Geeps Version 1.6

New features

• Support for OpenAI Responses API, recommended for use with reasoning models like gpt-5 and later and supporting gpt-codex models.
  • Support for reasoning_effort and verbosity parameters for OpenAI (configure defaults in API Settings > Model parameters, or set for individual chats)
• Support for Claude adaptive thinking settings (available for Sonnet and Opus 4.6+)
• Support for new automatic prompt caching for Claude models (also supported on OpenAI Responses API)
• Thinking / Resoning Summary displayed in chat when reasoning effort / adaptive thinking is enabled
• Improved web search across providers
  • OpenAI Responses API uses the native web_search tool and Chat Completions uses the newer gpt-5-search-api model for search
  • Search results are now displayed in a sheet / popover when tapping / clicking the Sources button
    • OpenRouter web search now uses web plugin instead of appending :online to model (behavior is the same)
