Choose a model

The model picker sits above the composer. It lists every model the workspace knows about, grouped by the provider that offers it.

What is in the list

Two sources, combined:

• Tincograph — the built-in provider, always present.
• Anything you have configured in Settings, under the display name you gave it. See Bring your own model key.

Internally each entry is providerId/modelId, which is why two providers can both offer a model called llama3.1 without colliding.

The built-in models

Tincograph AI is live. The built-in provider offers three models, named for what they are good at:

• TincoAI Fast — quick answers. It is what a new chat starts with.
• TincoAI Pro — plans, reviews and long inputs.
• TincoAI Ultra — deep reasoning.

There is also an Auto mode that chooses between Fast and Pro for each request: Pro for long inputs, tool-heavy turns and plan or review asks, Fast otherwise. If you add your own provider, its models appear in the same picker.

The picker sets the model for the next chat

A chat is stamped with a model when it is created and keeps it for the whole conversation. The picker sets what the next new chat will use.

So changing the picker while a chat is open does not move that conversation to another model, even though the button at the top now reads differently. To use a different model on the same question, pick it and start a new chat.

If a chat refers to a provider you have since removed from Settings, the workspace falls back to the built-in provider rather than failing to send. An unexpected echo after editing your provider list is that fallback.

No model is locked to a plan

Every plan has the AI feature enabled, including Free. There is no “this model needs an upgrade” state, because the limit is not the model — it is the shared credit allowance every model draws from. A short reply through our servers costs one credit whichever model produced it, and a long reasoning answer costs three.

That is a deliberate choice rather than an oversight: pricing a chat by which model answered it means the price changes under you when a default changes.

What a model failure looks like

A provider error is appended to the reply in the conversation, with the status code and the first part of the provider’s own message. The commonest causes are a wrong baseUrl, a key the provider has revoked, and a model id that provider does not offer. All three are in your Settings rather than on our side.
