ollama run qwen3.5:27bBest Local LLM for Agentic Coding
Agentic coding — where the AI writes code, runs tests, reads errors, and iterates — requires a model that excels at multi-step reasoning, tool use, and long-context instruction following. Here's what to use in 2026:
Best for Agentic Coding: Qwen2.5 Coder 32B + Continue.dev
Works with Ollama backend via OpenAI-compatible API
For agent frameworks like Claude Code, Aider, Continue.dev, or Cursor (with local model support), Qwen2.5 Coder 32B is the best local backend — it follows complex multi-step instructions, supports function/tool calling, and maintains coherence across long agentic loops.
For machines with 8–16 GB RAM, DeepSeek Coder V2 Lite is the best agentic option — its MoE architecture activates only a fraction of its parameters per token, keeping it fast even during long reasoning chains.
Ollama + Continue.dev setup:
ollama run qwen2.5-coder:32b# Then in Continue.dev config: model: "qwen2.5-coder:32b", provider: "ollama"Also see: local LLM tools that support MCP and tool calling

DeepSeek R1 vs Claude Code: Local Alternative
Many developers use Claude Code for AI-assisted coding. Here's how running DeepSeek-R1 locally via Ollama compares as a free, private alternative:
| Factor | DeepSeek Local (Ollama) | Claude Code (Cloud) |
|---|---|---|
| Cost | ✅ Free (runs locally) | ❌ $20/month Claude Pro |
| Privacy | ✅ 100% local, offline | ❌ Sends code to Anthropic servers |
| Code quality (32B) | ✅ Competitive with GPT-4o | ~ Claude Sonnet still leads on hardest tasks |
| Speed | ✅ Sub-second on GPU | ~ ~50 tok/s via API |
| Context window | ✅ 128K tokens | ✅ 200K tokens |
| Agentic coding | ✅ Works with Aider, Continue.dev | ✅ Native Claude Code CLI |
| Internet / web | ❌ Offline only | ✅ Web search available |
For private codebases, sensitive projects, or teams without cloud AI budgets, running DeepSeek-R1 locally is a compelling Claude Code alternative. Start with ollama run deepseek-r1:14b.
