Brief

Om Patel (@om_patel5) claims that Codex surged past Claude Code in downloads after OpenAI shipped GPT-5.5: Codex rose from 3.1M/week in early April to 86.1M the week of May 5, 2026, while Claude Code dropped from a 13.1M peak to 7.2M. He blames OpenAI’s simple pricing and Anthropic’s recent pricing/performance changes for the migration.

Why it matters

@om_patel5 reports Codex downloads jumped from 3.1M/week in early April to 86.1M the week of May 5, 2026, while Claude Code fell from a 13.1M/week peak to 7.2M/week, making Codex roughly 12x the downloads of Claude Code.

Key details

  • Om attributes the shift to OpenAI shipping GPT-5.5 and keeping Codex pricing simple, which he says caused the developer community to move to Codex.
  • Om claims Anthropic’s pricing and performance changes over the prior two months pushed its most loyal power users away, despite Anthropic having built what he calls the best coding agent on the market.
