## Where it stands

- No newer code model in the registry yet.
- Weights are public under a permissive licence (Apache-2.0).

## What stands out

- Model largely developed by automated AI research: Recursive says its Eureka Machine helped develop nearly every part of Flint's model-building stack, from data and training recipes to infrastructure and inference optimization. Source: https://www.recursive.com/updates/introducing-recursive-flint
- Fast local agentic coding: 40B-total / ~2.5B-active MoE; 125+ tokens/s on an M4 Pro MacBook Pro and 150+ on RTX Spark; 74.2% SWE-bench Verified, 54.9% Terminal-Bench 2.1 (developer-reported). Source: https://huggingface.co/RecursiveSI/flint

## Notes

Open-weight coding MoE (39.8B total, ~2.5B active, 262k context). BF16 checkpoint ~80 GB serves on one B300/H200 via the bundled SGLang kit; Transformers modeling code not included at launch. Recursive recommends splitting big tasks into smaller steps. Also free on OpenCode and pi.dev (per Socher).

Quick start (model card): `hf download RecursiveSI/flint`, build the SGLang image in `sglang/`, then call the OpenAI-compatible endpoint at
`http://localhost:30000/v1` with `model="flint"`.
