| Tagline | Run any open-source AI model with an API call. | OpenAI's browser agent. Clicks and types on websites for you. | Chinese open-weight powerhouse. Crazy cheap, genuinely smart. | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. |

| Pricing | Pay per second of compute | Included with ChatGPT Pro $200/mo | Free web + ultra-cheap API (~$0.14/M input tokens) | Free (limited) + $10/mo Pro + $19/mo Business |
| Best for | Developers using open-source models (Flux, SDXL, Whisper, etc). | Power users willing to pay $200/mo for a browser bot. | Developers + cost-conscious builders. Anyone fine with self-hosting. | Teams with GitHub already. Devs who don't want to change IDEs. |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | B-tier. Still early. Manus is more flexible for less money. | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. |
