AI teammates that run on the subscriptions you already pay for.
Sign in with ChatGPT, Claude, Grok, or Cursor, or use your own API key, and run local models through Ollama. Switch models mid-conversation without losing context.
One Chief of Staff agent coordinates specialist agents — outreach, launch writer, signups, engineer — and hands work between them, returning results to your chat.
Persistent agents remember how you like work done and how you write in each app, from Gmail to WhatsApp, and draft replies in your voice. Nothing sends until you approve.
Each agent works in its own tab of the Turnstone Browser, opening sites, reading pages, and filling forms while you watch. Scheduled jobs run automatically and report back.
High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
