Recursive Runs Eight Agent AI Research Swarm on a Single 48GB Mac With Flint Model

marketbrief.now

Recursive released code and demos enabling an eight-agent research swarm to run locally on a single 48GB M4 Pro Mac using one shared instance of its 40B parameter Flint model. The setup builds on Recursive's Eureka Machine, an automated AI research system that helped build Flint from scratch in under four months. Flint, released under an Apache 2.0 license with a 262K token context window, achieved 54.9% on Terminal-Bench 2.1, 89.7% on SWE-bench Pro v2, and 74.2% on SWE-bench Verified.
