Developers wanting access to hundreds of AI models without juggling multiple API keys need something different than ChatGPT's single-model approach. APIMart gives you 500-plus models through one endpoint.
OpenAI compatibility is what sells it. Change one line of code (the base URL) and you're running Claude, Gemini, DeepSeek, or any of the other 100-plus language models available. No SDK rewrite needed. Your existing implementation stays intact. A startup engineer testing different models for a chatbot can switch between GPT-5 and Claude Sonnet 4.5 without touching application logic.
APIMart includes video generation beyond chat models—Sora 2 and Veo 3.1 specifically. Image APIs like Flux.1 and Seedream 4.5 are available too. You'll save 30 to 70 percent on costs compared to going direct or using Fal.ai and Replicate. Pricing runs from $0.008 per request for basic image generation up to $1 for Sora 2 Pro. A free tier lets you test things before committing money.
Smart routing picks the fastest endpoint automatically. Global latency stays under 50 milliseconds. Streaming works here. Function calling works. Vision capabilities work—all the same way OpenAI handles them.
Consolidation is the real appeal. Instead of managing accounts and billing across five different AI providers, you get one API key and one invoice. For teams building multi-model applications, that alone might justify switching. The tradeoff? You're adding another middleman between your app and actual model providers. Some teams won't love that.
