High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.

Run, fine-tune, and deploy machine learning models with one line of code
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.
Set up a model in minutes and make an API call in Python, Node, or plain HTTP after authenticating with an API token.
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.
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.

Large consumer panel for market research surveys, but lacks Prolific's specialized focus on academic studies and AI tuning.

Faster serverless execution for image and video models, but less generalized custom model deployment than Replicate.
#3
Stronger focus on LLM inference and fine-tuning, but lacks Replicate's diverse community-curated media model catalog.
Free / Open-sourceSpecializes specifically in ultra-efficient model fine-tuning, rather than providing a general-purpose model hosting API.
Offers a broad mix of generative media models via API, but lacks Replicate's massive community deployment ecosystem.

Enterprise-grade data annotation and AI alignment workforce, but less self-serve for academic study recruitment and casual surveys.
Delivers exceptionally fast inference speeds for open models, but has a narrower model selection than Replicate.

Significantly cheaper pricing for running open-weight models, but offers fewer advanced custom training and deployment features.
