Overall Performance Comparison

Model	Key Strengths	Limitations / Notes	Benchmark / Ranking Takeaways
🐍 L3‑70B‑Euryale‑v2.1	High creativity, flexible RP, unique swipes, custom formats, strong prompt adherence, fast improvisation	Limited long-memory; smaller context window restricts extended multi-turn storytelling; some features like “spatial awareness” are observed by users but not officially verified	Best free, highly creative, flexible RP. Ideal for short, experimental sessions.
🐉 L3.1‑70B‑Euryale‑v2.2	Deep, lore-rich multi-turn storytelling, consistent characters, immersive world-building, historically/specialized accurate RP, emotional expression	Paid tier; larger context may slightly slow response; some context window values vary across sources	Best for long-memory, deep storytelling, immersive roleplay. Ideal for structured or high-fidelity RP sessions.
🦅L3.3‑70B‑Euryale‑v2.3	Balanced all-rounder: flexible, responsive, steady personality consistency, smooth scene progression; high context and creative reasoning	Slightly less raw creativity than v2.1 in improvisation; paid tier	Best all-rounder — balances creativity, memory, adaptability, and reliability for both short and long RP sessions.
