Open-Source AI Accelerator Architecture. Like RISC-V did for CPUs, T1C does for AI chips.
"We Design It. World Builds It."
| Problem With Current AI Chips | T1C Solution |
|---|---|
| NVIDIA H100 costs $30,000 | T1C blade costs $280–$650 |
| Closed source — can't modify | Fully open source — MIT license |
| Need special cleanroom | Fabricatable via community shuttles |
| Von Neumann bottleneck | D-IMC — compute inside memory |
| No hardware multi-tenancy (cheap) | MIM — 4 isolated tenants per chip |
| System | LLaMA 7B Speed | Max Model | Cost | Open Source |
|---|---|---|---|---|
| T1C — 1 Blade | 12–20 tok/s | ~64B INT4 | $280–$650 | ✅ MIT License |
| T1C — 8 Blades | 96–160 tok/s | ~512B INT4 | $2,240–$5,200 | ✅ MIT License |
| NVIDIA RTX 4090 | 80–100 tok/s | ~24B FP16 | $1,500 | ❌ Closed |
| NVIDIA H100 | 1000+ tok/s | Unlimited | $30,000 | ❌ Closed |
Note: T1C is not faster than H100. T1C's value is: open source + DIY buildable + hardware tenant isolation + Indian-designed.
