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.
Sam Altman told TIME that OpenAI expects an internal system it would call AGI by year’s end, built on its unreleased Astra model, though the claim rests on a contested definition.
Bill Gates published a 6,000-word essay warning that the AI transition could be one of history’s most disruptive periods, urging new institutions and a plan before it’s too late.
King Slide Works, once known for cabinet hinges, now dominates the market for AI server rack rails, making founder Lin Tsung-chi Taiwan’s richest person.
An anonymous social media claim says OpenAI finished pretraining a 10-trillion-parameter model codenamed Bel, though nothing about it, including a claim about Anthropic’s compute, is confirmed.
OpenAI’s first custom inference chip, Jalapeño, delivered up to 1.9 times more work per watt and far lower latency than rival systems, with AI accelerating its own design.
