Should you Fine-Tune or Train from Scratch?
1) Dataset size is dependent upon the model architecture used for training and the task. If you are unsure, our world-class engineers will be happy to help
2) Domain similarity assess if the data used to pre-train a generic model and your data are similar enough such that your fine-tuned model will perform well on downstream tasks

* T5 tokens to train from the original T5 paper. Chinchilla scaling laws not applicable.
** Note that GPT-J was pre-trained on ~400B tokens. Fine-tuning jobs can employ a wide range of dataset sizes, but often use order 1-10% of the pre-training tokens. As such, one might fine-tune a model like GPT-J with ~4-40B tokens. We provide estimated wall clock time to fine-tune train the model checkpoints above with 10B tokens on Cerebras AI Model Studio and an AWS p4d instance in the table above to give you a sense of how much time jobs of this scale could take.

FAQ
Training large Transformer models such as GPT and T5 on traditional cloud platforms with graphics processors is painful, expensive, and time consuming. The largest instance typically offered in the cloud is an 8-way GPU server. It often takes weeks just to get access. Networking, storage, and compute cost extra. Set up is no joke. Models with tens of billions of parameters take weeks to get going and months to train. If you want to train in less time, you can attempt to reserve additional instances – but unpredictable inter-instance latency makes distributing AI work difficult, and achieving high performance across multiple instances nearly impossible. The result is very few large models are ever trained in a traditional cloud.
Our Solution
The Cerebras AI Model Studio makes training large Transformer models for language or generative AI model applications fast, easy, and affordable. With Cerebras, you have millions of cores, predictable performance, no parallel distribution headaches – all of this enables you to quickly and easily run existing models on your data or to build new models from scratch optimized for your business.

This offering is all about simplified access to large-scale compute to train large-scale language models in short time. We have provisioned specific CS-2 accelerator resources for each model above to deliver the throughput needed to reach the target number of tokens in the listed time. This way, when you use the selected Model Studio code and configuration, you can be sure you’ll complete training to the listed number of tokens. And you can always get more CS-2 resources if needed – contact us to learn more. The Model Studio has access to an elastic pool of CS-2 resources, up to and including large 16-node CS-2 wafer-scale clusters like Andromeda.
The production training run is intended to be a single run from scratch to the listed number of tokens (for most models above, the number of tokens listed is defined by the Chinchilla model scaling laws for large language models). We understand that model development involves a lot more, and your production training run may not go off without a hitch – see below for more information on those issues. When you select a model and purchase one of our fixed price production training run offerings, you’re essentially getting a pre-defined pool of CS-2 resources for the listed amount of time. By using our code and configuration, we ensure sufficient accelerator resources to deliver the token throughput needed to train to the listed number of tokens in the advertised time. Need more time or more accelerator resources? No problem, we have both.
Yes! The Cerebras AI Model Studio is a fully provisioned model development facility. As needed, you can rent CPU hours for data preprocessing and input pipeline development, you can rent additional CS-2 accelerator resources as needed for hyperparameter tuning – pre-production experimental training runs – training eval as needed, and compute resources for production inference after training. We can support fine-tuning, continuous pre-training, and model re-training as well.
Not every run is perfect. If you run into issues, we’ll work together. If the issue is with Cerebras AI Model Studio code or systems, we’ll credit you back the time and help you start again. If the issue is a user or ML matter (e.g. suboptimal hyperparameters for the run), you’ll retain the remainder of your system allocation time and can procure more time as needed to finish the run to your desired end state. We’re here to help you be successful.
Yes! We will provide pre-trained checkpoints for the listed models trained on public, open-source data, and you can purchase CS-2 accelerator resources to train. Contact us to learn more.
Cerebras AI Model Studio provides a ready-to-use training environment, with all required software components already installed and configured. Running training jobs with a multi-million core AI system in the Cerebras AI Model Studio is as easy as running training jobs on a single GPU – no need to manage distributed resources, no need to worry about loading and saving checkpoints across many nodes, no need to think about complex hybrid parallelism strategies, no need to distribute shards of the optimizer state parameters. Cerebras AI Model Studio uses model implementations in the Cerebras Model Zoo in standard PyTorch and TensorFlow. Feel free to take a look!
