Personas and tones
Personas and tones are two thin style layers that compose with the chat’s system prompt at send time. A persona sets the role the model plays; a tone tweaks how it speaks. They’re curated presets that play nicely with your own custom instructions rather than replacing them.
Personas (role)
Pick one from the composer’s + menu or from the parameters sidebar. The selected persona pre-pends a short system prompt that frames the assistant’s job.
- None — no persona. Uses only your custom instructions.
- Code Reviewer — bug hunts, security checks, blunt PR feedback.
- Writing Editor — tighten prose without flattening voice.
- Brainstorm Partner — diverge first, converge later, pushes back.
- Explain Like I’m 5 — plain language and concrete analogies.
- Translator — accurate translation that preserves tone and idiom.
When a persona is active the composer shows a small chip with the persona name above the input box. Click the chip to swap personas or clear it. Personas are per-chat — switching chats does not change them. The seed prompt itself lives on the conversation, so a reload remembers it.
Tones (style)
A tone is appended after the persona and your instructions, biasing the delivery without changing the role.
- Default — the model’s natural voice, no override.
- Direct — leads with the point; drops hedges and preamble. Replaces the old Concise tone.
- Detailed — thorough coverage with caveats and reasoning.
- Casual — plain English, conversational.
- Formal — business register.
- Encouraging — supportive framing for learners and first drafts.
- Playful — light wit and personality, humour in service of clarity.
- Skeptical — stress-tests claims, surfaces counterarguments and edge cases.
- Socratic — guides with questions instead of handing over answers; switches to direct answers when explicitly asked.
Set per chat from the parameters sidebar, or pick a default tone in Settings → General to apply to every new chat. The General tab has an expandable “What each tone does” drawer that shows the one-line summary for every tone, so the default-tone picker doubles as a reference.
How they stack
At send time the model receives, in order: your custom instructions (resolved per the precedence rules), the persona’s system prompt, and the tone modifier. The chat’s own per-chat system prompt sits at the head of all of this and always wins on the points it cares about.
