Auto

The right model for every message, picked for you

Auto works out what kind of task each message is and how demanding it is, then picks a model ranked for that work, with a reasoning level to match. Quick questions go to a fast model, and demanding work to a stronger one that reasons more.

How Auto works

A quick step before each reply picks the model for it.

Send your message

Auto reads your latest message along with the recent conversation.

It judges the task

One of 23 kinds of task, from writing and code to math, research, money and law, and whether it’s routine, standard or demanding.

It picks a model

Each kind of task has its own ranking of models. Money, legal and security questions always get a thorough one.

Under the hood

How Auto classifies and routes a message

Every message gets its own decision. Auto reads it and scores two things: what kind of task it is, and how demanding. It routes only once it’s at least 70% sure, choosing the lightest difficulty that clears that bar. Each task and difficulty has its own ranking of models and reasoning levels, and your message goes to the top of that list.

23 kinds of task

Conversation, writing, translation, summaries, research, math, science, finance, legal, planning, code, data and more.

3 levels of difficulty

Routine, standard and demanding. Harder work goes to a stronger model with more reasoning, and quick questions stay fast.

When it isn’t sure

If Auto can’t classify a message confidently, or can’t see all of it yet, like an attachment or a project’s files, it takes a dependable everyday route instead of guessing.

“Should I put an extra $400 a month toward my mortgage or into an index fund?” is Finance, standard. Auto routes it to Claude Fable 5.2 at low reasoning.

Plan 3 days in Lisbon in May for two — food and viewpoints, mid budget.

Here’s a relaxed three-day plan built around food and viewpoints, at a mid-range budget for two.

Day 1 — Alfama and Baixa
  • Morning: tram 28 up to Miradouro de Santa Luzia, then wander Alfama’s lanes.
  • Lunch: grilled sardines at a tasca near the Sé, about €30 for two.
  • Sunset: Miradouro da Senhora do Monte, the widest view over the city.
Day 2 — Belém and LX Factory
  • Pastéis de Belém before the queue builds, then the Jerónimos cloister.
  • Dinner at LX Factory, then a drink on a riverside terrace.

Ask without opening the model picker
Choose Auto once and just ask. Before each reply, Auto judges the kind of task and how demanding it is, then picks a model for it.
Each message gets its own choice. Your next message is judged on its own, so a follow-up can go to a different model.
