Gemini 2.0 Flash Thinking

Gemini 2.0 Flash Thinking is a previous Google reasoning snapshot on the 2.0 Flash family, not a 2026 o1-mini alternative. Rechecked 2026-08-18: dedicated Thinking docs URLs 404. The first-party Gemini 2.0 Flash card now says that family is deprecated and shut down June 1, 2026. Live Flash reasoning controls sit on Gemini 3.7 Flash. Drop leftover visible CoT crown / faster than o1 / cheaper than o1 / current thinking default.

Compare Gemini 3.7 Flash if you wanted live thinking-token controls, Gemini 2.0 Flash if you wanted the leftover 2.0 chat twin, and o1-mini if you wanted the leftover cheap OpenAI reasoning snapshot.

Key Features

• Leftover 2.0 thinking path: Dedicated Thinking URLs 404. Treat this slug as the leftover 2.0 reasoning twin, not a live product page.
• Same shutdown family as 2.0 Flash: The 2.0 Flash card marks the family deprecated and shut down June 1, 2026.
• Not the 2026 reasoning default: Live Flash thinking-token controls sit on Gemini 3.7 Flash.
• No leftover o1 comparison: Do not paste "approaches o1-mini" or "more economical than o1" as a 2026 census.

Use Cases

• People with a Gemini 2.0 Flash Thinking bookmark who need the catalog corrected.
• People comparing leftover 2.0 thinking vs live Gemini 3.7 Flash thinking-token controls.
• People who were about to call it a current o1-mini alternative.

Limitation: We did not re-open a 404 Thinking card or invent a 2026 per-token price for a shut-down SKU.
