  • The forthcoming model consolidates OpenAI’s GPT-series and o-series technologies, including the o3 reasoning engine, into a single advanced architecture.
  • OpenAI plans to introduce mini and nano API variants to make GPT-5’s capabilities accessible across a wider range of devices and use cases.
  • GPT-5 is expected to incorporate video processing and support context windows exceeding 256,000 tokens for longer, more coherent interactions.
  • References to GPT-5 within Microsoft Copilot’s new Smart Mode suggest the assistant can dynamically switch between deep reasoning and fast-response modes likely powered by the update.
