Not sure where to start? This week’s hottest software, models and stacks in three minutes.

AI Apps▾

AI software people use: from assistants like ChatGPT to tools for coding, video and workflows, picked by purpose.

For Agents▾

Software for AI: tools that let your agent (Claude Code, Codex, Cursor…) browse, read docs, run code and remember.

Models▾

Choose models, estimate cost, self-host: prices, rankings, benchmarks, free tiers and compute.

Solutions▾

A goal or an error message? Ready-made stacks, steps and fixes by scenario.

Learn▾

A systematic course from zero to the frontier, with an algorithm library, must-read papers and tutorials.

Frontier▾

Daily AI news, weekly highlights, the latest papers and how AI is changing every discipline.

Learn these first. Sorted by year.

ReAct (Reason + Act) Interleaves reasoning, actions and observations. 2022core Function Calling / Tool Use Models emit structured function calls that follow a JSON Schema. 2023core Reflexion Agents write verbal self-reflections after failures and reuse them. 2023core Generative Agents (Memory & Reflection) Agents with memory streams, reflection and planning simulate human life. 2023core Multi-Agent Conversation (AutoGen) Multiple specialised LLM agents converse and call tools to solve a task together. 2023core MemGPT (Hierarchical Agent Memory) LLM manages its own memory like an OS – paging between the context window and external storage. 2023core Model Context Protocol (MCP) An open protocol connecting AI apps to external tools and data. 2024core Agent–Computer Interface (SWE-agent) LM-tailored command interfaces that boost automated bug fixing. 2024core
