I have a database table which looks as following:

id    product_id     product_name     price     date            seller
1     646            Product 1        1         2020-05-20      Seller-A
2     1554           Product 2        1.50      2020-05-23      Seller-B
3     646            Product 1        2         2020-05-22      Seller-C
4     646            Product 1        2.5       2020-05-23      Seller-A

As a result I would like to get the latest info based on the date for every product_id.

 2     1554           Product 2        1.50      2020-05-23      Seller-B    
 4     646            Product 1        2.5       2020-05-23      Seller-A

I have the following query which works fine for 1 product id:

SELECT * FROM (SELECT * FROM `table` WHERE 1 ORDER BY `date` DESC) t2 WHERE product_id = 646 GROUP BY `seller`

How should I build the query to get the results for multiple id's. At the moment it will only return the result for every seller available but no matter how many product ids are available
