Every cloned its Slack with 51 AI coworkers trained on chat history via DSPy GEPA

Every's @hammermt built a simulated Slack with 51 AI coworkers, with prompts trained from historical Slack messages using DSPy GEPA — Every's editor calls it "we've all been cloned."

The screenshot shows the optimized 3,000+ char system prompt for a digital "Dan" (Dan Shipper): default replies are 1–6 word reactions, idea approvals get brief praise, tasks are delegated by @-tagging teammates, and longer replies only when genuinely explaining a decision. The author notes reading the prompts feels "like reading someone's mind."

The project doubles as a testing ground: simulated coworkers can reply to each other, and even to the real person they're simulating — a novel setup for simulating organizational behavior.
