Segmind Release Notes (August 10–16, 2026)

1. New Models — Object Extraction and Layer Decomposition

• What's new: Two new image models are live on the API. bria-extract-object isolates a single named object from an image using a text prompt and returns an RGBA PNG cutout with soft alpha edges. seedream-5-pro-layer-decomposition takes one image and returns a base image plus up to 16 transparent PNG element layers, each with its stacking order, bounding box, and name.
• Impact: Pull one subject cleanly out of a photo, or break a finished composition back into editable layers, without a manual masking pass in an image editor.
• Released: August 12, 2026

2. LTX 2.5, Grok Imagine Image 2, and Legacy LTX Slugs

• What's new: ltx-2.5-fast, ltx-2.5-pro, and grok-imagine-image-2 are live on the API. The legacy ltx-2-* slugs now resolve to LTX 2.3 ahead of LTX 2's August 15 end of life, so calls still pointing at the old slugs keep working.
• Impact: Call the newer LTX tiers directly, and keep existing LTX integrations running without an emergency change on your side.
• Released: August 14, 2026

3. Playground — Layer Gallery, Annotated Inputs, and Shot Chaining

• What's new: The playground supports seedream-5-pro-layer-decomposition with a layer gallery that shows each returned PNG alongside its z_index and bounding-box manifest, plus a new annotatable image input — circle or scribble on the source image and the marks are flattened into what the model sees. For Seedance 2.x, the last frame of a generated clip is now surfaced as a labelled artifact in the output gallery and feeds directly into the next clip's first_frame_url.
• Impact: Point the model at exactly what you mean by marking up the image, inspect decomposed layers one at a time, and chain shots together by carrying the last frame of one clip into the start of the next.
• Released: August 12–13, 2026

4. Clearer API Errors and Stricter Request Validation

• What's new: Video-model failures now return a specific, actionable reason — for example, a source image whose height falls outside the accepted range — instead of one generic "reference media could not be prepared" message. Provider-side error output is normalised into clean Segmind error responses, and transient faults are marked as retryable. On the validation side, seedance-2.5 submissions now resolve aspect-ratio and task-type constraints automatically instead of being rejected, and wan2.7-r2v caps duration at 10 seconds when the reference material includes a video and rejects out-of-range or non-numeric durations with a clear 400.
• Impact: Read the error, fix the input, and retry — instead of guessing which part of your request was rejected. A request that can't run tells you so up front rather than running at a duration you didn't ask for.
• Released: August 11, 2026

5. API Code Samples Now Use x-api-key

• What's new: Every API code sample — curl, Python, JavaScript, Go, PHP, and Ruby, across the model, Pixelflow, LLM, and AI gateway tabs — now authenticates with the x-api-key header. SG_ keys authenticate with x-api-key, not Authorization: Bearer.
• Impact: Copy a sample straight out of the playground and it authenticates on the first try, instead of returning a confusing 401.
• Released: August 16, 2026

6. Per-Team-Member Usage and Cost Visibility

• What's new: The /request-history and /generations endpoints accept optional user_id and user_email filters and now return who made each request. In the console, generations can be filtered by team member across the table, grid, mobile, and CSV export views, and the Source filter now offers only the values the API actually accepts. The cost-analytics "Cost by Team Member" card explains when it requires team-admin access rather than rendering blank, and cost analytics loads reliably regardless of the shape of the response.
• Impact: See which teammate ran which generation, and break usage and spend down per person from either the API or the console.
• Released: August 14–16, 2026

7. Pixelflow — Partner Publishing and Editor Reliability

• What's new: External affiliate partners can now publish Pixelflow workflows with a callable API, and a template's private, playground, and API visibility settings now drive the tabs shown on its page. Templates without a playground snapshot show the Workflow canvas tab instead of an empty state. In the editor, a new "Run as API" mode simulates a published run on the canvas, publish-compatibility warnings flag blockers before you publish, each node keeps its own model's output type, {{ }} references to deleted nodes are cleaned up automatically, and workflow cards fall back to a placeholder icon when a thumbnail is unavailable.
• Impact: Publish a workflow as an API that others can call, and see how it will behave — and what would block it — before you ship it.
• Released: August 13–15, 2026

8. Coming Soon Model Pages and Google Sign-In

• What's new: Models can now appear on segmind.com/models before they're runnable, with a "Coming Soon" pill, a dedicated pre-launch page, and a disabled playground. Separately, Google sign-in now completes reliably, and an interrupted sign-in lands on a recoverable retry notice on the console login page instead of a dead end; old /login bookmarks route to the current login page.
• Impact: See what's landing next and bookmark the page before a model goes live, and sign in with Google without getting stuck.
• Released: August 13–15, 2026
