The case

Why GreenPT.

We built GreenPT for people who care where their AI runs and what it costs the planet. Three structural choices make the difference.

  • Sustainable hosting: 100% renewable energy, verified, no offset accounting

  • Efficient model selection: quantised open-source models with a fraction of the energy footprint

  • Technical optimizations: every layer of the stack tuned for lower PUE and WUE

  • Inputs are never used for model training, on any plan

  • Pricing in euros from day one
