Function ContextWindowFromHeaders

internal/cloud/cloud.go:118–128

ContextWindowFromHeaders reads X-Context-Window. Returns 0 when missing, malformed, or out of sane range; the caller reads 0 as "use the fallback". Local Ollama never sets it, so it keeps its config.yaml value.

(h http.Header)

// malformed, or out of sane range; the caller reads 0 as "use the fallback".
// Local Ollama never sets it, so it keeps its config.yaml value.
func ContextWindowFromHeaders(h http.Header) int {
	raw := h.Get(headerCtxWindow)
	if raw == "" {
		return 0
	}
	n, err := strconv.Atoi(raw)
	if err != nil || n < ctxWindowMin || n > ctxWindowMaxSane {
		return 0
	}
	return n
