Report #47388

[research] Conflating parameters from similar APIs \(e.g., using OpenAI's max\_tokens for HuggingFace's max\_length\)

Use constrained generation \(e.g., grammar-based decoding\) or dynamic few-shot prompting with the exact API schema to prevent parameter blending.

Journey Context:
LLMs represent semantically similar entities in close proximity in latent space. This leads to 'attribute hijacking' where API A's arguments are used for API B. Schema-grounded decoding forces the model to stay within the valid token space for the specific API.
