During a discussion about Anthropic's Claude update cadence, a developer pointed out that the competition isn't waiting. He noted that OpenAI's Codex (with GPT-4o) has become so good that it is now his primary working environment.
While he believes Anthropic still has time to catch up, the current performance of Claude Opus is viewed by some users as a fumble, indicating a shrinking margin for error in the leading AI models market.
