively.

The implications of Savanna's MTaC approach are significant, as it could enable more efficient and scalable model training for large AI models. By automating repetitive tasks and providing a clear record of provenance, Savanna can help teams avoid duplicated efforts and ensure that learnings from previous experiments are retained. As the AI landscape continues to evolve, the ability to train large models efficiently and effectively will be crucial for companies like Aleph Alpha to remain competitive.
