By training on your own examples, the model learns your domain patterns directly improving accuracy, stability, and reducing prompt complexity. Supervised fine-tuning allows you to train on large datasets without prompt-length limits. This gives you tighter control over model behavior, reduces the need for manual prompt engineering, and can lead to lower inference cost and latency.\ \ Upcoming Advanced post-training options including: * **Speculative Decoding** optimization (private beta [\[sign up\]](https://docs.google.com/forms/d/e/1FAIpQLSfp8KM7LAJtWfykJrpdcasYAO_9A4rEfhaEf2q0IuklWa3SDA/viewform)) * **Reinforcement Fine-tuning** (limited professional service [\[request access\]](https://nebius.com/reinforcement-fine-tuning-research-program)) You can currently run **long-context supervised fine-tuning** on full model weights or **LoRA adapters**. If you're ready to fine-tune or want to explore the workflows involved, start here: Step-by-step guide to preparing data, launching a job, and evaluating results. Supported base models for training and inference. Create and manage datasets for training and validation. Serve LoRA-adapted models serverlessly with per-token billing. ***
