| Pricing model | freemium | free |
| Headline pricing | Free tier + SuperGrok $30/mo + Heavy $300/mo (or X Premium+ $40/mo) | Free with iOS 27 / macOS 27 — no subscription tier announced |
| Free tier | Genuinely usable: free accounts get Grok chat, live X data and Imagine Image 2.0 including Quality Mode. The catch is that xAI does not publish the daily limits, and they tighten under load. | Everything is the free tier — Apple has not announced a paid Siri or Apple Intelligence subscription. Costs that do appear are adjacent: iCloud+ storage, and any third-party model subscription you choose to link. Confirm on apple.com/apple-intelligence before quoting. |

Pros and cons
Grok
Chatbots · freemium
Pros
- ✓Real-time X/Twitter data integration remains unmatched by any competing chatbot, at any tier
- ✓One $30/mo subscription bundles a frontier chat model, a v1.0 terminal coding agent, image generation with in-model editing, and image-to-video with audio
- ✓Free tier reaches Imagine Image 2.0 Quality Mode — the same engine paid users get, which most rivals gate behind a subscription
- ✓Grok 4.5's adoption by Cursor and Perplexity is real external evidence of frontier-level coding ability, not just a vendor claim
- ✓More permissive content policies than competitors, with fewer refusals on political or edgy topics
Cons
- ×No computer use, which now ships inside the ChatGPT, Claude and Gemini subscriptions most buyers already hold
- ×xAI publishes very little that can be verified: no free-tier rate limits, no stated context-window size, few independent benchmarks
- ×Release churn is disorienting — 4.5 landed in July with 4.6 and 4.7 signaled within weeks, so documentation and workflows go stale fast
- ×Heavy reliance on X data can skew answers toward Twitter-centric framing, and the $300/mo Heavy tier is hard to justify without extreme rate-limit needs
Siri AI
Chatbots · free
Pros
- ✓Personal context across Messages, Mail, Calendar, Photos and Files that no cloud-first assistant can match without you uploading the same data
- ✓Free with the OS, on roughly a billion active devices — zero friction, no subscription, no separate app to adopt
- ✓Private Cloud Compute is a real architectural distinction, not a policy promise: attestable enclaves, no retention, independently inspectable server images
- ✓Onscreen awareness and App Intents make it an OS-level actor rather than a chat window you copy-paste out of
- ✓Developers can call the on-device foundation model free of per-token cost through the Foundation Models framework
Cons
- ×Reasoning depth trails ChatGPT, Claude and Gemini badly — hard analytical and long-form work still gets handed off to a third-party model
- ×Apple's delivery record on this specific feature is the category's worst: demoed June 2024, withdrawn March 2025, shipped 2026
- ×Locked to Apple hardware — no Android, no Windows, no web client, and older devices without Apple Intelligence support are excluded outright
- ×Third-party app control is only as good as each developer's App Intents adoption, so agentic coverage is patchy outside Apple's own apps
