 3. For mathematical problems, it is advisable to include a directive in your prompt such as: "put your final answer within \boxed{}".
 4. When evaluating model performance, it is recommended to conduct multiple tests and average the results.

+## 7. Function Calling and Structured Outputs
+
+### Current Status
+- As of now, **DeepSeek R1 does not natively support function calling or structured outputs**.
+- The model is primarily optimized for **reasoning-heavy tasks** (e.g., math, code, and STEM) and follows a conversational format.
+
+### Future Plans
+- We recognize the importance of **function calling** and **structured outputs** for many use cases, such as API integrations, automation, and data extraction.
+- We are actively exploring ways to add support for these features in future updates. This includes:
+  - Extending the model’s capabilities to handle structured data formats (e.g., JSON, XML).
+  - Adding support for function calling to enable seamless integration with external tools and APIs.
+
+### Timeline
+- While we don’t have a specific release date yet, we aim to roll out these features in the **next major update**.
+- We will keep the community updated on our progress through GitHub announcements and release notes.
+
+### Workarounds for Now
+If you need structured outputs or function-like behavior in the meantime, here are some workarounds:
+1. **Post-Processing Outputs:**
+   - Use a script to parse the model’s responses into structured formats (e.g., JSON).
+   - Example:
+     ```python
+     import json
+
+     response = model.generate("Extract the following data as JSON: ...")
+     structured_data = json.loads(response)
+     ```
+
+2. **Prompt Engineering:**
+   - Design prompts to guide the model to produce outputs in a specific format.
+   - Example:
+     ```
+     Extract the following information and format it as JSON:
+     - Name: ...
+     - Age: ...
+     - Location: ...
+     ```
+
+3. **Custom Wrapper:**
+   - Build a custom wrapper around the model to simulate function calling behavior.
+   - Example:
+     ```python
+     def call_function(model, function_name, args):
+         prompt = f"Call function {function_name} with args {args} and return the result."
+         return model.generate(prompt)
+     ```
+
+### Community Feedback
+We appreciate the enthusiasm from the community (x2 + 5 and counting!). Your feedback is invaluable in shaping the future of DeepSeek R1. If you have specific use cases or feature requests related to function calling and structured outputs, please share them in this thread.
+
+### Next Steps
+- We will prioritize this feature based on community demand and provide updates as development progresses.
+- Stay tuned for announcements and feel free to contribute ideas or suggestions!
+
+Thank you for your patience and support as we work to make DeepSeek R1 even better! Let us know if you have further questions or need additional assistance.
