Thinking Machines has released Inkling, a 975B-parameter mixture-of-experts model with 41B active parameters and multimodal reasoning. Simultaneously, Anthropic is preparing for a potential IPO later this year following a $65 billion funding round at a $965 billion valuation. OpenAI has also trained GPT-Red to iteratively generate adversarial prompts, which reduced failures on a prompt-injection benchmark by sixfold for GPT-5.6 Sol.

  • Thinking Machines released Inkling with a one-million-token context window and made it available for customization through Tinker.
  • Anthropic plans investor meetings led by Goldman Sachs, Morgan Stanley, and JPMorgan Chase as it prepares for a potential IPO later this year.
  • OpenAI's GPT-Red reduces failures on a difficult prompt-injection benchmark by sixfold when incorporated into training for GPT-5.6 Sol.
