OpenAI has introduced a new model, with some outlets referring to it as GPT-5.3-Codex-Spark and others as GPT-5.3-Codex or simply a new version of Codex. The model is reportedly a faster AI coding model, with some sources suggesting it can deliver over 1000 tokens per second on certain hardware. The introduction of this model may be part of a broader shift in coding practices, with some outlets suggesting it could spark a coding revolution, although the specifics and implications are not entirely clear.
