TinyML in agriculture: findings and reporting gaps
A review of 28 studies reports that agricultural TinyML deployments largely rely on ESP32, STM32, and ATMega microcontrollers. Some plant-disease detection systems report 90–97% accuracy and latency as low as 7.6 ms, but memory and energy metrics are often missing.

The review says models typically run inference on-device in the field while training remains in the cloud. Quantization appears in over half of deployments, whereas structured pruning and neural architecture search are rare.
The authors say sparse reporting of flash, RAM, operation counts, and energy per inference hinders reproducibility and fair comparison. They propose an architecture spanning sensing, inference, edge processing, and cloud training.
Why it matters
The review shows why on-device inference may suit small farms with intermittent connectivity, and identifies reporting gaps that make deployments hard to evaluate.
GUIDES
Something to try
For a hypothetical farm-sensor project, plan to report accuracy alongside RAM, flash, latency, and energy per inference.

Prism ML’s ternary-weight Ternary-Bonsai-2-2B reduces the language model to about 0.52 GB, versus roughly 3.8 GB at FP16. It retains a 262K-token context window and image input, with the vision component loaded separately. Weights take values of −1, 0, or +1; additional scale metadata raises the actual storage cost. Image input requires an optional 0.36 GB Q8_0 mmproj file.
Crusoe confirmed it sold an unfinished data center project in southeastern Wyoming to Google. Google said it plans to invest $17 billion to develop the campus; the purchase price was not disclosed. Crusoe announced the project last year with Tallgrass, with plans to eventually scale it to 10 gigawatts. Google is taking over development; the report says it had raised concerns about costs and the construction timeline under Crusoe’s management.
OpenGVLab released the 0.9-billion-parameter InternVL2-1B vision-language model under the MIT license. It reportedly scores 754 on OCRBench, above PaliGemma-3B at 614 and Mini-InternVL-2B at 654. The model combines an InternViT-300M vision encoder with Qwen2-0.5B-Instruct and has an 8K context window. It targets tasks including OCR, document and chart analysis, and video question answering.
