What's New in Lekh AI

8.2

November 2, 2026

- A new Large MoE Models section in the catalogue has models with up to 35B parameters that run on your device: Gemma 4 26B, Qwen 3.6 35B, Qwen 3 30B, Qwen 3 Coder 30B, GLM 4.7 Flash, Nemotron 3 Nano 30B and Ling Mini 2.0. - They keep memory use low by loading only the parts they need from storage as they go. - Each chat starts with a clean slate, with no system prompt. Faster on-device AI - Gemma 4 runs several times faster, and thinking now works for it. - The chat stays smooth while a model is writing, including when you scroll. Better thinking - A new thinking box shows the model's reasoning as it happens, then folds away when the answer starts. - Qwen 3.5 and other reasoning models now put their thinking in the box instead of in the answer. Better formatting - Replies now show headings, bullet and numbered lists, quotes and dividers. - Long replies keep their formatting instead of turning into raw text. Fresh look - A new soft gradient behind the chat and the sidebar. - Cleaner, bolder sidebar and toolbar buttons. Additional Support - the Apple Intelligence model (iOS 26 and later) - Bonsai MLX models - the thinking on/off button - the iPhone Duo layout with its Tools tab Fixes - Fixed a crash when leaving the app while a reply was being written. - The model picker no longer disappears when you start a new chat. - Fixed a model that kept writing after it had finished its answer.

User reviews

Not Bad

Seems like a pretty good app overall and it’s great that it is now completely free. The only issues I had with it are the qwen 0.5B model seemed to be automatically installed with no obvious way to delete it in order to save storage since I wouldn’t be using that model anyway. Also under the model page there should be an option to view all installed models so you can manage/delete installed models without manually searching for them. Finally, I noticed that when starting a conversion with an LLM, it takes a while to process before starting to respond/think even with a very small model and a simple prompt compared to other local ai apps I have tried which load the models a bit faster.

Response from developer

Thanks for the detailed feedback! An installed models filter and clearer delete options would definitely make managing storage easier. Performance has also improved a lot since your review—we’re now seeing around 63 tokens/sec on iPhone Duo, up from 10. Would love to hear how the latest version runs for you!

Not free

Requires a subscription. Not free app. Free for only short trial

Response from developer

The app is now completely free, with no subscription or trial required. Thanks for giving it a try!

很好的软件

Response from developer

感谢支持!现在 App 已经完全免费,无需订阅,欢迎再试试 😊

Voice feature

First, thank you for this app. it is a good one.
Second, there are some problems:
1. Voice mode doesn’t work
2. The slider of changing voice from Kokoro TTS doesn’t work.

Awesome

Exactly what I was looking for, totally worth the money if you’re an AI enthusiast.
Really hoping for Linux support🤞

Response from developer

Thanks for the review! Really happy to hear you’re enjoying it and feel it’s worth it. As for Linux support – I’d love to get there someday. Right now I’m focused on improving the Mac version, but it’s definitely something I’ve thought about. Appreciate the support!
