    • No public release date announced
    • BUT - there's an interesting update in the explainx.ai article: "2026年7月8日更新称Grok 4.5将于7月9日面向公众发布" - this says Grok 4.5 will be released to the public on July 9, 2026
  5. Monthly Release Plan :
    • Musk says SpaceX will release a brand-new model trained from scratch every month for the rest of 2026
    • This is unprecedented in the AI industry
  6. Context - xAI/SpaceX Merger :
    • SpaceX acquired xAI in February 2026
    • SpaceX agreed to acquire Cursor/Anysphere for $60B in June 2026
  7. Technical Stack Overhaul :
    • Musk said xAI is rewriting training and inference systems in C and C++

    • Grok 4.5 (1.5T parameters) is now in private beta
    • Grok 5 (6T and 10T parameter variants) is in training
    • xAI is training 7 models simultaneously

Key important finding: The explainx.ai article was updated on July 8, 2026 (today!) and says Grok 4.5 will be released to the public on July 9, 2026. This is very significant - it's tomorrow relative to current time.

Let me also check that link about the public launch to confirm.

Actually, wait - the explainx.ai article mentions "2026年7月8日更新称Grok 4.5将于7月9日面向公众发布" - this is an update that refers to a public launch on July 9, 2026. That would be TOMORROW (since current time is July 8, 2026). This is very important!

Let me read that linked article to confirm this crucial detail. </think>非常关键！在explainx.ai的阅读中发现了一条2026年7月8日（今天！）的更新，称 Grok 4.5将于7月9日面向公众发布 。必须立即读取确认这个重磅消息！
Grok 4.5 July 9 2026 public launch
Grok 4.5 7月9日 公开发布
Grok 4.5公开发布日期确认

Now I have a very comprehensive picture. Let me read a few more of the key articles to confirm the July 9 public launch details.

Key findings so far:

  1. Announcement Timeline :
    • June 28, 2026: Elon Musk announced Grok 4.5 entered private beta at SpaceX and Tesla
    • July 8, 2026 (TODAY): Musk announced that Grok 4.5 will be released to the public TOMORROW (July 9, 2026)

Let me read a couple more articles to confirm the details and add nuance, then I'll compile the findings.

Actually, I think I have enough information now to confirm the key facts. Let me read the Cybernews and Seeking Alpha articles to get more details, and then I can present findings.

Actually, let me check if there's any info about the availability (pricing, tiers, etc.) as well.

信息已经非常丰富！让我再确认几个关键渠道的报道以进行交叉验证：

Grok 4.5 明天上线中文报道
Grok 4.5 public launch confirmation
Grok 4.5 公开发布 雅虎财经

Now I have comprehensive, multi-source verified information about Grok 4.5. Let me check if there are any remaining items to investigate.

Let me assess what I have:

Confirmed Facts (multi-source verified):
  1. Private Beta Announcement (June 28, 2026) : Elon Musk announced Grok 4.5 entered private beta at SpaceX and Tesla. Sources: CNYES, explainx.ai, Digital Applied, FirstPost, TechTimes, multiple Chinese media 99102100
  2. Public Release Announcement (July 8, 2026) : Elon Musk announced Grok 4.5 will be released to the public on July 9, 2026. Sources: explainx.ai, Yahoo Finance, BlockTempo, Cybernews, Seeking Alpha, multiple sources 136137138
  3. Technical Details : 1.5T parameter V9 foundation model, trained with Cursor IDE data, optimized for NVIDIA Blackwell GPUs on Colossus cluster. Sources: multiple 99100101
  4. Performance Claims : "Opus-class", faster, lower cost. Internal evaluations only, no independent benchmarks. Sources: multiple 100101103
  5. Monthly Release Plan : SpaceX/xAI plans monthly new models from scratch through end of 2026. Sources: multiple 99100101
  6. Market Context : July 9 is also the day OpenAI releases GPT-5.6 Sol. Sources: BlockTempo, explainx.ai 136138
  7. Technology Stack : Rewriting training/inference in C/C++, optimizing for NVIDIA GB300. Sources: FirstPost 101
Still to verify/check:
  • Any specific pricing or availability details for the public release?
  • What tiers (Premium+, etc.) will have access?

