Can I run Cydonia 24B V4.3 locally?

Yes — Cydonia 24B V4.3 can run locally on consumer hardware. At Q4_K_M quantization it needs 14.9 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Cydonia 24B V4.3?

At Q4_K_M, Cydonia 24B V4.3 can reach ~196 tok/s on AMD Instinct MI300X. On NVIDIA GeForce RTX 4090: ~44 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 MI300X5300 ÷ 14.9 × 0.55 = ~196 tok/s

Estimated speed at Q4_K_M (14.9 GB)

~196 tok/s
~44 tok/s
~147 tok/s
~121 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
