The entire inference stack exists to fix that. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/microgpt https://samitmohan.in/blog/microgpt Thu, 02 Apr 2026 00:00:00 GMT Karpathy's nanoGPT, annotated line by line. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/how-chatgpt-works https://samitmohan.in/blog/how-chatgpt-works Thu, 26 Mar 2026 00:00:00 GMT From raw internet text to a streaming response: pretraining, alignment, inference. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/attention-residuals https://samitmohan.in/blog/attention-residuals Wed, 18 Mar 2026 00:00:00 GMT The residual connection solved deep learning in 2015. Ten years later, Moonshot AI noticed it's been sabotaging deep networks the whole time. The fix is 30 lines of PyTorch. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/minitorch https://samitmohan.in/blog/minitorch Wed, 11 Mar 2026 00:00:00 GMT Building PyTorch from scratch in ~1300 lines - reverse-mode autograd, conv2d, optimizers. Trains MNIST. No C++, no CUDA, just closures and NumPy. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/interview-questions https://samitmohan.in/blog/interview-questions Fri, 13 Feb 2026 00:00:00 GMT Five questions I actually ask ML candidates. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/rag https://samitmohan.in/blog/rag Tue, 27 Jan 2026 00:00:00 GMT My blogs are too long so I built a RAG over them. Chunking, FAISS, reranking, streaming via Groq - and an eval pipeline because vibes aren't metrics. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/math https://samitmohan.in/blog/math Wed, 21 Jan 2026 00:00:00 GMT The math behind deep learning, with code for every concept. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/torch https://samitmohan.in/blog/torch Wed, 07 Jan 2026 00:00:00 GMT Ground-up NumPy and PyTorch - we build MNIST classifiers two ways to see how the pieces fit together. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/paper https://samitmohan.in/blog/paper Tue, 06 Jan 2026 00:00:00 GMT Taking DeepSeekV3 apart: MLA, MoE routing, multi-token prediction. And how to read a 53-page paper. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/scalinglaws https://samitmohan.in/blog/scalinglaws Tue, 06 Jan 2026 00:00:00 GMT Maybe intelligence is just a lot of compute applied to a lot of data having a lot of parameters. OpenAI wrote a paper on this. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/yolo https://samitmohan.in/blog/yolo Fri, 21 Nov 2025 00:00:00 GMT The full YOLO story from v1 to v10 - grid system, loss function, NMS, mAP, and a PyTorch implementation. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/mcp https://samitmohan.in/blog/mcp Sat, 25 Oct 2025 00:00:00 GMT I built an MCP server so Claude can control my Spotify. samitmohan@gmail.com (Samit Mohan) https://samitmohan.in/blog/nn https://samitmohan.in/blog/nn Sat, 25 Oct 2025 00:00:00 GMT Neural nets from scratch.
