Corti’s Speech Model Is the Case for Healthcare AI Specialists

The most interesting AI model release today is not another general-purpose system trying to win every leaderboard at once. It is a speech model arguing that some domains are too specific, too regulated, and too failure-sensitive for “good enough” transcription. Corti launched Symphony for Speech-to-Text, a clinical speech recognition model

NVIDIA’s Tiny Nemotron-CLIMB Models Are for People Who Cannot Afford to Guess at Scale

NVIDIA’s Tiny Nemotron-CLIMB Models Are for People Who Cannot Afford to Guess at Scale

NVIDIA’s Nemotron-CLIMB release is not trying to impress anyone in a chatbot arena. That is why it is worth paying attention to. The company published Nemotron-CLIMB Proxy Base Models on Hugging Face: two small decoder-only language models, one with 62 million parameters and one with 350 million, trained from

Codex-Spark Is OpenAI Splitting Coding Models Into Fast Hands and Slow Brains

Codex-Spark Is OpenAI Splitting Coding Models Into Fast Hands and Slow Brains

OpenAI’s most interesting coding-model launch this week is not another bigger brain for unattended pull requests. It is a smaller model designed to make the human stay in the loop because the loop finally feels fast enough. GPT-5.3-Codex-Spark is a research-preview variant of GPT-5.3-Codex aimed at real-time

xAI’s May 15 Retirement Turns Grok 4.3 Into the Default — and Makes Silent Redirects a Cost Risk

xAI’s May 15 Retirement Turns Grok 4.3 Into the Default — and Makes Silent Redirects a Cost Risk

xAI’s May 15 retirement notice looks like routine API housekeeping until you read the fine print: the deprecated slugs do not just die. They keep resolving, silently redirect to grok-4.3, and get billed at Grok 4.3 rates. That is a clever uptime move and a dangerous migration

Microsoft’s MDASH Says the Security Agent Is a System, Not a Model

Microsoft’s MDASH Says the Security Agent Is a System, Not a Model

Microsoft’s MDASH announcement looks like another frontier-AI benchmark post until you read the architecture. Then the actual story snaps into focus: the security agent is not a model. It is a factory. Microsoft says its new multi-model agentic security harness helped find 16 Windows vulnerabilities in the May 12

Frontier Cyber Models Are Now Outrunning the Benchmarks Built to Measure Them

Frontier Cyber Models Are Now Outrunning the Benchmarks Built to Measure Them

The scary part of the UK AI Security Institute’s latest cyber-model update is not that Claude Mythos Preview or GPT-5.5 can “do security work.” We already knew that. The scary part is that the measurement apparatus is starting to look underpowered. AISI says frontier models have now substantially

Gemini 3.1 Flash-Lite Makes the Cheap Model the Architecture Decision

The most important model in a production AI system is often not the smartest one. It is the cheap, fast, good-enough model that gets called 40 times before the expensive model ever sees the request. That is why Gemini 3.1 Flash-Lite deserves more attention than its name will probably

Gemini 3.1 Deep Think Is Google’s Answer to the Frontier Benchmark Knife Fight

Google’s Gemini 3.1 Deep Think update is not interesting because another lab found another benchmark where it can print a bigger number. That game is now mostly a knife fight in a spreadsheet. It is interesting because Google is no longer asking developers to believe Gemini is catching
