Sam Altman lays out roadmap for OpenAI’s long-awaited GPT-5 model
On Wednesday, OpenAI CEO Sam Altman announced a roadmap for how the company plans to release GPT-5, the long-awaited followup to 2023’s GPT-4 AI language model that made huge waves in both tech and policy circles around the world. In a reply to a question on X, Altman said GPT-5 would be coming in “months,” suggesting a release later in 2025.
Initially, Altman explained in a long post on X, the company plans to ship GPT-4.5 (previously known as “Orion” internally) in a matter of “weeks” as OpenAI’s last non-simulated reasoning model. Simulated reasoning (SR) models like o3 use a special technique to iteratively process problems posed by users more deeply, but they are slower than conventional large language models (LLMs) like GPT-4o and not ideal for every task.
After that, GPT-5 will be a system that brings together features from across OpenAI’s current AI model lineup, including conventional AI models, SR models, and specialized models that do tasks like web search and research. “In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3,” he wrote. “We will no longer ship o3 as a standalone model.”
