openai.NotFoundError: Error code: 404 - {'error': {'message': 'The model `gpt-3.5-turbo-16k-0613` has been deprecated, learn more here: https://platform.openai.com/docs/deprecations', 'type': 'invalid_request_error', 'param': None, 'code': 'model_not_found'}}原因分析
指定的模型gpt-3.5-turbo-16k-0613 已被 OpenAI 官方弃用。
解决方案
将代码中使用的模型名称更新为 OpenAI 提供的当前可用模型。例如，可以替换为gpt-3.5-turbo 或其他更新的模型。
# 示例：假设你的模型实例化代码是这样的
# model = ChatOpenAI(model_name="gpt-3.5-turbo-16k-0613")
# 修改为：
from langchain_openai import ChatOpenAI
# 选择一个当前可用的模型，例如：
model = ChatOpenAI(model_name="gpt-3.5-turbo")
# 或者其他更新的模型，如 "gpt-4", "gpt-4o" 等预防措施
- 定期检查模型状态：关注 OpenAI 官方文档或更新公告，了解模型是否有弃用或更新计划。
- 使用最新推荐模型：在开发时，优先选择 Langchain 和 OpenAI 官方推荐的最新稳定模型，以减少因模型更新导致问题的风险。
