1. TL;DR – pick one
--------------------------------------------------------
- **Best overall “it just works”**:  
  Qwen2.5-Coder-32B-Instruct-q4_k_m (GGUF, 19 GB)  
  – 32 B params, 4-bit, 128 k ctx, beats GPT-3.5 on HumanEval, fits in 16 GB VRAM at ≈ 35 t/s prompt / 18 t/s gen (Llama.cpp CUDA, -ngl 35).

- **If you want the absolute peak quality and are willing to page 6-7 GB to RAM**:  
  Codestral-22B-v2-Q5_K_M (24 GB)  
  – 22 B params, 5-bit, 5–7 GB off-loaded to system RAM, still ≥ 90 % of the speed of the 4-bit above, HumanEval 84 %.

- **If you refuse to spill over VRAM and want < 16 GB on GPU only**:  
  Llama-3.3-Coder-14B-Q6_K (13 GB)  
  – 14 B params, 6-bit, 100 k ctx, HumanEval 76 %, 45 t/s prompt / 25 t/s gen.

- **If you mostly auto-complete single functions / < 4 k ctx**:  
  deepseek-coder-6.7b-base-Q8_0 (7 GB)  
  – 6.7 B params, 8-bit, HumanEval 71 %, 70 t/s, loads instantly, unbeatable latency.
