Daily puzzle: leave today's month, date, and one model cell open. Pick the model — the one releasing that day if you know it. Dates use Asia/Shanghai. Not Rank, not an official model calendar.
Drag pieces (phone too). Tap a selected piece to rotate. Hint places one piece from a known solution. Combos with no solution are marked in the picker.
FAQ
What is the AItier daily puzzle?
A personal toy: 10 pieces, three windows. Leave the month, the date, and one model cell open. Rank is still aitier.app.
Which models are on the board?
CLA Claude · GPT OpenAI · GEM Gemini · GRO Grok · DS DeepSeek · QW Qwen · KM Kimi. Short names only, not SKUs, not weekdays, not a ranking.
What timezone?
Asia/Shanghai, marked on the page. The model cell is whichever you pick — not the weekday.
Is this an official model calendar?
No. AItier is a personal list product. This page is not a lab calendar and not a leaderboard.
