What's the characters-per-Wh of an LLM compared to traditional OCR?

A lot worse. But, higher quality OCR will reduce the amount of human post-processing needed, and, in turn will allow us to reduce the number of humans. Since humans are relatively expensive in energy use, this can be expected to save a lot of energy.

Are they? I'm seeing figures around 80 watts at rest, and 150 when exercising. The brain itself only uses about 20 watts [1]. That's 1/35 of a single H100's power consumption (700 watts - which doesn't even take into account the energy required to cool the data center, the humans who build and maintain it, ...).

The PUE of humans for that 80 watts is terrible, though. Ridiculous multiples of additional energy needed to convert solar power to a form of a energy that they can use, and even the manufacturing lifecycle and transport of humans to the datacenter is energy inefficient.

What's the value-add here? The schemas?

Basically there is no model schema combination. IF you go ahead and prompt a open source model with the schema it doesn't produce the results in the expected format. The main contribution is how to make these model conform to your specific needs and in a structured format.

Wait, but we're doing that already, and it works well (Qwen 2.5 VL)? If need be, you can always resort to structured generation to enforce schema conformity?
