Little demo that searches Hacker News comments for a topic (using
https://hn.algolia.com/api), extracts sentiment and other metadata, then generates a research summary.
Really proud of the API we've built at
https://substrate.run – you don't have to think about graphs, but you implicitly create a DAG by relating tasks to each other. Because you submit the entire workflow to our inference service, you get automatic parallelization of dozens of LLM calls for free, zero roundtrips, and much faster execution of multi-step workflows (often running on the same machine).
