OpenAI: GPT-4o-mini

GPT-4o mini is a previous OpenAI cheap omni snapshot, not the 2026 latest model. The still-listed GPT-4o mini card prints $0.15 input / $0.60 output per 1M tokens (cached input $0.075), aliases gpt-4o-mini and gpt-4o-mini-2024-07-18.

Compare GPT-4o if you wanted the leftover full 4o row at $2.50 / $10, GPT-5.6 Sol if you wanted the live frontier, and OpenAI if you wanted the company page.

Key Features

• Still listed, not the start-here model: Docs still describe GPT-4o mini as a cheap multimodal GPT. The models index now starts at GPT-5.6 Sol / Terra / Luna.
• Printed dollar row: $0.15 / $0.60 per 1M on the GPT-4o mini card on the public page. Confirm before you reuse leftover GPT-3.5 math.
• Website is the model card: Point at the developers model page, not a generic openai.com homepage claim that it is newest.
• No leftover MMLU crown: Do not paste 82% MMLU or "ranks higher than GPT-4" as a 2026 census.

Use Cases

• People with a GPT-4o mini bookmark who need the catalog corrected.
• People who were about to call GPT-4o mini the 2026 latest cheap OpenAI model.

Limitation: We did not re-run leftover MMLU or chat-preference crowns.

3. Confirm GPT-5.6 Sol if you wanted the live start-here model.
