Llama 2: Open Foundation and Fine-Tuned Chat Models

The Llama 2 release introduces a family of pretrained and fine-tuned LLMs, ranging in scale from 7B to 70B parameters (7B, 13B, 70B). The pretrained models come with significant improvements over the Llama 1 models, including being trained on 40% more tokens, having a much longer context length (4k tokens 🤯), and using grouped-query attention for fast inference of the 70B model🔥!

However, the most exciting part of this release is the fine-tuned models (Llama 2-Chat), which have been optimized for dialogue applications using Reinforcement Learning from Human Feedback (RLHF). Across a wide range of helpfulness and safety benchmarks, the Llama 2-Chat models perform better than most open models and achieve comparable performance to ChatGPT according to human evaluations.

Pretrained models can be loaded with pretrained of the companion object:

val llama2 = LLAMA2Transformer.pretrained()
  .setInputCols("document")
  .setOutputCol("generation")

The default model is "llama_2_7b_chat_hf_int4", if no name is provided. For available pretrained models please see the Models Hub.

For extended examples of usage, see LLAMA2TestSpec.

Paper Abstract:

In this work, we develop and release Llama 2, a collection of pretrained and fine-tuned large language models (LLMs) ranging in scale from 7 billion to 70 billion parameters. Our fine-tuned LLMs, called Llama 2-Chat, are optimized for dialogue use cases. Our models outperform open-source chat models on most benchmarks we tested, and based on our human evaluations for helpfulness and safety, may be a suitable substitute for closed-source models. We provide a detailed description of our approach to fine-tuning and safety improvements of Llama 2-Chat in order to enable the community to build on our work and contribute to the responsible development of LLMs.

Note:

This is a very computationally expensive module especially on larger sequence. The use of an accelerator such as GPU is recommended.

Example

import spark.implicits._
import com.johnsnowlabs.nlp.base.DocumentAssembler
import com.johnsnowlabs.nlp.annotators.seq2seq.LLAMA2Transformer
import org.apache.spark.ml.Pipeline

val documentAssembler = new DocumentAssembler()
  .setInputCol("text")
  .setOutputCol("documents")

val llama2 = LLAMA2Transformer.pretrained("llama_2_7b_chat_hf_int4")
  .setInputCols(Array("documents"))
  .setMinOutputLength(10)
  .setMaxOutputLength(50)
  .setDoSample(false)
  .setTopK(50)
  .setNoRepeatNgramSize(3)
  .setOutputCol("generation")

val pipeline = new Pipeline().setStages(Array(documentAssembler, llama2))

val data = Seq(
  "My name is Leonardo."
).toDF("text")
val result = pipeline.fit(data).transform(data)

results.select("generation.result").show(truncate = false)
