API Updates

GPT Image 2 Beta Parameter Limits

• Supported: size="auto", or aspect-ratio sizes such as size="1:1" with resolution="1K"
• Auto mode: size="auto" remains supported; if a resolution value is also sent, it is ignored
• Not supported on Beta: resolution="2K", resolution="4K", or explicit WxH pixel sizes such as 1024x1024
• Recommendation: switch to official gpt-image-2 for 2K, 4K, or explicit pixel control

GPT-4O Image Compatibility Migration

GPT-4O Image has reached model retirement, so its compatibility route has been migrated to GPT Image 2 Beta to keep requests available.

• gpt-4o-image and gpt-4o-image-beta now route to gpt-image-2-beta internally.
• Existing requests can continue using the same model IDs for compatibility.
• Billing and routing now follow the GPT Image 2 Beta configuration.
• If size is not provided, the compatibility route keeps the previous square-image default (1:1).
• The mask / mask_url parameter no longer takes effect on this compatibility route; use image_url / image_urls with the prompt for editing-style workflows.

GPT Image 1.5 Legacy Compatibility Migration

The gpt-image-1.5-beta and gpt-image-1.5-lite compatibility routes have been migrated to GPT Image 2 Beta to keep requests available.

• Existing requests can continue using the same model IDs for compatibility.
• Legacy pixel sizes are converted to GPT Image 2 Beta supported aspect-ratio sizes with 1K resolution.
• The quality level parameter no longer takes effect on this compatibility route and will be ignored.
• Billing and routing now follow the GPT Image 2 Beta configuration.

Due to an upstream access-policy change on Anthropic's side, Claude Fable 5 (claude-fable-5) is temporarily unavailable. We're actively working to restore it and will share a recovery timeline as soon as we have one.

In the meantime

• Alternative: switch to Claude Opus 4.8 — also 1M context, with the same API surface as Fable 5, so migration is just a model-ID swap
• Scope: only claude-fable-5 is affected; the rest of the Claude line (Opus / Sonnet / Haiku) remains fully available
• Updates: we'll post the recovery notice here in the ChangeLog as soon as it's back

We apologize for the inconvenience.

GPT Image 1 and GPT Image 1.5 (Official) have migrated from flat per-image pricing to granular token-based billing, aligned with OpenAI's upstream usage reporting.

What Changed

• GPT Image 1 now uses 5-dimension token billing: Image Output, Image Input, Image Cached Input, Text Input, Text Cached Input. Output Text + Thinking is included at no extra charge.
• GPT Image 1.5 Official now uses 6-dimension token billing: same 5 dimensions plus a dedicated Output Text + Thinking dimension (typically less than 1% of total cost).
• GPT Image 1.5 Beta (Lite variant) remains unchanged at flat per-request billing.

Why It Matters

• Pricing now reflects actual resource consumption per request instead of a single flat fee.
• Low-quality / small-size generations cost significantly less; high-quality / large-size generations with many reference images cost more.
• Usage logs now display a full token breakdown by dimension, making cost attribution transparent.

     • Sora with watermark: ~$0.023/time

     • Sora watermark removal: ~$0.037/time

• Supports uploading reference images, please see the document for specific parameters and calling methods: Sora 2 Document​

Risk control tips (reference picture)

• OpenAI official review of reference images is extremely strict.

• Reference pictures containing real-life photos are likely to fail in the review. It is recommended to give priority to non-real-life pictures such as animations, landscapes, and concept pictures to increase the success rate.

• The Sora channel has been fully restored, and early instability issues have been investigated and fixed.

• In order to ensure the long-term stability of the service, fees will be officially charged starting from October 5th:

  • VIP price: ~$0.023/time

  • Non-VIP price: ~$0.113/time

• Review: In order to allow VIPs to experience it first, an ultra-low discount price of ~$0.000 has been provided for 3 consecutive days.

• Based on the experience in recent days, we will continue to upgrade interface services to improve stability and experience.

• Sora 2 API is open for use, non-VIP price: ~$0.098/time.​

• VIP benefit price on October 2nd: ~$0.000/time.

• If you have connected other video models, it only takes a few minutes to switch to Sora 2. Access the documentation: Sora 2 Documentation​

• Note: Sora 2 takes about 5 minutes to generate, please reserve sufficient time in the business logic.

Sora 2 Stability and Risk Control Instructions

• The Sora success rate was monitored at night to be about 88.24%, and the overall channel is still limited by the fact that the official stable interface has not been officially opened.

• From October 3rd, the VIP price will continue to be maintained at ~$0.000/time to reward users.

• Current failures are mostly focused on content review. Sora has strict risk control, and prompt words containing mild pornography, horror and other elements are prone to failure.

• It is recommended to optimize the prompt words. If the failure rate is still high for reasons other than risk control, you can contact the official to join the exclusive technical support group.
