+# Cortecs
+
+## Overview
+
+| Property | Details |
+|-------|-------|
+| Description | Cortecs is an EU sovereign LLM router serving open-weight and frontier models over OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages APIs. |
+| Provider Route on LiteLLM | `cortecs/` |
+| Link to Provider Doc | [Cortecs Documentation ↗](https://docs.cortecs.ai) |
+| Base URL | `https://api.cortecs.ai/v1` |
+| Supported Operations | [`/chat/completions`](#usage---litellm-python-sdk), [`/responses`](#responses-api), [`/messages`](#anthropic-messages-api) |
+
+<br />
+<br />
+
+**We support ALL Cortecs models, just set `cortecs/` as a prefix when sending requests**
+
+## Available Models
+
+Cortecs routes to a live catalog of models, for example `cortecs/gpt-6-sol`. The full catalog is listed at `GET https://api.cortecs.ai/v1/models` and any model id it returns works with the `cortecs/` prefix. LiteLLM does not ship Cortecs pricing yet (Cortecs bills in EUR from its catalog), so for spend tracking pass `input_cost_per_token` and `output_cost_per_token` in `litellm_params`.
+
+## Required Variables
+
+```python showLineNumbers title="Environment Variables"
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key, get one at https://cortecs.ai
+```
+
+`CORTECS_API_BASE` can be set to override the default base URL.
+
+## Usage - LiteLLM Python SDK
+
+### Non-streaming
+
+```python showLineNumbers title="Cortecs Non-streaming Completion"
+import os
+import litellm
+from litellm import completion
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+messages = [{"content": "Hello, how are you?", "role": "user"}]
+
+# Cortecs call
+response = completion(
+    model="cortecs/gpt-6-sol",
+    messages=messages
+)
+
+print(response)
+```
+
+### Streaming
+
+```python showLineNumbers title="Cortecs Streaming Completion"
+import os
+import litellm
+from litellm import completion
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+messages = [{"content": "Write a short story about AI", "role": "user"}]
+
+# Cortecs call with streaming
+response = completion(
+    model="cortecs/gpt-6-sol",
+    messages=messages,
+    stream=True
+)
+
+for chunk in response:
+    print(chunk)
+```
+
+### Function Calling
+
+```python showLineNumbers title="Cortecs Function Calling"
+import os
+import litellm
+from litellm import completion
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+tools = [{
+    "type": "function",
+    "function": {
+        "name": "get_weather",
+        "description": "Get the current weather in a location",
+        "parameters": {
+            "type": "object",
+            "properties": {
+                "city": {
+                    "type": "string",
+                    "description": "The city, e.g. San Francisco"
+                }
+            },
+            "required": ["city"]
+        }
+    }
+}]
+
+messages = [{"role": "user", "content": "What's the weather in San Francisco?"}]
+
+response = completion(
+    model="cortecs/gpt-6-sol",
+    messages=messages,
+    tools=tools,
+    tool_choice="auto"
+)
+
+print(response)
+```
+
+### Structured Output
+
+```python showLineNumbers title="Cortecs JSON Schema Output"
+import os
+from litellm import completion
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+response = completion(
+    model="cortecs/gpt-6-sol",
+    messages=[{"role": "user", "content": "The city is San Francisco"}],
+    response_format={
+        "type": "json_schema",
+        "json_schema": {
+            "name": "city",
+            "strict": True,
+            "schema": {
+                "type": "object",
+                "properties": {"city": {"type": "string"}},
+                "required": ["city"],
+                "additionalProperties": False,
+            },
+        },
+    },
+)
+
+print(response)
+```
+
+### Responses API
+
+Cortecs serves the OpenAI Responses API natively, so `litellm.responses` sends the request straight to `https://api.cortecs.ai/v1/responses`.
+
+```python showLineNumbers title="Cortecs Responses API"
+import os
+import litellm
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+response = litellm.responses(
+    model="cortecs/gpt-6-sol",
+    input="Say hello",
+)
+
+print(response.output_text)
+```
+
+### Anthropic Messages API
+
+Cortecs also serves the Anthropic Messages API natively, so `litellm.anthropic.messages.acreate` sends the request straight to `https://api.cortecs.ai/v1/messages`.
+
+```python showLineNumbers title="Cortecs Anthropic Messages API"
+import asyncio
+import os
+import litellm
+
+os.environ["CORTECS_API_KEY"] = ""  # your Cortecs API key
+
+async def main():
+    response = await litellm.anthropic.messages.acreate(
+        model="cortecs/gpt-6-sol",
+        messages=[{"role": "user", "content": "Say hello"}],
+        max_tokens=64,
+    )
+    print(response["content"][0]["text"])
+
+asyncio.run(main())
+```
+
+## Usage - LiteLLM Proxy Server
+
+```yaml showLineNumbers title="config.yaml"
+model_list:
+  - model_name: gpt-6-sol
+    litellm_params:
+      model: cortecs/gpt-6-sol
+      api_key: os.environ/CORTECS_API_KEY
+```
+
+A deployment configured this way serves all three endpoints on the proxy: `/v1/chat/completions`, `/v1/responses`, and `/v1/messages`.
