Apple rebuilt Siri from the ground up with Google's Gemini model for iOS 26.4. We tested it against Claude and ChatGPT to find out if Siri is finally competitive in 2026.
Apple announced a complete rebuild of Siri in 2026, partnering with Google to use its Gemini AI model running on Apple's Private Cloud Compute infrastructure. The new Siri is fundamentally different from previous versions — it is context-aware across apps, understands what is on your screen without being told, and can execute multi-step tasks across different applications. The model targeted for March 2026 release alongside iOS 26.4 represents Apple's most significant AI investment since the original iPhone. The key differentiation from ChatGPT and Claude is native iOS integration — Siri can see your screen, access your photos, read your emails and control apps in ways that browser-based AI tools cannot match.
The on-screen awareness is the most impressive feature. Ask Siri to summarise the email you are looking at, schedule the meeting mentioned in the message, or find the receipt you photographed last week — it handles these seamlessly in ways that require multiple steps in Claude or ChatGPT. For pure question answering, research and coding assistance, Claude and ChatGPT still produce significantly better results. The new Siri is a remarkable device-level assistant but it is not trying to be a coding tool or research platform — and it should not be evaluated as one.
Use new Siri for: device-level tasks, iOS automation, hands-free convenience, anything requiring screen awareness, tasks that integrate with Apple's ecosystem of apps and services. Use Claude for: complex coding, architectural decisions, long-form analysis, production TypeScript, large codebase work. Use ChatGPT for: fast research, mixed code and content workflows, image analysis, versatile multi-modal tasks. These three tools solve different problems and complement rather than replace each other. Most iPhone users who are also developers will end up using all three.
Apple's Private Cloud Compute approach means Siri requests are processed in isolated cloud environments that Apple claims cannot access. This is meaningfully different from ChatGPT and Claude where your prompts go to OpenAI and Anthropic's servers. For sensitive personal information — health data, financial details, private communications — Siri's privacy architecture is the most trustworthy of any major AI assistant. For professional coding work with proprietary code, Claude and Anthropic's privacy policy are still worth reading before use.
