Shape Their Persona

Each employee has an identity you set on their Profile tab, and a brain the whole workspace shares from one place. This article covers both: who the employee is, and how the AI behind every employee is configured.

TL;DR

Go to Workspace, select an employee, open the Profile tab to set their name, role, background, language, and tone of voice. The AI model, thinking depth, and actions-per-turn limit are workspace-wide settings, not per-employee: change them at Settings > AI Config. Profile fields save automatically when you click away.

What Is on the Profile Tab

The Profile tab is divided into four sections:

Identity

Controls who the employee is.

Field What It Does
Avatar The employee's profile picture. Click it to upload a photo (JPEG, PNG, GIF, or WebP, up to 5 MB)
Name Display name used in the sidebar, chat, and across the platform
Role Job title shown on the employee's profile (e.g., "Content Writer," "Marketing Strategist")
Team Which team the employee belongs to. Changing it moves them the same way dragging them on the org chart does

Reports To and Mentor are shown as read-only info: Reports To is derived from the employee's team leader (or you, if there is no leader), and Mentor is the same guide for every employee.

Persona

Controls who the employee is, not how they talk.

Field What It Does
Background & Personality A text field where you describe the employee's background, what they care about, and how they think about their work

This is the who, not the how, tone and language live in the Voice section below and should not repeat here. Each employee starts with a template-seeded default, and the employee can refine its own persona over time through the same field.

Voice

Controls how the employee talks.

Field What It Does
Language The employee's default language. Leave it empty and the employee mirrors whichever language you write in
Tone of Voice Free text describing tone, e.g. "Warm and direct. Plain English, no jargon."

Contact

Where people can reach this employee directly.

Field What It Does
Email A live mailbox address (<employee>@<yourworkspace>.mail.sista.ai). Email it and the employee replies from the same address
Slack Shows the connected Slack handle, or a button to connect Slack for this employee
Phone Not available yet

AI Model, Thinking Depth, and Actions per Turn

These are not per-employee settings today. They are set once for the whole workspace at Settings > AI Config (/technical/ai-models), and every employee uses the same brain.

Field What It Does
Model Which AI model every employee uses by default. Grouped by tier: Fast, Standard, Advanced, and Frontier
Credits Saver A toggle that automatically routes simple, conversational turns to a faster model and keeps the model above for real work
Thinking Depth How hard the model reasons before responding. Only active for models that support extended reasoning
Creativity The model's temperature (0 to 2, default 0.7). Lower is steadier and more predictable, higher is more varied
Actions per Turn How many actions (tool calls, reads, searches) an employee can take in a single response

The model dropdown shows models from OpenAI, Anthropic, and other providers, grouped by tier. Bigger models are smarter but slower and cost more credits per turn.

AI Model Tiers

Tier Best For
Fast Quick responses, lowest credit cost
Standard Good balance of speed and capability
Advanced Best quality, highest credit cost
Frontier Top-of-line brains, the very best quality

Exact credit cost per model changes as providers change their pricing, so the number shown next to each model in the picker is always the current one, not a fixed table.

Thinking Depth

For models that support extended thinking:

Level What It Does
Auto (Recommended) Adjusts dynamically: quick for simple messages, deeper for complex ones
Off No reasoning. Fastest responses, lowest cost
Minimal / Light / Medium / Deep Increasing levels of reasoning depth and cost

The dropdown is disabled when the selected model does not support reasoning.

Frequently Asked Questions

Q: Does changing the personality affect the quality of work? A: No. Persona changes the style of communication (background, personality) but not the quality or accuracy of the output.

Q: Can I set a different AI model for each employee? A: Not today. The AI model, thinking depth, and actions per turn are set once at Settings > AI Config and apply to every employee in the workspace.

Q: What happens if the AI provider goes down? A: The gateway automatically retries with a fallback model from a different provider. You are billed at the fallback model's rate, not the original.

Q: Can I change the employee's name? A: Yes. Edit the Name field in the Identity section of the Profile tab. The change takes effect immediately.

Q: What does "Actions per Turn" mean? A: It limits how many actions (tool calls, reads, searches) an employee can perform in a single response. Higher values allow longer, multi-step work.

Q: Can I upload a custom photo for my employee? A: Yes. Click the avatar on the Profile tab and upload a JPEG, PNG, GIF, or WebP file up to 5 MB.
