ZDTaichu5.0 9B — Hardware Requirements & GPU Compatibility
VisionFunctionsZDTaichu5.0-9B is TaichuAI's 9.8-billion-parameter multimodal foundation model, combining a Qwen3.5-9B language backbone with an NVIDIA C-RADIOv4-H vision encoder to accept text, images, and video at any resolution. Beyond general image, document, and OCR understanding, it is built for spatial reasoning (2D/3D relations, viewpoint and depth, affordances), embodied-AI planning, and multi-step agentic tool use, using an "Entropy-Gated Adaptive Recurrent Reasoning" mechanism that allocates extra recurrent computation to harder tokens. The card reports it leading spatial and agentic benchmarks among comparable 10B-scale open vision-language models. At under 10 billion parameters, it fits on a single consumer GPU once quantized. Context length is 131,072 tokens. It is released under the NVIDIA Open Model License Agreement, with the underlying Qwen3.5 component retaining its Apache 2.0 license, and was published in September 2026.

Frequently Asked Questions
- How much VRAM does ZDTaichu5.0 9B need?
ZDTaichu5.0 9B requires 6.5 GB of VRAM at Q4_K_M, or 21.6 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 9.8B × 4.8 bits ÷ 8 = 5.9 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
Q4_K_M6.5 GB- What's the best quantization for ZDTaichu5.0 9B?
For ZDTaichu5.0 9B, Q4_K_M (6.5 GB) offers the best balance of quality and VRAM usage. Q5_K_S (7.4 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XS at 3.2 GB.

- Can I run ZDTaichu5.0 9B on a Mac?
ZDTaichu5.0 9B requires at least 3.2 GB at IQ2_XS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run ZDTaichu5.0 9B locally?
Yes — ZDTaichu5.0 9B can run locally on consumer hardware. At Q4_K_M quantization it needs 6.5 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is ZDTaichu5.0 9B?
At Q4_K_M, ZDTaichu5.0 9B can reach ~743 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~101 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 ÷ 6.5 × 0.65 = ~805 tok/s
Estimated speed at Q4_K_M (6.5 GB)
~805 tok/s~101 tok/s~805 tok/s~743 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of ZDTaichu5.0 9B?
