Here we go! Purpose built AI generated LLMs!
Then AI helped optimize the code that runs it.
Recursive released Flint, a new coding/agent model designed specifically for fast local inference.
Beats Qwen3.5/3.6/3.8 in some coding benchmarks!
Stats …
🧠 39.8B total parameters
⚡ only ~2.5B active/token
📚 262K documented context
🤖 reasoning + tool use
🔓 Apache 2.0
And there are official GGUFs:
🟢 NVIDIA NVFP4 → 22.9GB
🍎 Apple INT4 → 26.0GB
Recursive recommends 48GB-class memory for these local builds, so think:
🍎 48GB+ Apple Silicon
🟢 48GB+ NVIDIA
⚡ 64GB RTX Spark
Recursive reports its optimized runtime at
🍎 M4 Pro → >125 TPs
🟢 64GB RTX Spark → >150 TPs
And WIRED’s Will Knight actually ran Flint locally on a 48GB Mac and reported it was fast and successfully handled the coding jobs he tried.
Side Note: Recursive built Flint using its Eureka Machine, an automated AI research system that helped
🧩 design the architecture
🧪 develop training recipes
⚙️ optimize infrastructure
💻 write hardware-specific inference kernels
Nvidia says those specialized kernels improved Flint’s RTX Spark generation performance by 55% wo changing the model weights.
Recursive-reported coding results
SWE-bench Verified → 74.2
SWE-bench Pro v2 → 89.7
Terminal-Bench 2.1 → 54.9
LiveCodeBench v6 → 80.3
So this isn’t merely AI writing more AI code.
