May clinic has this to say about

“Recovery
Although some people can take months and even years to recover, most people with Guillain-Barre syndrome experience this general timeline:

After the first signs and symptoms, the condition tends to progressively worsen for about two weeks

Symptoms reach a plateau within four weeks

Recovery begins, usually lasting six to 12 months, though for some people it could take as long as three years”

Every case is different.

GBS without continuing recovery and/or worsening after 8 weeks, is by definition, CIDP.
