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.

Talk to your coding agents and hear them talk back
Talk to your agents and hear spoken replies in real time, so you can ask for a change, hear the result and answer the follow-up without returning to the keyboard.
SKI keeps project, branch and chat context across every project, and hands each job to the right agent when you ask where things stand.
Each chat gets its own branch and worktree so parallel agents never collide; watch live diffs and open a pull request by voice.
Run Claude Code, Codex, Antigravity, OpenCode and others simultaneously, each on its own task, with a notification the moment one needs you.

Offers an enormous context window and deep Google ecosystem integration, but feels less specialized for pure reasoning tasks.
#2Delivers superior long-form coding artifacts and nuanced writing, but lacks DeepSeek's specialized open-weight reasoning models.

Features real-time X social data integration, but is less cost-effective for dedicated developer coding workflows.
SpecialistReal-time AI answer engine and research workspace combining live web citations with frontier reasoning models.

Free / Open-sourceProvides comparable open-weight foundation models and multilingual performance, but requires self-hosting or third-party inference setup.
