Chat modes: Fast, Think, and Beyond
Pick Fast for quick answers, Think for deeper single-shot reasoning, Beyond for multi-step deliverables.
The three modes
| Mode | Use when |
|---|---|
| Fast | Everyday Q&A and short drafts |
| Think | Harder single responses that need more reasoning |
| Beyond | Multi-step plan / draft / verify work (guide) |
Select the mode in the chat composer before you send.
Plan access
- Free: Fast only. Think / Beyond / web research need Plus+ or an active Plus trial.
- Essential (grandfathered paid): Fast + Think. Beyond and web research are Plus+ features.
- Plus and above: Fast, Think, Beyond, and web research (subject to ADP and usage windows).
Starting a Plus trial from Think, Beyond, or web search keeps that mode once the trial is live.
Providers are not fixed to one brand name
Which model sits behind Fast or Think depends on plan, Advanced Data Protection, and current product defaults. Examples of live routing (mid-2026):
- Paid, ADP off: default can be xAI Grok (zero-retention path) with Anthropic backup.
- ADP on: EU Mistral path for maximum residency posture.
- Free / Essential: economy routing via OpenRouter-class paths.
Do not treat docs that say “Think = Claude Opus only” as current. For vendor diligence, use the Trust Center.
Long conversations
Very long threads may compact older context. That is a product reliability feature, not a separate “Opus-only” mode.
