Nvidia Uses Proxy Models Like 'GPTOSS 2T' to Benchmark for GPT-5
nrehiew_ · x · 2026-09-01
SemiAnalysis reveals a standard practice in hardware architecture and bring-up teams:
- Proxy Models: Hardware teams like NVIDIA cannot access real weights for frontier closed models like GPT-5 or Gemini.
- GPTOSS 2T: This is a made-up model configuration created by scaling up the GPTOSS 120B architecture (layer counts, hidden dims, expert counts, etc.).
- Purpose: It serves as a stand-in for benchmarking and validating hardware capabilities against the expected scale of future models.
