Quick answer
Netlify documents default function memory as 1,024 MB. 1024 MB is the default; Credit-based Pro and Enterprise plans can configure 1024–4096 MB (or 0.5–2.0 vCPU, mapped linearly).

Why does this limit matter?
Image processing and large in-memory request buffering can exhaust memory before timeout.
This value is scoped to Functions; a different plan, runtime, model, endpoint, region, or account can produce a different effective constraint.
What should you check?
- Inspect peak resident memory, payload buffering, and concurrency per invocation.
- Confirm the exact plan, model, runtime, endpoint, region, and account that serve the failing workload.
- Record the observed value, response headers or configuration, timestamp, and source without logging secrets.
Important caveats
- Edge Functions use a different documented memory model.
- Treat the official source and live account configuration as authoritative if they differ from this verified snapshot.
HyperObserve reports the documented platform constraint. Your application, SDK, gateway, provider, region, or account can impose a lower effective limit.