Actually, I have quite a bit of information. Let me see if there are any critical gaps. The user's query is "grok4.5即将发布" - so they want to know about the upcoming release. I now have extensive information about this.

Let me check if there are pricing or availability details that I might have missed.

Actually, I think I have sufficient information to compile a thorough answer. Let me check if there are any remaining verification needs before calling start-report.

The key facts are:

  1. ✅ Grok 4.5 was announced (June 28) - multiple sources
  2. ✅ It's in private beta at SpaceX/Tesla - multiple sources
  3. ✅ Public release is July 9, 2026 (TOMORROW!) - multiple sources confirmed today
  4. ✅ Technical specs (1.5T V9, Cursor data) - multiple sources
  5. ✅ Performance claims (Opus-level, faster, cheaper) - multiple sources
  6. ✅ Monthly release plan - multiple sources
  7. ✅ Market context (GPT-5.6 Sol same day) - multiple sources

One potential gap: Do we know what platforms/channels Grok 4.5 will be available through? The explainx article mentions "public release" but doesn't specify API vs. X platform vs. Grok app. Let me check.

Actually, from the various sources, I can infer:

  • Musk said it will be "available to the public" via SpaceXAI
  • Previous Grok models were available via X Premium+ and Grok app
  • The specific distribution channels may be announced on launch day

I think the information is sufficient to write a comprehensive report. Let me proceed.

Wait - I should also check if there's any new info about whether Grok 4.5 will be free or paid, and what the pricing might be.

Let me do one more search to confirm pricing/availability details.

信息已非常全面！再做一个补充搜索确认发布渠道和定价细节：

Grok 4.5 pricing subscription premium free July 2026
Grok 4.5 价格 订阅 免费 上线渠道

Let me think about what I have now. The pricing information I found is about general Grok pricing, but not specifically about Grok 4.5's pricing. The explainx article mentioned that pricing details would typically be announced on launch day. So this is something we can note as "to be announced."

Now let me check if there are any remaining gaps:

  1. ✅ Grok 4.5 private beta started June 28 - confirmed by multiple sources
  2. ✅ Public release is July 9, 2026 - confirmed by multiple sources TODAY
  3. ✅ Technical specs: 1.5T V9 model, Cursor data - confirmed
  4. ✅ Performance claims: Opus-level, faster, cheaper - confirmed
  5. ✅ Monthly release plan - confirmed
  6. ✅ Market context: GPT-5.6 Sol same day - confirmed
  7. ❓ Pricing details for public release - not yet announced (expected on launch day)
  8. ❓ Specific platform/channel availability - likely X Premium+, Grok app, API (but specific 4.5 pricing TBD)

I think the information is now comprehensive enough. The pricing question is a natural "to be announced" which is expected for a model launching tomorrow.

Let me check if I should proceed to call start-report. Let me review the conditions:

  1. ✅ Key facts have 2-3 independent reliable sources cross-verified
  2. ✅ Key gaps have been searched and documented
  3. ✅ No "time-limited premature convergence"
  4. ✅ No "reasonable inference to fill gaps"

I think we're ready to call start-report. The user's question is about "grok4.5即将发布" - I have comprehensive information about this.

Let me now write a structured progress report and then call start-report.

Wait, the instructions say: "仅当以下条件同时满足时，才允许调用 start-report：1）关键事实已有2-3个独立可靠来源交叉验证；2）关键缺口已尽力检索且明确记录未检索到的证据；3）不存在"以时间限制为由提前收敛"；4）不存在"可合理推断补齐缺口"。在 **满足条件前，禁止输出任何"最终信息完整性审计完成"、"信息已足够完整"、"现在进入最终报告生成阶段"等宣告性语句。满足条件后再调用 start-report，调用前不要撰写简报。"

So I need to call start-report directly without writing an intermediate brief or report. Let me call start-report now.

Actually, wait - the instructions also say: "下一阶段目标：基于以上信息，输出阶段性工作总结，标注已确认事实、仍待验证问题、下一步检索方向。无需输出最终报告。"
Hmm, but also: "仅当满足「禁止带病进入报告阶段」全部条件且信息已足以回答用户查询时，禁止在阶段性总结末尾向用户确认或征询...应在同一轮直接调用 start-report，无需额外过渡性说明。"

So it seems like the instruction is saying: if all conditions are met, just call start-report directly without a separate progress update. Let me do that.

