LLMLingua utilizes a compact, well-trained language model (e.g., GPT2-small, LLaMA-7B) to identify and remove non-essential tokens in prompts. This approach enables efficient inference with large language models (LLMs), achieving up to 20x compression with minimal performance loss.

LongLLMLingua mitigates the 'lost in the middle' issue in LLMs, enhancing long-context information processing. It reduces costs and boosts efficiency with prompt compression, improving RAG performance by up to 21.4% using only 1/4 of the tokens.

LLMLingua-2, a small-size yet powerful prompt compression method trained via data distillation from GPT-4 for token classification with a BERT-level encoder, excels in task-agnostic compression. It surpasses LLMLingua in handling out-of-domain data, offering 3x-6x faster performance.

- Ever encountered the token limit when asking ChatGPT to summarize lengthy texts?
- Frustrated with ChatGPT forgetting previous instructions after extensive fine-tuning?
- Experienced high costs using GPT3.5/4 API for experiments despite excellent results?
While Large Language Models like ChatGPT and GPT-4 excel in generalization and reasoning, they often face challenges like prompt length limits and prompt-based pricing schemes.
Now you can use LLMLingua, LongLLMLingua, and LLMLingua-2!
These tools offer an efficient solution to compress prompts by up to 20x, enhancing the utility of LLMs.
- 💰 Cost Savings: Reduces both prompt and generation lengths with minimal overhead.
- 📝 Extended Context Support: Enhances support for longer contexts, mitigates the "lost in the middle" issue, and boosts overall performance.
- ⚖️ Robustness: No additional training needed for LLMs.
- 🕵️ Knowledge Retention: Maintains original prompt information like ICL and reasoning.
- 📜 KV-Cache Compression: Accelerates inference process.
- 🪃 Comprehensive Recovery: GPT-4 can recover all key information from compressed prompts.
PS: This demo is based on the alt-gpt project. Special thanks to @Livshitz for their valuable contribution.

}To get started with LLMLingua, simply install it using pip:
pip install llmlinguaWith LLMLingua, you can easily compress your prompts. Here’s how you can do it:
from llmlingua import PromptCompressor
llm_lingua = PromptCompressor()
compressed_prompt = llm_lingua.compress_prompt(prompt, instruction="", question="", target_token=200)
# > {'compressed_prompt': 'Question: Sam bought a dozen boxes, each with 30 highlighter pens inside, for $10 each box. He reanged five of boxes into packages of sixlters each and sold them $3 per. He sold the rest theters separately at the of three pens $2. How much did make in total, dollars?\nLets think step step\nSam bought 1 boxes x00 oflters.\nHe bought 12 * 300ters in total\nSam then took 5 boxes 6ters0ters.\nHe sold these boxes for 5 *5\nAfterelling these boxes there were 3030 highlighters remaining.\nThese form 330 / 3 = 110 groups of three pens.\nHe sold each of these groups for $2 each, so made 110 * 2 = $220 from them.\nIn total, then, he earned $220 + $15 = $235.\nSince his original cost was $120, he earned $235 - $120 = $115 in profit.\nThe answer is 115',

## Or use the phi-2 model,
llm_lingua = PromptCompressor("microsoft/phi-2")
## Or use the quantation model, like TheBloke/Llama-2-7b-Chat-GPTQ, only need <8GB GPU memory.
## Before that, you need to pip install optimum auto-gptq
llm_lingua = PromptCompressor("TheBloke/Llama-2-7b-Chat-GPTQ", model_config={"revision": "main"})To try LongLLMLingua in your scenarios, you can use
from llmlingua import PromptCompressor
llm_lingua = PromptCompressor()
compressed_prompt = llm_lingua.compress_prompt(
prompt_list,
question=question,
rate=0.55,
# Set the special parameter for LongLLMLingua
condition_in_question="after_condition",
reorder_context="sort",
dynamic_context_compression_ratio=0.3, # or 0.4
condition_compare=True,
context_budget="+100",
rank_method="longllmlingua",
)To try LLMLingua-2 in your scenarios, you can use
from llmlingua import PromptCompressor
llm_lingua = PromptCompressor(
model_name="microsoft/llmlingua-2-xlm-roberta-large-meetingbank",
use_llmlingua2=True, # Whether to use llmlingua-2
)
compressed_prompt = llm_lingua.compress_prompt(prompt, rate=0.33, force_tokens = ['\n', '?'])
## Or use LLMLingua-2-small model
llm_lingua = PromptCompressor(
model_name="microsoft/llmlingua-2-bert-base-multilingual-cased-meetingbank",
use_llmlingua2=True, # Whether to use llmlingua-2
)Split text into sections, decide on whether to compress and its rate. Use <llmlingua></llmlingua> tags for context segmentation, with optional rate and compress parameters.
