You can't just install the extension and expect it to magically find your local model. You need a provider. I use Ollama because it handles the memory management without me having to dive into CUDA environment variables every time I reboot.\n\nFirst, pull the model. Open your terminal and run:`ollama run qwen2.5-coder:32b`\n\nIf you're on a laptop with 16GB of RAM, 32B will crawl. Use the 7B version. It's surprisingly punchy for its size.\n\nOnce Ollama is humming in the background, you have to tell Continue where to look. Open the Continue config (Cmd+Shift+P -> \"Continue: Open config.json\"). Your `models`\n\narray should look like this:\n\n```\n{\n  \"title\": \"Qwen 32B Local\",\n  \"model\": \"qwen2.5-coder:32b\",\n  \"provider\": \"ollama\"\n}\n```\n\nI spent three hours last Thursday debugging a \"Connection Refused\" error only to realize I had a firewall rule blocking port 11434. Check your ports.\n\n### Tab-autocomplete vs. Chat: The dual-model strategy\n\nHere is the part most tutorials skip: do not use the same model for the chat sidebar and the inline autocomplete.\n\nIf you use a 32B model for autocomplete, your [cursor](/en/tags/cursor/) will lag. It’s a nightmare. You want a tiny, fast model for the \"ghost text\" and a heavy hitter for the architectural questions. This is where the [PromptCube homepage](/en/) community usually suggests a split setup.\n\n| Task | Recommended Model | Why? |\n\n| :--- | :--- | :--- |\n\n| Inline Autocomplete | qwen2.5-coder:1.5b | < 20ms latency |\n\n| Complex Refactoring | qwen2.5-coder:32b | High reasoning capacity |\n\n| Quick Unit Tests | qwen2.5-coder:7b | Balanced speed/logic |\n\nTo set this up, add a `tabAutocompleteModel`\n\nsection to your `config.json`\n\n:\n\n```\n\"tabAutocompleteModel\": {\n  \"title\": \"Qwen 1.5B\",\n  \"provider\": \"ollama\",\n  \"model\": \"qwen2.5-coder:1.5b\"\n}\n```\n\nNow the ghost text snaps into place instantly, but you still have the 32B beast available when you need to rewrite a legacy React component without breaking five other things.\n\n### Fixing the \"Context Window\" hallucination\n\nLocal LLMs have a habit of \"forgetting\" the top of your file if the context window isn't configured right. By default, some local providers truncate your code.\n\nIf Qwen starts suggesting variables that don't exist or forgetting your imports, you need to explicitly set the `contextLength`\n\n. For Qwen2.5-Coder, you can push this pretty far, but your VRAM is the limiting factor.\n\nTry adding this to your model config:`\"contextLength\": 32000`\n\nIf your IDE starts crashing or Ollama restarts, dial it back to 16k.\n\n### Why this beats a cloud subscription\n\nI'm tired of the \"latency lottery\" with cloud APIs. When you're in a flow state, a 2-second delay for a suggestion is an eternity. Local Qwen is instant. Plus, no one is training their next frontier model on my proprietary API keys or messy internal company logic.\n\nThe real power comes when you start indexing your codebase. Continue creates a local embeddings index. When you use `@Codebase`\n\nin the chat, it doesn't send your whole project to a server; it searches your local index and feeds the relevant snippets to Qwen.\n\nIf you're struggling with how to structure these prompts to get cleaner code, checking out some proven [Resources](/en/category/resources/) on prompt engineering for local models is a lifesaver. I found that telling Qwen to \"be concise and omit explanations\" reduces the token output and speeds up the response time by about 30%.\n\n### The \"It's not working\" checklist\n\nIf your Continue extension setup is still acting up, check these three things:\n\n1. **Ollama Version:** Are you on the latest? Qwen2.5 support was added recently. Update or you'll get garbage output.\n\n2. **VRAM Overhead:** Open your activity monitor. If your GPU is at 98%, your OS is swapping to disk, and your \"local\" AI will feel slower than GPT-4.\n\n3. **The JSON comma:** A single missing comma in `config.json`\n\nkills the whole extension. Use a JSON validator.\n\nFor those who want to automate the boring parts of their dev cycle, integrating these local models into specific [Workflows](/en/category/workflows/) is the next step. I've started using local Qwen to pre-scan my PRs for silly mistakes before I even push to GitHub.\n\n### Joining the conversation\n\nSetting up local AI is a bit of a rabbit hole. One day you're just trying to get a snippet of code, the next you're optimizing KV cache quantization.\n\nThe PromptCube community is where this actually happens. It's not just a list of prompts; it's a place where developers trade `config.json`\n\nfiles and benchmark different quantizations (Q4_K_M vs Q8_0) to find the sweet spot between intelligence and speed.\n\nTo join, just head to the site and jump into the forums. It's better than screaming into the void of a generic Discord server because you're talking to people who actually care about the difference between a 7B and a 32B parameter model.\n\n[Next GPT-5.6 vs Claude Fable 5: Which Wins for Physical AI? →](/en/threads/4268/)\n\n## All Replies （0）\n\nNo replies yet — be the first!", "url": "https://wpnews.pro/news/continue-extension-setup-qwen-coder-local-setup", "canonical_source": "https://promptcube3.com/en/threads/4319/", "published_at": "2026-07-29 23:33:32+00:00", "updated_at": "2026-07-29 23:38:35.922439+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "developer-tools", "ai-tools"], "entities": ["Qwen2.5-Coder-32B-Instruct", "Ollama", "Continue", "GPT-4o", "PromptCube"], "alternates": {"html": "https://wpnews.pro/news/continue-extension-setup-qwen-coder-local-setup", "markdown": "https://wpnews.pro/news/continue-extension-setup-qwen-coder-local-setup.md", "text": "https://wpnews.pro/news/continue-extension-setup-qwen-coder-local-setup.txt", "jsonld": "https://wpnews.pro/news/continue-extension-setup-qwen-coder-local-setup.jsonld"}}
