AA7075 and AA7072 nanoparticles suspended in sodium alginate (SA) base fluid make up the hybrid nanofluid (HNF), which was selected due to its improved heat transfer properties and superior thermal conductivity. The model’s practical applicability is enhanced by melting heat, nonlinear thermal radiation, boundary slip, and Newtonian heating effects, which are considered for surface heat flow. A dataset spanning three cases and seven scenarios of SBHNF is generated by solving the simplified governing equations using the built-in MATLAB bvp4c numerical methods. The dataset comprises three divisions: 80% allocated for training, 10% for validation, and 10% for testing. The proposed system is employed for the analysis of stream and thermal transmission, with conclusions validated by several approaches, including error histograms, regression plots, time series analysis, mean square error (MSE) of the loss function, autocorrelation, and cross-correlation. Findings from the AI-based LMA validate the suggested method for solving the SBHNF accurately. Joule heating, variable thermal conductivity, and other external sources elevate fluid temperature, whereas radiation heating markedly amplifies surface heat energy by accumulating, hence improving heat transfer. The opposing forces produced by magnetic fields, Darcy’s law, and electro-osmosis reduce fluid velocity, which is effective for wellbore stability and hydraulic efficiency. The MSE and coefficient of determination (R²) are used to assess the correctness and robustness of the suggested computational framework. The trained network indicated outstanding predictive accuracy with R2=0.999 for all scenarios. The error histogram for the proposed model is 10−6 to 10−7. The seven scenarios of SBHNF fall within the range of 10−8 to 10−13 for the attained high MSE (loss function) convergence levels.
