VISION MODELS
Text-to-image, image-to-video, inpainting, video editing — one API routes every task to the best-fit model. No vendor lock-in. No quality compromise.
ByteDance's flagship image model: native 2K & 4K output, precise layout control and reliable in-image text. Posters, product pages and campaign key visuals in one pass.
Complex camera moves and multi-character scenes stay physically coherent, with synchronized sound effects. Built for brand spots and product hero videos.
Turns one product shot into talking, moving footage: natural lip-sync, micro-expressions and handheld feel. First/last-frame control and video editing in one model.
Multi-reference generation keeps the same face across shots — built for anime, games and IP storytelling, with up to 4K output.
Shares quota and auth with the Qwen family: product images in, shoppable video out. Backed by the open-source Wan ecosystem for fine-tuning.
Natively multimodal generation: the same prompt yields keyframes or full shots — storyboards go from script to motion in a single pass.
The quality tier ships true 2K while 768p costs just $0.07/sec. Highspeed and Lite tiers cut costs on long batches — pricing is published, not negotiated.
Long bilingual copy, tables, seals and fine print land accurately. Inpainting and image editing live in the same endpoint as generation.
FRONTIER LLMS
Switch between GPT, Claude, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM and more by task and budget. One OpenAI-compatible protocol — swap models without touching business code.
SMART ROUTING
The gateway probes latency, success rate and price across providers in real time, then routes by your strategy. When a node jitters, failover is silent — your side only sees "it worked".
DEVELOPER FIRST
Point base_url at AI Station and keep everything else. Works with the OpenAI SDK, LangChain, Dify and n8n.

}'SOLUTIONS
From product imagery and short-drama storyboards to document review and compliance — vision and language meet here.
Drop in a 40-page technical report: OCR, structured extraction and standards-based verification in one pass. Out-of-range values and broken logic get flagged line by line.
Product photos in — scripts, storyboards, voiceover and finished cuts out. Seedance, Kling and H3 compete on the same brief; you pick the winner and ship it.
Packshots, lifestyle scenes, model shots and callout images from one prompt template. Selling points render directly into the pixels — no second layout pass.
Mix GPT, Claude, DeepSeek and Qwen: cheap models route, strong models reason, long-context models read. One key, one bill.
FAQ
Two lines: base_url and api_key. Model IDs come straight from the catalog. Streaming, tool calling, JSON mode and vision inputs all follow the OpenAI schema, and error codes are mapped.
Images are billed per piece, video per second, with every rate itemized in the console. For tiered models like MiniMax H3, the 768p and 2K prices are published side by side.
Yes. GPT, Claude, Gemini and Grok sit next to DeepSeek, Qwen, Kimi and GLM under the same key. Route by task: cheap models for drafts, flagships for finals — one itemized bill.
Never by default — requests are not retained or trained on, and a DPA is available. Enterprise plans add VPC access or dedicated instances with fully auditable logs.
Use the evaluation sandbox: run the same prompt and assets across models, compare outputs, latency and cost side by side, then lock the winner into your task template.
Tickets go straight to on-call engineers with a 4-hour response on business days. Enterprise plans include a dedicated TAM, 30-minute incident engagement, and SLA terms in the contract.
