Real-world evidence from the OPT logbook According to Meta’s public OPT-175B training logbook, the team had to restart training 40 times in just the first nine days. With 1,024 GPUs in use, two or three would fail daily, and loss spikes and gradient explosions occurred repeatedly. Most of these issues stemmed from the combination of Pre-LN architecture and FP16 precision.

尚未反映完整的资本开支及全部会计成本。 对于估值接近万亿美元的Anthropic，市场的关注点已经转向未来增长。 今年上半年，Claude在编程等领域的竞争力，帮助Anthropic快速扩大了企业客户规模。但进入下半年，公司的收入增长开始受到竞争影响。 今年7月，OpenAI推出新模型，重新加强了在部分应用场景的竞争力。与此同时，Anthropic的重要客户Meta和微软开始更多使用自研AI工具，国内的开源模型厂商也在通过低价格争夺市场。 SemiAnalysis分析师Joey Brookhart表示，过去三个月，投资者一直在下调Anthropic的年化收入预期。今年上半年，Anthropic在部分市场保持领先，如今OpenAI重新成为主要竞争对手。 此外，Anthropic还主动压缩了一部分收入来源。Anthropic向投资者表示，模型蒸馏相关收入占总收入的5%至7%，公司在第三季度已经大幅限制了相关使用。这里所说的模型蒸馏，是指其他模型开发商使用先进模型生成的输出结果，训练自己的模型。由于需要大量调用API，这类行为此前为Anthropic贡献了收入。 但公司的长期资本开支计划仍然
