AI agent swarms are a massive waste of tokens with zero quality gain, says OpenAI Codex developer

OpenAI Codex developer Eric Provencher warns that running more than two parallel AI sub-agents burns tokens without improving output quality.

Eric Provencher, a Codex developer at OpenAI, said on X that parallel agent swarms incur a 'coordination tax' because agents redundantly verify each other's work. He cited a project where 1,393 Fable agents spent $20,000 in tokens refactoring a single Python file, arguing a single Astra agent could have done it for a fraction of the cost. He recommends delegating tasks to threads that notify the main agent on completion rather than constant polling, and acknowledged OpenAI still needs better solutions.

Key facts
  • Provencher says over two parallel sub-agents yield zero quality gain
  • Cited case: 1,393 Fable agents spent $20,000 refactoring one Python file
  • Recommends completion-notification delegation over status polling
  • System prompts execute redundantly across sub-agents lacking context

OpenAI Codex developer Eric Provencher warns that running more than two parallel sub-agents almost always burns tokens without improving quality because agents don't trust each other and end up double-checking everyone's work.
