Apple Joins Hands with Google's Gemini to Reshape Siri! AI Collaboration Ignites the Market, Google's Market Cap Surpasses $4 Trillion for the First Time

According to the latest news, Apple has selected Google's Gemini large model as the core engine for its next-generation AI voice assistant, Siri. The system is expected to be officially launched with iOS 20 in the second half of 2026. This major collaboration not only marks a key step for Apple in applying generative AI, but also breaks the long-standing situation where the two companies have been working independently on core AI technologies.

After the announcement, the capital market reacted quickly: Google's stock rose more than 1% during the trading session, hitting a new all-time high, with its total market value exceeding $4 trillion for the first time; Apple's stock also increased by 0.5%, reflecting investors' high recognition of this strong partnership.

For a long time, Siri has been criticized for its mechanical response and limited understanding. The introduction of Gemini—especially its multimodal understanding and contextual reasoning capabilities—is expected to fully unlock Siri's intelligent potential. The new system will support more natural conversation flows, cross-app task execution (such as "send the document mentioned in last week's meeting to Manager Zhang"), personalized memory retrieval, and other advanced features, truly upgrading Siri from an "instruction executor" to a "personal AI agent."

Notably, although Apple's self-developed Ajax large model has already entered internal testing, choosing to collaborate with Google is seen as a pragmatic move given Gemini's maturity in language understanding, safety alignment, and engineering deployment. This move also highlights the new logic in current AI competition: even the most closed ecosystems cannot avoid embracing open collaboration at key technology nodes.

For Google, the integration of Gemini into over 2 billion active Apple devices worldwide is not only the strongest endorsement of its technical strength, but will also greatly expand the reach of its AI ecosystem. For users, a smarter, more proactive, and more understanding Siri may finally be here.
