ChatGPT shamelessly copied Claude.

TL;DR

ChatGPT has launched a new mega-app featuring integrated Codex (coding tool) and a new 'ChatGPT Work' mode for non-coding tasks.
The update includes a new flagship model (5.6) with three intelligence levels (Sol, Terra, Luna) and adjustable 'efforts,' leading to complexity and confusion for users.
Accessing the new ChatGPT requires uninstalling the old app, downloading the new one, and having a paid account ($20/month minimum).
Users frequently encounter 'out of usage' messages with ChatGPT Work and Codex, even on paid plans, suggesting restrictive usage limits.
Upgrading to ChatGPT Business or Enterprise plans reveals significantly higher costs, especially for larger teams, making it potentially much more expensive than Claude.
Claude remains competitive, particularly for businesses up to 150 seats, offering virtually unlimited usage on its $100/month tier.
ChatGPT's strengths include its powerful image generation capabilities and the introduction of 'Sites' for creating web pages, though the latter is still developing.
Despite the new features, the author concludes that Claude is generally preferable due to its simpler structure and more manageable costs, especially for teams comfortable with its interface.
The choice between ChatGPT and Claude ultimately depends on team familiarity and adoption, as the real opportunity cost lies in paying for AI tools that aren't used effectively.
