# Availability as a Quality Metric

## Definition
The idea that a model's intelligence is irrelevant if it cannot be accessed when needed.

## Anchor Quote
See [[quote-availability]]: *'The best model in the world is not useful if you can't use it when you need it.'*

## Components of Availability
- **Uptime** — how often the API answers at all.
- **Compute caps** — rate limits, daily quotas, session limits.
- **Routing latency** — how fast a request gets to compute.

## The Stated Gap
Per [[claim-anthropic-uptime-lag]]:
- [[entity-anthropic-d26|Anthropic]]'s Claude services operate at roughly **'one nine'** (~90-98% uptime).
- OpenAI's services operate at **'three nines'** (99.9%).

The practical consequence: for serious daily enterprise work, [[entity-gpt-5-5|GPT-5.5]] is the default choice simply because it is **consistently available**.

## Counter-Perspective
The enrichment overlay notes both providers face peak-load outages and that **no quantified 'three nines vs one nine' data is publicly available**. Treat the *direction* (Anthropic less reliable than OpenAI in early 2026) as plausibly supported by anecdote; treat the specific numbers as unverified.
