LocalLLaMA debates best 16GB VRAM coding model

A Reddit user asks for the best fully GPU-offloaded LLM on an RX 7800 XT with 16 GB VRAM, currently running `gpt-oss:20b` in Ollama at roughly 14.7 GB. The thread focuses on whether larger options like Qwen 27B can be made to fit via quantization, reduced context, Linux overhead savings, and other inference optimizations for agentic coding workloads.

// ANALYSIS

The post reflects a common 2026 local-AI constraint: VRAM, not raw compute, is still the main bottleneck for agent-style coding setups on consumer GPUs.

–The user already demonstrates near-max utilization with a 20B-class quantized model, so gains likely come from model-choice tradeoffs rather than simple tuning.
–The real decision is context length and quality versus parameter count, especially for tool-using agent workflows.
–AMD + ROCm users continue to optimize aggressively to stay fully on-GPU instead of accepting CPU offload latency.
