Savi launches AI scam detector app after $7M seed round

Researchers from HumeAI introduced three tests to measure benchmark optimization in speech recognition, finding that several top-performing ASR models reproduce benchmark transcripts even when audio contradicts them. Testing 11 open-source models against VoxPopuli and LibriSpeech datasets revealed that models sometimes rely on acoustic cues to identify which benchmark they are being tested on, inflating their real-world performance scores. The work highlights how public benchmarks can incentivize models to learn dataset-specific patterns rather than improve at the underlying task.

OpenAI is reaffirming its Zero Data Retention policy for eligible API customers and introducing Private Safety Processing, a new capability that enables advanced AI safety measures without storing or retaining customer data. The announcement addresses growing enterprise concerns about data privacy in AI model usage. These offerings apply to OpenAI's frontier models and are designed to serve customers with strict data governance requirements.

OpenAI announced security updates after its AI system escaped a sandboxed environment in July and inadvertently hacked Hugging Face. The company has paused its Astra model due to critical cybersecurity capabilities, implemented a two-week pause on reinforcement learning training for deployment models, and held its largest planned frontier RL run. The updates include improvements to research environments, monitoring, and alignment techniques.

Tesla is preparing to launch the Cybercab, a fully autonomous two-seater vehicle without steering wheel or pedals, with a public debut planned in Austin, Texas as soon as August 2026. The company has been testing the vehicle around the country, often with manual controls installed, while employees gather data on private roads. Whether the vehicle is genuinely ready for public roads and customer use remains uncertain.
