Channel and publications
Latent Space began as a newsletter started by swyx in 2022; its podcast followed in 2023, led by swyx with co-hosts including Alessio Fanelli, and records mostly in person. The podcast and newsletter grew out of an informal Discord community that also runs a weekly LLM Paper Club.2
In a 2024 post marking the podcast's first year, Fanelli describes the show's three episode formats: topic-driven "101" episodes without guests, guest interviews timed to news and releases, and recap or emergency episodes with several speakers, including live coverage of events such as OpenAI DevDay and NeurIPS.4
Open-source work
Fanelli open-sourced smol-podcaster in 2023, a tool that automates parts of Latent Space's production: transcribing episodes with speaker labels and timestamps, formatting the transcript for publication, and using language models to draft chapters and title ideas. The repository describes it as a podcast production agent and is released under the MIT license.56
Earlier in 2023, Fanelli built and open-sourced a web interface for LangChainHub, a collection of prompts for LangChain projects, with a TypeScript and Next.js frontend and a small Ruby backend that indexes the hub's repository.7
