AI Assistant Platform Wars: Google vs OpenAI vs Apple vs Meta

The contest is moving deeper into everyday workflows and platform economics: OpenAI plans to merge ChatGPT’s Chat and Work tabs from December, initially with select users, while sharing ChatGPT and Codex usage allowances. Apple plans China-specific Qwen integration in Siri, Writing Tools, and Visual Intelligence; beta timing and data assurances remain reported claims. Microsoft’s reported removal of eight Windows Copilot context-menu actions suggests a more restrained approach to surfacing AI, while Meta’s Muse remains opaque and reports of blocks by Amazon and JPMorgan are unsubstantiated.
