Together AI has launched a new A/B testing feature for large language models in production environments. This tool allows developers to split live traffic between a control model and up to 20 variants, enabling real-world performance comparisons based on user engagement metrics. The platform handles traffic routing at the endpoint level, simplifying the process and avoiding complex client-side configurations. This advancement provides a streamlined approach for teams to assess and improve AI models based on actual user interactions, ensuring more effective deployment decisions.

© TechCrunch AIMicrosoft is finally shipping the hardware promised alongside Nvidia’s RTX Spark chip, targeting developers who want to run local AI agents without cloud dependency. The Surface Laptop Ultra and Dev Box feature unified memory and specialized cooling designed specifically for on-device model orchestration. More importantly, Windows 11 now includes Execution Containers, a sandboxing layer that lets multiple AI agents operate safely alongside user data. This moves the platform from just hosting models to actively managing agent context and actions locally. It signals a shift where the OS itself becomes the runtime environment for autonomous software.
© GitHub ChangelogAnthropic’s latest lightweight model is now live inside GitHub Copilot, targeting high-volume coding tasks like subagents and terminal work. Early benchmarks suggest it matches Sonnet 5 on many coding challenges while consuming significantly fewer tokens and steps. This availability across VS Code, JetBrains, and mobile apps gives developers a faster, cheaper option for routine edits without sacrificing quality. The gradual rollout means most users will see it soon, with admin controls allowing enterprises to manage access via model policies.
© The Verge AIThe Surface Laptop Ultra marks the commercial debut of Nvidia’s RTX Spark, an Arm-based chip designed to bring serious local AI inference to Windows laptops. Starting at $2,599, this device signals a shift toward premium hardware capable of running large models locally, moving beyond cloud dependency for enterprise and creative workflows. Microsoft pairs this with 'Hybrid Intelligence' features in Copilot, allowing the agent to access local files and take OS-level actions like filing taxes or managing emails. This isn't just a new laptop; it's the first concrete proof that Arm-based PC silicon can handle the thermal and memory demands of 120B+ parameter models on-device.
