Grok was not a single chatbot for long. xAI introduced it in late 2023 as an assistant connected to X; by August 2026, Grok 4.6, Grok Bot, Grok Build, Grok Imagine, voice APIs, Office add-ins, and enterprise integrations had turned it into a product family built around models, APIs, media tools, voice, coding, and autonomous work.
That change began showing up in 2024 releases. Grok-1.5 brought a 128K context window, Grok-1.5V added vision, the xAI API opened to developers, and Aurora brought image generation into Grok. In 2025, Grok 3 and Grok 4 shifted attention toward reasoning, tools, coding, and voice agents.
This timeline tracks the product milestones behind that change: what Grok could do, where it was available, and when each major release opened a new model, API, tool, or platform.
