Changelog
May 4, 2026 · v3.4.0
- featureNew and updated model choices
The model catalogue has been refreshed with newer GPT, Claude, Grok, DeepSeek, OpenRouter, Cohere, Google, Mistral, Fireworks, and Together options. The aim is simple: more current models, fewer dead ends, and better choices in one place.
- improvementAuto Mode is better at picking the right model
Auto Mode now uses fresh scorecard data to choose models more confidently for writing, coding, research, reasoning, and everyday chat. You can still pick a model yourself, but leaving it on Auto should now feel more reliable.
- fixFewer broken or unavailable model choices
We removed duplicate model entries and turned off models that were failing live checks, so the picker should show fewer options that look available but fail when you try to use them.
- improvementMore reliable model routing
Several providers now route through the most dependable connection available. That means fewer failed replies and a smoother experience when a model is best served through a partner route.
- improvementA faster, more stable foundation
We updated the AI engine and app runtime behind JustSimpleChat. This is mostly invisible, but it helps keep the app faster, more compatible, and easier to improve.

The OpenAI model list has been refreshed, including newer GPT models and better handling for reasoning settings. This should make the latest OpenAI options easier to find and use.

A styling issue from the deployment pipeline was corrected, restoring the intended look and feel across the app.
April 26, 2026 · v3.3.0

- improvementBetter continuity during longer chats
Routing improvements help the app keep context when conversations become more detailed, especially when a task needs several replies to complete properly.
