Claude Code

Two models, one price tag: $10 per million input tokens, $50 per million output tokens. GPT-6 Astra shipped on September 3, Claude Fable 5.1 on September 1. Identical sticker prices, so the comparison looks simple. It is not. The sticker is the same, the bill is not. Run the same work through both and what you pay can double or halve depending on the shape of your workload. This post starts with where that gap comes from, then walks the benchmark table, and finishes with three concrete billing scenarios. ...

On September 1, 2026, Anthropic released Claude Fable 5.1 and Claude Mythos 5.1. It has been roughly three months since Claude Fable 5 launched, and this time there is no government directive and no surprise shutdown in the story. The headline is different: the sticker price did not move, but the cost of actually running the model dropped sharply. On top of that, Fable 5.1 beats last month’s Claude Opus 5 on every benchmark Anthropic published. Let’s look at the details. ...

Running Claude Code against a non-Claude model works, and you do it on a path the providers document themselves rather than through a hack. Ollama, Moonshot and Z.ai all publish an Anthropic-compatible endpoint. Setup comes down to three environment variables. This guide covers the steps for all three providers, how to make the configuration stick, and the errors people hit most 🔌 The Short Answer Three providers, three addresses Provider ANTHROPIC_BASE_URL Ollama (local) http://localhost:11434 Moonshot / Kimi https://api.moonshot.ai/anthropic Z.ai / GLM https://api.z.ai/api/anthropic MiniMax https://api.minimax.io/anthropic Alibaba / Qwen depends on the plan Add ANTHROPIC_AUTH_TOKEN and a model name and that’s the whole setup. ...

Claude Code isn’t a chat window in your browser. It opens in your terminal, reads your project’s files on its own, edits them, runs the tests and commits. Say “fix that bug” and the expectation is that it finds the file and changes it. This guide walks the path from install to your first code change, and gives a straight answer on the free-version question 🧑‍💻 The Short Answer If you only have a minute Install (Windows PowerShell): irm https://claude.ai/install.ps1 | iex Install (macOS, Linux, WSL): curl -fsSL https://claude.ai/install.sh | bash Start it: cd into your project and type claude No free tier: you need a Claude subscription (Pro, Max, Team, Enterprise) or a prepaid Console account First move: run /init to generate a CLAUDE.md for the project What Is Claude Code? Claude Code is Anthropic’s coding agent for the terminal. What separates it from a regular AI assistant is that it doesn’t only produce text. It has tools for reading files, writing files, running commands and searching the web, and it decides on its own which to use and in what order. ...

The list that pops up when you hit / in Claude Code is intimidating at first. A hundred-odd commands, half of them named in a way that gives nothing away, and your own custom commands mixed in with the built-ins. You don’t need all of them. Ten commands cover almost everything you do day to day, and the rest is reference material you look up when the moment arrives. This page gives you both: the ten first, then the full list grouped by what it’s for 🧰 ...
