Changelog

​

New video model

• wan3.0-video adds Alibaba audiovisual generation with text-to-video, first/last-frame image-to-video, up to 1080P and 30-second output, and optional synchronized audio.
• Video pricing is billed by generated milliseconds and varies by resolution; see Video pricing for the current rates.

​

Chat catalog refresh

• Added gpt-6-luna, gpt-6-sol, claude-fable-5, claude-fable-5-1, claude-opus-5, claude-opus-5-5, and claude-sonnet-5.
• Removed gemini-2.5-pro, which is no longer returned by the current public model catalog.
• Refreshed Chat pricing for the updated catalog.

​

Schema updates

• model is now explicitly required for gemini-2.5-flash-image, seedance-2-0, and wan2.6.
• gpt-image-2.5-flare and gpt-image-2.5-sunburst no longer document the unsupported response_format field.

​

GPT Image 2 schema update

• gpt-image-2 now documents extends.edit.mask for local image editing; transparent mask areas are regenerated and the field is used together with images.
• The unified image-generation endpoint continues to require model as its routing key.

​

Gemini video understanding

• Added a video understanding with Gemini guide covering upload session creation, direct file upload, processing status, native generateContent, and cleanup.
• Added API Reference pages for the Gemini-only file lifecycle and native multimodal request.
• Gemini file URIs are not reusable across OpenAI, Anthropic, generation, or compatibility endpoints.
• Validated the workflow end to end with gemini-3.1-flash-lite and added portable filenames, complete upload headers, gateway error details, and automatic cleanup guidance.

​

New image models

• gpt-image-2.5-sunburst — precision-focused image generation and editing with up to 16 reference images, mask-guided edits, custom dimensions, and transparent backgrounds.
• gpt-image-2.5-flare — fast image generation and editing with the same reference-image, mask, custom-size, quality, and transparent-output controls.
• Both models support text-to-image and image-to-image workflows through POST /v1/images/generations; cached text input starts at $0.9375 / 1M tokens.

​

Catalog and pricing updates

• Added gpt-6-astra to the Chat model catalog and pricing page.
• gemini-3.1-flash-lite-image — starting price drops from 0.25 → 0.1875 USD / token.
• Removed sora-2 from the video pricing table because it is no longer returned by the current public pricing source; its API Reference page remains available.

​

New video models

• seedance-2-0-fast — adds a low-latency Seedance option for 4–15 second multimodal video generation, with image, video, and audio references.
• seedance-2-0-mini — adds a lightweight Seedance option for high-volume video generation and editing workflows.

​

Updated schemas and model catalog

• seedance-2-5 — intelligent duration (-1) is now the default; reference inputs are exposed consistently as images, videos, and audios.
• MiniMax-Hailuo-02 — prompt is now optional, matching image-conditioned generation workflows.
• Added glm-5.2 and glm-5.3 to the current Chat model catalog.
• Removed the stale gemini-3-pro-image-preview and gemini-3.1-flash-image-preview pages because these models are no longer returned by the public catalog.

​

Resource-oriented generation API

• Use POST /v1/images/generations and GET /v1/images/generations/{task_id} for image generation.
• Use POST /v1/videos/generations and GET /v1/videos/generations/{task_id} for video generation.
• Use public GET /v1/models to discover the currently visible model catalog without a Bearer API key.
• Existing /v1/image-generation, /v1/video-generation, and historical query routes remain supported. See Legacy API compatibility for the complete mapping.
• Output asset URLs are dynamically signed. Avoid long-term URL caching, and do not blindly retry create requests after an uncertain timeout.

​

Model catalog sync

• Added gemini-3-pro-image, gemini-3.1-flash-image, and MiniMax-H3 from the current upstream catalog.
• Removed the stale seedance-v1.5-pro reference because it is no longer returned by the visible model source.
• Refreshed starting prices for seedream-4.5 (0.029040 USD/image), seedream-5.0-lite (0.030305 USD/image), seedream-5.0-pro (0.045000 USD/call), and wan2.6 (0.304850 USD/call).

​

Seedance 2.0 schema update

• seedance-2-0 — adds an images array with up to 9 reference inputs.
• prompt now accepts up to 2,500 characters, reduced from 5,000. Update clients that validate or send longer prompts.

​

New model

• seedance-2-5 — ByteDance’s Seedance 2.5 supports text-to-video and image-to-video generation up to 30 seconds, synchronized audio, and image, video, or audio references through the unified video generation API. Starting from 6.08 USD / token.

​

Seedance 2.0 parameter update

• seedance-2-0 — prompt now accepts up to 5,000 characters.
• duration now supports 14s and 15s generations.
• resolution now includes 1080P and 4K options.
• prompt is no longer marked as required, matching image-to-video and media-conditioned workflows.

​

Schema upgrade — richer model parameter docs

• Enum dropdowns for size, resolution, quality — Playground renders select boxes instead of free-text inputs.
• Default values shown next to each field (e.g. seedance-2-0.resolution defaults to 720P).
• Conditional rules spelled out where they apply — e.g. on minimax-hailuo-02 the resolution field now documents the three rules that constrain it (duration, first_frame_image, last_frame_image).
• Field ordering reflects how parameters are typically filled in, not alphabetical.
• gpt-image-2 — previously missing the required model field in the schema; now present.

​

Chat endpoints — removed unsupported params

• OpenAI Chat Completions: model, messages, stream, max_tokens, stop
• Anthropic Messages: model, messages, max_tokens, system, stream, stop_sequences

• seedance-2-0 — starting price now listed: 3.87 USD / token.

​

New model

​

Updated models

• gpt-image-2 — now accepts up to 10 reference images for image-to-image.
• seedance-2-0 — adds new audios, first_frame_image, last_frame_image, and videos inputs.

​

Heads up — API base URL changed

​

New models

• gpt-image-2 — OpenAI’s next-gen image model, now available through the unified POST /v1/image-generation endpoint.
• seedance-2-0 — Bytedance Seedance 2.0, available through POST /v1/video-generation.

​

Other updates

• Pricing — kling-v3 now bills per second of generated video instead of per call.
• Changed — sora-2 now accepts a resolution parameter. Minor field-description refreshes on the historical gemini-3-pro-image-preview model, kling-v3, and minimax-hailuo-02.
