ChatGPT-5.3 has been released — it is now available to all users, though currently the GPT-5.3 Instant version is in use. This update significantly enhances attentiveness and fact-checking accuracy: the model now makes fewer errors and avoids unnecessary details. Internet search has been improved — the neural network now combines external data with existing knowledge for more precise answers. Additionally, the ability to maintain context and depth of analysis has been enhanced: the model better grasps hidden meanings, retains the flow of conversation longer, and operates more consistently. The key focus of this release is reducing the number of "hallucinations" and increasing the meaningful depth of each response.
