In a fascinating dive into OpenAI’s Codex tuned GPT-5 model, GosuCoder discusses both the accolades and setbacks of this sophisticated AI tool that promises to transform coding practices. The potential that Codex offers to revolutionize code refactoring and tool usage stands out, with Codex Low offering a satisfying middle ground between efficiency and functionality despite notable speed issues. GosuCoder commends OpenAI for their open communication but critiques the model’s slowness, which hinders its usability for real-time coding tasks. Comparing performance across versions of Codex and GPT-5, the differences in speed and function were evident, leading to the suggestion of prioritizing Codex Low until improvements in timing are made. Despite the challenges, the software’s ability to function in diverse coding environments and OpenAI’s proactive handling of model limitations earn praise. Ultimately, while Codex shows promise, its current pace makes medium and high levels impractical for full-time use, emphasizing the need for speed optimizations.
