PositionID: LLMs can Control Lengths, Copy and Paste with Explicit Positional Awareness

The podcast on this paper is generated with Google's Illuminate.

LLMs gain human-like awareness of word positions through numbered tracking.

Adding position markers to LLM inputs enables exact length control and accurate text manipulation.

Original Problem 🔍:

LLMs struggle with length control and precise copy-paste operations due to lack of positional awareness.

The authors identify a lack of positional awareness as the root cause of LLMs' inability to effectively control text length. This stems from token-level operations and insufficient training on data with strict length limitations.

-----

Solution in this Paper 🛠️:

• PositionID Prompting: Assigns sequential IDs to words/sentences/paragraphs during generation

• PositionID Fine-Tuning: Trains models on mixed normal and PositionID modes

• PositionID CP Prompting: Enables accurate copy-paste using a three-stage tool-use mechanism

-----

Key Insights from this Paper 💡:

• Explicit positional awareness enhances LLMs' length control and copy-paste abilities

• PositionID techniques work for both closed-source and open-source models

• Mixed-mode training transfers positional awareness to normal generation mode

-----

Results 📊:

• PositionID Prompting: Best Rouge-L (23.2) and MAE scores across all levels

• PositionID Fine-Tuning: Outperforms CFT and InstructCTG in MAE metrics

• PositionID CP Prompting: 80.8% CP Success Rate, 18.4 Rouge-L, 8.4 PPL
