GPT-5 just refactored my entire codebase in one call. 25 tool invocations. 3,000+ new lines. 12 brand new files. It modularized everything. Broke up monoliths. Cleaned up spaghetti. None of it worked. But boy was it beautiful.

A bit sad how the GPT-5 launch is going so far, especially after the long wait and high expectations - The automatic switching between models (the router) seems partly broken/unreliable - It's unclear exactly which model you're actually interacting with (standard or mini, reasoning level, old/new) - Router issues probably contribute to many negative first impressions ("GPT-5 is bad"), especially when you can't easily tell which model is handling your requests - e.g. GPT-5 Thinking performs better at writing compared to standard GPT-5 ("think harder" prompts might also help) - I'm seeing lots of complaints about legacy models being removed and usage limits for Plus (and also Free) accounts ("bring back 4o, o3, ...") - Context window lengths aren't clear, nor how many and which exact GPT-5 models ChatGPT uses (standard, mini, new, old) - no indicator of which model is active at any moment - The gradual rollout and current capacity constraints add to confusion, because not everyone can access the new models yet - Mixed-up charts during the livestream provided plenty of free material for chart-crime and vibe-charting posts, which hasn't helped build trust or confidence - And of course, the community had extremely high expectations across all fronts and modalities, as usual I'm hoping improvements in the next hours/days, and today's AMA, can clarify some of these open issues and questions

GPT-5 basically one-shot this

Early GPT-5 review: • Best in class as a chat bot • UNREAL for the price • Pure coding perspective Claude Code is still king at the moment I asked both to build me a personal operating system in the style of the Matrix. GPT5 on left, Claude on the right Winner is clear

A compilation of experiences I made with GPT-5 in one shot. The poem camera app is particularly impressive because the model came up with all the details, like the way the photos stack in the gallery, the photo developing animation, etc

Vor weniger als 29 Stunden hat OpenAI GPT-5 veröffentlicht. Und einige Leute nennen es das beste Modell. Einige nicht so sehr. 10 verrückte Beispiele:

Grok 4 vs GPT-5 It's not even close. Grok 4 Auto mode works extremely well, it answered this simple math question in ~1 sec without needing to switch models.
