Bend 2, a language for the AI coding era that uses formal verification, falls into a "vibe-coding trap" by reinventing concepts from formal verification without acknowledging the existing field. The article demonstrates that Bend's demo requires 58 lines of specification and 442 lines of proof, whereas SPARK, an established formal verification language, accomplishes the same goal in significantly less code.
Bend is a programming language designed for the post-AGI era that combines C-speed performance with GPU parallelism and Lean-style proof checking. It enables developers to specify immutable laws (LAWS.bend) that AI agents must satisfy when writing code, ensuring bugs cannot be merged by making violations mathematically impossible to prove.
Bend is a programming language designed for the post-AGI era that compiles to native code with C-level performance on single cores and up to 100x speedup on GPUs through automatic parallelization. It uses proof-based type checking similar to Lean and includes a LAWS system that allows developers to declare mathematical invariants that AIs must satisfy, making bugs mathematically impossible to merge.
