Right now, we’re excited to announce two main enhancements to mannequin fine-tuning in Azure AI Foundry—Reinforcement Nice-Tuning (RFT) with o4-mini, coming quickly, and Supervised Nice-Tuning (SFT) for the 4.1-nano mannequin, out there now.
Right now, we’re excited to announce three main enhancements to mannequin fine-tuning in Azure AI Foundry—Reinforcement Nice-Tuning (RFT) with o4-mini (coming quickly), Supervised Nice-Tuning (SFT) for the GPT-4.1-nano and Llama 4 Scout mannequin (out there now). These updates replicate our continued dedication to empowering organizations with instruments to construct extremely custom-made, domain-adapted AI techniques for real-world affect.
With these new fashions, we’re unblocking two main avenues of LLM customization: GPT-4.1-nano is a robust small mannequin, splendid for distillation, whereas o4-mini is the primary reasoning mannequin you’ll be able to fine-tune, and Llama 4 Scout is a best-in-class open supply mannequin.
Reinforcement Nice-Tuning with o4-mini
Reinforcement Nice-Tuning introduces a brand new stage of management for aligning mannequin conduct with complicated enterprise logic. By rewarding correct reasoning and penalizing undesirable outputs, RFT improves mannequin decision-making in dynamic or high-stakes environments.
Coming quickly for the o4-mini mannequin, RFT unlocks new prospects to be used circumstances requiring adaptive reasoning, contextual consciousness, and domain-specific logic—all whereas sustaining quick inference efficiency.
Actual world affect: DraftWise
DraftWise, a authorized tech startup, used reinforcement fine-tuning (RFT) in Azure AI Foundry Fashions to reinforce the efficiency of reasoning fashions tailor-made for contract technology and evaluation. Confronted with the problem of delivering extremely contextual, legally sound strategies to legal professionals, DraftWise fine-tuned Azure OpenAI fashions utilizing proprietary authorized knowledge to enhance response accuracy and adapt to nuanced person prompts. This led to a 30% enchancment in search outcome high quality, enabling legal professionals to draft contracts sooner and give attention to high-value advisory work.
Reinforcement fine-tuning on reasoning fashions is a possible sport changer for us. It’s serving to our fashions perceive the nuance of authorized language and reply extra intelligently to complicated drafting directions, which guarantees to make our product considerably extra helpful to legal professionals in actual time.

When do you have to use Reinforcement Nice-Tuning?
Reinforcement Nice-Tuning is greatest fitted to use circumstances the place adaptability, iterative studying, and domain-specific conduct are important. You need to take into account RFT in case your situation includes:
- Customized Rule Implementation: RFT thrives in environments the place resolution logic is extremely particular to your group and can’t be simply captured by means of static prompts or conventional coaching knowledge. It permits fashions to be taught versatile, evolving guidelines that replicate real-world complexity.
- Area-Particular Operational Requirements: Splendid for situations the place inner procedures diverge from business norms—and the place success is dependent upon adhering to these bespoke requirements. RFT can successfully encode procedural variations, comparable to prolonged timelines or modified compliance thresholds, into the mannequin’s conduct.
- Excessive Resolution-Making Complexity: RFT excels in domains with layered logic and variable-rich resolution timber. When outcomes rely upon navigating quite a few subcases or dynamically weighing a number of inputs, RFT helps fashions generalize throughout complexity and ship extra constant, correct choices.
Instance: Wealth advisory at Contoso Wellness
To showcase the potential of RFT, take into account Contoso Wellness, a fictitious wealth advisory agency. Utilizing RFT, the o4-mini mannequin realized to adapt to distinctive enterprise guidelines, comparable to figuring out optimum consumer interactions based mostly on nuanced patterns just like the ratio of a consumer’s web price to out there funds. This enabled Contoso to streamline their onboarding processes and make extra knowledgeable choices sooner.
Supervised Nice-Tuning now out there for GPT-4.1-nano
We’re additionally bringing Supervised Nice-Tuning (SFT) to the GPT-4.1-nano mannequin—a small however highly effective basis mannequin optimized for high-throughput, cost-sensitive workloads. With SFT, you’ll be able to instill your mannequin with company-specific tone, terminology, workflows, and structured outputs—all tailor-made to your area. This mannequin will likely be out there for fine-tuning within the coming days.
Why Nice-tune GPT-4.1-nano?
- Precision at Scale: Tailor the mannequin’s responses whereas sustaining pace and effectivity.
- Enterprise-Grade Output: Guarantee alignment with enterprise processes and tone-of-voice.
- Light-weight and Deployable: Good for situations the place latency and price matter—comparable to customer support bots, on-device processing, or high-volume doc parsing.
In comparison with bigger fashions, 4.1-nano delivers sooner inference and decrease compute prices, making it nicely fitted to large-scale workloads like:
- Buyer assist automation, the place fashions should deal with hundreds of tickets per hour with constant tone and accuracy.
- Inside information assistants that observe firm fashion and protocol in summarizing documentation or responding to FAQs.
As a small, quick, however extremely succesful mannequin, GPT-4.1-nano makes a terrific candidate for distillation as nicely. You should utilize fashions like GPT-4.1 or o4 to generate coaching knowledge—or seize manufacturing site visitors with saved completions—and train 4.1-nano to be simply as sensible!
Llama 4 Nice-Tuning now out there
We’re additionally excited to announce assist for fine-tuning Meta’s Llama 4 Scout—a leading edge,17 billion energetic parameter mannequin which provides an business main context window of 10M tokens whereas becoming on a single H100 GPU for inferencing. It’s a best-in-class mannequin, and extra highly effective than all earlier technology llama fashions.
Llama 4 fine-tuning is out there in our managed compute providing, permitting you to fine-tune and inference utilizing your personal GPU quota. Accessible in each Azure AI Foundry and as Azure Machine Studying elements, you will have entry to extra hyperparameters for deeper customization in comparison with our serverless expertise.
