We are excited to share the launch of the subsequent technology of the GPT-4o mannequin sequence with GPT-4.1, 4.1-mini, and 4.1-nano to Microsoft Azure OpenAI Service.
We are excited to share the launch of the subsequent iteration of the GPT mannequin sequence with GPT-4.1, 4.1-mini, and 4.1-nano to Microsoft Azure OpenAI Service and GitHub. The GPT-4.1 fashions deliver improved capabilities and vital developments in coding, instruction following, and long-context processing that’s important for builders. We’re additionally excited to announce fine-tuning help for GPT-4.1 and 4.1-mini, permitting builders to additional customise the fashions for his or her particular enterprise wants.
What is GPT-4.1?
GPT-4.1 is the newest iteration of the GPT-4o mannequin, educated to excel at coding and instruction-following duties. This mannequin will enhance the standard of agentic workflows and speed up the productiveness of builders throughout all situations.
Key options of GPT-4.1
GPT-4.1 brings a number of notable enhancements:
- Enhanced coding and instruction following: The mannequin is optimized for higher dealing with of advanced technical and coding issues. It generates cleaner, less complicated front-end code, precisely identifies essential adjustments in present code, and constantly produces outputs that compile and run efficiently.
- Long context mannequin: GPT-4.1 helps a million token inputs, permitting it to course of and perceive in depth context in a single interplay. This functionality is especially helpful for duties requiring detailed and nuanced understanding in addition to multi-step brokers that improve context as they function.
- Improved instruction following: The mannequin excels at following detailed directions, particularly brokers containing a number of requests. It is extra intuitive and collaborative, making it simpler to work with for varied functions.
Model capabilities
In addition to the post-training enhancements and lengthy context help, GPT-4.1 retains the identical API capabilities because the GPT-4o mannequin household, together with software calling and structured outputs.
| Model | Reasoning & Accuracy | Cost & Efficiency | Context Length |
| GPT-4.1 | Highest | Higher Cost | 1M |
| GPT-4.1-mini | Balanced | Balanced | 1M |
| GPT-4.1-nano | Lower | Lowest Cost | 1M |
Coming quickly: Fine-tune GPT-4.1 to your corporation wants
Later this week, we’ll be enabling supervised fine-tuning for GPT-4.1 and 4.1-mini, empowering builders to adapt these fashions to their distinctive enterprise necessities. Fine-tuning allows you to securely customise the bottom fashions by yourself datasets, serving to align responses along with your group’s particular tone, area terminology, and job workflows. Fine-tuned fashions are managed and deployed by way of the Azure AI Foundry, supplying you with full management over versioning, safety, and scalability.
