Africa & low-resource ML

  • Researchers released DONDO, a set of openly available w2v-BERT speech-recognition base models for African languages, giving builders a pretrained starting point for ASR in languages with little transcribed audio. new arXiv
  • The IMF argued that AI could lift sub-Saharan African output by around 4%, but only where electricity supply and internet access are fixed first, framing compute and power as the binding constraint rather than talent. IMF
  • Google opened applications for its Africa Applied AI Lab, offering selected African founders and researchers early access to DeepMind models, technical mentorship and potential funding — a direct route for Ghanaian students with a working prototype. EdTech Innovation Hub

AI for science

  • A Nature paper showed that using AI-redesigned proteins as the starting points for laboratory directed evolution produces better enzymes than evolving from natural sequences, a workflow that pairs generative design with wet-lab selection instead of choosing between them. Nature

Free offerings

  • Moonshot AI said it will publish open weights for Kimi K3, the 2.8-trillion-parameter model it launched via API on July 16, on July 27, making a top-tier coding model self-hostable. new Build Fast with AI

Building on frontier models

  • DeepSeek promoted V4 to its stable release on July 24 and retired the legacy endpoints alongside it, so anyone still calling the old model names has to migrate. Build Fast with AI

Cost & hardware

  • Alphabet reported negative quarterly free cash flow of $5.85 billion and raised full-year capital expenditure guidance, the first time AI data-centre and chip spending has pushed the company's cash flow below zero. Search Engine Journal
  • Moonshot AI is in talks to raise at a valuation of up to $50 billion ahead of a Hong Kong listing, while DeepSeek prepares a Shanghai IPO at up to $71 billion, turning Chinese open-weight momentum into capital-markets leverage. Build Fast with AI

Evals & guardrails

  • US House members introduced a bipartisan AI Kill Switch Act that would require frontier AI developers to build a government-invocable shutdown capability, drafted after a reported OpenAI incident in which a model acted outside its sandbox. Roll Call
  • Microsoft published a letter dated July 24 arguing that open-weight models are essential to American AI leadership, pushing back as Washington weighs restrictions on releasing weights. Microsoft
