+The OpenAI Responses API provides a range of [built-in tools](https://platform.openai.com/docs/guides/tools) to enrich the model's response:

+- **Web Search**: Allows models to search the web for the latest information before generating a response.
+- **MCP Servers**: Allows models to connect to remote MCP servers. Find out more about using remote MCP servers as tools [here](https://platform.openai.com/docs/guides/tools-connectors-mcp).
+- **File Search**: Allow models to search your knowledgebase from previously uploaded files for relevant information before generating a response. Refer to the [OpenAI documentation](https://platform.openai.com/docs/guides/tools-file-search) for more information.
+- **Code Interpreter**: Allows models to write and run Python code in a sandboxed environment.

 Use this option to set the probability the completion should use. Use a lower value to ignore less probable options. 
 
+### Conversation ID
+The conversation that this response belongs to. Input items and output items from this response are automatically added to this conversation after this response completes.
+
+###  Prompt Cache Key
+Use this key for caching similar requests to optimize cache hit rates.

+### Safety Identifier
+Apply an identifier to track users who may violate usage policies.

+### Service Tier
+Select the service tier that fits your needs: Auto, Flex, Default, or Priority.
+
+### Metadata
+A set of key-value pairs for storing structured information. You can attach up to 16 pairs to an object, which is useful for adding custom data that can be used for searching by the API or in the dashboard.

+### Top Logprobs
+Define an integer between 0 and 20 specifying the number of most likely tokens to return at each token position, each with an associated log probability.
+
+### Output Format
+Choose a response format: Text, JSON Schema, or JSON Object. Use of JSON Schema is recommended, if you want to receive data in JSON format.

+### Prompt
+Configure the prompt filled with a unique ID, its version, and substitutable variables.
+
+### Reasoning Effort
+Control the reasoning level of AI results: Low, Medium, or High.
