Which GPUs Can Run Vicuna 13B Delta V0?
FP16 · 28.6 GBVicuna 13B Delta V0 (FP16) requires 28.6 GB of VRAM to load the model weights. For comfortable inference with headroom for KV cache and system overhead, 38+ GB is recommended. 1 GPU can run it, including NVIDIA GeForce RTX 5090.
All compatible consumer-level GPUs are running near their VRAM limit. You may also want to consider professional GPUs (e.g., NVIDIA A100, H100) which offer significantly more VRAM. For more headroom and better throughput, consider a multi-GPU configuration with tensor parallelism (supported by tools like vLLM, llama.cpp, or text-generation-inference).

Frequently Asked Questions
- How much VRAM does Vicuna 13B Delta V0 need?
Vicuna 13B Delta V0 requires 28.6 GB of VRAM at FP16.
VRAM = Weights + KV Cache + Overhead
Weights = 13B × 16 bits ÷ 8 = 26 GB
KV Cache + Overhead ≈ 2.6 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
FP1628.6 GB- Can I run Vicuna 13B Delta V0 on a Mac?
Vicuna 13B Delta V0 requires at least 28.6 GB at FP16, 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 Vicuna 13B Delta V0 locally?
Yes — Vicuna 13B Delta V0 can run locally on consumer hardware. At FP16 quantization it needs 28.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Vicuna 13B Delta V0?
At FP16, Vicuna 13B Delta V0 can reach ~102 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: AMD Instinct MI300X → 5300 ÷ 28.6 × 0.55 = ~102 tok/s
Estimated speed at FP16 (28.6 GB)
~102 tok/s~76 tok/s~63 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Vicuna 13B Delta V0?
At FP16, the download is about 26.00 GB.
- Which GPUs can run Vicuna 13B Delta V0?
1 consumer GPU can run Vicuna 13B Delta V0 at FP16 (28.6 GB). Top options include NVIDIA GeForce RTX 5090.
- Which devices can run Vicuna 13B Delta V0?
15 devices with unified memory can run Vicuna 13B Delta V0 at FP16 (28.6 GB), including Mac Mini M4 (32 GB), Mac Mini M4 Pro (48 GB), Mac Pro M2 Ultra (192 GB), Mac Studio M2 Ultra (192 GB).
