OpenAI adds transparent background generation to GPT-Image-2 API preview

OpenAI said on August 21 that GPT-Image-2 now supports transparent background generation in preview through its API, giving developers a way to return images with an alpha channel by setting the background parameter to "transparent." The update restores a feature that had been missing from GPT-Image-2 since its April 21 release and early-May developer rollout, even though the older gpt-image-1 had supported transparent output since April 2025. Before this preview, developers had to rely on workarounds. Some downgraded to older models such as gpt-image-1.5 or sora_image. Others added background-removal tools like RemBG, BiRefNet, or 851-labs' background-remover, adding 1 to 3 seconds per image. More complex methods included generating green-screen backgrounds or creating the same image twice on different backgrounds and subtracting the results, which doubled generation costs. The report also outlined GPT-Image-2 pricing at roughly $0.03 for 1K, $0.05 for 2K, and $0.08 for 4K images. For a 1024×1024 image, output can range from 272 tokens at low quality to 4,160 tokens at high quality, with output priced at $30 per million tokens. The feature remains in preview and comes with limits. Early testers said alpha values landed at 253 to 254 instead of a fully opaque 255, edge halos could appear around subjects, and the edit endpoint might not preserve transparency from source images. Transparent output is currently limited to PNG and WebP, while OpenAI has not disclosed any preview-specific pricing differences or usage caps.

SenseTime unveils SenseNova U1 Pro at WAIC 2026 with native 8K output and a delivery-focused image workflow

SenseTime introduced SenseNova U1 Pro at WAIC 2026, positioning it as a system for complex multimodal delivery rather than a model built only for single-pass image generation. According to the event presentation and the original report by QbitAI cited by MarsBit, U1 Pro is designed to handle a full chain of tasks around a target outcome: understanding, planning, information organization, multimodal generation, checking, revision and final delivery. The launch demo centered on an ultra-long 8K image themed around the ninth anniversary of WAIC from 2018 to 2026. The report said the original file was 51 MB and remained legible when enlarged. It summarized U1 Pro’s core strengths in three parts: native 8K generation that preserves text, layout and detail on very large canvases; a text-and-image interleaved workflow that can move from sketching to refinement, coloring, checking and adjustment; and a product focus on deliverable outputs for use cases such as infographics, urban planning, film storyboards, academic posters and commercial design. The article also described four practical tests, including a 24 solar terms panoramic image, a laboratory-style visual poster, a glazed-texture traditional landscape with futuristic architecture, and an original movie poster intended to look ready for commercial use. SenseTime CEO Xu Li summarized the broader issue this way: “Being interactive does not mean being deliverable.”
