Bullet claims it is 30–60% faster than Claude Code and Codex Discussion.
The cited comparison number is 30–60%.
As a result, it positions Bullet as a quicker option for AI code-generation workflows, though the information provided is minimal and not enough to verify details.

Claude Fable 5 generated a complete 3D browser-based game called Raccoon Heist based solely on a 2022 tweet and concept images, including procedurally created characters, AI-generated textures, and a dynamic soundtrack. The game required 7 commits and took approximately one development session to build, with Claude independently handling design decisions, testing with Playwright, and fixing bugs discovered during playthroughs. The deployment now works as a fully functional standalone game with no runtime API calls, though the result is a functional prototype rather than a polished final product.
An essay argues that while software code will become automatically regenerated, current generative-AI approaches relying on natural language specifications lack the precision needed for full automation without human oversight. The author contends that formal logic-based specifications, rather than natural language or even semi-formal templates like EARS, are necessary to enable truly automatic code regeneration at scale. The shift would make conventional code a throwaway byproduct of formal specifications, similar to how assembly language is now rarely hand-written, allowing organizations to regenerate entire codebases when security, performance, or algorithm requirements change.
