Best memory in uncensored AI chat models

Why memory matters for uncensored chat

Long-form roleplay and storytelling require the model to remember character details, plot points, and user preferences across dozens of exchanges. A model that forgets your character's name after 12 turns breaks immersion. A model that confuses two characters mid-scene is unusable for serious creative work.

Most "best NSFW AI chat" lists ignore memory entirely. Our benchmark measures it directly.

How we test memory

1. A fixed persona and scenario are loaded into the system prompt.
2. The user introduces three named facts across the first four turns.
3. At turns 4, 8, 16, and 24, the model is asked to recall each fact.
4. We test both plot facts (events that happened) and preference facts (stated likes and dislikes).
5. We also inject a false memory at turn 12 and test whether the model resists or adopts it.

Each model runs three samples. Scores reflect consistency across runs, not best-case performance.

What the scores mean

• 15/15: Perfect recall at 24 turns with no false-memory adoption.
• 10–14: Minor omissions or one missed fact at 24 turns.
• 5–9: Significant memory gaps beyond 8 turns.
• 0–4: Amnesia-level performance; unreliable for sessions longer than a few exchanges.

Models with strong memory characteristics

Based on architecture alone, larger context windows and higher parameter counts correlate with better recall. Models with 128K+ context and 70B+ parameters (like Hermes 3 405B and Euryale 70B) have the hardware capacity for strong memory performance. Smaller models can still perform well if they are fine-tuned for long-context adherence. Live scores will confirm or refute these architectural expectations.
