Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

New: Full capability toggles (reasoning, vision, image gen, etc.) in the Add/Edit Model screen. Fixed: Cost always showing $0.000 — pricing was stored at 1/1,000,000th the correct scale. DB migration v10 fixes existing records automatically. Session total cost and token count never updating from zero. Cached token billing now uses the discounted cache-read price instead of the full input price. OpenAI Responses API streaming wasn't capturing cached token counts. Custom provider with thinking off wasn't sending enable_thinking: false, leaving some backends silently defaulting to thinking on. Error messages truncated with no way to see the full text — tap to expand now works even without a detail field. Sidebar delete button obscured by the chat layer during the open/close transition. Removed emoji from Vision and Reasoning badges in the model picker.
