APIMODELS is a unified AI model API that puts 100+ image, video, music, speech and LLM models behind one endpoint, one API key and one balance. Instead of opening an account with OpenAI, Google, Anthropic, ByteDance, Suno, ElevenLabs, MiniMax, xAI, DeepSeek, Alibaba and Zhipu separately — each with its own SDK, billing and approval process — you sign up once and switch models by changing a single string. Flagship image models, priced per image with no token math: • Nano Banana Pro (gemini-3-pro-image-preview) — $0.06 at 1K and 2K, $0.12 at 4K. Google lists the same model at $0.134 and $0.24, so that is 55% and 50% below list. Our $0.06 is also lower than Google's own Batch API price of $0.067 — and Batch makes you queue, while we return in real time. • Nano Banana 2 (gemini-3.1-flash-image-preview) — $0.05 at 1K and 2K, $0.08 at 4K, against Google's $0.067 / $0.101 / $0.151. That is 25% off at 1K, 50% off at 2K and 47% off at 4K. • GPT Image 2 (gpt-image-2) — a flat $0.025 per 1K image, $0.04 at 2K, $0.06 at 4K, with up to 16 reference images for multi-image editing. OpenAI bills this model by token; we bill a fixed price per image, and no OpenAI organization verification is required. The API is OpenAI-compatible, so existing SDKs, Cursor, Codex and LangChain code work by pointing base_url at apimodels.app. Billing is strictly pay-as-you-go with per-call prices published on every model page, starting at $0.001; there is no subscription, no monthly minimum and no expiring credits, and failed generations are never charged. New accounts get $0.10 of free credit with no card required.
