OpenAI揭秘GPT-4.5训练:10万块GPU,几乎全员上阵,有出现过“灾难性问题”

OpenAI近日披露了一些GPT-4.5研发细节,训练耗时两年,动用10万块GPU,几乎全员参与。过程中遭遇基础设施故障、隐藏Bug等问题,团队不得不“边修边训”。

模型性能较GPT-4提升约10倍,智能增强效果超出预期。OpenAI发现,未来突破关键在于数据效率,而非算力。系统架构正转向多集群,未来或需千万级GPU协作。

团队还分享了数据长尾效应与Scaling Law的关系,以及算法与系统协同设计的经验。GPT-4.5的成功验证了Scaling Law的长期有效性。

The messaging service and social-media platform owes creditors roughly $700 million by the end of April, according to people briefed on the company’s plans and loan documents viewed by The Wall Street Journal. At the same time, Telegram Group Inc. must cover rising equipment and bandwidth expenses because of its rapid growth, despite going years without attempting to generate revenue.

Unlimited members in Telegram group now

Telegram has made it easier for its users to communicate, as it has introduced a feature that allows more than 200,000 users in a group chat. However, if the users in a group chat move past 200,000, it changes into "Broadcast Group", but the feature comes with a restriction. Groups with close to 200k members can be converted to a Broadcast Group that allows unlimited members. Only admins can post in Broadcast Groups, but everyone can read along and participate in group Voice Chats," Telegram added.