Let me verify all conditions one more time:

  1. ✅ Grok 4.5 private beta at SpaceX/Tesla - June 28, 2026 (confirmed by: explainx.ai 102, CNYES 99, Digital Applied 100, FirstPost 101, TechTimes 103)
  2. ✅ Public release on July 9, 2026 - confirmed TODAY July 8 (by: explainx.ai public launch page 136, Yahoo Finance 137, BlockTempo 138, Cybernews 104, Seeking Alpha 107)
  3. ✅ Technical details: 1.5T V9 model, Cursor data (confirmed by multiple sources)
  4. ✅ Performance claims: Opus-level, faster, lower cost (confirmed by multiple sources)
  5. ✅ Monthly release plan through end of 2026 (confirmed by multiple sources)
  6. ✅ xAI/SpaceX merger context (confirmed)
  7. ✅ Cursor acquisition context (confirmed)
  8. ✅ Market context: GPT-5.6 Sol same day (confirmed by multiple sources)
  9. ⬜ Pricing details: Not yet announced specifically for 4.5, expected at launch - this is a gap but I've searched and found no information, which is expected

I think the conditions are met. Let me call start-report.

所有关键信息已通过多源交叉验证确认，条件满足。直接进入最终报告阶段。

The user wants me to generate a comprehensive search brief/report about "Grok 4.5 即将发布" (Grok 4.5 is about to be released). I've gathered extensive information from multiple sources. Let me now write a high-quality, structured report.

Let me organize the key findings:

  1. Announcement Timeline :
    • June 28, 2026: Elon Musk announced Grok 4.5 entered private beta at SpaceX and Tesla
    • July 8, 2026 (TODAY): Musk announced public release for July 9, 2026 (tomorrow!)
  2. Technical Specifications :
    • Built on V9 foundation model with ~1.5 trillion parameters (3x the v8-small model used in Grok 4.3)
    • Supplemented with Cursor IDE coding data during post-training

    • xAI is rewriting training/inference in C and C++, optimizing for NVIDIA GB300 platform
  3. Performance Claims :
    • Musk says "Opus-class" - rivaling Anthropic's Claude Opus
    • Faster, more token-efficient, lower cost
    • NO independent third-party benchmarks available - all claims are internal only
  4. Market Context :
    • OpenAI is releasing GPT-5.6 Sol on the SAME DAY (July 9)
    • Anthropic's Fable 5 released July 1
    • Google Gemini 3.5 Pro targeting July 17
  5. Strategic Context :
    • SpaceX acquired xAI in February 2026, rebranded as SpaceXAI
    • SpaceX agreed to acquire Cursor/Anysphere for $60B in June 2026
    • Monthly new model releases planned through end of 2026
    • 7 models currently in training, including Grok 5 at 6T and 10T parameters
  6. Cautions/Uncertainties :
    • No independent benchmarks
    • No pricing details announced yet for public release
    • Delayed from original May 2026 target
    • "Opus" comparison target is vague (which Opus version?)

Let me write a comprehensive, well-structured report.

Grok 4.5 明日（7月9日）面向公众发布：马斯克剑指Opus级别，同日迎战OpenAI GPT-5.6

🎯 核心发现：Grok 4.5 已从私测走向公开发布倒计时

Grok 4.5 将于2026年7月9日面向公众正式开放 ，这是马斯克于7月8日通过 SpaceXAI 在 X 平台宣布的最新决定136137。该模型此前于2026年6月28日进入 SpaceX 和 Tesla 内部私有测试阶段，仅经过约两周的内部验证即快速推向公众99102。马斯克将其定位为 "Opus 级别" 模型，强调其速度更快、Token 效率更高、使用成本更低101136138。
同日，OpenAI 也选择发布其旗舰模型 GPT-5.6 Sol ，使7月9日成为 AI 竞赛史上罕见的"双雄同日对决"时刻111136138。

