Models

You choose the work. Sezio chooses the model.

Sezio runs on its own models, built to understand your situation and to tell what really matters to you. For more complex work it calls on the world's leading AI models, such as GPT, Claude, Gemini, Grok, Kimi, GLM, MiniMax, DeepSeek and Qwen, and picks the one that suits the job automatically.

Sezio decides for every request. You never pick a model.

01

What Sezio's own models do.

  • Read the situation

    They understand what an email, a meeting or a ticket means for your day.

  • Decide what matters

    They weigh every item against your goals, your promises and your deadlines.

  • Work fast, all day

    Sorting, extracting and prioritizing run continuously, so your brief is ready when you are.

  • Pick the model for the job

    They decide when a request needs a leading model, and which one.

  • Know your language and your way of working

    Optimized for the languages we serve, Turkish included, and guided by what Sezio remembers about you.

  • Stay behind every request

    Whichever model does the heavy lifting, Sezio's own models prepare the request and shape what comes back.

02

The best AI model depends on the job.

One model writes better, another reasons better, another is faster or reads longer documents. Models also change every month. Sezio keeps track so you don't have to, and sends each request to the model best suited to that job.

03

The models Sezio works with.

Sezio's own models come first. The rest are the world's leading model families, called on when a job needs them.

04

You never pick a model.

There is no model menu in Sezio. You say what you want done, and Sezio decides how. You choose the work, and the model follows.

05

You can talk to it, too.

Sezio understands speech and can read its answers aloud, so a note dictated between two meetings ends up where it belongs.

Voice note · 3:12 PM
Remind me about the proposal after the Thornbury meeting on Tuesday.
Note saved · ThornburyReminder on Tuesday at 3:00 PM
Spoken reply

I'll remind you about the proposal after Tuesday's Thornbury meeting.

A note said between meetings lands where it belongs.
