OpenAI

#3 · 7.2/10 overall

The assistant most people mean when they say 'AI'.

Still the default consumer assistant and a serious agent contender via agent mode and a deep API platform. Owns its models but leans on Microsoft for cloud and enterprise distribution. Weakest on the device edge.

Dimension breakdown
  • Assistant Intelligence
    9/10

    Frontier reasoning and the assistant most users measure everyone else against.

  • Agent Capability
    8/10

    Agent mode and Operator-style browsing ship real multi-step work, not just demos.

  • Conversational UX
    9/10

    Advanced Voice set the bar for latency, interruption handling, and natural turn-taking.

  • Cross-App Actions
    5/10

    Connectors and actions are expanding, but it reaches into apps from the outside, not the OS.

  • Personal Context
    7/10

    Persistent memory across chats is mature; lacks deep device/calendar/file grounding.

  • Third-Party Integrations
    7/10

    GPTs, connectors, and a growing app surface, but no open cross-vendor protocol of its own.

  • Developer APIs
    9/10

    The reference developer platform: tool use, structured output, Assistants, fine-tuning, scale.

  • Model Strategy
    9/10

    Owns the frontier model stack end to end; compute via Microsoft and increasingly its own.

  • Agent Platform Potential
    8/10

    Massive distribution plus an explicit agent push position it as a leading agent platform.

  • On-Device AI
    2/10

    Essentially no device or OS-level local-inference story of its own.

  • Enterprise Readiness
    7/10

    ChatGPT Enterprise and the Azure relationship give a real, fast-growing enterprise motion.

  • MyAGI Alignment
    6/10

    Highly capable, but a hosted assistant. Not yet a governable, revocable control plane with durable memory.

Trajectory

From the default consumer assistant toward a full agent platform. The open flank is the device edge and a hardware surface of its own.

  • Now
    Capability + distribution leader, no edge

    Frontier models, the best-known API, and a maturing agent mode, but no device story.

  • H2 2026
    Agent platform + a hardware bet

    Deeper agent infrastructure and a rumored dedicated device would attack the on-device gap that caps its scorecard.
