Text Degeneration: A Production Failure Mode That Most Benchmarks Do Not Track
The article discusses a phenomenon known as Text Degeneration in autoregressive language models, which leads to inefficiencies in inference cost and throughput. This issue arises when a small number of requests enter a generation loop, causing repeated token outputs without reaching an end-of-sequence signal. The authors argue that this structural problem is rooted in the training objectives of these models and cannot be resolved through simple tuning adjustments.
- ▪Text Degeneration is a self-reinforcing failure mode observed in autoregressive language models.
- ▪A small percentage of requests can consume a disproportionate amount of processing time due to repeated token generation.
- ▪The issue is structural and stems from the training objectives of language models, making it difficult to mitigate through configuration changes.
