When to shortlist it
Compare Gemini API as a platform when your workload needs a documented choice of text, multimodal or specialized models. Select one model and consumption option before estimating cost.
What to compare before choosing
Free-tier, paid-tier and service-tier terms differ. Check the exact model’s availability and limits; do not infer new-account access from the existence of a legacy model in the catalogue.
Model availability differs by family. The documentation restricts Gemini 2.5 access to prior users and directs new projects to newer models.
