News reporting focused on AI and machine learning, covering the companies behind these technologies, their real-world applications, and the ethical concerns they raise. This includes areas like generative AI (large language models, text-to-image and video), speech tech, and predictive analytics.
xAI's Grok 4.3 model is now generally available on Amazon Bedrock, offering configurable reasoning effort, tool calling, and a 1 million token context window. The model runs on the Mantle inference engine and supports OpenAI-compatible APIs for easy integration into agentic workflows.
A new VentureBeat Pulse Research survey of 107 enterprises reveals a significant gap between AI infrastructure spending and the ability to track its economics. Most organizations run AI on hyperscalers and model APIs, but the next dollar is aimed at specialized compute they rarely use today. GPU utilization is at 50% or less for 83% of respondents, and fewer than half rigorously track compute costs. A majority plan to switch or add providers within the year.
Perplexity introduces 'Search as Code', a new architecture where AI models write their own search workflows as Python code instead of calling fixed APIs. The approach reduces token usage by 85% in a cybersecurity benchmark and beats rivals on four out of five tests. The system is rolling out in Perplexity Computer and the Agent API.
xAI released Custom Voices, allowing users to create a voice clone from one minute of speech. The feature includes security checks and integrates with existing APIs. A new Voice Library offers over 80 voices in 28 languages.
OpenAI added GPT-5.5 and GPT-5.5 Pro to its Chat Completions and Responses APIs on April 23, 2026. These models support a 1M token context window, image inputs, and various tools. The changelog details numerous updates from 2023 to 2026, including image, video, audio models, agent tools, and API improvements.
Salesforce CEO Marc Benioff states that APIs serve as the new user interface for AI agents. The company launches Headless 360 to expose its full platform, including Agentforce and Slack, via APIs, Model Context Protocol, and a Command Line Interface. This approach aligns with OpenAI CEO Sam Altman's view that every company must become an API company as AI agents bypass traditional interfaces.
IBM Research details VAKRA, a benchmark that tests AI agents on reasoning and tool use in enterprise settings. It features over 8,000 APIs across 62 domains and four capabilities focused on API chaining, tool selection, multi-hop reasoning, and multi-source tasks with policies. Analysis shows models like GPT-OSS-120B lead but all struggle with complex workflows, as revealed in error breakdowns and performance charts.
