GlobalAI OPC gives you access to a curated set of best-in-class AI models across three categories: video generation, image generation, and text & chat. All models are available through a single unified API gateway using standard Bearer token authentication, so you can switch between providers without changing your integration structure.Documentation Index

|---|---|---|---|---|
| Sora (OpenAI) | openAiSora2Plus, openAiSora2Pro | 1280×720 | 4, 8, 12s | Image-to-video supported; max 1 reference image |
| VEO (Google) | veo_3_1_fast, veo_3_1_pro, veo_3_1_fast_stable, veo_3_1_pro_stable | Up to 4K | Varies by variant | Reference images and first/last frame control supported |
| Seedance 1.5 (ByteDance) | seedance_1_5_pro_480p, seedance_1_5_pro_720p, seedance_1_5_pro_1080p | 480p – 1080p | 2 – 12s | Audio generation supported |
| Seedance 2.0 (ByteDance) | seedance_2_0, seedance_2_0_fast, seedance_2_0_pro, seedance_2_0_fast_pro | Varies by variant | 4 – 15s | Multi-modal reference input; asset library management required for faces |
| Vidu | viduq3-pro, viduq3-turbo | 540p – 1080p | 1 – 16s | Flexible duration; first/last frame support |
| Grok (xAI) | grok_video3, grok_video3_pro, grok_video3_max, grok_video3_stable | 480p – 720p | 6 – 30s | Up to 7 reference images for image-to-video |
| StarVideos O3 | starvideos_o3 | Varies | 3 – 15s | Video reference input supported |
| Videos | videos, videos_fast | 720p | 4 – 15s | Standard and fast-tier variants |
| SD2 Manxue | sd2_manxue_720p, sd2_manxue_1080p, sd2_manxue_2k, sd2_manxue_4k, sd2_manxue_fast_720p, sd2_manxue_fast_1080p | Up to 4K | 4 – 15s | Audio reference supported; asset review required for sensitive content |
Image Generation Models
GlobalAI OPC supports two image generation model families, both capable of high-resolution output from text prompts and optional reference images.| Model Family | Model Variants | Max Resolution | Aspect Ratios | Notes |
|---|---|---|---|---|
| Nano Banana | nano-banana, nano-banana-2, nano-banana-pro, nano-banana-2-stable, nano-banana-pro-stable | Up to 4K | Multiple ratios supported | Up to 6 reference images for style or subject guidance |
| GPT Image 2 (OpenAI) | gpt-image-2, gpt-image-2-r | Up to 4K | Multiple ratios supported | Quality tiers: low, medium, high; up to 16 reference images |
Text & Chat Models
Text and chat APIs use a synchronous request/response pattern — no polling required. GlobalAI OPC exposes three API protocols to maximize compatibility with existing SDKs and tools.| API Protocol | Supported Models |
|---|---|
OpenAI Chat API (/v1/chat/completions) | GPT-5.4, GPT-5.5, all Claude variants, all Gemini variants |
| Claude Messages API | Claude Haiku 4-5 through 4-7, Claude Sonnet 4-5 through 4-7, Claude Opus 4-5 through 4-7, GPT-5.4, GPT-5.5 |
| Gemini Native API | Gemini 2.5 Flash Lite, Gemini 2.5 Pro, Gemini 3 Flash, Gemini 3.1 Pro |
Choosing the Right Model
I need the fastest video generation
I need the fastest video generation
Use
videos_fast, viduq3-turbo, or seedance_2_0_fast for the lowest latency. These fast-tier variants sacrifice some output quality in exchange for significantly shorter generation times — ideal for prototyping or high-throughput pipelines.I need the highest video quality
I need the highest video quality
Use
sd2_manxue_4k for 4K output, veo_3_1_pro for Google’s highest-quality tier, or seedance_2_0_pro for ByteDance’s professional tier. These models produce the best results but take longer to generate.I need to generate video from an image

All of the following model families support image-to-video (providing one or more reference images to guide the generated video): Sora, VEO, Seedance 1.5 & 2.0, Vidu, and Grok. Grok supports up to 7 reference images in a single request. For face-based or sensitive imagery, use Seedance 2.0 or SD2 Manxue with the asset management workflow.
I need long video duration
I need long video duration
Use Grok (
grok_video3, up to 30 seconds) for the longest possible output. Vidu supports up to 16 seconds with flexible per-second duration control. Most other models cap out at 12–15 seconds.I need to use the OpenAI Python or Node.js SDK

Point your SDK’s
base_url at the GlobalAI OPC endpoint and use the OpenAI Chat API protocol. This gives you access to GPT, Claude, and Gemini models all through the familiar openai.chat.completions.create() interface without changing your existing code structure.
