# API Models

> API Models (apimodels.app) is an AI model aggregation API that lets developers call image, video, audio, and LLM models from many providers through one unified API and a single balance — usually cheaper than going direct, and usable from China and worldwide.

## Key Pages

- [Models](https://apimodels.app/en/models): Browse 113 image / video / audio / LLM models, each with pricing and a one-line API call.
- [Pricing](https://apimodels.app/en/pricing): Per-call and per-token pricing for every model.
- [Docs](https://apimodels.app/en/docs): API reference, code samples (cURL / Python / Node), and CLI integration guides (OpenAI Codex, Claude Code).
- [Unified API](https://apimodels.app/en/unified-api): One key and one endpoint for image, video, and LLM models.

## Key Facts

## Newest Models

OpenAI's GPT-5.6 family, callable on both /api/v1/chat/completions and /api/v1/responses. Prices are USD per 1M tokens; reasoning tokens count as output. Reasoning depth is a model-name suffix (-low / -medium / -high / -xhigh / -max / -ultra), all at the same price. Requests with more than 272,000 input tokens are billed at 2x input / 1.5x output.

- [GPT-5.6 Sol](https://apimodels.app/en/models/gpt-5-6-sol): frontier tier. $1.103 input / $6.618 output / $0.110 cached input. The `gpt-5.6` alias routes here. About 78% below OpenAI's own $5 / $30 list.
- [GPT-5.6 Terra](https://apimodels.app/en/models/gpt-5-6-terra): balanced mini tier, exactly half of Sol. $0.551 input / $3.309 output / $0.055 cached input.
- [GPT-5.6 Luna](https://apimodels.app/en/models/gpt-5-6-luna): cheapest nano tier for high-volume work, 20% of Sol. $0.221 input / $1.324 output / $0.022 cached input. Call it as `gpt-5.6-luna-max`.

xAI's newest generation, both added 2026-08-14. Figures below are measured against the live channel, not copied from launch posts.

- [Grok 4.6](https://apimodels.app/en/models/grok-4.6): xAI's frontier LLM, built for long-running agents and multi-step work. Model id `grok-4.6` on /api/v1/chat/completions (OpenAI-compatible). $1.765 input / $5.294 output per 1M tokens / $0.441 cached input — 12% below xAI's own $2 / $6. 500K context, text and image input, four reasoning-effort levels (low / medium / high / xhigh), default is high. Two things worth knowing: billed output tokens include reasoning tokens, and the default effort measures ~53s, so set client timeouts above 60s. Live web search works on /api/v1/responses, not on /chat/completions.
- [Grok Imagine Image 2.0](https://apimodels.app/en/models/grok-imagine-image-2): xAI's newest image model, model id `grok-imagine-image-2.0` on /api/v1/images/generations. Priced by resolution × quality: 1K low $0.03, 2K low $0.04, 1K medium $0.045, 2K medium $0.06 per image — all four 25% below xAI list, and 2K low 33% below. `quality` takes low or medium and defaults to medium. Fuses up to 3 reference images in one call (a 4th is refused explicitly, not dropped silently) and reference images cost nothing extra. 14 aspect ratios including ultra-wide 19.5:9, 9:19.5, 20:9 and 9:20. Strong at in-image typography — an exact headline, date line and small-print URL all came back character-correct on a 2K poster. Two verified limits: editing re-renders the frame rather than editing pixels in place, so crop and camera angle shift between passes; and it cannot produce transparent backgrounds — asked for alpha it paints the checkerboard as ordinary pixels and returns an RGB PNG.
