 ### With Local Models (Ollama + Qwen3-Coder)
 
-We patched the source to add `LOCAL_MODEL_BASE_URL` — routes only model API calls to your local proxy while letting auth/startup use Anthropic's servers normally.
+Run Claude Code's UI with a local open-source model. The included `ollama-proxy.mjs` translates between the Anthropic API format and Ollama, routing model calls locally while auth goes to Anthropic normally.
 
-**Requirements:** [Ollama](https://ollama.com) + [litellm](https://github.com/BerriAI/litellm) + a Claude subscription (for auth)
+**Requirements:** Node.js 18+, [Ollama](https://ollama.com), a Claude subscription (for auth only)
 
 ```bash
-# Step 1: Pull a model with 128K+ context (required for Claude Code's system prompt)
+# Step 1: Pull a model with 128K+ context
 ollama pull qwen3-coder:30b
 
-# Step 2: Create litellm config that maps Claude's model name to your local model
-cat > litellm-config.yaml << 'CONF'
-model_list:
-  - model_name: "claude-sonnet-4-20250514"
-    litellm_params:
-      model: "ollama/qwen3-coder:30b"
-      num_ctx: 65536
-litellm_settings:
-  drop_params: true
-CONF
+# Step 2: Start the proxy (included in this repo)
+node ollama-proxy.mjs
 
-# Step 3: Start litellm proxy (needs Python 3.10+)
-pip install 'litellm[proxy]'
-litellm --config litellm-config.yaml --port 8080
-
-# Step 4: Run Claude Code (in another terminal)
-LOCAL_MODEL_BASE_URL=http://localhost:8080 node cli.js
+# Step 3: Run Claude Code (in another terminal)
+ANTHROPIC_BASE_URL=http://localhost:9090 node cli.js
 ```
 
-Claude Code authenticates with Anthropic normally (you need a subscription), but all model inference runs locally on Qwen3-Coder via Ollama. Works with any model that has 128K+ context — qwen3-coder, deepseek-r1, llama4, etc.
+The proxy terminal shows color-coded routing:
+- 🟢 `[OLLAMA]` — model calls going to your local Qwen3-Coder
+- 🟡 `[ANTHROPIC]` — auth/config calls going to Anthropic
+
+**How it works:** Claude Code's bundled `cli.js` uses the Anthropic SDK which reads `ANTHROPIC_BASE_URL`. The proxy intercepts `/v1/messages` (model API) and translates them to Ollama's format, while passing everything else (auth, bootstrap, feature flags) through to `api.anthropic.com`.
+
+**To change the model**, edit line 7 in `ollama-proxy.mjs`. Works with any Ollama model that has 128K+ context — `qwen3-coder`, `qwen3.5`, `deepseek-r1:32b`, `llama4`, etc.
