CompanyAI ModelsGatewayObservability

One unified, open layer to access models across providers and ship reliably.

Phaseo is built around practical openness: broad model and provider access, explicit release/deprecation/retirement tracking, and clear observability so teams can run production workloads with low surprise.

How It Works

A clear path from exploration to production operations.

Research models, execute through one API layer, stay current on lifecycle changes, and monitor behavior over time.

  1. Unified Model Access
    Step 1

    Browse and compare model capabilities and pricing across providers in one surface.

    • Access as many models and providers as possible from one place.
    • Compare capabilities, benchmarks, and cost using a consistent structure.
    Open Unified Model Access
  2. Gateway Execution
    Step 2

    Route requests across providers with an OpenAI-compatible API layer.

    • Keep integration code stable while provider offerings evolve.
    • Apply practical routing and control policies without lock-in.
    Open Gateway Execution
  3. Release Intelligence
    Step 3

    Stay current on launches, deprecations, and retirements as they happen.

    • Track release events without manual monitoring.
    • See what changed, what is sunsetting, and what to migrate to.
    Open Release Intelligence
  4. Request Observability
    Step 4

    Get clear signal on request behavior, reliability, and provider performance.

    • Inspect usage, errors, latency, and model/provider distribution.
    • Audit behavior over time and spot drift quickly.

Pricing

Platform pricing and model pricing are separate surfaces.

Use Phaseo Pricing for our platform/service pricing, and use the Pricing Calculator for model-level estimation.

Company

Open by default, explicit in behavior, clear in operations.

We prioritize transparent coverage and public documentation over vague claims. Compatibility, lifecycle updates, and observability are first-class.

Open by default

Access should be broad and practical, with consistent naming and clear docs.

Clear lifecycle signals

New releases, deprecations, and retirements are tracked so migration work is predictable.

Operational clarity

Request-level observability keeps behavior auditable and easier to debug in production.
