Large Language Model
Also: LLM
The technology behind AI tools like Claude, ChatGPT, and Gemini. An LLM is a type of AI trained on enormous amounts of text — books, websites, articles, code — until it learned to read, write, summarize, answer questions, and hold conversations. The 'large' refers to the scale of training and the model's internal complexity, not something you interact with directly. When people say 'AI,' they usually mean an LLM.
In practice
When you type a message to Claude and it writes back a coherent, relevant response — that's a large language model at work. It's software trained on enormous amounts of text until it learned to read, write, reason, and converse. The "large" refers to scale of training, not something you see directly. Claude, GPT-4, and Gemini are all LLMs.

9 articlesOpus 4.7 has five API breaking changes that will return 400 errors on existing code. Here's each one, the fix, and the full migration checklist. Also: Sonnet 4 and Opus 4 retire June 15, 2026.
On June 12, 2026, every Claude Fable 5 and Mythos 5 API call started failing — three days after the model launched. A US government directive disabled both models worldwide in hours. If your app had no fallback, it was just down. Here's how model loss happens, and how to build so it doesn't take you with it.
You've heard about AI. You've maybe tried it once, got something weird, and closed the tab. This is the honest version of what it is, why most people's first attempts disappoint them, and what to actually do.
Anthropic's flagship model gets a significant upgrade — better software engineering, 3.75-megapixel vision, and a new xhigh effort level. Pricing is unchanged. There are API breaking changes versus Opus 4.6.
A large language model is what Claude is at its core — and understanding how it works changes how you think about everything else in AI.
Anthropic's new tool lets you create prototypes, slide decks, one-pagers, and full design systems by describing what you want. Output is exportable as PDF, URL, or PPTX and can connect to your existing design files. Available in research preview for Pro, Max, Team, and Enterprise.
Anthropic's new flagship launched May 28, 2026. Pricing is unchanged at $5/$25. Effort now defaults to high, fast mode is 3x cheaper, and a 1M context window ships by default. Unlike the 4.6→4.7 jump, there are no new breaking changes — moving from Opus 4.7 is a model-name swap.
Anthropic launched Claude Fable 5 on June 9, 2026 — its most capable widely released model — then disabled it worldwide on June 12 to comply with a US government export-control directive. It costs $10/$50 per million tokens (double Opus 4.8), and it's the first Claude model that can decline a request mid-API-call. Here's what the model is, why it was pulled, and what to do while access is suspended.
Anthropic launched Claude Sonnet 5 on June 30, 2026 and made it the default model for Free and Pro the next day. It runs agents — planning, tool use, long autonomous tasks — at close to Opus 4.8 quality for a fraction of the cost: $2/$10 per million tokens through August 31. Three migration changes and a new tokenizer are the things to check before you swap the model string.
