## Axes to compare
| Axis | What to check |
| --- | --- |
| Context length | The real usable limit on your plan, not the headline number |
| File handling | Which formats, how many at once, and whether they persist between chats |
| Web access | Whether it browses live, and whether it cites what it read |
| Code execution | Whether code runs in a sandbox and what that sandbox can reach |
| Memory | Whether it remembers across sessions, and how to inspect and clear that |
| Integrations | Connectors to the tools your team actually uses |
| Data retention | Whether your inputs train the model, and the opt-out path |
| Admin controls | SSO, audit logs, per-seat policy — the reason procurement says no |

## Evaluating honestly
- [ ] Test with YOUR documents, not a demo prompt — Every assistant looks excellent on a clean example
- [ ] Write the twenty questions first, then run them on each — Otherwise you grade on vibes and pick the one you tried last
- [ ] Include questions whose honest answer is "I do not know" — How a tool handles absence matters more than how it handles ease
- [ ] Re-test after a month — These products change under you between evaluations

## FAQs
**How should I actually compare assistants?**
Write your twenty real questions first, then run all of them through each candidate. Grading afterwards on impressions reliably picks whichever one you tried most recently.

**Does my data train the model?**
It depends on the product and the plan, and it changes. Check the current terms for the exact tier you are buying and confirm the opt-out path before rolling it out to a team.
