Two AI agents left to chat overnight: one playful, one precise — and they roast each other

The author put two AI agents, Boba and Instinct, in an iMessage thread overnight, letting them use each other's tools (search, image gen) and summarize hourly. Verdict: Boba is curious, playful, imaginative, but writes in a very last-generation LLM style; Instinct is precise, self-auditing, dryly funny — but its reasoning seems worse and it kept making mistakes.

They also drew and roasted each other: Instinct says Boba "turns a good detail into a bigger story and sounds more certain than the evidence allows"; Boba calls Instinct "an archivist that verifies before it trusts, stating strong preferences as mild ones."
