Introducing Agronomist

The model family at the centre of DeepLeaf's food-systems infrastructure. It sees the crop, reasons over weather, soil and satellite, calls specialist tools, computes instead of guessing, and speaks in local languages and dialects.

This looks like early blight, likely from the wet spell. Tomorrow morning is a good spray window.

The Agronomist app, with an example conversation.

Vision diagnosis

Crop first, then cause, then problem. Agronomist asks a follow-up question when a photo is not enough, and states its likelihood in words. Fungus, bacteria, virus, insect, nematode, nutrient or weather stress.

This looks like early blight, most likely from the wet spell. Tomorrow morning is a good window to spray.

Extended reasoning

Agronomist thinks before answering. The reasoning stays folded so the reply stays short, and opens for anyone who wants to check it.

You

my tomato leaves have brown spots

Brown rings with a yellow halo, lower canopy first. Field is day 41, 18 mm of rain in three days.

Consistent with early blight. Need registered products before naming any.

Likely early blight (Alternaria solani). Remove the lowest leaves today and spray tomorrow 06:00 to 10:00 with a product on the national register.

Where farmers already are

The same conversation continues from WhatsApp to the app to a voice call. Same farmer, same fields, same memory.

Managed WhatsApp: DeepLeaf runs the number. Farmers message it like a neighbour.
API relay: Your bot, your number. Point your OpenAI client at Agronomist.
White-label: On your domain, under your brand, with your price list.
Morning briefing: At 06:00: health, problem areas, spray window, next action.

Real-time voice and video

Barge-in: the farmer can interrupt, and Agronomist stops and listens.
Backchannel: short acknowledgements while the farmer is still talking.
Switch fields by voice: “now the olive grove”.
Video: point the camera at the crop during the call.

Tool use over Earth observation

Health map, satellite zones, 16-day hourly weather, rain so far, growing degree days and soil, for the field in question.

Agronomic compute

Tank fills, spray hours and crop stage are computed from the label, the sprayer and the forecast. They are never recalled from memory.
