Complete the non-streaming error lifecycle.
If client.chat() rejects, Lines 129-140 do not run. chatRequest() only sets STATUS.ERROR. GenuiChat.vue therefore does not receive its onFinish error payload, so it does not add the error message or save the conversation. Route non-streaming request failures through the same completion-error contract as streaming requests.

OpenAI Chat Completions API response object created Unix timestamp seconds official documentation
💡 Result:
In the OpenAI Chat Completions API, the response object contains a field named created [1][2]. This field represents the Unix timestamp (in seconds) of when the chat completion was created [1][2][3]. It is a standard numerical field present in both the standard ChatCompletion object and the ChatCompletionChunk object (for streamed responses) [4][3].

AI SDK GenerateTextResult response timestamp Date official documentation version
💡 Result:
In the Vercel AI SDK, the GenerateTextResult object does not contain a top-level timestamp property [1][2][3]. While some documentation references a timestamp: Date field within LanguageModelResponseMetadata (often accessed via the response property of the result) [4][5][6], the primary GenerateTextResult interface—which contains the generated text, content, tool calls, and usage information—does not include a timestamp directly [1][2][3]. If you require timing information related to the generation process, the SDK provides performance metrics within the steps or finalStep objects of the result [7]. These include: - stepTimeMs: The total time spent on the step [7]. - responseTimeMs: The time spent waiting for the language model response [7]. - timeBetweenOutputChunksMs: Timing statistics for gaps between output chunks [7]. For further implementation details or to verify the exact structure for your specific version, you should refer to the GenerateTextResult interface definition in the official AI SDK GitHub repository [1][2][3].

site:github.com/vercel/ai/tree/ai@5.0.10 packages/ai/src/generate-text GenerateTextResult response timestamp
💡 Result:
In the Vercel AI SDK, the generateText function's result object does not contain a direct timestamp property at the top level of the GenerateTextResult interface [1][2][3]. Instead, metadata about the response, including the timestamp, is nested within the response information of the steps [4][5]. Specifically: 1. Per-Step Access: You can access response metadata via the steps array or the finalStep property [1][6][7]. Each step contains a response object, which includes a timestamp (a Date object) [8][9][4]. 2. Implementation Detail: Internally, when generateText executes, it processes the response data to ensure a timestamp is present, falling back to new Date() if the provider does not supply one [4][5]. While earlier versions of the documentation or internal structures may have varied, the standard way to retrieve this information in the current AI SDK is through the finalStep.response.timestamp or the steps metadata [8][9][7]. Performance-related timing (such as responseTimeMs) is also available within the performance property of each step [7].

Vercel AI SDK 5.0.10 GenerateTextResult response timestamp LanguageModelResponseMetadata
💡 Result:
In the Vercel AI SDK, the LanguageModelResponseMetadata type includes a timestamp property that records when the generated response started [1][2]. The structure of LanguageModelResponseMetadata is defined as follows: - id: string (The unique ID for the generated response) [1][2] - timestamp: Date (The timestamp for the start of the generated response) [1][2] - modelId: string (The ID of the model used) [1][2] - messages: Array (The response messages generated) [1][2] - headers?: Record<string, string> (Optional response headers, for providers using HTTP) [1][2] - body?: unknown (Optional response body, for providers using HTTP) [1][2] When using generateText, this metadata is accessible via the response property on the returned GenerateTextResult object [3][4]. For example, you can access the timestamp using result.response.timestamp [4]. Note that while the SDK has evolved, this metadata structure remains consistent across versions, including the Vercel AI SDK 5.x series [5][1][2].

Use Unix seconds for created.
Date.now() returns milliseconds, but chat.completion.created requires Unix seconds. Set it to Math.floor(result.response.timestamp.getTime() / 1000) or divide the fallback Date.now() value by 1,000.
