GPT-5.6 Sol大降价，OpenAI把价格战烧到旗舰

Abstract

OpenAI对其旗舰模型GPT-5.6 Sol的API价格进行大幅下调，输入token价格从每百万5美元降至4美元，输出token价格则从30美元大幅降至20美元，综合降价幅度超过20%，其中输出降幅达33%。此次降价主要针对按token计费的API调用，使用量越大的用户节省越多。订阅套餐价格未变。 官方表示降价源于模型运行效率提升和推理成本下降。分析认为，此次降价旨在向正进行IPO路演的竞争对手Anthropic施加压力，抢夺其用户，同时也是对中国市场涌现的DeepSeek等低价模型的一种防守。OpenAI近期在算力基础设施上大规模投入，为其提供了降价空间。 同日，OpenAI旗下代码助手Codex宣布周活跃用户突破2000万，并为此发放了重置额度。官方同时明确，反对将订阅账号通过非官方渠道转售或共享的行为。

未来三个月,API 价格和 credit 价格(超出计划包含额度后的按需付费用量)一起砍掉超过20%。

目前,API 端已经即时生效,符合条件的 ChatGPT Work 和 Codex credits 正在陆续推送。

不过,Pro、Plus、Business三档订阅,一分不降。套餐里包含的用量也没给涨。

降的全是按token计费的那部分。也就是说,API调用量越大的人,省得越多。

到底能省多少钱?

Sol 此前的API定价是每百万token输入5美元、输出30美元,是GPT-5.6家族里最贵的。

现在翻开定价页,输入4美元,输出20美元。

输入降了两成,没毛病。但输出这一刀从30美元砍到20美元,整整砍掉三分之一。

所以,官方说降价「超过 20%」还算克制。真正最贵的输出 token,一下子降了 33%。

假设一个大型 Agent 每月消耗 1 亿输入 token、2000 万输出 token,原来要 1100 美元,现在只要 800 美元,综合降幅约27.3%。

具体省多少,全看你的输入输出比。批量处理文档那种重输入的活儿,大概省两成多;而Codex里疯狂写代码、输出占大头的场景,能省到三成往上。

一句话,越是把Sol当生产力工具往死里用的人,这次省得越多。

缓存那一档也跟着调整:缓存输入从0.5美元降到0.4美元,缓存写入从6.25美元降到5美元。长上下文档位同样下调,输入从10美元降到8美元,输出从45美元降到30美元。

OpenAI Developers随后跟帖表示,价格能降是因为现在Sol跑起来更有效率了。

ASI双雄决赛:价格成了第二战场

OpenAI 上一轮降价时,Sol是唯一没动的那个模型。

Luna一口气砍掉80%,主力Terra降两成。只有旗舰Sol稳坐原价,只是多给了一个加速不加价的Fast mode。

当时 OpenAI 的算盘打得很清楚:便宜的模型负责走量,最贵的那张牌撑起场面。

这一次,轮到Sol自己下场了。而在这个时间节点,怎么看都不像巧合。

科技大v博主Chubby的判断很直接:这是明摆着冲着Anthropic来的。

Anthropic眼下并不好过。Opus 5的负面反馈还没消化完,Fable 5订阅计划的速率限制又被用户追着骂。

OpenAI 这时候大降价,就是要挖 Anthropic 的用户墙角。

科技记者tae kim说得更狠:OpenAI这是在Anthropic的IPO路演里,使了点商战手腕。

这话可不是空穴来风。

Anthropic今年6月1日向S EC 递交了S-1机密文件,正式启动IPO流程。据多家媒体报道,承销银行从7月中旬就开始安排管理层与潜在投资者的会面,路演窗口恰好就是8月到9月。

目标上市时间:最快10月,纳斯达克,估值瞄着2万亿美元。

路演路上,最怕的就是竞争对手搞事情。

跑分站打完之后,价格成了ASI双雄决赛的第二战场。

OpenAI 敢疯狂砍价,也不是一时冲动。

他们早前激进的自建算力、押注更高效的模型架构,现在开始显现出威力了。

就在几天前,OpenAI刚宣布在俄亥俄州Pike County的PORTS-Pike园区锁定约8 IT-GW算力,OpenAI签下20年租约;NVIDIA独家提供AI计算基础设施。

此前,OpenAI还与Oracle达成超过3000亿美元、对应最高4.5GW新增容量的五年合作,并与AMD签下6GW GPU部署协议。

OpenAI今年4月已确认,锁定的AI基础设施容量超过10GW,目标到2030年扩至30GW。

基础设施越完善,边际成本越低,降价空间越大。这是一个正向飞轮:模型效率提升→推理成本下降→价格空间释放→用户涌入→收入增长→再投基建。

可以说,OpenAI 这个飞轮正在起飞。他们自己也说了,GPT-5.6 Sol参与优化了自己的生产推理内核,把端到端服务成本砍了20%,token生成效率提升超过15%。

