| Tagline | Anthropic's CLI agent. Opus-powered, operates on your repo directly. | Run any open-source AI model with an API call. | OpenAI's browser agent. Clicks and types on websites for you. | OpenAI's video model. Long clips, cinematic quality. |
| Category | coding | dev platform | agents | video |
| Pricing | Part of Claude Pro/Max/Team plans | Pay per second of compute | Included with ChatGPT Pro $200/mo | Included with ChatGPT Plus/Pro |
| Best for | Developers who want an agent, not autocomplete. Large refactors, tests, docs. | Developers using open-source models (Flux, SDXL, Whisper, etc). | Power users willing to pay $200/mo for a browser bot. | ChatGPT subscribers experimenting with cinematic shots. |

| Kai's verdict | S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement. | S-tier for open-source model APIs. The default in this space. | B-tier. Still early. Manus is more flexible for less money. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
