Comparison
determined vs FastChat
Verdict
Pick determined if determined is an open-source machine learning platform that simplifies distributed training and hyperparameter tuning for PyTorch and TensorFlow applications; pick FastChat if fastChat is a comprehensive open platform for managing large language models (LLMs) that includes capabilities for training, serving, evaluating, and comparing chatbot models via web UIs and RESTful APIs. It powers ChatB.

Shared compatibility
- Python · determined: Python runtime · FastChat: Python runtime
Choose determined if…
- determined is primarily Go; FastChat is Python.
- Pricing: The open-source version under Apache License is free to use. Additional enterprise features may incur costs, though specific pricing details are not provided here..
- Requirements: Installation involves using 'pip' for the CLI and subsequent cluster deployment steps via `det deploy`..
- Tags unique to determined: data-science, deep-learning, distributed-training, hyperparameter-optimization.
- You require a streamlined solution for distributed model training, particularly if you are working with PyTorch or TensorFlow frameworks.
When NOT to use determined
- Seeking a platform that supports more machine learning frameworks beyond PyTorch and TensorFlow.
- Your current stack does not include any of the supported infrastructures like Kubernetes or cloud services where Determined can be deployed.
Choose FastChat if…
- FastChat is primarily Python; determined is Go.
- Tags unique to FastChat: chatbots, distributed-serving, evaluation system, large language models.
- Also covers Inference & Serving, LLM Frameworks.
- - You are looking to train and evaluate state-of-the-art models such as Vicuna or MT-Bench.
When NOT to use FastChat
- - You require a proprietary or closed-source framework; FastChat is open-source under Apache-2.0 license and its use might be unsuitable for environments requiring proprietary solutions.
- - Your chatbot evaluation needs do not align with the types of data used in FastChat's datasets (e.g., human votes, MT-Bench evaluations).
- - You prefer a more user-friendly setup without the need to clone a repository and manually install dependencies; FastChat requires installation from source with additional steps for Rust and CMake on
- + Mac.
