Semantic Data Processing. Build data processing and data analysis pipelines that leverage the power of LLMs 🧠
Semlib is a Python library for building data processing and data analysis pipelines that leverage the power of large language models (LLMs). Semlib provides, as building blocks, familiar functional programming primitives like map, reduce, sort, and filter, but with a twist: Semlib's implementation of these operations are programmed with natural language descriptions rather than code. Under the hood, Semlib handles complexities such as prompting, parsing, concurrency control, caching, and cost tracking.
Hosty is a tiny PHP application to host images (and text, if you want to) on your own webserver. It's meant to be as small as possible and hence offers only the following:
Users configured in the config file can upload images. Optionally, they can also paste code (à la pastebin) with simple syntax highlighting.
Each image/paste gets a randomized URL. Everyone who has the URL can access the content.
Content can be deleted by logged-in users.
That's it. There is no admin UI, no commenting, no tagging, no folders, no social media crap or other external resources.
