Sakana AI released Sakana Marlin, an autonomous research assistant that takes a topic and runs up to eight hours to produce summary slides and a detailed strategy report. It uses long-horizon reasoning and multi-model control to form hypotheses, gather data, and verify findings without human input. After a closed beta with about 300 professionals, it’s now available via pay-per-use and tiered subscription plans.
