How Figma trained its design editing model: from SFT to RL
Figma Vice President of Engineering Josh Clemm described the training method for its design editing model, moving from supervised fine-tuning (SFT) to reinforcement learning (RL), and post-training an as-yet-unreleased editing model based on Qwen 3.8 27B. In early work, training Llama 3.3 70B on more than 250,000 samples was enough to compete with top models on editing tasks at the time. The Figma agent is now available to all users; in testing, typical tasks are about 20% faster, in expert comparisons it was better than or on par with the previous production agent in 62% of cases, user ratings were 33% higher, and undo operations were 60% fewer.
