Model limit probe

Morph: Morph V3 Fast | concurrency limit

Morph: Morph V3 Fast concurrency limit decides whether a key can enter a production route. TestKey reads model ID morph/morph-v3-fast, provider Morph, catalog context, real-key headers, 429 errors, and region signals together.

Why this limit matters

Morph: Morph V3 Fast concurrency limit decides whether a key can enter a production route. TestKey reads model ID morph/morph-v3-fast, provider Morph, catalog context, real-key headers, 429 errors, and region signals together.

Model: morph/morph-v3-fast
Provider: Morph
Limit dimension: concurrency limit

How to prove it

Read-only check. Detection data burns after 5 minutes.

Start with the visible signal: real key probe required, then read headers and error bodies with read-only requests.
concurrency limit must bind model ID morph/morph-v3-fast; limits from another model at the same provider cannot be reused.

Operator action

Morph: Morph V3 Fast concurrency limit is not just a number. It should become route throttling, sale tags, headroom alerts, fallback model suggestions, and price protection.
