## ModelsLab

ModelsLab is an API-first platform for teams that need many kinds of generative AI without managing many vendors. It aggregates more than 10,000 models spanning text-to-image, image editing and inpainting, upscaling, text-to-video and image-to-video, text-to-speech, voice cloning, music and sound effects, 3D generation, and chat or reasoning LLMs. All of these sit behind one API key and a unified JSON schema, so an app can start with one model and scale to others without changing its integration.

The typical workflow is browse, test, then build. You search the model library by task, try prompts in a playground to compare outputs, and once a model fits, you call it from your application with a single REST key or through the provided SDKs, CLI, and MCP server. That agent-friendly design means tools such as Cursor, Claude Desktop, Windsurf, or VS Code can invoke image, video, voice, and reasoning tools directly. Production features include request-by-request logging, webhooks for long-running jobs, and reported 99.9% uptime.

Beyond calling hosted models, ModelsLab lets you train your own models on its GPUs, run open-source models unlimited on shared capacity, or reserve a dedicated GPU for consistent throughput. Pricing starts at $21 per month with an unlimited open-source tier from $149 per month, and dedicated GPUs from $249 per month, making it a fit for startups prototyping as well as teams shipping AI features at scale.

**Pricing & Plans:** Free tier available; standard plans start at $21 per month, unlimited open-source generation runs from $149 per month, and dedicated GPUs start at $249 per month. Enterprise and custom training options are available on request.

- **10,000+ models, one API:** Access image, video, audio, 3D, and text models through one API key and a unified JSON schema, instead of juggling multiple vendors.
- **Playground and comparison:** Browse 10,000+ models by task, compare outputs, test prompts in a playground, then call the model from your app with the same integration.
- **Shared or dedicated GPUs:** Run open-source models on shared infrastructure, or reserve a dedicated GPU for predictable throughput and unlimited generations.
- **Model training:** Train fine-tunes on platform GPUs, clone voices, and customize models to fit specific products, brands, or styles.
- **MCP, SDK, and CLI:** Connect via a Model Context Protocol server, type-safe SDKs, or a CLI so AI editors and agents can call generation tools without glue code.
- **Request logging and webhooks:** Track every request with status and latency, and receive webhooks when longer video or audio jobs finish.

**Strengths:** One API key and unified schema across image, video, audio, 3D, and LLM models; Large 10,000+ model catalog with a playground for comparing outputs before you code; MCP server, SDKs, and CLI make it easy to plug into AI coding agents and automation

## Stable Diffusion API

Stable Diffusion API gives developers a single HTTP endpoint for the whole Stable Diffusion family and a long list of community checkpoints. Instead of provisioning GPUs, installing PyTorch, and keeping model weights in sync, you send a POST request with a prompt, model id and parameters, and receive generated images plus a track id you can poll or receive via webhook. The catalog the site advertises covers SD 1.5, SDXL, Stable Diffusion 3, FLUX.1 dev/Schnell, FLUX.2 dev, Qwen Image, Z-Image Turbo, video models such as Wan 2.2 and LTX Video, and dedicated families like Realistic Vision, Juggernaut XL, Pony Diffusion, DreamShaper and Illustrious XL.

Beyond plain text-to-image, the API exposes image-to-image, inpainting, upscaling, background removal, ControlNet conditioning, LoRA usage and Dreambooth-style model fine-tuning, so a single integration can cover asset generation, product mockups, advertising variants and interior or fashion visuals. Official code samples for cURL, Python and Node are published for each model page, which shortens the time from signup to a first working request.

The platform is now presented as part of ModelsLab: accounts, API keys and billing live in the ModelsLab dashboard, and the site states that API requests are processed at scale with a 99.99% uptime target. Pricing is transparent and outlined on the site, with plans starting at $21 per month and an unlimited open-source tier for high-volume workloads.

**Pricing & Plans:** Paid plans billed through ModelsLab: Basic $21/month (3,250 API calls, 5 parallel generations), Standard $47/month (10,000 calls, 10 parallel generations), and Open Source Unlimited $149/month or $1,500/year (unlimited generations on self-hosted open-source models, 15 parallel generations). Third-party and closed models are billed separately; Enterprise offers dedicated GPUs and custom SLAs. Creating an account is free, but API access requires a paid plan.

- **Unified REST endpoint:** One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
- **Large community model catalog:** Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
- **Async jobs and webhooks:** Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
- **Fine-tuning and training:** Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
- **Scaling controls and enterprise options:** Parallel generation limits grow by plan, and an enterprise tier provides dedicated GPUs with custom SLAs for high-volume production traffic.

**Strengths:** Single API surface for many base models and thousands of community checkpoints; No GPU provisioning, driver or model-weight maintenance on your side; Publishing-ready code samples for cURL, Python and Node per model; Transparent tiered pricing with an unlimited open-source plan and enterprise GPUs

**Limitations:** API access requires a paid subscription; the free account only unlocks the dashboard; Third-party and closed models are billed separately from the unlimited open-source plan; Call quotas are counted per request, so batch-heavy experiments can consume a plan quickly
