<p>Recent advances in nanotechnology bring the idea of hybrid nanomaterials to innovative applications in the solar systems, heat exchangers, etc. To identify more dynamic applications of hybrid nanomaterials, scientists have incorporated distinct thermal sources in diverse flow geometries. However, existing literature is silent about flow of viscoelastic hybrid nanofluid associated to the stretching surface flow. Therefore, the objective of current work is to propose a pioneer mathematical model for unsteady periodically oscillating flow of viscoelastic magnetized hybrid nanofluid with improved thermal features. The hybrid nanofluid contains the decomposition of graphene oxide (<i>Go</i>) and silver (<i>Ag</i>) nanoparticles in the presence of kerosene oil base fluid. The motivations for selecting suspension of graphene oxide (<i>Go</i>) and silver (<i>Ag</i>) nanoparticles with kerosene oil base material are associated to peak thermal performances and applications in heat exchangers, cooling systems, extrusion processes, solar energy, nuclear reactors, etc. The inspection of heat transfer is further examined with utilization of thermal radiation. A modified heat flux model, namely Cattaneo–Christov approach, has been followed to model the problem. The thermophysical outcomes of nanoparticles and base liquid are justified. The problem is modeled in terms of nonlinear partial differential expressions which are solved with help of homotopy analysis method (HAM). A comparative analysis for nanofluid (<i>Ag</i>/kerosene oil) and hybrid nanofluid suspension (<i>Ag-Go</i>/kerosene oil) is presented. The concluded observations reveal that heat transfer reduces due to viscoelastic fluid parameter for <InlineEquation ID="IEq1"> <InlineMediaObject> <ImageObject Color="BlackWhite" FileRef="10973_2025_14012_Article_IEq1.gif" Format="GIF" Height="19" Rendition="HTML" Resolution="72" Type="Linedraw" Width="92" /> </InlineMediaObject> <EquationSource Format="TEX">\(\left(Ag-Go\right)/\)</EquationSource> <EquationSource Format="MATHML"><math> <mrow> <mfenced close=")" open="("> <mi>A</mi> <mi>g</mi> <mo>-</mo> <mi>G</mi> <mi>o</mi> </mfenced> <mo stretchy="false">/</mo> </mrow> </math></EquationSource> </InlineEquation> kerosene oil suspension, increasing temperature profile with variations of nanoparticles volume fraction of silver and graphene oxide nanoparticles.</p>
