Vibe coding`, a relatively new concept, has emerged in the developer community, referring to AI-assisted workflows where developers let models generate full chunks of their app and roll with it. However, as projects grow, this approach can hit its limits, leading to bugs, untraceable changes, and introduced dependencies. To address this, Cursor Tab has been developed, an "autocomplete on steroids" feature that enables "tab coding," a human-AI collaboration approach where developers guide the AI through intentional implementation steps. Tab coding uses predictive coding and zero-entropy edits to reduce repetition, maximize predictive intelligence, and enhance user experience by providing intuitive UI elements. The technology combines advanced AI and optimization techniques, including hierarchical model architecture, low latency optimizations, and intelligent processing methods, such as speculative edits and caching-aware prompting. By empowering developers beyond vibe coding, Tab aims to maintain agency while eliminating implementation friction, providing knowledge rather than just code.
