A chip design claims 19 times the AI work per watt of an H100, and it draws as little as 122 milliwatts. Power, not speed, is the limit for AI on small devices, and that is a business.

A model shipped into rural Cote d'Ivoire called half the healthy samples infected. Four hours of local labelling fixed it, and that fix is something you can sell.
Business Ideas/Agritech/Ethiopia · Tanzania
Two African labs built crop disease models that run on a phone with no signal. The business is not the model, it is the shop counter where a dealer guesses today.

Ordinary weather records forecast hourly sunlight in Ibadan with a yearly error of 0.19, using free public code. The buyer is the operator deciding tonight about the generator.
An offline crop disease model scored 97.3 percent on cactus-fig photos taken at university test plots. No farmer has ever used it, and the paper describes that figure two different ways.
From Africa/Climate & energy tech/Nigeria · South Africa
A Random Forest model turned ordinary weather records into hourly sunlight forecasts for one site in Ibadan, Nigeria. Its yearly error on total sunlight was 0.19.
From Africa/Agritech/Tanzania
A Tanzanian team trained a Vision Transformer on 100,000 bean leaf images, adding tiny nudges made to fool it. Accuracy rose from 97.4 percent to 99.4 percent.
From Africa/Biotech & health tech/Côte d'Ivoire · USA · Canada
A team in Cote d'Ivoire relabelled a day of microscope images, retrained the model overnight, and tested it the next morning. Its catch rate rose from 75.5 to 98.1 percent.
From Africa/Agritech/Ethiopia
A team at Mekelle University in Ethiopia photographed 3,587 cactus-fig pads and trained three models on them. The best scored 97.3 percent and fits in 9.3 MB.
