Category: AI
You are here if AI showed up in your job and the names on the screen do not match the buttons. This category is practical. It is not a model-release calendar, and it is not one lesson pasted under a new product name. The series split the pile so a Claude post and a ChatGPT post can teach different work.
Everyday paths are for a person with no account yet, or a person whose chat forgot a file: setup, prompting, memory, agents, safety, and which product fits a job. Product paths stay on one tool: Claude, ChatGPT, Gemini, or Grok, from a first login to the surface you should not open. Open-weight paths are Llama, DeepSeek, Qwen, Kimi, and GLM: what the name refers to, and when a normal paid chat is the easier tool. Engineering paths are for running a model, retrieving from your own files, and fine-tuning. Several of those hubs are still waiting on a first live part, and the hub page says so.
Where to start: no account yet, use AI setup from zero. You already pay for one product, open that product’s series and use the first part. You want the idea before the brand, use Practical AI. You want every series in order, use Learn and the AI tracks.

How to share a Custom GPT with your team without causing chaos
Share Custom GPTs with one owner, one live version, and clear edit rights. Kill ghost copies before the team trusts disagreeing answers.
How tokens and context windows decide what an AI remembers and what it costs
Treat context windows like a suitcase: pack role, schema crumbs, and the question. Chunk instead of cramming. Tokens are not free, and middle content gets lost first.
How much to supervise Claude Cowork: when to watch and when to walk away
Choose Manual, Auto, or Skip with eyes open. Deletion always needs Allow. Watch high-stakes folders; do not equate Auto with unattended Skip.
