OpenAI has additionally launched a Security Evaluations Hub web site to provide customers entry to key efficiency metrics throughout fashions.
GPT-4.1 exhibits stable outcomes throughout these evaluations. In factual accuracy assessments, it scored 0.40 on the SimpleQA benchmark and 0.63 on PersonQA, outperforming a number of predecessors.
It additionally scored 0.99 on OpenAI’s “not unsafe” measure in commonplace refusal assessments, and 0.86 on tougher prompts.
Nonetheless, within the StrongReject jailbreak take a look at—a tutorial benchmark for security underneath adversarial situations—GPT-4.1 scored 0.23, behind fashions like GPT-4o-mini and o3.
That stated, it scored a robust 0.96 on human-sourced jailbreak prompts, indicating extra sturdy real-world security underneath typical use.
In instruction adherence, GPT-4.1 follows OpenAI’s outlined hierarchy (system over developer, developer over person messages) with a rating of 0.71 for resolving system vs. person message conflicts. It additionally performs properly in safeguarding protected phrases and avoiding answer giveaways in tutoring situations.
Contextualizing GPT-4.1 towards predecessors
The discharge of GPT-4.1 comes after scrutiny round GPT-4.5, which debuted in February 2025 as a analysis preview. That mannequin emphasised higher unsupervised studying, a richer information base, and lowered hallucinations—falling from 61.8% in GPT-4o to 37.1%. It additionally showcased enhancements in emotional nuance and long-form writing, however many customers discovered the enhancements delicate.
Regardless of these positive factors, GPT-4.5 drew criticism for its excessive worth — as much as $180 per million output tokens by way of API —and for underwhelming efficiency in math and coding benchmarks relative to OpenAI’s o-series fashions. Business figures famous that whereas GPT-4.5 was stronger on the whole dialog and content material technology, it underperformed in developer-specific purposes.
In contrast, GPT-4.1 is meant as a quicker, extra targeted different. Whereas it lacks GPT-4.5’s breadth of information and in depth emotional modeling, it’s higher tuned for sensible coding help and adheres extra reliably to person directions.
On OpenAI’s API, GPT-4.1 is at present priced at $2.00 per million enter tokens, $0.50 per million cached enter tokens, and $8.00 per million output tokens.
For these looking for a steadiness between pace and intelligence at a decrease price, GPT-4.1 mini is out there at $0.40 per million enter tokens, $0.10 per million cached enter tokens, and $1.60 per million output tokens.
Google’s Flash-Lite and Flash fashions can be found beginning at $0.075–$0.10 per million enter tokens and $0.30–$0.40 per million output tokens, lower than a tenth the price of GPT-4.1’s base charges.
However whereas GPT-4.1 is priced greater, it gives stronger software program engineering benchmarks and extra exact instruction following, which can be essential for enterprise deployment situations requiring reliability over price. Finally, OpenAI’s GPT-4.1 delivers a premium expertise for precision and improvement efficiency, whereas Google’s Gemini fashions enchantment to cost-conscious enterprises needing versatile mannequin tiers and multimodal capabilities.
