   - GPT-3.5 has a 4096 context token limit, GPT-4 has 8K (there is a 32K one available to the public soon per OpenAI). **So if you set a big token limit in your Copilot setting, you could get this error.** Note that the prompts behind the scenes for Copilot commands can also take up tokens, so please limit your message length and max tokens to avoid this error. (For QA with Unlimited Context, use the "QA: Active Note" chain in the dropdown! Requires Copilot v2.1.0.)

+    curl https://YOUR_RESOURCE_NAME.openai.azure.com/openai/deployments/YOUR_DEPLOYMENT_NAME/completions?api-version=VERSION\
+      -H "Content-Type: application/json" \
