Ehsan's Verdict

Teams switching from Replika to AI21 Labs Jamba report measurable improvements, but the reverse migration path also exists for good reasons. In AI chat & assistants, multi-turn reasoning is where the biggest gap appears. context retention remains a contested area where both tools have legitimate claims. My advice: trial both for 2 weeks against your actual research assistance workflow. The winner will be obvious within days.
