When to shortlist it
Compare Gemini 3.8 Flash when the input includes media as well as text. The documented model returns text; separate audio or image generation capabilities should not be inferred from the input formats.
What to compare before choosing
Use the stated input and output limits separately and check the consumption tier. The paid standard token rates have a dated increase on 1 January 2027, so a budget extending beyond December needs the later rates.
The documented input limit is 1,048,576 tokens and output limit is 65,536. The standard paid rates shown here expire after 31 December 2026.
