Ubisoft uses AI21 Labs to automate NPC dialogue variation generation for game scriptwriters
Ubisoft scriptwriters faced extremely tedious manual work generating large numbers of NPC dialogue variations (bark trees), and lacked the fine-tuning data needed to automate the process internally — creating it by hand was wholly impractical.
How it works
Common implementation structure
How this type of workflow is generally built, generalized across documented cases — not tied to any one vendor's stack. Click any stage to read what happens there. Specific products that implement these stages appear in “Tools commonly seen” below.
Stage 1 · Writer needs bark tree variations
Scriptwriters need to produce multiple NPC dialogue variations for each shared motivation.

Outcome
Ubisoft achieved rapid scaling of NPC content production, unlocking an unlimited fountain of training data while optimizing costs with a 30:1 input-to-output token ratio under AI21's output-only pricing.
What failed first
Other LLM providers introduced legal compliance friction and charged for both input and output tokens, making large-scale data augmentation experiments prohibitively expensive.
