Kling V2.5 Turbo T2V

[Core Function] Kling V2.5 Turbo T2V is a fast, cost-effective text-to-video model. [Strengths] It offers very fast generation speeds and great value while maintaining 1080p resolution for 5s/10s clips. [Best For] Highly recommended for: rapid prototyping, batch social media creation, and cost-sensitive pipelines. [Limitations] Do NOT use this model for the absolute highest cinematic fidelity or native audio synchronization. [Routing] Choose this model when the user emphasizes ‘fast’, ‘quick’, or ‘cost-effective’ generation.
