> first mention i've heard of abacus.ai and IDE. what do you think stands out about them?

Their reasoning agent is better than anything else I've used, tbh. The inability to use it in a CLI environment is why I stopped using it. They have a router that they hook into that "intelligently" chooses models for you in a normal "chat" setting. The power comes with their DeepThink (or whatever) mode that has a VM hooked up to it, as well as many, many well designed agents and internal prompts that handle all sorts of interesting things, from planning to front-end dev, to reasoning about requirements and requirements fulfillment.

ah yeah i have heard about their router. i wonder if GPT5 doing a router hurt it a bit.
