## AI Grant

AI Grant is a grant-giving initiative focused on the open source side of artificial intelligence. Rather than investing in companies for equity, it hands out individual awards between $5,000 and $50,000 to people building freely available tools, datasets, libraries and research artifacts. Funding can arrive as cash, as compute credits, or as a mix of the two, depending on what the recipient needs most.

Over the years the program has supported a wide range of work: a Python binding for the llama.cpp inference engine, the GGUF model file format that became a de facto standard for local model distribution, fast cross-platform deep learning libraries for the browser, datasets for sound event research, tools for simulating quantum systems and gravitational lensing, medical imaging work such as stroke scan interpretation and child abuse detection in X-rays, and many smaller research and infrastructure efforts. This breadth reflects the program's interest in useful, reusable building blocks rather than a single vertical.

AI Grant was founded in 2017 by Nat Friedman and Daniel Gross. Note that aigrant.org handles the grant program for open source projects, while the founders' separate accelerator for AI startups lives at aigrant.com. AI Grant operates as an independent organization and is not affiliated with OpenAI, Google or any other model provider named in project descriptions.

**Pricing & Plans:** Not a paid product. AI Grant awards $5,000 to $50,000 per project in cash or compute credits, with no equity and no obligations attached to the funding.

- **Cash or compute awards:** Grants range from $5,000 to $50,000 and can be paid out as money, compute credits, or a combination of both.
- **Open source focus:** Funding targets openly licensed libraries, datasets, formats, research tools and infrastructure that others can build on.
- **No equity, no strings:** Recipients keep full ownership of their work; the program does not take equity or impose commercial obligations.
- **Broad technical scope:** Past grants span inference engines, model formats, browser deep learning, medical imaging, art generation and quantum simulation.
- **Published recipient list:** The site lists current and prior grants with links to papers, videos and repositories so progress is publicly visible.

**Strengths:** Awards carry no equity requirement or commercial obligations; Funding can be taken as compute when that is more useful than cash; Public recipient list with links to papers, videos and repositories; Supports a broad range of open source AI infrastructure and research

**Limitations:** No published application form or eligibility checklist on the site; Award amounts are modest compared with venture funding for larger teams; Grant timelines and selection criteria are not documented publicly

## CalcForge

CalcForge is a community-built engineering platform that combines a large library of free, open-source calculators with professional training pathways for civil and structural engineers. The toolkit spans structural analysis (beam, frame, truss, steel and concrete section design), geotechnical work (bearing capacity, slope stability, retaining walls, foundation settlement), tunnelling, and contractor tools such as formwork, scaffolding and slope grading. It also ships curated construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.

The free tier gives registered users full calculation workings, bending/shear/deflection diagrams and PDF export, while the one-time Lifetime All-Access pass unlocks advanced calculators, code templates and enrolment in four training qualifications. The project grew out of Civils.ai and is supported by an active Discord community of around 1,500 engineers across 30+ countries.

Because the tools are open source on GitHub, engineers can fork the code, add their own calculators and send pull requests back to the main project. CalcForge positions itself as a way to democratise engineering knowledge and to help professionals automate the most time-consuming parts of their work.

**Pricing & Plans:** Free account with core engineering tools and datasets; one-time Lifetime All-Access payment unlocks 32+ advanced calculators, 10,000+ construction datasets, code repositories and four training qualifications.

- **50+ open-source calculators:** Structural, geotechnical, tunnelling and contractor tools available free and open source on GitHub.
- **Datasets for benchmarking:** Searchable construction datasets covering high-rise buildings, bridges, tunnels, dams and housing.
- **Full workings and diagrams:** Registered users get calculation workings, bending/shear/deflection diagrams and PDF export.
- **Professional certifications:** Four project-based pathways in Python, AI for construction, AI governance and building AI agents.
- **Community collaboration:** A Discord community of 1,500+ engineers sharing calculators, ideas and contributions.

**Strengths:** Genuinely free and open source for the core calculator library; Broad coverage from structural analysis to tunnelling and contractor tools; Rare combination of tooling plus structured training certifications; Active community and transparent GitHub contributions

**Limitations:** Advanced calculators and datasets sit behind the paid lifetime pass; Code snippets and some datasets are not available on the free tier; Advanced training materials are geared to construction rather than general software fields
