Which one would each critic pick
| Critic | Julep | Spring AI Alibaba | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.5 | 7.3 | Spring AI Alibaba — Pick Spring AI Alibaba if your services are Java and Spring; pick Koog if the team writes Kotlin and wants the agent compiled into a mobile build. |
| El Crítico | 5.8 | 6.3 | Spring AI Alibaba — The reference model integration in the documentation is the vendor's own hosted service, so provider neutrality is a property to verify rather than assume in a regulated deployment. |
| El Profesor | 6.8 | 7.0 | Spring AI Alibaba — Context engineering is exposed as named hooks rather than folklore: compaction, context editing, tool retry, call limits and dynamic tool selection are configuration, not prompt craft. |
| La Inversora | 6.0 | 6.3 | Spring AI Alibaba — Alibaba is buying the Java enterprise market's attention with an open framework, and the return arrives as cloud model consumption rather than a licence. |
| La Jefa | 6.3 | 6.3 | no preference |
| El Hacker | 7.3 | 6.8 | Julep — Apache-2.0 Python I can read end to end, MCP tools arriving over a protocol instead of plugins, and a CLI that deploys flows, but no local model path. |
