EVs can go farther than EPA-rated range as driving habits make the difference

Some EV owners say their real-world driving range exceeds estimates set by the U.S. Environmental Protection Agency, depending on speed, acceleration, regenerative braking and temperature. Drivers of Ford\'s E-Transit van reported summer ranges of about 140 to 150 miles versus an EPA rating of 116 miles, even with cargo. The EPA says it adjusts lab results downward to reflect real conditions, using correction factors and a combined city-highway weighting to produce its standardised estimate.

Microsoft releases Agent Lightning v1.0 agent reinforcement learning framework

Microsoft has released its agent reinforcement learning framework, Agent Lightning v1.0, on GitHub. The framework centers on a production harness that handles context building, tool execution and the agent-environment interaction loop, while the training engine observes only LLM Q&A logs. Microsoft said it used 6,000 training examples to train a Qwen3.5-9B model and raised its SWE-Bench Verified score to 56.4 from 41.8. Researchers cited benefits and cautioned about reward design and infrastructure needs.

Mystery AI model Ox Alpha confirmed as China\'s Z.ai product

China\'s AI research lab Z.ai has been confirmed as the developer of the anonymous coding model Ox Alpha. The model appeared on OpenRouter without a logo, company name or separate announcement and drew millions of developer queries in a week. It supports a 1,048,576-token context window and can handle text, images and video. Developers and researchers traced it through tokenizer fingerprinting, server-response comparisons and error-format tests.
