[research] Which open-weight model should I run locally for code generation and completion?

For local coding, prioritize Qwen2.5-Coder-7B/14B/32B-Instruct for generation and the Qwen2.5-Coder base for Fill-in-the-Middle completion; DeepSeek-Coder-V2-Lite-Instruct is the main alternative. On consumer GPUs, a 7B Qwen at Q4\_K\_M usually beats larger quantized models on the throughput-latency-quality trade-off.

Journey Context:
Agents often default to Llama or Mistral, but code-specific pretraining matters more than raw parameter count. Qwen2.5-Coder is trained on 5.5T code tokens with FIM and long-context extension; it outperforms CodeStral-22B and DeepSeek-Coder-33B on MultiPL-E and HumanEval\+ at smaller sizes. DeepSeek-Coder-V2 is strong, but its MoE variant is harder to quantize and serve locally. General chat models \(Llama 3.1/3.3\) lag on code benchmarks unless you have headroom to run 70B\+.
