Damn, this rocks! I used to check the Uber, Freenow and Lyft apps one by one to get the cheapest one. With the dynamic pricing you never know these days.
But guess what... I just checked on Bliq and realized there's yet another player in town. With Bolt, the forth ride-hailing app is available here now and even cheaper than all of the others for my ride!
I could imagine this being super useful...

Yesterday OpenAI released the new ChatGPT API, which is better than the best previous OpenAI models and 90% cheaper to use!
I had fun integrating it to chat with any PDF - free and without sign-in!
Let me know what you think š
