Language learning uses a rolling window of 200 text samples and at most 250,000 characters. New eligible text replaces the oldest recall samples. Word counts are bounded at 20,000 transitions and decay every 64 new samples. Counts can outlive individual recall samples; forget language learning clears both. Your separate chat history and documents have their own limits.
