The default order is Kimi-K2.6, MiniMax-M2.7, Qwen3-Coder, Qwen3.6-Plus, Qwen3-Max, and Qwen3-Thinking. diff --git a/README.md b/README.md index 294091e..94a0725 100644 --- a/README.md +++ b/README.md @@ -13,7 +13,7 @@ The proxy now supports two backend modes: ## Current Version -The current desktop line is `v1.4.3`. +The current desktop line is `v1.4.4`.
