OpenAI bought German startup Ona — formerly Gitpod — to give Codex persistent cloud-based agents, as Codex passes 5M weekly users. The coding-assistant race keeps consolidating around cloud agents; teams on Copilot, Cursor or Claude Code should watch Codex's enterprise push.
OpenAI replaced the GPT-4o-era model behind ChatGPT voice mode with GPT-Live, dropping the old 2024 knowledge cutoff. Better real-time voice quality raises the bar for conversational and phone-agent experiences buyers benchmark against.
Anthropic filed a confidential draft IPO after a $65B Series H reportedly valuing it near $965B; OpenAI is preparing its own confidential filing with Goldman and Morgan Stanley, potentially listing as soon as September. Public-market scrutiny should mean more disclosure and pricing stability for enterprise buyers standardizing on either.
OpenAI shipped GPT-5.6 to everyone: Sol for frontier reasoning and long-horizon agents (new max-reasoning effort and an 'ultra mode' that spawns subagents), Terra at ~2x lower cost than GPT-5.5, and Luna for cheap high-volume work. Sol set a new state of the art on Terminal-Bench 2.1.
