DeepSeek V4 Flash Presets for SillyTavern

DeepSeek V4 Flash had a rocky launch, and I am not going to sugarcoat that. Community reports cited POV confusion, stereotypical RP output, and weak prompt adherence. The big wrinkle is that V4 ships with built-in RP instructions that actively fight custom presets, which is why it needs special handling. The good news: V4 Flash is “surprisingly good” per the community as of June 2026, and DeepSeek has committed to ongoing roleplay-specific tuning based on community feedback. The 1M context window and permanent 75% price reduction make it one of the most accessible frontier models for marathon sessions. Use V3.2 when you need reliability, V4 Flash when you need 1M context or cost.
