Released on November 9, 2026, Seedream 5.5 is ByteDance Seed's next-generation image creation model engineered for professional visual production workflows. Supporting 1K, 1.5K, and 2K resolutions (2K default, no 4K), it allows 1 to 10 reference images to maintain character, product, and style consistency. The model delivers three major technical breakthroughs: up to 100 rounds of pixel-level, non-destructive multi-turn editing without color drift; native RGBA transparent background generation in PNG format; and high-accuracy text rendering across 15+ languages including Chinese and English.

Seedream 5.5 Spicy is based on ByteDance Seed's Seedream 5.5 image generation model, in its Spicy mode (uncensored improved version) with relaxed content restrictions compared to the standard version. As a channel-customized variant that preserves the original base model's powerful generative engine, users must comply with applicable local laws and regulations. It offers 1K, 1.5K, and 2K resolutions (with 2K as default), supports 1–10 reference images, and enables up to 100 rounds of pixel-level multi-turn editing without color drift or detail loss. It natively generates RGBA transparent backgrounds and delivers accurate text rendering across 15+ languages.

Seedance 2.5 Spicy is an uncensored video generation model built on ByteDance's Seedance 2.5 architecture. Engineered for cinematic dynamics, it transforms image and text prompts into ultra-fluid video sequences featuring complex camera movements, precise physical interactions, and multi-subject consistency. Operating without safety filters as an uncensored model, it supports native resolutions up to 4K and multi-image references, empowering creators to render high-impact action sequences and unrestricted visual content.

Seedance 2.5 Economy is engineered as a high-value supplementary pipeline for large-scale cost reduction, it maintains exceptional motion stability and native audio synchronization whenever connected. The economy-tier model does not support the use of real-life photographs as reference images; please switch to the official version if you wish to use such images. Due to tight compute availability dynamically fluctuating around 60%–70% (with optimal daily throughput windows spanning roughly 6–7 hours), programmatical API integration with automated retry and polling logic is strongly recommended.

Seedance 2.5 Image-to-Video is a multimodal video generation tool based on reference images, supporting video editing and extension capabilities.

Seedream 5.0 Pro is ByteDance's flagship image generation and visual synthesis model built on the next-generation Seedream 5.0 architecture. Engineered for high-end digital design and cinematic asset production, it features advanced text-to-image synthesis, multi-image subject alignment, and hyper-realistic lighting physics. Seedream 5.0 Pro supports dynamic aspect ratios and native high-definition rendering up to 2K, ensuring crisp typography rendering, flawless skin textures, and precise photorealistic details. It serves as an enterprise-grade solution for commercial advertising, game conceptual art, digital marketing campaigns, and professional studio workflows.

Seedream 5.0 Pro Edit "Spicy" mode is a high-performance image processing model built upon ByteDance’s next-generation image editing and inpainting architecture, Seedream 5.0 Pro Edit. The model excels at precisely identifying subject boundaries and image textures, supporting high-precision local inpainting, subject replacement, consistency maintenance across multiple reference images, and complex style transfer. As an unrestricted model, the "Spicy" version removes standard censorship mechanisms, granting visual creators complete freedom for artistic expression.

Seedream 5.0 Pro Text to Image Spicy (High Saturation/Dynamic Range Edition) is a uncensored and professional-grade AI text-to-image model variant by Seedream AI, dedicated to extreme visual impact. Building upon the professional detail and control of the 5.0 Pro series, the Spicy edition is fine-tuned for maximized color saturation, dynamic range (HDR), dramatic lighting contrast, and powerful visual tension.

Built on the Seedance 2.0 video architecture, Seedance 2.0 Spicy combines fluid cinematic motion, precise camera control, and unrestricted uncensored visual synthesis.

Seedance 2.0 Economy engineered as a high-value supplementary pipeline for large-scale cost reduction, its transparent pricing model charges exclusively on output duration (in seconds), with zero fees for input videos. Whenever connected, it maintains exceptional motion stability and native audio synchronization. Due to tight compute availability dynamically fluctuating around 60%–70% (with optimal daily throughput windows spanning roughly 6–7 hours), programmatical API integration with automated retry and polling logic is strongly recommended. Seedance 2.0 Economy efficiently powers high-volume e-commerce product videos, automated social media content matrices, and low-cost ad creative pipelines.
