Silicon economics

What it costs to put
an open accelerator on silicon.

Openness only matters if the design can actually be built. These are the concrete, presently-available fabrication paths — not a vague "coming soon".

IHP Germany

Free

A free research shuttle route for open-source projects. Removes the single biggest cost barrier to a first physical test chip — the recommended starting point.

Costs are the figures published in the T1C repository. They are planning estimates for shuttle and MPW access, not validated production-cost figures — T1C has not been fabricated yet.

Against commercial silicon

A few hundred dollars
instead of tens of thousands.

The comparison that matters is not tokens per second. It is whether an independent engineer or a university lab can afford to put the design on real silicon at all.

Figures are architectural projections from the T1C repository, not measured silicon benchmarks. T1C is not faster than an H100 and does not claim to be.

The most valuable feedback
arrives before tape-out.

That is why the project is open now rather than later — while the architecture is still cheap to change.
