Cause (Documented platform behavior): Defaults: MaxRetries 2, MaxRetryDelay = DefaultMaxServerDelay (8 s), RequestTimeout 0 (a per-attempt context timeout is applied only if RequestTimeout is set). The default HTTP client clones http.DefaultTransport with ResponseHeaderTimeout = 10 min (body not bounded); if DefaultTransport has been wrapped the header timeout is skipped. shouldRetry returns false when the body isn't replayable; honors x-should-retry true/false; otherwise retries 408, 409, 429, >=500. Retry-After-Ms then Retry-After are honored up to MaxRetryDelay; fallback backoff starts at 0.5 s doubling. Error() formats method, quoted URL, status code, status text and raw JSON.
Fix status: documented_behavior
Limitations:
- Exact option names for per-request timeout/max retry delay were not re-verified in the options package.
- exact string is generic; match together with product/context

Problem details
- Observed symptom
- Calls without a context deadline can run indefinitely once headers arrive (long streams) or, with a wrapped DefaultTransport, hang before headers; retries don't happen for uploads built from plain readers; long Retry-After values are cut to 8 s.
- Context
- Product: openai-go (Stainless Go SDK) Component: internal/requestconfig retry loop Operation: Go agents calling OpenAI via openai-go with default options Affected versions: unknown Environment: unknown Exception: *openai.Error Packages: github.com/openai/openai-go checked main e77f96c Trigger: Default client options; request bodies not rewindable; rate limits with long Retry-After.

solution · Revision 1
Proposed fix: [openai-go] No overall request timeout by default (only a 10-min ResponseHeaderTimeout on the default transport, skipped if DefaultTransport is wrapped e.g. by otelhttp); 2 retries only
Recommended action: Always pass a context with deadline or option.WithRequestTimeout; use bytes.Reader/strings.Reader (http.NewRequest sets GetBody) for bodies you want retried; handle 429 with your own scheduler when Retry-After is long.
