  • PaLM has variants like Med-PaLM for medical data and PaLM-E, a vision-language model for robotic manipulation, both showcasing superior performance in their domains. PaLM 2, a 340 billion parameter model trained on 3.6 trillion tokens, was unveiled at Google I/O in May 2023.

Dolly by Databricks

  • Dolly is a language model trained on Databricks, using approximately 15k instruction/response records by Databricks employees based on Pythia-12b.
  • Despite being not cutting-edge, Dolly-v2-12b exhibits exceptional instruction-following behavior, surprising for its foundational model.
  • The model is listed as databricks/dolly-v2-12b on Hugging Face.

Cerebras-GPT from Cerebras

  • The Cerebras-GPT family includes 111M, 256M, 590M, 1.3B, 2.7B, 6.7B, and 13B models, trained according to Chinchilla scaling laws (20 tokens per model parameter) for compute optimization.
  • These models were trained on the Andromeda AI supercomputer, utilizing 16 CS-2 wafer-scale systems, and benefited from Cerebras' weight streaming technology for simplified LLM training.
  • All models from the Cerebras-GPT family are available on Hugging Face for research purposes in exploring LLM scaling laws with open architectures and datasets.

Falcon by Technology Innovation Institute (TII), UAE

  • Falcon, developed by the Technology Innovation Institute (TII), UAE, is the first open-source large language model on the list, outperforming other open-source models like LLaMA and MPT.
  • With Apache 2.0 license, Falcon can be used for commercial purposes without royalties or restrictions, offering two models trained on 40B and 7B parameters.
  • While primarily trained in English, German, Spanish, and French, Falcon also supports Italian, Portuguese, Polish, Dutch, Romanian, Czech, and Swedish languages, making it a versatile choice for open-source AI models.

BERT by Google

  • BERT (Bidirectional Encoder Representations from Transformers) introduced by Google AI in 2018, revolutionized NLP with its bidirectional context capturing.
  • BERT pre-trains a transformer-based neural network using masked language modeling to predict masked words from the surrounding context.
  • BERT's impact led to the development of advanced models like RoBERTa, ALBERT, and ELECTRA, enhancing performance and efficiency in various NLP tasks.

XLNet by Google

  • XLNet, introduced by Google AI in 2019, addresses limitations in traditional language models by modeling all permutations of input sequences during pre-training.
  • Unlike autoregressive models, XLNet considers bidirectional context by capturing relationships between all positions in the sequence.
  • Utilizing Transformer architecture and permutation language modeling, XLNet achieves effective bidirectional context and dependency capture.
  • XLNet is typically used as a pre-trained model and can be fine-tuned for specific NLP tasks, with open-source code and pre-trained models available for further research and development.
