INTRODUCING CUSTOM AGENTS

Google has introduced Custom Agents in Antigravity 2.0 and the Antigravity CLI, with the Antigravity IDE following shortly. Custom Agents are specialized, file-based configurations that define a particular role with its own scoped instructions, tools, and constraints. The system keeps users' active contexts clean, minimizes token overhead, and gives them a predictable partner for specific tasks. Custom agents don't replace skills and dynamic subagents - they just provide even more customizability for another level of optimization.

OPENAI PAID $100 FOR A 4.2% CEREBRAS STAKE WEEKS BEFORE ULTRAFAST LAUNCH

Days before OpenAI previewed Ultrafast, a service tier that can run GPT-5.6 Sol at up to 750 output tokens a second, OpenAI exercised every vested Cerebras warrant share, acquiring 10,033,508 Class N shares at $0.00001 each for about $100 in cash. The stake has an implied value of near $2.3 billion, though the shares carry no votes. Cerebras is now running every competitive speed offering at OpenAI. OpenAI has yet to publish price, model ID, or general-availability date for Ultrafast.

DARIO AMODEI ON REGULATION AND THE MESSAGING AROUND AI

Either concentrating AI in the hands of a chosen few companies and politicians via regulation or distributing it widely is a false choice. Those in that frame of mind often underrate the decentralizing power of objective and fair institutional processes. The public's negative view of AI is fundamentally a crisis of trust. Ordinary people don't trust companies, governments, or the tech industry. AI companies have still yet to deliver on their big promises to benefit the world.
