Open-source engineering calculators for civil and structural design
Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub.
Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.
Registered users get calculation workings, bending/shear/deflection diagrams and PDF export.
Four project-based pathways in Python, AI for construction, AI governance and building AI agents.

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.
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.
Free / Open-sourceSearch and study millions of public SKILL.md agent skills

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

Provides affordable serverless GPU execution and diverse model APIs, but with a less polished developer ecosystem.
Free / Open-sourceFree practical deep learning courses, research and open-source libraries

Free / Open-sourceServerless, decentralized inference for open-source AI models
