AI benchmarking

Latent Space published a new tracker measuring which products AI models recommend across 161 categories, running 6 prompt variations against 7 frontier models. The analysis finds strong self-referential bias — models favor their own company's products — alongside 28 categories where every model surveyed converges on the same top pick.

Artificial Analysis has launched Optima, a platform that lets users build custom AI benchmarks using their own data, workflows, or use-case descriptions. Unlike public benchmarks, Optima compares models on cost per task and time per task in addition to quality.
