Foundation models and multimodal artificial intelligence are beginning to reshape agricultural AI by enabling systems that can integrate images, text, sensor streams, remote-sensing data, environmental records, and management information. These approaches differ from earlier narrow models because they can reuse learned representations across related tasks and support richer forms of agricultural interpretation. Their potential relevance spans crop monitoring, disease detection, advisory services, automation, forecasting, and agri-food decision support. Despite this promise, the transfer of large-scale AI systems into agriculture remains complex. Agricultural environments are biologically variable, spatially heterogeneous, seasonally dynamic, and shaped by management decisions that are often poorly captured in available datasets. As a result, questions remain about data quality, annotation adequacy, domain adaptation, validation, explainability, governance, and deployment risk. This scoping review maps emerging applications, data requirements, and deployment risks associated with foundation models and multimodal AI in agriculture and agri-food systems. It focuses on how the reviewed literature frames model architectures, data modalities, application domains, validation needs, and governance concerns. The purpose is not to estimate pooled effectiveness but to chart the evidence landscape and clarify where knowledge is advancing or remains unsettled. The review uses a scoping approach to organise literature around key concepts, model types, data inputs, agricultural tasks, implementation settings, and responsible deployment concerns. It charts relationships among remote-sensing foundation models, vision-language systems, large language models, generative AI, multimodal data fusion, benchmark datasets, and agricultural decision-support systems. It also identifies gaps in field validation, interoperability, low-resource contexts, participatory governance, and trustworthy deployment. The review contributes a structured synthesis of how foundation models and multimodal AI may extend agricultural sensing, prediction, automation, and decision support. It highlights that technical capability alone is insufficient for responsible agricultural use. Robust data infrastructures, context-aware adaptation, transparent validation, and accountable governance will be central to whether these systems support sustainable and equitable agri-food transformation.

Agricultural artificial intelligence is commonly compared through benchmark datasets and technical metrics before any field experimentation occurs. Such comparisons can help identify promising models, reveal methodological weaknesses, and organize evidence for further testing, but they cannot establish field readiness, agronomic validity, operational safety, or deployment suitability. This article proposes a conceptual framework for benchmarking agricultural AI without field experiments. The framework separates five linked assessment domains: model readiness, technical validation, data quality, contextual fit, and deployment risk and decision validity. It addresses benchmark-task clarity, metric justification, dataset representativeness, provenance, label and ground-truth uncertainty, structured validation, domain shift, robustness, calibration, uncertainty, error patterns, bias, explainability, human oversight, and monitoring requirements. Non-empirical evaluation is treated as a structured screening process based on documentation, reported evidence, cross-context reasoning, and explicit claim boundaries. The framework produces a conditional benchmark-readiness statement and a field-validation gap register rather than a deployment decision. Its principal contribution is to distinguish benchmark performance from decision validity and deployment readiness while giving researchers, developers, evaluators, and agricultural stakeholders a transparent structure for comparing evidence before field testing. The framework is conceptual, does not replace field experiments, and should be updated as new data, validation evidence, user feedback, and operational observations become available.
