Multiple channels announced today that the stealth coding model code-supernova has been upgraded to code-supernova-1-million , expanding the context window from approximately 200,000 tokens to 1,000,000 tokens . This upgrade will be free for individual users for a limited time. Cline and Kilo Code announced that this version targets very long code bases, logs, and multi-file collaboration, making it suitable for agentic coding and long-term tasks. The Windsurf and Cursor communities also released user interface and replacement instructions, noting that after refreshing, the original supernova will be replaced by the 1-million version.
The current release is primarily through official platform posts and blogs. Details include: individual users can directly activate the new model; the model name will appear as "code-supernova-1-million" in Windsurf/Cursor; and the free access is limited in time, with the specific duration and subsequent billing subject to platform updates. Developers have already begun comparing performance in scenarios such as large-scale repository refactoring, debugging long logs, and cross-file rewriting in the 1M context.
