GPT-4.1 reveals stable outcomes throughout these evaluations. In factual accuracy exams, 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 customary refusal exams, and 0.86 on tougher prompts.
Nonetheless, within the StrongReject jailbreak check—a tutorial benchmark for security underneath adversarial circumstances—GPT-4.1 scored 0.23, behind fashions like GPT-4o-mini and o3.
That mentioned, it scored a robust 0.96 on human-sourced jailbreak prompts, indicating extra strong real-world security underneath typical use.
In instruction adherence, GPT-4.1 follows OpenAI’s outlined hierarchy (system over developer, developer over consumer messages) with a rating of 0.71 for resolving system vs. consumer message conflicts. It additionally performs properly in safeguarding protected phrases and avoiding answer giveaways in tutoring eventualities.
Contextualizing GPT-4.1 in opposition to 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 data base, and decreased 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 refined.
Regardless of these good points, GPT-4.5 drew criticism for its excessive value — 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. Trade figures famous that whereas GPT-4.5 was stronger normally dialog and content material technology, it underperformed in developer-specific functions.
In contrast, GPT-4.1 is meant as a sooner, extra centered different. Whereas it lacks GPT-4.5’s breadth of data and in depth emotional modeling, it’s higher tuned for sensible coding help and adheres extra reliably to consumer directions.
On OpenAI’s API, GPT-4.1 is at the moment 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 stability between pace and intelligence at a decrease price, GPT-4.1 mini is on the market 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 presents stronger software program engineering benchmarks and extra exact instruction following, which can be important for enterprise deployment eventualities requiring reliability over price. In the end, 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.
