Google: Gemini Flash 1.5

Gemini 1.5 Flash is a previous Google multimodal snapshot, not the live Gemini API default. The same page still lists leftover Gemini 2.5 and Gemini 2.0 Flash.

Compare Nano Banana if you wanted Gemini image editing rather than this 2024 Flash leftover, and GPT-5.6 Sol if you wanted a current frontier chat model.

Key Features

• Previous 1.5 Flash snapshot: older copy treated 1.5 Flash as the current cheap multimodal default. Confirm the models page before you hard-code it.
• Not the 2026 Gemini lead: Live API docs lead with Gemini 3 Flash / 3 Pro / 3.1 rows.
• No invented quality/latency: Do not keep leftover "comparable to Gemini Pro at much lower cost" as a 2026 census unless you re-time a first-party page.
• No invented 2026 dollar row for 1.5: Confirm the live Gemini pricing or models page before you quote a current 1.5 Flash price.

Use Cases

• People with a Gemini 1.5 Flash bookmark who need the catalog corrected.
• People who were about to call 1.5 Flash Google's current multimodal default.

Limitation: We did not call gemini-1.5-flash or invent a 2026 per-token price.

Pricing

First-party pages on 2026-08-17.

If a leftover blog still calls 1.5 Flash Google's latest multimodal, treat the Gemini 3 models page as the correction.

Getting Started

1. Open the Gemini models page before you hard-code Gemini 1.5 Flash.
2. Confirm Gemini 3 Flash if you wanted the live Flash path.
3. Confirm Nano Banana if you wanted Gemini image editing.
4. Do not paste "latest cheap multimodal" into a 2026 deck.