但这次降价除了主动制造压力,也有被迫的成分。

DeepSeek V4 Flash在7月31日正式发布,价格跟不要钱似的。

更刺激的是两天前冒出来的一个代号为「Ox Alpha」的神秘模型。1M上下文窗口,支持文本、图片和视频输入,免费用一周。

现在,中国的开源模型不光便宜,能力也在不断逼近前沿模型。

所以Sol这波降价,既是对Anthropic的主动进攻,也是对中国低价模型的防守反击。

Codex破2000万

同一天还有另一组数字。

Codex 负责人 Tibo 宣布,Codex本周活跃用户突破2000万。

为了庆祝这个里程碑,团队给所有Codex和ChatGPT Work用户统一发放了一次BANKED重置额度。

不过,对社区反映的额度消耗过快问题,Tibo说目前没有发现异常,但正式调查已经启动,有结果会第一时间同步。

他还顺手划了一条线:把订阅账号通过sub2api转成API流量,再转售或者多人共享的行为,官方不支持。这类用法会被风控系统直接标记。

一个包月账号拆开卖给一百个人用,这条路堵死了。

通过官方客户端,或者Pi、OpenCode这些开源客户端正常使用,则完全没问题。

A Crucial Event is Approaching, Pay Attention to Friday: This Could Be the Fed's Most Important Event This Year

Federal Reserve Chair Kevin Warsh is preparing to deliver one of his most significant speeches this week at the Jackson Hole symposium. Markets and Fed officials are focused on a fundamental question: Is persistently high U.S. inflation due to temporary shocks like tariffs and the war with Iran, or is the economy still too strong from a demand perspective? The answer could determine whether the Fed will raise interest rates in the coming period. Investors will scrutinize Warsh's Friday speech for clues about his economic assessment and the conditions under which he might tighten monetary policy. The outlook is interpreted through two scenarios. One suggests inflation has exceeded the Fed's 2% target for over a year due to temporary shocks and may recede spontaneously. The other warns these events mask deeper economic imbalances, where strong demand allows companies to keep raising prices, potentially necessitating rate hikes. While recent softer inflation data has eased pressure for a September rate hike, concerns remain that the Iran war, new tariffs, and a surge in AI investment could exert lasting upward pressure on prices. Divisions within the Fed are growing, with some officials pushing for further tightening, citing robust consumer spending and labor demand, while others believe price pressures may ease on their own. A notable feature of Warsh's tenure has been his reduced guidance to markets, arguing central bankers talk too much. However, this reluctance to share his own views may be making it harder to build consensus, as evidenced by three dissenting votes for a rate hike last month—the highest in nearly a decade. Market reactions are being closely watched. Following the July meeting, the yield on the 30-year U.S. Treasury note rose to its highest level since 2007, suggesting investors believe the Fed might tolerate slightly higher near-term inflation but could require more significant future rate increases. Therefore, the Jackson Hole speech is crucial not only for near-term rate expectations but also for understanding how Fed policy communication will be shaped under Warsh's leadership.

SEC sends crypto custody rule overhaul to White House for review

The U.S. Securities and Exchange Commission (SEC) has sent a proposed overhaul of its custody rules for investment advisers and funds to the White House for review. The changes aim to provide clearer guidance on how institutions can hold cryptocurrency assets for clients while complying with federal securities laws. The proposal was submitted to the Office of Information and Regulatory Affairs on August 25. Once reviewed, it will return to the SEC for a potential vote to release it for public comment. The move is part of the agency's broader shift under Chair Paul Atkins towards formal rulemaking for crypto, moving away from its previous "regulation through enforcement" strategy. This follows the SEC's dismissal of several high-profile crypto cases in 2025.

Bitcoin dips below $78K as stocks, gold fall on higher US PCE Inflation data

Bitcoin fell below $78,000 after the release of higher-than-expected US PCE inflation data for July, which showed a 3.7% year-on-year increase versus a forecast of 3.6%. The data pressured risk assets, with US stocks and gold also declining. Markets now await Nvidia's Q2 earnings report as a potential short-term volatility catalyst. Analysis warns that Bitcoin's recent weekly gains of over 25% could constitute a bear market relief rally. Trader Rekt Capital highlighted the importance of Bitcoin's upcoming monthly close, noting that a failure to break a pattern of lower highs since October 2025 would confirm the downtrend. Key resistance to watch is the 50-week exponential moving average around $77,251.

Analysts Have Identified Three Key Signals for Bitcoin's Next Move

Analysts have identified three key macroeconomic signals that could determine Bitcoin's direction this week. The first is the upcoming July PCE inflation report in the US. A reading higher than expected (forecast at 3.2% year-over-year) could fuel fears of a Federal Reserve rate hike, putting pressure on Bitcoin, which is already showing signs of being overbought after retreating below $79,000. Markets currently price in a 40% chance of a September rate increase. The second signal is Nvidia's Q2 earnings. Strong results could bolster risk appetite, which is relevant for Bitcoin given its positive correlation with Nvidia's stock. Bitcoin recently had its largest weekly dollar gain ever, rising from ~$63k to ~$79k. The third catalyst is Fed Chair Kevin Warsh's speech at the Jackson Hole symposium. Investors will watch for clues on future policy, especially regarding Treasury yields. For the bullish trend to continue, analysts say Bitcoin needs to hold above its 365-day moving average near $83,000. Some forecasts remain optimistic, with Bernstein predicting a rise to $125,000 by end-2026 and a cycle peak near $300,000 in 2029.
