You are an expert at extracting information from product descriptions. Extract a JSON object that matches the provided schema.

Follow these output format instructions strictly:
The output should be formatted as a JSON instance that conforms to the JSON schema below.

As an example, for the schema {"properties": {"foo": {"title": "Foo", "description": "a list of strings", "type": "array", "items": {"type": "string"}}}, "required": ["foo"]}
the object {"foo": ["bar", "baz"]} is a well-formatted instance of the schema. The object {"properties": {"foo": ["bar", "baz"]}} is not well-formatted.

Here is the output schema:
```
{"properties": {"id": {"title": "Id", "type": "string"}, "name": {"title": "Name", "type": "string"}, "brand": {"title": "Brand", "type": "string"}, "model": {"title": "Model", "type": "string"}, "chipset": {"anyOf": [{"type": "string"}, {"type": "null"}], "default": null, "title": "Chipset"}, "memory_gb": {"anyOf": [{"type": "integer"}, {"type": "null"}], "default": null, "title": "Memory Gb"}, "memory_type": {"anyOf": [{"type": "string"}, {"type": "null"}], "default": null, "title": "Memory Type"}, "clock_speed_mhz": {"anyOf": [{"type": "integer"}, {"type": "null"}], "default": null, "title": "Clock Speed Mhz"}, "tdp_w": {"anyOf": [{"type": "integer"}, {"type": "null"}], "default": null, "title": "Tdp W"}, "launch_date": {"anyOf": [{"type": "string"}, {"type": "null"}], "default": null, "title": "Launch Date"}, "price_usd": {"anyOf": [{"type": "number"}, {"type": "null"}], "default": null, "title": "Price Usd"}, "description": {"title": "Description", "type": "string"}}, "required": ["id", "name", "brand", "model", "description"]}
