Deep Tide TechFlow News, March 4 — OpenAI has released the GPT-5.3 Instant version, focusing on improving everyday conversation experiences. The new version significantly reduces unnecessary refusals and overly cautious responses, making conversations more direct and effective.

In high-risk fields such as medicine, law, and finance, the error rate when using web searches has decreased by 26.8%, and when relying solely on internal knowledge, the error rate has decreased by 19.7%. Additionally, the model performs better in creative writing, capable of producing more emotionally resonant and imaginative content. GPT-5.3 Instant is now available to all ChatGPT users, and developers can access it via API with the name “gpt-5.3-chat-latest.”
