# Python APIs

> Which GRID SDK solves which job

Four packages, one platform. Start from the job, not the package name:

| You want to…                                                     | Use                    | Start at                                                      |
| ---------------------------------------------------------------- | ---------------------- | ------------------------------------------------------------- |
| Call hosted models (depth, detection, grasping, VLMs, VLAs)      | **grid-cortex-client** | [`CortexClient`](/python-api/grid-cortex-client/cortexclient) |
| Connect to a robot, dispatch commands, deploy + monitor programs | **grid-nexus-client**  | [`connect`](/python-api/grid-nexus-client/connect)            |
| Author the distributed programs you deploy                       | **grid-nexus-program** | [`program`](/python-api/grid-nexus-program/program)           |
| Pass poses, velocities, images between all of the above          | **grid-types**         | [`overview`](/python-api/grid-types/overview)                 |

Every page in this section is generated from the package source — signatures,
parameters, and examples are the code's own docstrings, verified fresh in CI.
