+# Instrukcja budowania dla Intel Xeon (bez AVX) + NVIDIA GPU (MX Linux)
+
+Ten build naprawia błąd `Illegal instruction` na starszych procesorach i wymusza użycie CUDA.
+
+## Wymagania
+* Zainstalowane `cuda-toolkit` (bez sterowników, jeśli już są w systemie).
+* Pobrane repozytorium z `git submodule update --init --recursive`.
+
+## 1. Symlinki (Naprawa ścieżek MX Linux)
+MX Linux trzyma CUDA w niestandardowym miejscu. Wykonaj raz:
+```bash
+sudo mkdir -p /usr/local/cuda
+sudo ln -sFn /usr/lib/cuda/include /usr/local/cuda/include
+sudo ln -sFn /usr/lib/x86_64-linux-gnu/nvidia/current /usr/local/cuda/lib64
+```
+
+```bash
+# Wyczyść stare
+rm -rf build
+
+# Konfiguracja
+cmake -B build \
+    -DOLLAMA_CUDA=ON \
+    -DOLLAMA_VULKAN=OFF \
+    -DGGML_VULKAN=OFF \
+    -DCMAKE_DISABLE_FIND_PACKAGE_Vulkan=TRUE
+
+# Kompilacja (1 wątek dla stabilności przy OC)
+cmake --build build -j1
+
+# Zbudowanie pliku wykonywalnego
+go build .
+```

+```bash
+sudo mv ollama /usr/bin/ollama

 # Ollama
 
+W przypadku xeon 5675 przeczytaj plik NO_AVX_GUIDE.md!!
+Możesz zastosować też build_custom.sh dla automatycznego FIX
+
 Get up and running with large language models.

----
-title: Anthropic compatibility
----
-
-Ollama provides compatibility with the [Anthropic Messages API](https://docs.anthropic.com/en/api/messages) to help connect existing applications to Ollama, including tools like Claude Code.
-
-## Recommended models
-
-For coding use cases, models like `glm-4.7:cloud`, `minimax-m2.1:cloud`, and `qwen3-coder` are recommended.
-
-Pull a model before use:
-```shell
-ollama pull qwen3-coder
-ollama pull glm-4.7:cloud
-```
-
-## Usage
-
-### Environment variables
-
-To use Ollama with tools that expect the Anthropic API (like Claude Code), set these environment variables:
-
-```shell
-export ANTHROPIC_BASE_URL=http://localhost:11434
-export ANTHROPIC_API_KEY=ollama  # required but ignored
-```
-
-### Simple `/v1/messages` example
-
-<CodeGroup dropdown>
-
-```python basic.py
-import anthropic
-

-    base_url='http://localhost:11434',

-## Using with Claude Code
-
-[Claude Code](https://code.claude.com/docs/en/overview) can be configured to use Ollama as its backend:
-
-```shell
-ANTHROPIC_BASE_URL=http://localhost:11434 ANTHROPIC_API_KEY=ollama claude --model qwen3-coder
-```
-
-Or set the environment variables in your shell profile:
-
-```shell
-export ANTHROPIC_BASE_URL=http://localhost:11434
-export ANTHROPIC_API_KEY=ollama
-```
-
-Then run Claude Code with any Ollama model:
-
-```shell
-# Local models
-claude --model qwen3-coder
-claude --model gpt-oss:20b
-
-# Cloud models
-claude --model glm-4.7:cloud
-claude --model minimax-m2.1:cloud
-```

-## Models
-
-Ollama supports both local and cloud models.
-
-### Local models
-
-Pull a local model before use:
-
-```shell
-ollama pull qwen3-coder
-```
-
-Recommended local models:
-- `qwen3-coder` - Excellent for coding tasks
-- `gpt-oss:20b` - Strong general-purpose model
-
-### Cloud models
-
-Cloud models are available immediately without pulling:
-
-- `glm-4.7:cloud` - High-performance cloud model
-- `minimax-m2.1:cloud` - Fast cloud model
-
-### Default model names
-
-For tooling that relies on default Anthropic model names such as `claude-3-5-sonnet`, use `ollama cp` to copy an existing model name:
-
-```shell
-ollama cp qwen3-coder claude-3-5-sonnet
-```
-
-Afterwards, this new model name can be specified in the `model` field:
-
-```shell
-curl http://localhost:11434/v1/messages \
-    -H "Content-Type: application/json" \
-    -d '{
-        "model": "claude-3-5-sonnet",
-        "max_tokens": 1024,
-        "messages": [
-            {
-                "role": "user",
-                "content": "Hello!"
-            }
-        ]
-    }'
-```
-
-## Differences from the Anthropic API
-
-### Behavior differences
-
-- API key is accepted but not validated
-- `anthropic-version` header is accepted but not used
-- Token counts are approximations based on the underlying model's tokenizer
-
-### Not supported
-
-The following Anthropic API features are not currently supported:
-
-| Feature | Description |
-|---------|-------------|
-| `/v1/messages/count_tokens` | Token counting endpoint |
-| `tool_choice` | Forcing specific tool use or disabling tools |
-| `metadata` | Request metadata (user_id) |
-| Prompt caching | `cache_control` blocks for caching prefixes |
-| Batches API | `/v1/messages/batches` for async batch processing |
-| Citations | `citations` content blocks |
-| PDF support | `document` content blocks with PDF files |
-| Server-sent errors | `error` events during streaming (errors return HTTP status) |
-
-### Partial support
-
-| Feature | Status |
-|---------|--------|
-| Image content | Base64 images supported; URL images not supported |
-| Extended thinking | Basic support; `budget_tokens` accepted but not enforced |

-title: Claude Code
----
-
-## Install
-
-Install [Claude Code](https://code.claude.com/docs/en/overview):
-
-<CodeGroup>
-
-```shell macOS / Linux
-curl -fsSL https://claude.ai/install.sh | bash
-```
-
-```powershell Windows
-irm https://claude.ai/install.ps1 | iex
-```
-
-</CodeGroup>
-
-## Usage with Ollama
-
-Claude Code connects to Ollama using the Anthropic-compatible API.
-
-1. Set the environment variables:
-
-```shell
-export ANTHROPIC_BASE_URL=http://localhost:11434
-export ANTHROPIC_API_KEY=ollama
-```
-
-2. Run Claude Code with an Ollama model:
-
-```shell
-claude --model qwen3-coder
-```
-
-Or run with environment variables inline:
-
-```shell
-ANTHROPIC_BASE_URL=http://localhost:11434 ANTHROPIC_API_KEY=ollama claude --model qwen3-coder
-```
-
-## Connecting to ollama.com
-
-1. Create an [API key](https://ollama.com/settings/keys) on ollama.com
-2. Set the environment variables:
-
-```shell
-export ANTHROPIC_BASE_URL=https://ollama.com
-export ANTHROPIC_API_KEY=<your-api-key>
-```
-
-3. Run Claude Code with a cloud model:
-
-```shell
-claude --model glm-4.7:cloud
-```
-
-## Recommended Models
-
-### Cloud models
-- `glm-4.7:cloud` - High-performance cloud model
-- `minimax-m2.1:cloud` - Fast cloud model
-- `qwen3-coder:480b` - Large coding model
-
-### Local models
-- `qwen3-coder` - Excellent for coding tasks
-- `gpt-oss:20b` - Strong general-purpose model
