Choose Inception Mercury if
Developers building latency-sensitive agents, voice bots or coding tools who want a fast, cheap text model behind an OpenAI-compatible API.

Look elsewhere if: Teams that need multimodal models, open weights or the widest ecosystem of hosted tools (Gemini, DeepSeek, Claude).
Choose SKI if
Mac developers who already run Claude Code, Codex or Cursor and want to manage several agents by voice.
- Uses the agent subscriptions you already have instead of reselling models
- Free plan includes the full harness with two concurrent sessions
- Projects, code and chats stay on your Mac
Look elsewhere if: Developers who want a single AI editor with built-in models and no extra layer (Cursor).
