⚠️ gpt-image-2-vip size is unavailable again; output is temporarily limited to 1K

June 23, 2026

Temporary gpt-image-2-vip size parameter update
  • Based on customer reports, live testing, and code-level review this morning, default-group gpt-image-2-vip lost the restored size behavior again after another upstream rule change
  • gpt-image-2-vip currently generates 1K images normally; the submitted size value is silently ignored, so 2K / 4K cannot be selected through this route for now
  • The gpt-image-2-vip model name and $0.03/call per-request billing remain unchanged
  • For 2K / 4K or precise size control, switch to official-forward gpt-image-2 under the Sora2Official or GPTImage2 Enterprise group
  • Official-forward gpt-image-2 supports 4K / 2K and precise size control; it is billed by official input / output tokens, not by default-group per-call pricing
  • The June 18, 2026 restoration notice is superseded by this announcement
  • 📝 Developer documentation:
Do not rely on default-group gpt-image-2-vip for production 2K / 4K output right now. Even if your request body still sends size, the route may return a 1K image.

🎨 gpt-image-2-vip Size and Quality Parameters Restored (Historical Notice)

June 18, 2026

Historical gpt-image-2-vip parameter capability update
This announcement is historical and is superseded by the June 23, 2026 notice. gpt-image-2-vip can currently generate 1K output reliably, but submitted size values are temporarily ignored.
  • This entry describes the short-lived restoration state on June 18, 2026; it is no longer current
  • At that time, default-group gpt-image-2-vip temporarily restored size support
  • Common explicit 1K, 2K, and 4K pixel sizes were supported, including 1024x1024, 1536x1024, 2048x2048, 2048x1152, 3840x2160, and 2160x3840
  • The gpt-image-2-vip model name and $0.03/call per-request billing remain unchanged
  • For current 2K / 4K or precise size control, use official-forward gpt-image-2
  • 📝 Developer documentation:
Default-group gpt-image-2 still does not support size / quality. Default-group gpt-image-2-vip is also not a current 2K / 4K size-control route. When you need size and quality parameters, use gpt-image-2 under the Sora2Official / GPTImage2 Enterprise groups.

⚠️ sora-2 and sora-2-pro Official-Forward Models Will Be Retired on July 1

June 17, 2026

Sora 2 official-forward route retirement notice
  • Due to upstream OpenAI compute allocation changes, the sora-2 and sora-2-pro official-forward routes have recently experienced severe timeout issues and no longer meet production stability expectations
  • LaoZhang API will stop maintaining and retire the sora-2 / sora-2-pro official-forward models on July 1, 2026
  • Although the official retirement timeline may point to September 2026, these routes are already frequently unstable, so we do not recommend new integrations or production workloads
  • Existing users should migrate as early as possible; currently recommended alternatives are wan-2.7 and SeeDance2 / Seedance 2.0
  • 📝 Migration reference:
After July 1, sora-2 and sora-2-pro official-forward routes will no longer be maintained as stable entry points. Move production jobs ahead of time to avoid timeout or task failure impact.

⚠️ gpt-image-2-vip Size Parameter No Longer Supported (Historical Notice)

June 16, 2026

gpt-image-2-vip parameter support update
This is a historical notice. gpt-image-2-vip briefly restored size on June 18, 2026, but the latest state is the June 23, 2026 notice: size is unavailable again and reliable output is currently limited to 1K.
  • This entry describes the temporary parameter adjustment on June 16, 2026
  • The gpt-image-2-vip model name and $0.03/call per-request billing remain unchanged
  • Current status: default-group gpt-image-2-vip lost size support again; submitted size is silently ignored, and 2K / 4K cannot be selected
  • Default-group gpt-image-2 still does not support size / quality
  • Use gpt-image-2 under the Sora2Official or GPTImage2 Enterprise group when you need full official Images API parameter compatibility
  • 📝 Developer documentation:
This section is historical. For current behavior, use the June 23, 2026 announcement and the GPT Image 2 API documentation.

📅 May 2026

🎬 Veo 3.1 Official API Forwarding Is Live With Low Unified 4K Pricing

May 21, 2026

Veo 3.1 official-forward route update
  • 🚀 New models:
    • veo-3.1-fast-generate-preview
    • veo-3.1-generate-preview
  • 💵 Pay-per-request billing:
    • veo-3.1-fast-generate-preview: $0.3/call
    • veo-3.1-generate-preview: $1.2/call
    • Set Billing mode to Pay-per-request when creating the token
    • Supported combinations use one unified price with no resolution surcharge; use 8 seconds for production integrations, and 1080p / 4K require 8 seconds
  • 📉 4K pricing advantage:
    • Based on Google’s 8-second 4K official price, Fast goes from about $2.40 to $0.3/call
    • Standard goes from about $4.80 to $1.2/call
    • 4K requests use unified pricing; verify final resolution from the downloaded MP4 metadata
  • 📝 Developer documentation:
The new route uses the same OpenAI Videos API style as Sora2 official forwarding: POST /v1/videos to create a task, GET /v1/videos/{id} to poll status, and GET /v1/videos/{id}/content to download MP4 bytes. The legacy-route incident notice still applies to old model names such as veo-3.1, veo-3.1-fast, and veo-3.1-fl; use the official-forward model names above for new integrations.

⚠️ Veo-3.1 Legacy Route Temporarily Unavailable

May 14, 2026

Veo-3.1 route incident notice
  • The veo-3.1 series legacy route began experiencing failures on May 14, 2026
  • The legacy route is temporarily unavailable; pause new calls and production integrations for now
  • Existing users should follow later announcements; recovery timing will be announced on this page and in the console
During this incident, do not use veo-3.1, veo-3.1-fast, veo-3.1-fl, or other Veo-3.1 legacy-route variants for production workloads.

🛡️ GPTImage2 Enterprise Pure Official-Key Group Is Live

May 13, 2026

GPT Image 2 official-compatible group update
  • New GPTImage2 Enterprise group: pure official-key routing with enterprise concurrency support
  • Billing is official pricing +20% to cover tax and operating cost, not profit markup
  • Sora2Official remains available as a mixed AZ + official-key transit group
  • Both official-compatible groups use model="gpt-image-2" with Images Generations and Images Edits
For quick testing or default-group routes, you can keep using default-group gpt-image-2 / gpt-image-2-vip. For official parameter compatibility and higher stability, choose GPTImage2 Enterprise.

🎨 gpt-image-2-vip Size Parameter Historical Notice

May 1, 2026

gpt-image-2-vip size capability update
This announcement preserves the historical state from May 1, 2026. gpt-image-2-vip stopped supporting size on June 16, briefly restored it on June 18, and lost it again on June 23. Current reliable output is 1K, and submitted size values are silently ignored.
  • Parameter update:
    • gpt-image-2-vip now supports 1K, 2K, and 4K size tiers
    • 30 explicit pixel sizes are supported across square, portrait, landscape, widescreen, and ultrawide ratios
    • Pass an explicit pixel value such as 2048x2048, 3840x2160, or 2160x3840
    • Current status: size is unavailable again, so 2K / 4K cannot be selected through this route
  • 🧩 Integration notes:
    • gpt-image-2-vip supports size
    • gpt-image-2-vip currently generates 1K normally; submitted size is silently ignored
    • Use gpt-image-2 under the Sora2Official mixed AZ + official-key group, or use the new GPTImage2 Enterprise pure official-key group when you need quality, 2K / 4K, or full official parameter compatibility
  • 📝 Developer documentation:
This historical announcement records the gpt-image-2-vip size-parameter capability update at that time. It does not change the April 22 announcement for the initial GPT-Image-2 default-group route launch.
