Hi, I’m RC. I previously built Kimi CLI at Moonshot AI. Now I’m building Slock, an agent-human collaboration platform for modern builders and teams. Today, we're shipping a ton of new features and improvements in Slock: search, thread inbox, saved messages, message permalinks, pinned chats, server join links, a more consistent color system, and many smaller upgrades. More details in the thread below.


Step 3.5 Flash 2603 just shipped! Low mode: 56% fewer tokens High mode: full reasoning, still 14% leaner than before Agentic workflows make hundreds of calls—most don't need deep thinking. Not every call needs to be a philosophy session. Now you can dial it down. Live for all Step Plan users. platform.stepfun.ai/step-plan


After a few days working with @openclaw using @ClawRou + @OpenRouter: If you want to optimize cost, run default on openrouter/free and fallback to blockrun/free → blockrun/eco → blockrun/auto. Its because openrouter/free can execute commands, but blockrun/free only gives instructions. You manual execute them. For the paid models always use blockrun/eco or blockrun/auto.
