Which one would each critic pick
| Critic | NVIDIA NeMo Agent Toolkit | Qwen-Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 8.0 | Qwen-Agent — Pick Qwen-Agent if you are building on Qwen models and want the framework the vendor uses itself; pick a neutral framework if you expect to change model families next year. |
| El Crítico | 6.5 | 6.8 | Qwen-Agent — The demos track each new model release from the same team, so the tested path is one family's behaviour, and the code interpreter executes what the model writes. |
| El Profesor | 7.5 | 7.0 | NVIDIA NeMo Agent Toolkit — It supplies an evaluation harness for other people's agents and publishes no evaluation of its own, which is a defensible asymmetry and worth noticing. |
| La Inversora | 8.0 | 8.5 | Qwen-Agent — 17,063 stars and a trillion-dollar owner. This is not a product, it is customer acquisition for a model business, and it has been running since September 2023. |
| La Jefa | 8.0 | 7.0 | NVIDIA NeMo Agent Toolkit — No licence cost for sixty engineers, it runs unattended in our pipelines, and the tracing path is a third-party service my data protection officer will ask about. |
| El Hacker | 7.0 | 8.3 | Qwen-Agent — Apache-2.0, one pip install with the extras I choose, MCP support in the framework, and any OpenAI-compatible endpoint means a self-hosted model of the same family runs the whole thing. |
