“Be My Eyes” is a independent early partner of OpenAI, having access to GPT-4 computer vision for many months before it was available by API.

The excessive input context that Assistants can use with multiple internal calls and context loading outside your control is mitigated by a lower cost, if the new model can still perform the task.
