Kimi K3.1 and Qwen4 are reportedly in the final stages before release and may launch this week.

BlockBeats news, October 22 — Max For AI posted a disclosure that Kimi K3.1 and Qwen4 have both entered the final pre-release stage and are currently undergoing anonymous testing on Arena, with releases expected within this week.

Previously, the community spotted two anonymous models, Kibitz and Kalmia, on Arena. The account @aitrackerbot, through tokenizer testing, found that Kibitz's characteristics point to Moonshot AI's Kimi, while Kalmia is suspected to come from Alibaba's Qwen. Max For AI stated that both teams had been intensively running benchmark tests over the past few days, and that after the anonymous models went live on Arena, official releases may be imminent.

At present, the identities of the relevant models and release dates are still pending official confirmation.
