Experienced issues while using Kimi K2.6 in both reasoning and non-reasoning versions. Query often ends up as "Upstream provider is unavailable, please try again later.". Nearly every query is affected in my case. Issue also doesn't seem to depend on web search setting. First time I've encountered this issue around 3-4 days ago. Last typical response from Kimi K2.6 in my case was 2026-05-16, but while writing this report I somehow managed to get two proper ones: this with thinking block formatting issue and this. Example affected assistant threads: here and here. Similar issue was reported here but tagged as appearance bug.
I've never had similar issues while interacting with these models on other platforms. Also Kimi K2.5 seems to not be affected at all. Please review the case and try to resolve degraded output issue.
