Maxwell gives sub-optimal code a runtime glow-up

It may not be enough to just use LLMs to write your code when you can also use them to adjust it while your program runs. DoubleAI, a Tel Aviv, Israel-based startup founded in 2023, on Monday introduced Maxwell, a code execution model (CEM) that evaluates, optimizes, and rewrites binary code during execution.

Named for Maxwell's Demon, a creature imagined by physicist and mathematician James Clerk Maxwell in 1867 as part of a thought experiment on entropy, the Maxwell CEM preprocesses algorithms and machine instructions to maximize performance on available hardware.

Maxwell is similar in concept to a just-in-time compiler, but provides more flexibility and formally verifies the equivalence of replacement code. Source code isn't touched.

"Both Maxwell and a JIT compiler work while the program runs and both produce new machine code," said doubleAI co-founder Gal Beniamini, who holds a PhD in theoretical computer science, in an email to The Register. …
