Precision Intelligence for the Soil.

Qidian VP is a concept-stage architecture for combining multimodal data processing with real-world grounding to test whether farmers can receive useful, safer first-line crop guidance.

AI Architecture — Built on Google

Qidian VP is planned as a vertical AI application layered on top of Google's AI infrastructure. The MVP will test whether a focused Gemini workflow can support practical crop advisory use cases.

Gemini Vision — Crop Analysis

Gemini 2.0 Flash's native vision capability can process farm photos. Qidian VP plans to validate image-based crop issue detection across priority crops such as rice, maize, cassava, and sugarcane.

Voice — Cloud Speech-to-Text v2

The MVP will test farmer voice input, starting with Vietnamese farmer language. Broader regional dialect support is a roadmap item after initial validation.

Search Grounding — Reduced Hallucination Risk

The planned response flow will use Google Search Grounding to tie advice to selected agronomic references and reduce unsupported AI output.

Unified Gemini Response Engine

The intended MVP flow sends crop photo, symptom text or voice transcript, and selected context to Gemini. The target response is structured JSON with likely issue, confidence, suggested next step, estimated cost, and citations.

Grounded in Reality, Not Hallucinations.

Unlike a generic chatbot, Qidian VP is being designed to use Gemini's Search Grounding feature so responses can be traceable to selected agronomic references. This approach still needs to be tested with farmers and agronomists.

Data Sovereignty & Google Cloud Security

Qidian VP is intended to run on Google Cloud infrastructure. The MVP will be designed with consent, regional deployment choices, access controls, and encryption in mind before any real farmer data is collected.

Cost per Diagnosis

A working cost model will be checked against actual Google Cloud usage during MVP testing.

monitoring Detailed Validation Metrics — Planned

Metric Value Notes
Gemini API Uptime To measure Track during MVP usage in selected Google Cloud regions
Voice Recognition Accuracy To measure Start with Vietnamese farmer language and expand only after validation
Offline Model Accuracy Future test AI Edge is a later offline inference direction, not part of the first MVP claim
Image Processing Low-latency Image pre-processing + upload for 12MP smartphone photo (varies by network conditions)
Concurrent Users Tested To test Load testing after MVP endpoint implementation
Cold Start Time To measure Cold starts and latency to be measured from real Cloud Run deployment
Monthly GCP Cost Estimate To be forecast from measured MVP usage, not from completed pilot data

Crop Disease Coverage Roadmap — 240+ Target Conditions

Limitations & Known Constraints

What Qidian VP cannot do yet — and what we're working to improve.

  • warning Qidian VP does not replace professional agronomist consultation for complex multi-disease interactions.
  • warning Accuracy has not yet been validated; crop-by-crop performance must be measured during pilot testing.
  • warning Voice recognition must be tested in noisy field environments before support claims are made.
  • warning Offline capture is planned; on-device diagnosis and full treatment workflows require further validation.
  • warning Initial scope targets 4 crop categories; tropical fruits and tree crops remain future candidates.

Review the MVP Architecture

We are seeking technical feedback, cloud support, and early validation partners before building the first field-testable MVP.
