High-End Local Model Use Hits Practical VRAM Limits
Reddit users report that 16GB is the effective upper limit for most people's consumer GPUs, with even 12GB considered a luxury for many outside niche high-end setups. Larger cards (24GB+) are seen as financially out of reach. [1]
Recent Advances Enable Larger Models on 16GB Cards
Recent developments make agentic coding feasible on 16GB GPUs, such as running quantized Qwen 27B models, but users note fundamental limits on model scale and world knowledge due to VRAM. [1]

“there's going to be a hard limit on how much world knowledge these smaller models will have”
