Nanbeige4.3 33B — Hardware Requirements & GPU Compatibility

ChatFunctions

Nanbeige4.3-33B is a 33.1-billion-parameter dense language model from Nanbeige, the flagship teacher model of the Nanbeige4.3 series, intended to anchor distillation of agentic capabilities into smaller models. It is built for agentic coding and professional cowork tasks, and Nanbeige positions it among open models in the roughly 30B class, comparing it with Qwen3.8-27B, Muse-Glimmer-30B, and Gemma4-31B. English and Chinese are the listed languages. Context length is up to 524,288 tokens (512K). It is released under the Apache 2.0 license, permitting unrestricted commercial and research use, and was published in October 2026. At 4-bit quantization the weights take roughly 20 GB, so it fits a single 24 GB GPU for short contexts, while the long context window needs considerably more memory for the KV cache.

Frequently Asked Questions

How much VRAM does Nanbeige4.3 33B need?

Nanbeige4.3 33B requires 20.6 GB of VRAM at Q4_K_M, or 67.0 GB at BF16. Full 524K context adds up to 111.2 GB (131.8 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 33.1B × 4.8 bits ÷ 8 = 19.9 GB

KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 111.9 GB (at full 524K context)

Can I run Nanbeige4.3 33B on a Mac?

Yes — MacBook Pro 14" M3 Pro (18 GB) and 108 other Macs can run Nanbeige4.3 33B, the smallest at IQ2_S. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 20.6 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio M1 Max (32 GB).

Can I run Nanbeige4.3 33B locally?

Yes — Nanbeige4.3 33B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Nanbeige4.3 33B?

At Q4_K_M, Nanbeige4.3 33B can reach ~233 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~32 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 20.6 × 0.65 = ~252 tok/s
