Share the frameworks. Never share private Memory. Version everything so someone else — or future you — can continue cleanly.
| Capability | Plus | Heavy |
|---|---|---|
| Custom Instructions | Full | Full + higher effective depth |
| Custom Agents | Available (verify slots) | Available + stronger parallel collaboration |
| Projects / Workspaces | Full | Full + higher limits |
| Memory | Full | Full + priority |
| Multi-agent reasoning | Limited / sequential | Native parallel (Grok Heavy) |
| Usage / Rate limits | Significantly higher | Maximum + priority queue |
| Compute priority | Priority at peak | Highest |
| Best for | Daily structured work, creation, research | Extremely complex multi-step synthesis, large frameworks, team-like agent work |
Share safely
- Export Custom Instructions and Project notes as plain Markdown.
- Version them (v1.0, v1.1…).
- Share only the frameworks, never private Memory contents.
- Use the “someone else can continue” principle: leave placeholders and decision records.
On this complex problem, spawn parallel agents: one for evidence, one for options, one for risks, one for synthesis. Each reports with honesty labels. Then merge under human-decision priority.
