A system that uses AI to work towards a goal through making decisions and taking actions often using a variety of tools. The agent is specifically autonomous (or at least, partially autonomous) when it comes to many of these steps to decide and act, and only involves a human if told to do so (which is usually called Human in the Loop). Worth knowing that something like ChatGPT or a chatbot is not in itself an "agent" as it doesn't take action steps autonomously. Agents can use a variety of tools and systems and even different models, and can be multiple agents used together for different steps with different strengths, tasks and focuses (orchestration). Until recently, agents were usually used for work contexts to run workflows but with the emergence of Meta's Muse Agent, ChatGPT's dots, and Instinct personal agents are now in consumer's hands as has been long predicted. This is likely to impact commerce and ecommerce and well as person-to-person interactions

Agentic is an adjective that describes a system (or type of work) that can pursue goals usually in a multi-step manner and with some level of autonomy usually using AI. Using generative AI through a chat function like ChatGPT is not in itself agentic work. An agentic system isn't conscious, independent or even always reliable. Currently, the focus is on using agentic systems within tightly controlled workflows where they can bring efficiency and quality, and where humans are involved even if only as a supervisor at key steps.

How much a model can hold in its head at once, measured in tokens. If you go beyond this magical limit, the model starts forgetting what you told it just before. However, it won't tell you when it's reached that point. As technology has improved context windows have grown, but it's worth noting they're readily eaten up, especially in a chat with a lot of files (especially token-hungry ones), and also in chats with a lot of turns.
