Hidden-orchestrator multi-agent debate on free-tier APIs: opposing personas beat identical ones
Adept_Direction2591 · reddit · 2026-10-21
A developer shares lessons running a multi-agent debate system on free-tier APIs: persona bots debate a question while a backend-only orchestrator decides when to stop and who speaks next. Key findings: same-model agents with identical prompts just echo each other, opposing biases produce real debate; a judge that can't see the original framing is more honest; and free-tier rate limits forcing short rounds accidentally improved quality. The author is building Lunaar (BYOK, free, no key stored) and asks how others pick the next speaker — LLM call or fixed rotation.
