Every paid plan can use every model, so this is a question of fit rather than access. The full current list is on the models page, which updates as new engines are added.
Start with the job, not the name
Models are specialised. An image model that renders product photography convincingly is not necessarily the one that handles stylized illustration well, and video models differ more from each other than image models do. The tool you pick already narrows this: each tool is wired to the models that suit its job.
The trade-off that actually matters
Speed and cost move together, and both move against fidelity. Heavier models take longer and consume more credits per generation, which is why the same credit balance covers thousands of images but a much smaller number of videos. When you're still iterating on a prompt, a faster model is the cheaper way to find the composition. Switch to the heavier one for the final run.
Test on the real input
Model comparisons on someone else's sample images tell you very little about how one will handle your product, your lighting or your face. Run the same prompt and the same source photo through two models and compare those. It costs a few credits and settles the question properly.
New models
New engines are added regularly, and access isn't held back for higher plans. If a model appears on the models page, your plan can use it.
