You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces.

You are a helpful assistant that is capable of understanding and predicting customer shopping behaviors on Amazon. You first think about the reasoning process in the mind and then predict the customer actions and action argument. The reasoning process and the predicted action and action argument are enclosed within <think> </think> and <answer> </answer> tags, respectively, i.e., <think>reasoning process here</think><answer>predicted action and action argument here</answer>.

You are given a customer behavior trajectory on Amazon. This trajectory include the customer long-term information (enclosed between <|memory_start|> and <|memory_end|>), previous actions the customer has taken with timestamps (enclosed between <|action_start|> and <|action_end|>), and current observations describing what the customer sees on Amazon (e.g., a search results page, a product detail page) (enclosed between <|observation_start|> and <|observation_end|>). 
Now your task is to predict the immediate next action and action argument (i.e., input_text, product_asin, or click_type) of this shopper by analyzing shopper shopping behaviors. The available action space and action argument space are provided between <|actionspace_start|> and <|actionspace_end|> to help guide your prediction. Please first analyze the customer's behavior patterns within the  <think> </think> section, then provide your prediction within the <answer> </answer> section, ensuring your prediction falls within the specified action and argument spaces. 

<|actionspace_start|>
Available actions are represented in JSON format. There are four primary action types with their corresponding action arguments:
1. input:
Action: Type text into an input field to search for a specific product. 
Action Argument: the input_text is the specific text entered by the customer.
{
"timestamp": "timestamp",
"action": "input",
"action_argument": "input_text",
}

2. click:
Action: Click on a UI interface button or clickable element on the Amazon website.
Action Argument: The clickable_name is one of the UI interface buttons or clickable elements including "review", "search", "product_option", "other", "nav_bar", "quantity", "page_related", "suggested_term", "cart_side_bar", "cart_page_select", and "filter". Select one of these buttons or clickable elements as action argument.
{
"timestamp": "timestamp",
"action": "click",
"action_argument": "clickable_name",
}

3. click_product:
Action: Click on product links or product images.
Action Argument: the Amazon Standard Identification Number (i.e., product_asin) of the clicked product.
{
"timestamp": "timestamp",
"action": "click_product",
"action_argument": "product_asin",
}

4. purchase:
Action: indicate intent to purchase by clicking on any purchase-related button. This includes clicking "Add to Cart", "Buy Now", "Set Subscription", or "Checkout" buttons for specific products. 
Action Argument: the Amazon Standard Identification Number (i.e., product_asin) of the product being purchased.
{
"timestamp": "timestamp",
"action": "purchase",
"action_argument": "product_asin",
}

{"bullet_list": "Translucent bottom shell design: The overall layout of the Air75 V2 wireless keyboard is similar to that of the Air75, featuring a high-quality aluminum frame. However, we have adopted a new translucent design on the bottom case of the keyboard, which makes the internal structure of the Air75v2 clearly visible and fully utilizes the overall aesthetics of the keyboard. At the same time, we've added two height stands to the bottom of the keyboard to make it even more comfortable to use. Supports multi-device connectivity: Air75 V2 wireless mechanical keyboard is compatible with Mac/Windows/Linux/Android/iOS,and supports Bluetooth 5.1 connectivity, 2.4g connectivity and wired connectivity modes, which allows you to connect up to 4 computer devices at the same time and switch between these computers to use them, which can satisfy a wide range of entertainment office needs Cool RGB Backlit Effect: The backlight of Air75 V2 has more than 21 different color effects, which can be easily changed using key combination. Through console, you can even limitlessly customize lighting effects(the keycaps are not backlit).We also added two RGB light bars on each side of the Air75 V2's aluminum frame. The left bar shows caps lock and connection mode, while the right bar shows battery level and system mode, so you can see the status of your keyboard more visually. More fun to use: Air75 V2 gaming keyboard with QMK/VIA. We believe with the full realization of our hardwares' potential under the new firmware, its open source code, the endless key remapping, light customization and other creative possibilities VIA offers our users, the fun has truly started(Wrist rest to be purchased separately) Long endurance: The battery capacity is 4000mAh, it can be used continuously for 35~57 hours(Experimental test results of keyboard backlight fully turned on), easily meet the work demand of a week.Turn off the keyboard light and it can be used for up to 220 hours (experimental test results). PBT keycaps: The keycaps are made of PBT material, providing you with a more comfortable touch, while the characters on the keycaps will not lose their color when used for a long time."}],
