“First impressions of @opencode newly released "Cat Jam" model I’ve only done some initial runtime testing so far, but one thing immediately blew me away: Nearly 200 tokens/sec. 🤯 Honestly, I’m more impressed by its speed than its intelligence at this point. Is this speed normal, or am I missing something? 👀 Would love to hear from others testing it!”

“For me this is the stealth modelling that's working better. No hangs. Ultra fast. Very opinionated and arrogant. Like it.”
