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.

One API for 1,500+ production-ready generative media models
Over 1,500 image, video, audio, 3D, and world models behind one API key, with new models added as they launch.
A custom inference stack that fal claims is up to 10x faster for diffusion models, designed for latency-sensitive production traffic.
Deploy your own or fine-tuned models, including private LoRAs and custom endpoints, with autoscaling and observability built in.
Multi-node clusters of H100, H200, B200, and B300 GPUs for training and fine-tuning compute-intensive workloads.

Extremely cost-effective serverless inference for open-weight models, but lacks fal.ai's deep specialization in real-time media pipelines.
Consolidates image, video, and audio models under single endpoints, but lacks fal.ai's advanced custom weight deployment.

Faster high-volume generative image inference, but offers a more specialized media feature set than fal.ai.
