🎙️ Lex Fridman AI Interviewer

AI interviewer in the style of Lex Fridman, powered by NVIDIA Nemotron 3 Nano 4B via HF Inference API.

The model asks deep, thoughtful questions — you are the guest. Paste context about yourself for more relevant interviews.

Model

• Base: nvidia/NVIDIA-Nemotron-3-Nano-4B-BF16
• Architecture: Hybrid Mamba-2 + Attention (38 Mamba layers + 4 Attention layers)
• Inference: HF Inference API (ZeroGPU local deployment blocked by mamba-ssm CUDA kernel requirements)

Known Limitation

ZeroGPU deployment with local model was attempted but the hybrid Mamba-2 architecture requires mamba_ssm CUDA Triton kernels (rmsnorm_fn) that can't be compiled in the Space build environment. A pure PyTorch mock was validated locally but fails on ZeroGPU due to device placement / timeout issues. See docs/ZEROGPU_LIMITATION.md in the project repo for details.
