Bolt.new ties bigger AI app-building allowance to training-data opt-in

Bolt.new launched Forge on September 14, offering individual Pro subscribers up to 50 times more open-model usage at no extra cost if they opt in to share build sessions for AI training. The sessions will help Arcee AI train a trillion-parameter-class open-weight model, according to the company’s launch announcement.

The expanded allowance runs through October 14, 2026, Bolt’s product guide says. Forge operates inside Bolt.new, a platform for building applications through natural-language instructions. Its allowance is separate from premium usage, with no daily limits and a hard monthly cap rather than overage charges.

The contribution extends beyond finished applications. Shared sessions include prompts, code, project files, configuration, tool calls and edit histories. Bolt says it strips secrets and personal information before the data leaves its infrastructure. Those sessions become datasets licensed to AI developers, starting with Arcee; StackBlitz, the company behind Bolt.new, may receive payment, and other developers may also license the datasets.

Users see a consent screen when switching into Forge. Returning to Standard or Max stops new collection; stopping use of previously collected content requires a request to Bolt. Teams and Enterprise workspaces are excluded from Forge and its training-data licensing. Sessions from the EEA, UK and Switzerland are also excluded from training and datasets, although users there receive the same allocation.

Arcee’s first training run is scheduled to begin in October using sessions shared during the preview. Arcee CEO Mark McQuade said in the announcement that models trained on Forge would be released publicly for downloading and running.

Forge will remain available as an experimental agent after October 14, but the expanded allowance is a preview offer. Bolt advises users to duplicate serious projects before switching them into Forge and to keep complex production work in Standard or Max.
