Sequence-to-sequence, or Seq2Seq, describes models that map an input sequence to an output sequence whose length may differ. Machine translation converts words in one language into another, speech recognition maps audio frames to text, and summarization produces a shorter sequence from a longer document. Many Seq2Seq systems use an encoder to represent the input and a decoder to generate output step by step, often with attention between them. Transformer encoder–decoder architectures largely replaced earlier recurrent designs. Training typically uses paired examples and token-level loss, while inference relies on greedy, beam, or sampling-based decoding. Quality depends on alignment, context limits, data coverage, and evaluation beyond surface overlap.
Micron crossed a $1 trillion market valuation for the first time as booming demand for AI memory chips pushed shares to record highs amid the expanding AI infrastructure race.
Google DeepMind says its new AlphaProof Nexus framework solved nine open Erdős problems using AI-guided formal verification, though CEO Demis Hassabis cautioned the system is still far from AGI.
OpenAI CEO Sam Altman said AI has not caused the large-scale white-collar job losses he once expected, adding that human interaction still plays a critical role in many professions.
Anthropic co-founder Chris Olah told the Vatican that AI development cannot be left solely to technology companies, warning about commercial incentives, labor disruption, and the growing complexity of frontier AI systems.
Ashton Kutcher’s venture firm Sound Ventures invested $30 million in OpenAI years ago. That stake could now be worth more than $2 billion if OpenAI goes public at a higher valuation.
Anthropic says its unreleased Mythos AI model has identified more than 10,000 high- and critical-severity software vulnerabilities as part of Project Glasswing, a cybersecurity initiative focused on protecting critical infrastructure and open-source software.
Pope Leo has called for stronger global oversight of artificial intelligence, warning that unchecked AI development could fuel misinformation, labor disruption, surveillance, and autonomous warfare.
AI startups are increasingly being accused of overstating annual recurring revenue by counting unsigned deployments, future contract value, and projected usage growth as current revenue.
Anthropic co-founder Chris Olah warned that AI development cannot be left solely to technology companies and called for greater oversight from governments, religious institutions, and civil society.
Microsoft has reportedly begun canceling many internal Claude Code licenses and shifting employees toward GitHub Copilot CLI as AI coding tool costs continue to rise across the tech industry.
