 ## Features
 
 - **Up-to-date model list** - the catalog is loaded dynamically from the Hub API on every startup and always reflects its current state. Model capabilities (context limits, reasoning, tool use, etc.) are resolved from the models.dev catalog.
-- **OpenAI and Anthropic models** - both model families are supported, including GPT-5.x and Claude 4.x.
-- **Reasoning support** - `interleaved thinking` mode is enabled automatically for Anthropic models.
+- **All available models** - every model exposed by the Hub is supported.
+- **Reasoning support** - `interleaved thinking` mode is enabled automatically where applicable.

 ## Возможности
 
 - **Актуальный список моделей** — каталог динамически загружается из API Hub при каждом запуске и всегда отражает его текущее состояние. Возможности моделей (контекст, reasoning, tool use и т.д.) определяются из каталога models.dev.
-- **Модели OpenAI и Anthropic** — поддерживаются обе линейки, включая GPT-5.x и Claude 4.x.
-- **Поддержка reasoning** — для моделей Anthropic автоматически включается режим `interleaved thinking`.
+- **Все доступные модели** — поддерживается любая модель, предоставленная Hub.
+- **Поддержка reasoning** — режим `interleaved thinking` включается автоматически там, где это применимо.
