Function New

internal/llm/llm.go:238–246

New builds a Client governed by the caller's context, not http.Client.Timeout. That timeout is end-to-end (it covers body reads) and would kill a slow but legitimate SSE stream mid-flight on slow local backends. tui.Model's turnCtx is the single cancellation source; connect-level safety (DNS/TCP) is

(base, model, token string)

// enough that a proxy hiccup heals invisibly, and a *permanently* failing
// request (e.g. a genuinely wrong model name 404ing forever) still surfaces
// after ~22s total instead of minutes.
var defaultRetryBackoff = []time.Duration{2 * time.Second, 5 * time.Second, 15 * time.Second}

type Client struct {
	BaseURL string
	Model   string
	Token   string // optional; empty = no Authorization header
	HTTP    *http.Client
	// IdleTimeout caps the wait for the next SSE frame (see streamIdleTimeout).
	// A field, not a bare const, only so tests can shorten it; New sets the
	// default and nothing else writes it.
