它们的增长率如何比较？

Replicate AI 的月度环比增长率为 -8.4%；UserAPI.ai 为 +1.6%。

价格如何比较？

Replicate AI: 付费。Paid, usage-based — you only pay for what you use. Most public models are billed by runtime at per-second hardware rates; some models are billed per input and output (for example, $0.04 per output image on Flux 1.1 Pro, $3.75 per million input tokens on DeepSeek R1). Published GPU hardware ranges from about $0.81/hr for a T4 up to roughly $43.92/hr for 8x H100. Private deployments bill for setup, idle, and active time on dedicated hardware, and you can start for free. Enterprise and volume discounts available. UserAPI.ai: 免费增值，付费。UserAPI.ai 提供 50 次请求的免费包，无需信用卡。使用你自己的 Midjourney 账户时，每次请求 0.04 美元或每月 25 美元（或每季度 67.50 美元、每年 246 美元）；UserAPI Cloud 在 UserAPI 的账户上运行，每张图 0.08 美元，相比 0.20 美元的首发价打 6 折，3 美元起（约 37 张图），失败任务自动退款。

Replicate AI

Replicate is a cloud API for running, fine-tuning, and deploying machine learning models. Spin up open-source and hosted models — from image, video, and audio generation to speech synthesis, captioning, and LLM inference — with one line of code, or package your own model with Cog and put it behind a production-ready API.

Thousands of models behind one API

Run image, video, audio, speech, and language models through a uniform API surface, with official models for FLUX, Nano Banana, Seedream, Grok Imagine, MiniMax, Wan, Seedance, and more.

One-line-of-code inference

Set up a model in minutes and make an API call in Python, Node, or plain HTTP after authenticating with an API token.

Cog packaging and custom deployments

Package your own model with Cog, an open-source tool for packaging machine learning models, and deploy it on dedicated hardware that scales up and down with demand.

Model fine-tuning

Fine-tune models on your own data, including fast-booting fine-tunes that are billed only while actively processing requests rather than for idle time.
