Responses API
relay 支持 OpenAI Responses API（新一代有状态对话 API）及旧版 Completions、Moderations。
Responses（同步）
resp, err := client.Responses(ctx, &relay.ResponsesRequest{
Model: "gpt-4o",
Input: []relay.ResponsesInputItem{
{Type: "message", Role: "user", Content: "Hello"},
},
Instructions: "You are a helpful assistant.",
})
fmt.Println(resp.Output)Responses Compact
精简版请求，适合简单单轮：
resp, err := client.ResponsesCompact(ctx, &relay.ResponsesRequest{
Model: "gpt-4o",
Input: []relay.ResponsesInputItem{{Role: "user", Content: "Hi"}},
})Alpha Search
部分 provider 支持的搜索增强 Responses：
resp, err := client.AlphaSearch(ctx, &relay.AlphaSearchRequest{
Model: "gpt-4o",
Query: "latest Go 1.26 features",
})旧版 Completions
resp, err := client.Completions(ctx, &relay.CompletionsRequest{
Model: "gpt-3.5-turbo-instruct",
Prompt: "Write a tagline for a coffee shop:",
})
fmt.Println(resp.Choices[0].Text)内容审核 Moderations
resp, err := client.Moderations(ctx, &relay.ModerationsRequest{
Model: "text-moderation-latest",
Input: "content to check",
})
for _, r := range resp.Results {
fmt.Println(r.Flagged, r.Categories)
