Segmind Release Notes (September 21–27, 2026)

1. Model Pages — Resources and Per-Model Prompting Guides

• What's new: Model pages now carry a Resources tab beside About and Guide, listing the files attached to that model with their format and size. The first of these are prompting guides for flux-1.1-pro and p-image — short, model-specific write-ups on what each one responds to, what to avoid, and how to phrase a prompt for it. This is the same document the playground's Refine action reads when it rewrites your prompt, so the guidance the model is given is now guidance you can read. A model with no attached files does not show the tab.
• Impact: The advice that used to sit behind the Refine button is readable directly, so you can write a good prompt yourself rather than round-tripping through the rewriter to find out what a model likes.
• Released: September 21, 2026

2. Seedance 2.5 — Draft Mode

• What's new: Send "draft": true to POST /v1/seedance-2.5 and you get a fast, low-cost 480p preview plus a task id. When you like the shot, pass that id to POST /v1/seedance-2.5-draft-final as draft_task_id and the same generation is re-rendered at 1080p. A draft can be finalized for 7 days; the final render is billed at the 1080p rate. In the playground and Pixelflow, a draft result shows its task id as a copyable value with a Render final in 1080p action, and you can wire draft → final as two nodes in a flow.
• Impact: Iterate on prompts and motion at preview cost, and only pay for full-resolution output on the takes you keep.
• Released: September 25, 2026

3. Seedance 2.x — Choose Your Output Codec

• What's new: A new output_codec parameter on the Seedance 2.x family controls how the video is delivered. Leave it out (or set auto) to receive the model's own encode byte-for-byte — the default and unchanged behavior. Set h264 to have the file re-encoded to H.264 whenever the model returns HEVC. An unrecognized value is rejected at submit time, before anything is billed. Separately, Pixelflow now shows an explanatory placeholder for a video your browser can't decode, instead of an empty player bar.
• Impact: If your viewers are on browsers that don't play HEVC (for example Chrome or Firefox on Windows), ask for h264 and the file plays everywhere; if you're post-processing the file yourself, you keep the original untouched.
• Released: September 21–23, 2026

4. New Models — Recraft V4 and Wan 3.0 Prime

• What's new: The Recraft V4 family is live in four variants: recraft-v4 (text-to-image with accurate in-image text for design work), recraft-v4-svg (editable SVG vectors for logos, icons and illustrations), recraft-v4-pro (print-ready 2K design images) and recraft-v4-pro-svg (higher-quality editable vectors). Also new is wan3.0-video-prime, an accelerated Wan 3.0 video model at 480p, 720p and 1080p that runs roughly 1.4× faster than standard Wan 3.0, with native audio and lip-sync. All are on the API and selectable in the playground; per-request pricing is on each model's page.
• Impact: Vector-native, text-accurate design generation for brand and print work, and a faster route to Wan 3.0 video when turnaround matters.
• Released: September 24–27, 2026

5. Public Model Catalog API

• What's new: GET https://api.segmind.com/models returns the full Segmind catalog — no API key required. Each entry includes the slug, name, description, category, input/output modality, provider, average cost, typical latency, a popularity score and the model's parameter schema. The list can be filtered server-side (q, input, output, provider, min_cost/max_cost, max_latency, created_after, is_new, slugs) and sorted by popular, newest, name, cheapest, fastest or relevance; add facets=true to get counts per category, modality and provider for building filter UIs. Look up a single model with GET https://api.segmind.com/model/<slug>. Requests are rate-limited per IP.
• Impact: Build model pickers, availability checks or "cheapest video model that takes an image" queries straight against the live catalog, without scraping pages or hard-coding slugs.
• Released: September 24–26, 2026

6. Generation History — Cost, Prompts and Full CSV Export

• What's new: GET /inference-request/generations now returns each request's status, its cost (credits_deduction, in USD), the prompt and the full parameters, alongside the ids and output URLs it already returned — existing fields are unchanged. In the console, Export CSV on the Generations page now exports every request matching your current filters (up to 10,000, one sheet per model) with all parameters, not just the rows visible on screen.
• Impact: Reconcile spend per generation and reproduce any past result from your own records, whether you pull history through the API or download it from the console.
• Released: September 23, 2026

7. Pixelflow Improvements

• What's new: Files you upload into a workflow's input nodes are now saved to your asset library when you save or publish, so published flows and templates keep working after temporary upload links expire — existing workflows have been migrated. Published workflow APIs now pass through every setting on an LLM node (for example web_search: true on Gemini), so a published flow behaves exactly like it does in the editor. Dropdown, number and toggle defaults on older nodes are now sent correctly (Bria Expand's aspect_ratio works on first run), and on phones the editor opens with the models panel closed and the toolbar no longer covers the workflow title. Bundle pages have been redesigned so each bundle lists every included workflow, with featured ones marked.
• Impact: Published Pixelflow APIs are more reliable and match what you built, and workflows are easier to edit on mobile and to browse in bundles.
• Released: September 23–26, 2026

8. Playground and Account

• What's new: Every playground output now has an info button that opens a generation details panel — the same view as in the console — and timings that weren't recorded are omitted rather than shown as "0.0s". The OAuth consent screen explains the keys:write permission in plain language ("create and revoke API keys", without being able to read existing keys). Links into the console now survive sign-in, so a top-up link opens checkout after you log in, and old cloud.segmind.com/console/… links redirect to the matching page on platform.segmind.com. The sidebar plan card's Upgrade button now opens the plan picker directly.
• Impact: Fewer dead ends — bookmarks, emailed links and third-party "connect your Segmind account" flows land where they should, and you can see exactly how any playground result was produced.
• Released: September 21–27, 2026
