How GPT-4.1 Mini and Grok 3 differ
What the numbers mean in practice when choosing between GPT-4.1 Mini and Grok 3.
-
GPT-4.1 Mini is 87% cheaper on input tokens ($0.4 vs $3 per million), which adds up quickly in document-heavy workloads.
-
GPT-4.1 Mini is 89% cheaper on output tokens ($1.6 vs $15 per million) - the bigger factor for tools that generate long documents.
-
GPT-4.1 Mini's 1.05M tokens context window is roughly 8.0x larger than Grok 3's 131.1K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
GPT-4.1 Mini has been superseded by GPT-5 Mini - for new builds, consider the newer model first.
