| Tagline | Chinese open-weight powerhouse. Crazy cheap, genuinely smart. | Run any open-source AI model with an API call. | Microsoft/GitHub's autocomplete. Deep VS Code + JetBrains integration. | The GitHub of AI. Models, datasets, spaces — all in one. |
| Category | chat | dev platform | coding | dev platform |
| Pricing | Free web + ultra-cheap API (~$0.14/M input tokens) | Pay per second of compute | Free (limited) + $10/mo Pro + $19/mo Business | Free + $9-$20/mo + enterprise |
| Best for | Developers + cost-conscious builders. Anyone fine with self-hosting. | Developers using open-source models (Flux, SDXL, Whisper, etc). | Teams with GitHub already. Devs who don't want to change IDEs. | Any ML/AI developer. Hobbyists exploring open models. |

| Kai's verdict | S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick. | S-tier for open-source model APIs. The default in this space. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier infrastructure. The one platform every AI dev eventually uses. |
