Best AI playgrounds in 2025

The next generation of AI research and technology is here---and everyone is talking about it, thanks in large part to popular AI applications like ChatGPT and Stable Diffusion text-to-image generation.

Why are these AI-powered tools so popular? Partly, because they empower users to play around with the technology in an accessible way and to generate fun, thought-provoking, unique, interesting, and useful outputs.

For example, users are turning to AI to automatically generate poems from a simple text prompt, create music from text, create award-worthy artwork from text prompts, derive marketing and sales insights from large bodies of audio and text data, and much more.

If you’re looking for additional ways to play around with AI in 2025, these are the best Artificial Intelligence (AI) playgrounds and free AI tools to try. Note that background level in AI may dictate how useful some of the playgrounds are, though all should be accessible on some level to the general public.

Best AI playgrounds in 2025

OpenAI Playground

AI research and deployment company

The OpenAI playground gives users access to OpenAI’s many AI models, including GPT-3 models text-davinci-003, text-curie-001, text-babbage-001, text-ada-001, and text-davinci-002. It also includes Codex models code-davinci-002 and code-cushman-001.

Users can tweak a wide variety of parameters, including temperature, maximum length, stop sequences, frequency penalty, and presence penalty. Note that OpenAI may use the requests submitted to their models to train and improve future models. The models’ training data also does not include any data post-2021, so may lack understanding of current events.

Of course, OpenAI is also behind ChatGPT as well.

AssemblyAI Playground

Speech-to-text and Speech Understanding models to power world-class products

AssemblyAI provides industry-leading speech-to-text and speech understanding models for reliable source-truth data that power world-class products.

AssemblyAI’s AI playground lets users play around with these AI models by uploading an audio or or using one of the sample files. Then, users can choose to toggle on/off the following AI models and features:

• Transcription
• Summarization
• Topic Detection
• Auto Chapters
• Content Moderation
• Important Phrases
• Sentiment Analysis
• Entity Detection
• PII Redaction
• Speaker Labels
• Dual Channel
• Profanity Filtering

And more.

Users can also play around with LeMUR (Leveraging Large Language Models to Understand Recognized Speech) to search, summarize, ask questions, and generate new text, with knowledge of all your application’s spoken data.

Once the results are generated, users can choose to share their results with others, have the playground read back the transcription while the corresponding text is highlighted, or to test the AI models with another YouTube link or audio and video file.

New AI models are also released regularly.

NVIDIA AI Playground

Artificial Intelligence computing

NVIDIA’s AI playground lets users explore the intersection of AI, art, and science. The collection includes nine separate playgrounds and AI software, including:

• AI demo of a 360 degree immersive landscape generation, where 3D artists can use a simple web interface to customize AI art for backgrounds.
• AI art at New York’s MoMA, where a Machine Learning model interprets publicly available informational and visual data to produce the art piece, Refik Anadol: Unsupervised.
• NVIDIA Instant NeRF, an inverse rendering tool that renders 3D scenes from static 2D images in seconds.
• AI artist Vanessa Rosa’s unique digital workflow for creating ceramic humanoids.
• NVIDIA Omniverse Audio2Face, where users can automatically add emotion to 3D characters that match voice-over-tracks.
• An interactive AI-powered avatar named Violet, powered by the NVIDIA Omniverse Avatar Cloud Engine (ACE).
• Creativity and AI coffee break, where digital artists explore the creative connection between AI, history, and robots.
• LyricStudio, where users can play around with AI-generated song lyrics and poems.
• NVIDIA 3D workflow, where users can connect existing 3D workflows for live-sync creation.

HuggingFace Spaces

AI community

While not a typical AI playground, HuggingFace Spaces lets users discover impressive Machine Learning apps made by the HuggingSpace community. Users can also try out demos of various open source models such as Pixera, MaskCut, FLAN Grammar Correction, Aiornot, InstructPix2Pix, LoRA DreamBooth Training UI, Speech Recognition with visual lip movement, and FreeVC.

Most of the demo apps are implemented with Gradio, an open-source library for building easy-to-use applications using only Python.
