Flint-40B-A2B: AI-Built MoE Coding Model Hits 125 tok/s on MacBook Pro

Recursive_SI's first model Flint-40B-A2B, a 40B MoE model activating 2.5B parameters per token, was built in under four months using the automated Eureka Machine system. It achieves state-of-the-art local coding performance on benchmarks like SWE-Bench while running at 125+ tokens/sec on MacBook Pro M4 Pro and 150+ tokens/sec on NVIDIA RTX Spark, with open weights on Hugging Face under Apache 2.0.
