Which one would each critic pick
| Critic | Anda | Upsonic | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.5 | 6.0 | Upsonic — Pick Upsonic if you want an autonomous agent running in four lines with a directory as its boundary; pick Pydantic AI when you want the typed loop and a larger library behind it. |
| El Crítico | 5.5 | 5.8 | Upsonic — The stated safety model is a workspace path plus blocked dangerous commands, and a command blocklist is the weakest control in this category, not a sandbox. |
| El Profesor | 7.3 | 6.3 | Anda — Servers expose capability groups that an agent expands only when it needs the schemas, which is a genuine answer to tool-description bloat in the context window. |
| La Inversora | 5.0 | 5.5 | Upsonic — A company name, a documentation site and no price anywhere, which means the product decision has not been made yet and the framework is holding the position. |
| La Jefa | 4.8 | 4.8 | no preference |
| El Hacker | 6.8 | 6.5 | Anda — Apache-2.0, a cargo install, signed outbound calls and per-agent isolated state, though the row records no local inference, so the weights are still remote. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
