Notes from the trenches on AI engineering, LLM apps, and the full-stack work that holds it all together.
The open-source Hiring Agent pipeline parses PDFs to JSON Resume, enriches with GitHub repo metrics, and scores candidates with role-specific rubrics. Here is the architecture and where I would add guardrails.
Business Insider reports Hugging Face is exploring a sale at $13 billion or more, nearly 3x its 2023 valuation, weeks after Stripe agreed to buy OpenRouter for about $8 billion.
The Kimi-K2.6-519B-NVFP4 checkpoint prunes MoE experts with Cerebras REAP rules. It is strong on code, math, and tool calls, but you must keep outputs bounded to avoid repetition loops.
Meituan's LongCat-Video-Avatar 1.5 turns one image plus one voice clip into lip-synced avatar video with 8-step distillation inference. Here is the hardware honest breakdown and when fal.ai beats self-hosting.
Loop engineering is designing verifiable agent cycles instead of hand-editing prompts. Here is the maker-checker pattern, when loops earn their token cost, and how SkillOpt-style optimizers fit in.
MIT's World-Space Interface lets operators mimic digging motions with a small arm-and-bucket controller instead of joysticks. First-time users finished basic tasks 37% faster and matched experts from week one.
Cosmos 3 Super Text2Image is a 64B open omnimodal model tuned for physically plausible images. Here is how Diffusers, vLLM-Omni, and agentic upsampling fit into a real synthetic-data pipeline.
llama-nemotron-embed-1b-v2 ships Matryoshka 2048-dim vectors, 26-language eval coverage, and commercial-friendly NeMo Retriever licensing for long-document QA retrieval.
