Energy & Environment

The cost of
computation.
We measured it.

Most languages treat energy as someone else's problem — a datacenter concern, a cooling bill, a sustainability footnote. HexStellar treats it as a design constraint. Every watt saved is not a side effect. It is the architecture.

17.2–27.4%Less energy per card

Up to −15°CCooler, per model

+167%More capacity, same latency

100%Identical output

How this started

Found by accident.
Followed on purpose.

HexStellar wasn't the plan. It surfaced while we were building the infrastructure behind Trust Carbon Infrastructure — our other venture, a verification platform for carbon and environmental data, legally operated by Zenith Flow Innovations.

Deep in that infrastructure, we ran into a computational bottleneck that shouldn't have existed. We went after it anyway. Months of quiet investigation later, what we'd found was bigger than the problem we started with.

That side investigation became HexStellar. The numbers below are what it does today.

Hex + Stellar

HEX

Six sides. The tiling that covers a surface with the least perimeter for a given area, which is why honeycombs, basalt columns and carbon rings all settle into it. It is also how machines address themselves: hexadecimal is the base of every byte, every colour and every memory address.

STELLAR

Not a metaphor for ambition — a reference to conversion efficiency. Fusion turns mass into energy at a ratio nothing engineered has come close to. That is the standard the name points at: not how fast the work finishes, but how little is spent getting there.

Measured, not marketed

A few of the numbers.

Measured across five independent labs' flagship models on one NVIDIA H100 80GB, running vLLM — the layer on versus off, at identical load.

Capacity +167%

More capacity, one card, same latency 109.8 → 293.7 requests/sec at the same latency target — nearly three times the traffic.

Energy 17.2–27.4% Less energy per card, across five models Alibaba, Meta, DeepSeek, Google, and Microsoft's flagship models, each on identical hardware.

Thermal Up to −15°C Cooler, per model 62.4°C → 47.4°C on Meta's Llama 3.3 70B — the largest drop measured.

Reliability 100% Identical output Same answers, identical results, across every model tested — zero errors.

The complete result of that campaign, not a curated sample. A second campaign, measured per request rather than per card, is reported separately. Both are on the Proof page →

Our Position

We did not set out to build a low-energy language.

We didn't build HexStellar to be a "green" language. We built it to be the most correctly engineered language. The environmental consequence — less energy, less heat, less hardware stress — is the natural outcome of getting the foundation right.

The company behind it

Trust Carbon Infrastructure

The venture we were building when HexStellar found us — and the reason we know how to hold an engineering claim to a standard that survives scrutiny.

Digital MRV & Verification Platform · Est. 2023

Trust Carbon Infrastructure is a methodology-agnostic verification platform for carbon credit and biodiversity projects, built to work under real field conditions — offline-first data collection from a smartphone, with anti-fraud safeguards like GPS-spoofing detection and cryptographic hashing of every record. It supports major methodologies including Verra, Gold Standard, CDM and LuxCS, in 17 languages.

Over two million lines of code across the web platform and the mobile app — and almost none of it borrowed. The field app runs completely without an internet connection: no third-party APIs, no external services to call, and its own navigation system rather than a hosted map. That was not a preference. The places this platform is used do not have a signal, so anything rented from the cloud simply would not run there.

That constraint is also where HexStellar came from. Building a system that had to do everything itself, on whatever hardware was in someone's hand, is what turned a computational bottleneck into a question worth chasing.

The platform was named one of five global winners of the DPI for People and Planet Innovation Challenge, out of 540 startups from 73 countries — a $100K award, judged by the Gates Foundation, BCG and JICA. It's the same discipline — auditable, reproducible, sealed against drift — that HexStellar's benchmark numbers are held to.

Trust Carbon Infrastructure is legally operated by Zenith Flow Innovations LLC, a U.S. company based in California.
