A question about "context"

[1185307269]

What does the 'context' parameter in this command represent?
If I change --context "1" to --context "2"，the generated files differ in the number at the beginning of the sequence.

python3 sample.py --model ${model} --t 0.8 --p 0.9 --max-length 1024 --num-samples 2 --context "1"
