OpenAI's 'Predicted Outputs' Boosts GPT-4o Speed, Adds Speculative Decoding

Nov 4, 2024, 10:40 PM

OpenAI has launched a new feature called 'Predicted Outputs' that aims to significantly reduce latency and optimize costs for various applications, particularly in coding and document editing. This feature allows for faster processing by reusing known sections in tasks like code edits, with any tokens provided that are not part of the final completion being charged at completion token rates. The GPT-4o and GPT-4o-mini models now support this feature, making them 2–4 times faster than other models. Developers are excited about the potential of 'Predicted Outputs' for use cases that require low latency and fast, accurate responses, such as customer service bots, real-time collaboration tools, and interactive educational platforms. Additionally, speculative decoding is now available in the OpenAI API, and Qwen2.5 has integrated search capabilities.
