Grok has memory now
Like ChatGPT, xAI's Grok now has memory. It can remember all your conversations and you can ask it to retrieve any information that you have talked about earlier. Now, when you ask any question, you get more personalized suggestions.
Also, from a few days ago Grok 3 API is also available to use and you can check the pricing here. It's still in beta, though. There's also a simple API cost calculator where you can estimate the cost of using different models including xAI's through APIs. It's minimal, clean, and completely free to use.
