Recursive Ships Flint: a 39.8B MoE Coding Model With 2.5B Active Params and Its Own Inference Engine

BerryBlush_Rogers691 · reddit · 2026-10-22

Recursive released Flint, an Apache 2.0 coding-focused model (39.8B total / 2.5B active params, 256K context) supporting reasoning and multi-turn tool use, plus rec, a local inference engine integrated with pi and OpenCode that reportedly hits 1.4–2.6× the generation throughput of llama.cpp on an M4 Pro (prefill excluded).

Caveats: rec currently requires M4 Pro/M5 Pro/M5 Max with ≥48GB unified memory, is optimized for a single session, and official GGUF downloads remain large. The poster questions whether the throughput gain matters in full coding tasks once repo reading, tool results, and test runs are included, calling for a like-for-like rec vs llama.cpp benchmark on long conversations.
