It scores 31.8% on BigCodeBench and 0.0 on SHADE-Arena. At $0.40/$1.60 per 1M tokens with a 1M-token context window, it is the most capable OpenAI model in the $0.40 input price range. ## At a Glance **Where GPT-4.1 mini leads** - 1M-token context window — 8× the context of GPT-4o mini (128K), at $0.40 input - $0.40/$1.60 per 1M — cost-efficient with full 1M context - 31.8% BigCodeBench — competitive general coding at the mini tier - Multimodal vision support - GPT-4.1 training lineage — improved instruction following vs GPT-4o mini **Where it lags** - 0.0 SHADE-Arena — low agentic sabotage detection (indicates safe baseline but limited agentic reasoning) - Below GPT-4.1 (32.8% BigCodeBench) — expected for the mini tier - No reasoning mode - June 2024 knowledge cutoff **Best for:** High-volume pipelines requiring 1M context at $0.40 input — document analysis, whole-repository code tasks, and large-batch inference that would be too expensive at GPT-4.1 pricing ($2/$8). ## What GPT-4.1 mini Is GPT-4.1 mini is the mid-tier model in the GPT-4.1 family, sitting between GPT-4.1 ($2/$8) and GPT-4.1 nano (not yet shown) on the capability/cost spectrum. Its headline feature is the 1M-token context window at $0.40 input — making it the most cost-efficient way to access 1M context on the OpenAI API. Released alongside GPT-4.1 on April 14, 2025, GPT-4.1 mini replaced GPT-4o mini as the recommended cost-tier model for most workloads, offering the same price range ($0.40 vs $0.15 input) with dramatically more context (1M vs 128K tokens) and better overall performance from the GPT-4.1 training lineage. For budget-constrained workloads that don't require 1M context, Gemini 2.5 Flash at $0.15/$0.60 provides better benchmark coverage. For workloads that specifically benefit from 1M context at minimal cost, GPT-4.1 mini is the strongest proprietary option. ## Specifications | Field | Value | |---|---| | Organization | OpenAI | | Parameters | Undisclosed | | Context window | 1,000,000 tokens | | License | Proprietary (API only) | | Release date | April 14, 2025 | | Knowledge cutoff | June 2024 | | Modality | Text + Vision (multimodal) | ## Pricing | | Input (per 1M tokens) | Output (per 1M tokens) | |---|---|---| | OpenAI API | $0.40 | $1.60 | Prompt caching provides a 75% discount on cached input.

What is GPT-4.1 mini?

GPT-4.1 mini is OpenAI's April 2025 mid-tier model with a 1M-token context window at $0.40/$1.60 per 1M tokens. It scores 31.8% BigCodeBench and supports vision input.

What is GPT-4.1 mini's context window?

GPT-4.1 mini supports a 1,000,000-token context window — the same as the full GPT-4.1 model.

How much does GPT-4.1 mini cost?

$0.40 per 1M input tokens and $1.60 per 1M output tokens, with a 75% cached input discount.

Should I use GPT-4.1 mini or GPT-4o mini?

For tasks requiring long context (>128K tokens), GPT-4.1 mini is the clear choice — 1M vs 128K context at 2.7× higher input cost. For tasks that fit within 128K tokens and are highly cost-sensitive, GPT-4o mini or Gemini 2.5 Flash are better value.
