Deep dive

The capability footprint differs most on reasoning mode: o1 (12-17), structured outputs: GPT-4o-mini Search Preview, and code execution: o1 (12-17). Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, GPT-4o-mini Search Preview lists $0.15/1M input and $0.60/1M output tokens on the cheapest tracked provider, while o1 (12-17) lists $15/1M input and $60/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts GPT-4o-mini Search Preview lower by about $28.21 per million blended tokens. Availability is 2 providers versus 2, so concentration risk also matters.

Choose GPT-4o-mini Search Preview when provider fit and lower input-token cost are central to the workload. Choose o1 (12-17) when coding workflow support are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.

FAQ

Which has a larger context window, GPT-4o-mini Search Preview or o1 (12-17)?

GPT-4o-mini Search Preview supports 128k tokens, while o1 (12-17) supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, GPT-4o-mini Search Preview or o1 (12-17)?

GPT-4o-mini Search Preview is cheaper on tracked token pricing. GPT-4o-mini Search Preview costs $0.15/1M input and $0.60/1M output tokens. o1 (12-17) costs $15/1M input and $60/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is GPT-4o-mini Search Preview or o1 (12-17) open source?

GPT-4o-mini Search Preview is listed under Proprietary. o1 (12-17) is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.

Which is better for reasoning mode, GPT-4o-mini Search Preview or o1 (12-17)?

o1 (12-17) has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.

Which is better for structured outputs, GPT-4o-mini Search Preview or o1 (12-17)?

GPT-4o-mini Search Preview has the clearer documented structured outputs signal in this comparison. If structured outputs is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
