- OAuth (Open Auth)
- An open standard authentication protocol that lets third-party apps access a user's account without sharing passwords — here, used to tap a paid AI subscription outside its intended platform.
- Pre-training
- The initial, large-scale phase of training an AI model on massive datasets before any fine-tuning or specialisation; likened in the episode to going to school before an exam.
- Post-training
- Fine-tuning steps applied after pre-training — including RLHF and instruction-tuning — to align a model's behaviour; compared to coaching after school.
- RLHF
- Reinforcement Learning from Human Feedback: a technique for fine-tuning AI models by rewarding outputs rated positively by human evaluators.
- Effective Altruism (EA)
- A philosophy that uses evidence and reasoning to determine the most impactful ways to benefit others — central to Anthropic's founding culture and funding network.
- Open Philanthropy
- A major EA-aligned philanthropic fund co-founded by Dustin Moskovitz; one of Anthropic's earliest and largest backers.
- Claude Constitution
- Anthropic's published set of principles that govern Claude's behaviour — a strict guideline the model is not supposed to deviate from, closely tied to EA philosophy.
- Claude Code (OpenCLO / OpenClaw)
- Anthropic's agentic coding assistant that operates in terminals and IDEs; also used in the episode to refer to the broader open-source framework for routing AI tasks.
- Vibe coding
- A colloquial term for rapidly prototyping software by prompting AI models iteratively, relying on the AI to write most of the code.
- Distillation
- A technique where a smaller 'student' model is trained to mimic the outputs of a larger 'teacher' model, making open-source models competitive by learning from frontier closed-source ones.
- Agentic AI
- AI systems that can autonomously plan, take actions, and call tools over multiple steps to complete complex tasks without constant human prompting.
- VPS (Virtual Private Server)
- A virtualised cloud server that acts like a dedicated machine, giving users more control over their data than shared hosting or consumer AI apps.
- ARR (Annual Recurring Revenue)
- A standardised metric for subscription businesses representing the annualised value of recurring revenue — used here to gauge Higgs Field's growth trajectory.
- ASIC
- Application-Specific Integrated Circuit: a chip designed for one specific task; here used loosely to refer to specialised AI accelerators in the cloud.
- TPU
- Tensor Processing Unit: Google's custom AI chip, giving Google a full-stack hardware advantage over Anthropic and OpenAI who rely on third-party silicon.
- OSWorld
- A benchmark that tests an AI agent's ability to navigate and operate a real computer desktop — GPT-5.4 reportedly surpassed the human baseline on this test.
- Moore's Law
- The observation that the number of transistors on a chip doubles roughly every two years, roughly halving cost — invoked here to frame the 850x drop in AI token prices.
- FUD
- Fear, Uncertainty, and Doubt: negative sentiment or disinformation spread about a product or company, often to damage reputation or suppress adoption.
- Loss leader
- A product sold below cost to attract customers and gain market share, with the expectation of profiting later — applied here to AI subscription pricing.
- Quant (QUANT model)
- A quantised version of a large language model compressed to run on consumer hardware with reduced memory requirements, at some cost to output quality.
