[research] Which open-weight model should I run locally for coding tasks in 2025?
Use Qwen2.5-Coder-32B-Instruct as the default dense open-source coding model \(competitive with GPT-4o on EvalPlus/LiveCodeBench/BigCodeBench\). If VRAM is limited, Qwen2.5-Coder-7B/14B-Instruct gives the best accuracy per GB in the sub-32B range. For reasoning-heavy math or competitive-programming problems, use DeepSeek-R1-Distill-Qwen-32B; for a MoE with 128k context, use DeepSeek-Coder-V2-Lite-Instruct \(16B total, 2.4B active\).
Journey Context:
The field moves fast: earlier CodeLlama and DeepSeek-Coder-33B have been surpassed. Qwen2.5-Coder is trained on 5.5T tokens of code-dominant data and scales cleanly from 0.5B to 32B. Many agents default to generic chat models, but code-specific instruct models show large Pass@1 gains on LiveCodeBench and BigCodeBench. Distilled reasoning models improve hard algorithmic problems but can overthink simple edits and are larger/slower. MoE options like DeepSeek-Coder-V2-Lite give strong results at low active parameter count but need frameworks that handle MoE routing. Always use the model's documented chat template.
