How a researcher uses Codex and ChatGPT to search for new antimicrobial molecules
A researcher is using Codex and ChatGPT to accelerate the hunt for antimicrobial molecules — showing how AI is reshaping drug discovery workflows.

Why it matters
This is a deployment case study showing AI tools (ChatGPT, Codex) applied to a specific scientific workflow — drug discovery. The story matters to practitioners because it demonstrates a real use of frontier models in a high-stakes domain, and to enthusiasts as evidence of AI's expanding footprint beyond software engineering into biotech.
