Fix #6201

将system role切换成user role或者developer role。

📝 补充信息 | Additional Information

当使用 Azure OpenAI 的 O-series 模型（如 o1, o1-mini 等）时，如果设定了 system prompt 会导致以下错误：

"error": {
  "message": "Unsupported value: 'messages[0].role' does not support 'system' with this model.",
  "type": "invalid_request_error",
  "param": "messages[0].role",
  "code": "unsupported_value"
}

我感觉是不是反了？目前支持 develop 的反而是少数。

这个是抄的这边的代码。我只有o1-mini的模型可以用来测试，改了之后是可以跑通的

lobe-chat/src/libs/agent-runtime/openai/index.ts

Lines 10 to 40 in 3e8d9c5

	export const pruneReasoningPayload = (payload: ChatStreamPayload) => {
	// TODO: 临时写法，后续要重构成 model card 展示配置
	const disableStreamModels = new Set([
	'o1',
	'o1-2024-12-17'
	]);
	const systemToUserModels = new Set([
	'o1-preview',
	'o1-preview-2024-09-12',
	'o1-mini',
	'o1-mini-2024-09-12',
	]);
	return {
	...payload,
	frequency_penalty: 0,
	messages: payload.messages.map((message: OpenAIChatMessage) => ({
	...message,
	role:
	message.role === 'system'
	? systemToUserModels.has(payload.model)
	? 'user'
	: 'developer'
	: message.role,
	})),
	presence_penalty: 0,
	stream: !disableStreamModels.has(payload.model),
	temperature: 1,
	top_p: 1,
	};
	};

不能照抄。

你自己看这里的变更，这个变换是加了约束的：

if (model.startsWith('o1') || model.startsWith('o3')) {}

[hcygnaw]

根据这篇帖子里的讨论，developer现在取代了过去的system。

我这边试过Azure的gpt-4o和gpt-4o-mini，都是能正常使用developer的role的。

如果这个provider 仅局限于 azure openai 的话估计没问题。但保不准有人用这个 provider 来调 phi-4 等其他模型吧？
