| Pricing | Pay per second of compute | Token-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens. | Included with ChatGPT Plus/Pro | Free + $49-$249/mo |
| Best for | Developers using open-source models (Flux, SDXL, Whisper, etc). | Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch. | ChatGPT subscribers experimenting with cinematic shots. | RevOps + marketing ops automating repetitive tasks. |

| Kai's verdict | S-tier for open-source model APIs. The default in this space. | If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.) | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | A-tier for ops automation. B-tier for simple copy (use Claude). |
