macaw-11b

Model description

Macaw (Multi-angle c(q)uestion answering) is a ready-to-use model capable of general question answering, showing robustness outside the domains it was trained on. It has been trained in "multi-angle" fashion, which means it can handle a flexible set of input and output "slots" (question, answer, multiple-choice options, context, and explanation) .

Macaw was built on top of T5 and comes in three sizes: macaw-11b, macaw-3b, and macaw-large, as well as an answer-focused version featured on various leaderboards macaw-answer-11b.

See https://github.com/allenai/macaw for more details.

Intended uses & limitations

How to use

python

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
tokenizer = AutoTokenizer.from_pretrained("allenai/macaw-11b")
model = AutoModelForSeq2SeqLM.from_pretrained("allenai/macaw-11b")
input_string = "$answer$ ; $mcoptions$ ; $question$ = What is the color of a cloudy sky?"
input_ids = tokenizer.encode(input_string, return_tensors="pt")
output = model.generate(input_ids, max_length=200)

>>> tokenizer.batch_decode(output, skip_special_tokens=True)
['$answer$ = gray ; $mcoptions$ = (A) blue (B) white (C) grey (D) black']
