Best quant that fits each setup, with estimated generation speed from memory bandwidth. Real speed depends on the runtime, context length and settings.
Dense 33.1B model for agentic coding and office tasks, 512K (524,288-token) context, BF16 weights. Posted Oct 23, 2026. Nanbeige's own benchmarks put it ahead of Qwen3.8 27B on most agentic coding tests but slightly behind on SWE-Bench Pro (vendor-reported).
FAQ
How much VRAM does Nanbeige4.3 33B need?
About 21 GB at Q4, 25 GB at Q5 and 37 GB at Q8, including about 1.5 GB headroom. These are estimates from the parameter count on the official model card.
Can Nanbeige4.3 33B run on 8GB of VRAM?
Not fully on the GPU. At Q4 it needs about 21 GB; partial CPU offload works but is much slower.
Can Nanbeige4.3 33B run on a Mac?
Yes. Mac 48GB (M4 Pro), Mac 128GB (M4 Max) can run it.
Which quant of Nanbeige4.3 33B should I use?
Use the highest quant that fits with room to spare: Q8 is near full quality, Q5 is a good balance, and Q4 is the smallest that usually keeps quality acceptable.
