The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
Google has introduced Gemini 4 Hydrogen, priced at $1.50 per million input tokens and $7.50 per million output tokens. It is rolling out today in the Gemini app, Google Search, and the Gemini API, and it finishes tasks 2.5 times faster than Gemini 3.8 Flash at the default high setting.
Google is rolling out Orchestrator in Antigravity for Google AI Ultra subscribers. It pairs Gemini 4 Carbon with Gemini 4 Hydrogen in one session, and on one test it used less quota and finished faster than Carbon alone.
DeepSeek has opened web search, file input, URL reading, and safety checks on the deepseek-flash API. Search, Fetch, OCR, speech recognition, and text-to-speech are also available as standalone calls.
Anthropic has published 10 recommendations for designing, running, and reporting safety evaluations. The company has paused many tests that give models internet access and now monitors the web-search tests that still need a connection.
LangChain has raised $300 million at a $3 billion valuation in a Series C led by CapitalG. More than 7,000 organizations use LangSmith, and a release event on November 20 will cover new capabilities.
