LiveBench is a benchmark that adds new questions on a schedule, so a model is less likely to have seen the answers in training. In its current release the coding category is bug-fix tasks taken from real merged pull requests on a frozen codebase, graded deterministically: a fix that breaks existing behaviour scores 0. We read the category score as a share of points.

Role in the index

LiveBench coding carries 15% of the Vibe Coding Index. A model missing it is scored on the other benchmarks of that index. Read the methodology

Only models in our catalog are listed, and each appears once with its best published run. 43 rows were read from the source on October 21, 2026, and rows that match no catalog model are left out. Cost per task is what LiveBench reports the run spent on the category, divided by the number of tasks in it, in US dollars; LiveBench defines it the same way. Every other column is a figure the board publishes for the same run.
