   ByteDance Introduces Seedream 5.5 for Professional Image Production

   ByteDance Seed introduces Seedream 5.5, an image generation model for professional production workflows. ByteDance says it preserves unchanged image areas at the pixel level across up to 100 editing rounds without color shifts, and generates native RGBA images with transparent backgrounds. The model is gradually rolling out via Jimeng, Doubao, Doubao Work, and Volcengine Ark; a Pro version is planned.

   ByteDance Releases Seedream 5.5 for More Stable Image Editing

   ByteDance’s Seed team released the Seedream 5.5 image model on November 9, with editing that can keep unchanged areas pixel-level stable and generate images with transparent backgrounds. The post reports a severe text error rate of 0.4%, down from 2.8% in the previous generation, and says editing realism trails Nano Banana 2.1 by about 6%. Seedream 5.5 is rolling out across Jimeng, Doubao, and Doubao Work; developers can try Doubao-Seedream-5.5 on Volcano Engine Ark.

   Testing Seedream 5.5 for Stable Image Editing and a Talking Avatar

   Baoyu tests ByteDance’s Seedream 5.5 by generating a talking cartoon avatar from 12 images and repeatedly editing a detailed tourist photo. In the avatar test, all 11 edited images met the author’s pixel-difference criteria; in the photo test, eight of 10 rounds left untouched areas pixel-identical to the prior image. The article also reports mixed-language text results, opaque glass in a transparent-background image, and a successful pose-reference test.

   NVIDIA Introduces GR00T 2 and Robotics Simulation Tools at CoRL

   NVIDIA introduced GR00T 2, an open world action model, alongside robotics simulation tools, benchmarks and agentic workflows at CoRL. The post reports that GR00T 2 completed 40 of 50 evaluated tasks at least once without task-specific demonstrations and achieved 95% average success with five demonstrations per task. Isaac Lab 3.0 with Newton achieved up to 2.5x the training throughput of Isaac Lab 2.3 with PhysX in a vision-based dexterous manipulation benchmark.
