Default Model Settings

Configure per-conversation defaults — temperature, token limits, and system prompts — for your workspace. These defaults apply within whichever workspace AI source you've chosen (managed inference or BYOK); they don't change the source itself. See workspace-ai-source for the workspace-level managed-vs-BYOK decision.

Default parameters#

When a new conversation starts, these defaults apply:

Parameter	Description	Range	Default
Model	Which LLM to use	Provider-specific	Largest available
Temperature	Response creativity	0.0–1.0	0.7
Max tokens	Maximum response length	1–provider max	4,096
Top P	Nucleus sampling threshold	0.0–1.0	1.0

System prompt#

The system prompt sets Sidekick's baseline behavior. The default prompt includes:

Governance awareness (propose before acting)
Workspace context (available connections and tools)
Safety guidelines (escalation triggers)

Customizing the system prompt#

You can append custom instructions:

Always respond in a professional tone.
When drafting emails, use the signature: "Best regards, [Team Name]"
Prefer bullet points over paragraphs for summaries.

Custom instructions are appended to — not replacing — the platform system prompt. This ensures governance behavior is always present.

Per-conversation overrides#

You can override defaults in any conversation by using Sidekick commands:

/temperature 0.3
/model gpt-4o-mini

Overrides persist for the duration of the conversation and don't affect workspace defaults.

Info

Lower temperature (0.0–0.3) produces more consistent, factual responses. Higher temperature (0.7–1.0) produces more creative, varied output.
