Model family: GPT
GPT-5.3-Codex is a new GPT-5.x family model built for end-to-end software and computer work. It advances coding and debugging, web and app building, and professional tasks like docs, slides and analysis, while setting state-of-the-art results on SWE-Bench Pro, Terminal-Bench, OSWorld and GDPval. About 25% faster than GPT-5.2-Codex, it can be steered interactively during long runs and was itself used as an agent to debug, monitor and deploy its own training pipeline.

X X🙏 37 karmaJul 6, 2024@Imagetocaption.aiIt's really frustrating when you try to select something you want, only to be immediately redirected to a subscription-based payment model. There's no opportunity to even test things out, which kills the enthusiasm right away. It seems like everything is geared towards subscriptions nowadays, and it's a turn-off. Companies should prioritize transparency and give customers a chance to try out products before committing to a subscription. Practices like these erode consumer trust and deter many potential customers.
