Today we're excited to open source Flash: a post-training stack for open weight models
Flash is designed to be cost-efficient and extendable. It handles training algorithms, compute provisioning, and model serving.
Use Flash via the CLI or self host with your own hardware.
- Not every AI interaction is best served with a large frontier model. There is a long tail of trillion-token use cases, from tagging to search, best served by a sub-10b-parameter model that runs in milliseconds and costs many orders of magnitude less than the frontier. We built
