## Definition

**PromptLayer** is a prompt-engineering platform, co-founded by Jared Zoneraich, that supports iterating on the “source code” of an LLM application through its three core primitives: the **prompt**, the **eval**, and the **data set** [^d351f8cb-2125-5ece-8488-6f6ee66c9ee2@120].

In the captured material, **PromptLayer** appears as the company behind the prompt-engineering platform explored in _How to Win With Prompt Engineering_ (Ep. 38). Its co-founder and CEO, **Jared Zoneraich**, presents PromptLayer as a home for the **prompt engineering workflow**: iterating on the “source code” of an LLM application through three core primitives — the **prompt**, the **eval**, and the **data set** [^d351f8cb-2125-5ece-8488-6f6ee66c9ee2@120].The episode argues that prompt engineering endures because its real job is **putting domain knowledge into your LLM system** — the pleasantries may be automated away, but the core primitives remain [^d351f8cb-2125-5ece-8488-6f6ee66c9ee2@151]. PromptLayer, as presented here, is the platform that houses that workflow: encoding domain knowledge into reusable artifacts and correcting the system when it misses, rather than relying on one-off trial and error.\PromptLayer is the prompt-engineering platform founded by Jared Zoneraich, featured in Ep. 38.\\Its workflow is built on three primitives: the **prompt**, the **eval**, and the **data set**.\\The platform treats prompts as the “source code” of an LLM application to be iterated on deliberately.\
