Chinese lab shipping open-weight MoE models. The V4 family (previewed April 24, 2026) runs a 1M context on DeepSeek's API; R1 (2025) popularized open reasoning models. Low-cost API.

Meta's open-weight model family. Llama 4, released April 5, 2025, comes in Scout (109B total, 17B active) and Maverick (400B total, 17B active). Commercial use under the Llama license.

OpenAI's chat app. As of October 2026 Free and Go run GPT-6 Luna; Plus ($20/mo) adds GPT-6.1 Sol and GPT-6 Astra. Agent mode, Codex, image generation, code interpreter.

Unified API for hundreds of models. One API key, one billing dashboard. OpenAI, Anthropic, Google, Meta, Mistral, and more. Automatic fallbacks and load balancing.

AI voice dictation for Mac, Windows, iOS, and Android. Works in any app - code editors, browsers, notes. Understands context and formats output appropriately. Faster than typing for prose.

Claude Code is Anthropic's AI coding agent for terminal, IDE, desktop and browser. What it does, how it works, setup, pricing, MCP, skills, hooks and subagents.

How RAG works, why it matters, and how to implement it in TypeScript. The technique that lets AI models use your data without fine-tuning.

Install the dd CLI and scaffold your first AI-powered app in under a minute: Next.js 16, Convex, Clerk, Autumn, Tailwind v4 and an agent-ready CLAUDE.md.

What MCP servers are, how AI clients like Claude Code call their tools, how to add one through .mcp.json, and how to build your own in TypeScript.

Claude Code /loop runs prompts on repeat in a session: fixed or self-paced intervals, seven-day expiry, jitter, and when Routines fit better.

State-of-the-art computer use, steerable thinking you can redirect mid-response, and a million tokens of context. GPT 5.4 is OpenAI's most capable model yet.

Claude Code updates: remote control from your phone, Cowork scheduled tasks, new plugin repos, auto memory and 4% of public GitHub commits now from Claude Code.

Mercury 2 from Inception Labs is a diffusion reasoning LLM that refines outputs in parallel at over 1,000 tokens per second. How it works and where it fits.

Claude Code worktrees let multiple agents work on one repo in parallel, each in its own branch and directory. Set up sub-agent isolation and keep main clean.

Claude Sonnet 4.6 nears Opus on agentic work and computer use at half the cost. Benchmarks, adaptive thinking, model card findings and the 1M context beta.

Claude Opus 4.6 adds agent teams, a million-token context window, adaptive thinking and context compaction. The benchmarks and what changes for agentic coding.

Why Claude Code won: terminal agents fit how software already works - files, shell commands, git, logs and project memory. The architecture behind the tool.

Claude Cowork brings the Claude Code agent loop to non-coding work like decks and documents. What it is, which plans include it and what changed since launch.

Progressive disclosure lets agents load tools only when needed. How Cloudflare, Anthropic and Cursor cut token usage, and how to do it in Claude Code.
