AI Competition Accelerates: GPT-6 May Be Released Within a Month, Anthropic's Mythos Drives Industry-Wide Shift to Larger-Scale Pretraining
AI Competition Accelerates: GPT-6 May Be Released Within a Month, Anthropic's Mythos Drives Industry-Wide Shift to Larger-Scale Pretraining

两条关于 GPT-5.6 和 GPT-6 的爆料。
先说最劲爆的一条：OpenAI 准备跳过 5.x 系列，直接推 GPT-6。
GPT-5.6 将是 5.x 系列的最后一个模型，GPT-6 大约一个月后发布，甚至可能 7 月底就到。GPT-5.6 刚在 6 月 26 日开始受限预览，明天（美国时间 7 月 9 日）才正式向公众开放，结果下一代已经在路上了。
按照爆料者的说法，GPT-6 将基于一个全新的、规模大得多的预训练底座。此前 GPT-5.5 和 GPT-5.6 共用代号“Spud”的预训练基座（约 4T token），OpenAI 原本打算沿用 Spud 继续做到 GPT-6，但临时改了主意。
改主意的原因：Anthropic 的 Mythos。
GPT-6 是 OpenAI 对 Mythos 的真正回应，Mythos 改变了一切，所有人都在往大了做。
Anthropic 6 月 9 日发布了 Fable 5 和 Mythos 5，其中 Mythos 5 的网络安全能力让美国政府紧张到直接下了出口管制令，要求 Anthropic 三天后就全面停止对外访问。虽然禁令已在 6 月 30 日解除，Fable 5 从 7 月 1 日起恢复使用，但这场风波本身就说明 Mythos 的能力级别确实跨越了新的门槛。
爆料中还提到，Fable 5.1 已进入 Anthropic 内部流程的后期阶段，预计几周内发布。这个时间窗口刚好和 GPT-6 的传闻发布期重叠，OpenAI 显然也意识到了这一点。
另一个值得注意的信号来自马斯克。Andrew Curran 提到 xAI 有一个 10T 参数的 Grok 正在训练中。这个说法和 5 月份马斯克本人透露的信息吻合，当时他确认 Grok V9（1.5T 参数）已完成训练，同时有 6T 和 10T 的版本在 Colossus 2 集群上并行训练。Grok 4.5 已于 6 月 28 日在 SpaceX 和 Tesla 内部开始测试。
中国这边也没闲着。DeepSeek V4 正式版计划 7 月中旬上线（4 月 24 日发布的是预览版），将引入高峰时段双倍定价机制。爆料者称 DeepSeek V4 正式版的能力可能追平甚至超过智谱 6 月 13 日发布的 GLM-5.2。
与此同时，DeepSeek 已经开始研发一个更大的新模型，目标是和 MiniMax 即将推出的 M3 Pro 竞争。据 The Information 报道，M3 Pro 总参数量 2.7T，计划在 Q3 开源，将是中国最大的开源模型。
把这些消息拼在一起看，2026 年下半年的 AI 竞赛格局已经清晰：美国几家头部实验室被 Anthropic 的 Mythos 级能力刺激，全面转向更大规模的预训练；中国实验室则在开源路线上加速追赶，GLM-5.2 和 DeepSeek V4 都在特定任务上逼近闭源前沿。
看起来 Scale Law 还没到头。Show More

I have also heard some of this independently, and believe the following to be true. GPT-6 is the next release from OpenAI. It's their true answer to Mythos, and it will arrive much sooner than people expect. Model release cadence has been speeding up for a while now. It's possible that GPT-6 even arrives within the next four weeks. When I say 'arrive', however, it may not mean a general release, because if the last couple of months are any indication, GPT-6 will almost certainly be held back by the government, at least initially.
It's a new, much larger pretrain as leo says. Mythos changed everything. Everyone is going big. Including Elon who has a 10T Grok in training. Both OpenAI and Anthropic see capabilities increasing rapidly, with advancement continuing on a new trajectory over the rest of this year and beyond. Both labs are very confident in what they have internally and see nothing above us but air. No ceiling.Show More

One Sentence Summary
Reports say OpenAI will skip the 5.x series and launch GPT-6 directly, possibly as a direct response to Anthropic's Mythos, while DeepSeek, xAI, and others are also accelerating the large model race.
Summary
Compiled by宝玉(@dotey) from multiple sources, the latest AI developments are revealed: OpenAI is preparing to skip the GPT-5.x series and directly release GPT-6 (based on an entirely new, much larger pretraining base), expected within a month; this is a response to the formidable capabilities of Anthropic's Mythos. Anthropic's Mythos 5, due to its cybersecurity prowess, once triggered U.S. export controls; Fable 5.1 is slated for imminent release. xAI is training a 10T‑parameter Grok. In China, DeepSeek V4's official version is set for mid‑July launch and will compete with MiniMax's upcoming M3 Pro. Overall, the AI competitive landscape for the second half of 2026 is now clear, and the Scaling Law shows no sign of ending.
