Frequently asked questions

What is ChatGPT's Ultrafast mode?
It is a faster processing mode for GPT-5.6 Sol powered by Cerebras chips. In a demo the model built a financial dashboard in 1 minute 50 seconds versus 12 minutes and 20 seconds in the standard mode.
Why is Anthropic adding watermarks to Claude output?
Anthropic embeds invisible patterns in text Claude generates to make AI output recognisable, in response to European rules on transparency of AI-generated content. The watermarks only attach to words the model chooses itself.
What is Grokbot?
Grokbot is xAI's newest product, powered by Grok 4.6. It combines the capabilities of a coding agent in a simple interface, where every thread is its own agent and agents can collaborate in a single conversation.
Which open-source models came out this week?
GLM 5.3 and DeepSeek V4 Pro appeared as competitive but inexpensive models, and Meta released Muse Glimmer, an open 30-billion-parameter model that runs locally on a desktop GPU.
