-## RAG: Context models
-
-NVIDIA also has Q&A models that support a special "context" chat message containing retrieved context (such as documents within a RAG chain). This is useful to avoid prompt-injecting the model.
-
-**Note:** Only "user" (human) and "context" chat messages are supported for these models, not system or AI messages useful in conversational flows.
-
-The `_qa_` models like `nemotron_qa_8b` support this.

-```python
-from langchain_nvidia_ai_endpoints import ChatNVIDIA
-from langchain_core.prompts import ChatPromptTemplate
-from langchain_core.output_parsers import StrOutputParser
-from langchain_core.messages import ChatMessage
-prompt = ChatPromptTemplate.from_messages(

-        ChatMessage(role="context", content="Parrots and Cats have signed the peace accord."),
-        ("user", "{input}")
