Sharon MachlisMy early impressions of the ChatGPT Web UI with GPT-5 are pretty negative for an <a href="https://masto.machlis.com/tags/RStats" class="mention hashtag" rel="nofollow noopener" target="_blank">#RStats</a> project I’m working on. Code that doesn’t work, not understanding context & follow-up questions. Am guessing I was routed to the less capable mini or nano models at times. I still like Claude Opus 4.1, but I bump up against Web limits quickly. Google Gemini 2.5 Pro is promising with a lot of context and instructions.
