Gemini 1.5 Pro (2024)
Google gave developers a one-million-token context window in its Gemini 1.5 Pro model, letting it process an entire book's worth of text or hours of video in one pass.
Google demonstrated that million-token contexts were feasible and marketed Gemini's capacity against OpenAI's smaller windows.
The one-million-token bar became the industry comparison point for long-context models.
OpenAI's million-token window matches a threshold Google set years earlier, rather than setting a new one.
