Frequently Asked Questions
- How much VRAM does ERNIE 4.5 0.3B PT need?
ERNIE 4.5 0.3B PT requires 1.0 GB of VRAM at BF16. Full 131K context adds up to 1.2 GB (2.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 361M × 16 bits ÷ 8 = 0.7 GB
KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 1.5 GB (at full 131K context)
VRAM usage by quantization
BF161.0 GBBF16 + full context2.2 GB- Can I run ERNIE 4.5 0.3B PT on a Mac?
ERNIE 4.5 0.3B PT requires at least 1.0 GB at BF16, 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 ERNIE 4.5 0.3B PT locally?
Yes — ERNIE 4.5 0.3B PT can run locally on consumer hardware. At BF16 quantization it needs 1.0 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is ERNIE 4.5 0.3B PT?
At BF16, ERNIE 4.5 0.3B PT can reach ~2803 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~630 tok/s. 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 ÷ 1.0 × 0.55 = ~2803 tok/s
Estimated speed at BF16 (1.0 GB)
~2803 tok/s~630 tok/s~2095 tok/s~1733 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of ERNIE 4.5 0.3B PT?
