ModelsLab is a developer API platform that unifies 10,000+ open-source and closed-source AI models for image, video, audio, 3D, and LLM generation behind one API.
About
ModelsLab is a paid API platform that gives developers access to a large catalog of AI generation models — more than 10,000 across image, video, audio, 3D, and language tasks — through a single unified API. It addresses a common developer pain point: instead of integrating and paying separately for a dozen model providers, a team can switch between models by changing one model_id parameter while keeping the same integration.
The platform hosts both open-source models (such as Flux, SDXL, Qwen, and WAN on its own GPU infrastructure) and closed-source third-party models (such as Google's Nano Banana 2.1, ElevenLabs' Eleven v4, Ideogram 4.5, and Kling). Beyond raw APIs, ModelsLab publishes a CLI, SDKs, an MCP server, OAuth-based agent authentication, and an agent control plane, so AI agents can sign up, generate API keys, and run generations without a browser. The company reports 400,000+ registered users, 500 million+ processed API requests, and about 500 GPUs in its own datacenter.
Key Features
Pricing & Fees
- Pricing: Three subscription tiers are listed: Basic at $21/month (3,250 API calls, 5 concurrent requests, shared GPU), Standard at $47/month (10 concurrent requests, priority support), and Open Source Unlimited at $149/month (unlimited generations on open-source models, 15 parallel requests, 24/7 support). Yearly billing includes two months free, and all plans carry a 100% refund policy with cancellation at any time.
- No free tier: ModelsLab is paid-only; there is no free plan, trial, or free credits. Each model page shows example outputs and sample request bodies for evaluation before subscribing.
- Wallet for premium models: Closed-source third-party models are billed separately through a wallet top-up available only to active subscribers; the $149 plan covers open-source generations only.
- Usage resets monthly: Plan allowances reset each billing period and unused allowance does not roll over.
Who It's For
ModelsLab is aimed primarily at developers and engineering teams building AI-powered products who want one integration instead of many provider accounts. Typical users include startup teams prototyping image or video features, agencies building creative tools, and platform engineers running production workloads that need predictable concurrency limits and support. It also targets a newer audience: builders of AI agents, who can use the MCP server, CLI, and scoped OAuth tokens to let autonomous agents call generation APIs directly. Anyone needing to compare or A/B test many models — for example swapping text-to-image backends — benefits from the single model_id switching design.
FAQ
What is ModelsLab?ModelsLab is a paid API platform that provides access to 10,000+ open-source and closed-source AI models for image, video, audio, 3D, and LLM generation through one unified API.
Does ModelsLab have a free plan or trial?No. The service is subscription-only with plans starting at $21/month, though every monthly and yearly plan carries a 100% refund policy and can be cancelled at any time.
What developer tools does ModelsLab provide?It offers API documentation, SDKs, a CLI (modelslab.sh), an MCP server, webhooks, OAuth scoped authentication, an agent control plane, and markdown/text access to pages for AI agents.
How does it compare to using fal.ai or Replicate?ModelsLab positions itself as a single replacement for multiple API providers and publishes direct comparisons with fal.ai and Replicate on its pricing page for developers switching providers.
What happens with unused API calls at the end of the month?Plan allowances reset at the start of each billing period and do not roll over; wallet balances for premium third-party models are handled separately from plan allowances.
