AI/ML API
Officially listedUnified API gateway giving access to 400+ AI models through a single key.
AI/ML API
AI/ML API is a unified AI model API gateway: a single endpoint accesses 400+ AI models from top providers including OpenAI, Anthropic, Google, and Meta. One API key covers chat, image, video, audio, and 3D across all modalities, with no need to apply to multiple providers or manage multiple bills — the first choice for developers and startup teams seeking efficient integration.
Core Capabilities
- 400+ Models in One Place: Global mainstream LLMs and multimodal models, all called with one key, usage-based billing with no monthly fee
- Fully OpenAI-Compatible: Change only the base_url and existing OpenAI projects migrate at zero cost within 5 minutes
- Full Multimodal Coverage: Chat/Image/Video/Audio/3D/OCR/embeddings all supported, while competitor OpenRouter is limited to LLM text
- AI Playground Sandbox: Test 300+ models instantly in the browser and evaluate options without writing code
- Cryptocurrency Payments: Supports developers in emerging markets, credits never expire, and flexible top-ups start at $20 prepaid
- Complete Developer Ecosystem: Official docs, API Academy tutorials, and Discord community support across channels
Use Cases Independent developers validating multi-model prototypes quickly, startup teams integrating full-modality AI without juggling multiple accounts, and engineers comparing models side by side. A first choice for low-risk, non-critical workloads; not suitable for enterprise production systems with extremely high stability requirements.
Unique Advantages One-stop multimodal coverage is the core differentiator: OpenRouter supports only LLM text and Together AI leans LLM, while AI/ML API supports Chat/Image/Video/Audio/3D simultaneously. Aggregated pricing runs up to 80% cheaper than calling OpenAI directly, and crypto payments are a feature no mainstream competitor offers.
Editor's Review G2 rates it 4.7/5, and professional media consistently praise its integration convenience and model breadth. But Trustpilot sits at only 2.7/5, with billing disputes and poor support response as clear weaknesses. Individual developers should test with small amounts first; value is high for PoC and prototyping, while enterprise production should rely on it only after fully validating stability and billing accuracy.

FAQ
Is AI/ML API free?
There is a free trial allowance. Regular use follows a freemium model with a pay-as-you-go option prepaid from $20, billed by actual usage, and credits never expire.
What are AI/ML API's main features?
Access 400+ AI models through a single API key, covering chat, image generation, video generation, speech synthesis, 3D modeling, and more — fully compatible with the OpenAI protocol.
Which AI models does AI/ML API support?
It supports mainstream LLMs such as GPT-5.5, Claude Opus 4.7, Gemini 3 Flash, DeepSeek R1, and Qwen3, plus video generation models like Sora 2 and Veo 3.1 — 400+ in total.
What is the difference between AI/ML API and OpenRouter?
AI/ML API covers all modalities — Chat/Image/Video/Audio/3D — while OpenRouter supports only LLM text. AI/ML API also accepts cryptocurrency payments, which OpenRouter does not.
Is AI/ML API suitable for enterprise production environments?
Suitable for individual developers and small startups; enterprises should be cautious — a 2.7/5 Trustpilot score, stability issues, and billing disputes mean thorough testing before relying on it.
How do I migrate to AI/ML API from OpenAI?
Just change the base_url in your code to https://api.aimlapi.com/v1 and nothing else changes; existing OpenAI SDK projects migrate in about 5 minutes.
