Big shoutout to the team behind the Model—absolutely awesome work! 🚀 Taking their inspiration and giving APEX a try to build something the world hasn't seen yet. If you are building next-gen AI-driven mobile apps, this is the frontier. 📱⚡️ Stay tuned. We're rewriting the rules. @callstackio @apex__ai #ReactNative #AI

@apex__ai heard it works well with Stim

@apex__ai Curious how it fares on Stim's benchmark. So far model choice doesn't make a big difference since the goal of the CLI is to make it as simple as possible for the agent.

@apex__ai The useful test for an open model isn't whether it beats a frontier model at everything, but whether it can own a well-defined slice of the stack at a cost that makes shipping easier.

@apex__ai The model looks useful. Does it write middleware too, or only the components?
