# Chat 6.5 vs 上下求索

The clearest difference is update cadence: Chat 6.5 at every 2 days against 上下求索's every 2 months. Chat 6.5 also leads on iOS requirement (15.6 vs 17.0). 上下求索's advantage is monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Chat 6.5 sells 4 in-app purchases, starting at $4.99 per 7 days and 上下求索 sells 5 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Chat 6.5 ships an update every 2 days, 上下求索 every 2 months. The most recent releases landed on October 24, 2026 and October 16, 2026 respectively.
