Paper notes on Llama 2 covering its commercial license, a base model scaled to 2T tokens with 4k context and GQA, and the Llama 2-Chat alignment pipeline (SFT → two reward models → iterative RLHF with rejection sampling + PPO → GAtt). It fuses LLaMA's open base lineage with InstructGPT's RLHF at production quality.
Floci is an always-free, open-source local AWS emulator with no account, no auth token, and no feature gates. A single Quarkus + GraalVM native container emulates 68 AWS services behind one port, 4566. We analyze its Smithy-spec protocol routing, descriptor-driven service catalog, four storage modes, and real Docker execution — against LocalStack.
Paper notes on LLaMA covering its core strategy — train smaller models for longer on publicly available data, optimized for inference — the result where a 13B model beats 175B GPT-3, the RMSNorm/SwiGLU/RoPE architecture changes, the 2048-A100 training scale, and how it kicked off the open LLM ecosystem.
Firecrawl is a data API that turns any website into clean, LLM-ready Markdown or structured JSON. It orchestrates in TypeScript, cleans in Rust, converts to Markdown in Go, races several scrape engines in a waterfall, and drives crawls with a hand-built Postgres queue. We analyze the scrape/crawl/map/search/extract pipelines and contrast them with Browser Use as "two ways to feed the web to LLMs."
SkillSpector is NVIDIA's security scanner for AI agent skills. It vets a skill before install to find prompt injection, data exfiltration, and malicious code. We analyze its structure — a LangGraph map-reduce graph that fans out to 25 analyzers (static patterns, AST, taint, YARA, MCP, LLM semantics) and reduces them to a single risk score — against Superpowers and ponytail, which inject skills.
