Direct imaging of exoplanets remains a challenge, but with new instruments we are beginning to observe long-period giants in unprecedented detail. Observed high-res spectra of these giants act as Rosetta stones for planetary history, providing insights into their chemistry and orbital characteristics. Much of this information is imprinted in their atmospheres, and to harness it, we need models that match the precision of these observations.I've developed a new high-res model based on Exo-REM --a well-established tool for simulating atmospheres, previously limited to low resolutions--by incorporating the latest high-res molecular data and updated isotopologue abundances. This new model extracts properties in detail often inaccessible with lower-res observations. I'll present the results from applying it to specific enigmatic exoplanets, demonstrating how high-res spectra can refine our understanding of atmospheres. As we move towards bridging the gap between long- and short-period period objects, these techniques will be crucial in paving the way for studying smaller and cooler worlds, furthering our understanding of the diversity of systems.
