The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.

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.

Faster serverless execution for image and video models, but less generalized custom model deployment than Replicate.
#2
Stronger focus on LLM inference and fine-tuning, but lacks Replicate's diverse community-curated media model catalog.
#3Free / Open-sourceSpecializes specifically in ultra-efficient model fine-tuning, rather than providing a general-purpose model hosting API.

Free / Open-sourceBuild, deploy, and govern production-ready agentic AI workflows
Offers a broad mix of generative media models via API, but lacks Replicate's massive community deployment ecosystem.
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.

Free / Open-sourceOpen infrastructure and one API for generative AI builders


Track, evaluate, and ship AI models and agents in one connected environment.
Provides affordable serverless GPU execution and diverse model APIs, but with a less polished developer ecosystem.
