Over the Mid-Autumn holiday, an unsigned model — "Space Bunny" — suddenly topped both the OpenRouter and OpenCode daily usage charts, with discussion trending in lockstep. The community busied itself guessing its owner: Grok? A Chinese lab? QbitAI's editor took another route: forget attribution, just test it.
Hands-on: fast and capable
Via OpenRouter into DeepSeek Harness, it built an interactive Three.js Temple of Heaven with a self-cycling day/night (3.5 minutes per day) and weather toggles; a "better-fitting" Mac alarm app in one round; and even a desktop app rendering the model's own chain-of-thought as subtitles — window-dragging fixed in a single follow-up. Across a dozen-plus coding tasks, almost nothing survived more than one round of feedback; multimodal video understanding produced structured analysis too.
A divided community
First-hand impressions split: fans call it a "tool maniac" that检索-plans-calls in one breath; critics note occasional rough edges — solid worker, not an Astra-class showstopper. Speed is the consensus strength.
Anonymous chart-storming has become a launch ritual: ship quietly, collect real feedback, reveal later. Whoever Space Bunny turns out to be, one thing is clear — leaderboards where users vote with tokens beat press events.
Keep calm
Daily-usage No.1 reflects real API spend and developer stickiness — but anonymous models lack version commitments, SLAs and compliance. Production selection should still prioritize stable supply, private deployment and security audit.
To try new models like this one on day one, besides OpenRouter, developers in China can connect via TuneRouter — an OpenAI-compatible API relay offering multi-model aggregation, per-token usage and quota management, working out of the box with mainstream clients, no overseas payment or network hurdles.