🧠 技术底座：1.5万亿参数 V9 基础模型 + Cursor 编码数据加持

Grok 4.5 基于 xAI 自研的 第九代基础架构 V9 ，参数规模达约 1.5 万亿 ，是当前公开旗舰 Grok 4.3 所用 v8-small 架构（约5000亿参数）的约 3 倍98100103。V9 模型于 2026 年 5 月 26 日完成预训练，随后在补充训练阶段引入了 Cursor IDE 的开发者交互数据 ，以强化代码生成与软件开发辅助能力100103。
xAI 的工程师坦言，这种"预训练完成后再补充加入"的方式不如初始预训练时就集成数据效果理想。下一款已启动训练的 2 万亿参数模型将在预训练之初就整合 Cursor 数据100103。
训练基础设施方面，Grok 4.5 依托 xAI 位于田纳西州孟菲斯的 Colossus 超级计算机集群 （配备 超过22万张 NVIDIA Blackwell 架构 GPU ），该集群专门针对 V9 模型进行了优化100103138。

📊 性能宣称与独立验证现状：存在显著信息缺口

马斯克在 6 月 28 日的 X 平台帖子中称，内部早期评估显示 Grok 4.5 的性能" 接近甚至可能超过 Claude Opus "101102103。但他随后澄清，并非声称 V9 在所有维度都大幅领先，而是将其定位为"与 Opus 同级别可靠的主力模型"，xAI 的近期目标是达到竞争对等水平而非明确碾压101。
⚠️ 需要重点关注的是：目前没有任何独立的第三方基准测试结果可以验证这些宣称。
  • 内部评估仅由 SpaceX 和 Tesla 工程师完成，没有第三方参与100103
  • xAI 至今未将任何 Grok 系列模型提交至主流的独立第三方排行榜（如 LMArena、Artificial Analysis Intelligence Index、SWE-bench Verified、Humanity's Last Exam）进行公开评分100103
  • 当前公开的 Grok 4.3 模型本身也缺乏来自公认评估机构的公开验证分数103
  • 马斯克宣称所对比的"Claude Opus"具体版本不明确，评估数据集和方法均未公开披露103
背景参照 ：较早的窄口径模型 grok-code-fast-1 在 SWE-bench Verified 上得分 70.8%，而竞品 Claude Opus 4.7 的 Claude Code 得分为 87.6%，两者差距约 16.8 个百分点——但这个数据并非 Grok 4.5 实测结果100。

🚀 战略背景：xAI 激进"月更"计划与七模型并行训练

Grok 4.5 的推出并非孤立事件，而是 xAI/SpaceXAI 整体激进战略的一环：

📆 月度发布计划 ：马斯克宣布，SpaceX 计划在 2026 年剩余时间内，每月发布一款完全从零开始训练的全新 AI 模型 ，而非仅在既有模型上微调或升级99100101。这种每月的全新基础模型发布节奏在前沿 AI 实验室中尚无先例103。
🔬 七模型并行训练 ：xAI 目前在 Colossus 2 集群上同时训练 7 个模型 ，涵盖 Grok 4.x 系列、Grok 5 变体以及 Imagine V2 视频模型97。Grok 5 包含 6 万亿和 10 万亿参数两个变体，均在训练中，马斯克声称 Grok 5 将达到"与通用人工智能难以区分的水平"97。
🛠️ 技术栈重构 ：马斯克透露，xAI 正在将训练和推理系统 重写为 C 和 C++ ，删除多个软件层以简化整体架构，并针对 NVIDIA GB300 AI 平台进行优化，预计约 3 个月后 将获得"真正巨大的提升"101。
🔗 生态整合 ：SpaceX 在 2026 年 6 月与 AI 编程工具 Cursor 签署了价值 600 亿美元 的全股票收购协议，预计 2026 年第三季度完成交割，Grok 4.5 是首批整合 Cursor 工作流数据的模型100103138。

⚔️ 2026年7月AI战场：一日三国杀

2026年7月9日将成为 AI 领域具有标志性意义的一天：

AnthropicClaude Fable 5（已于 7 月 1 日面向合格用户重新推出）7月1日136
Google DeepMindGemini 3.5 Pro（目标 7 月 17 日）7月17日109
在这样一个模型扎堆发布的窗口期，Grok 4.5 能否兑现其"Opus 级别、更快、更便宜"的承诺，将很快接受全球用户和开发者的实际检验136138。

⚖️ 信息置信度评估与争议点

✅ 高置信度（多源一致证实）

  • Grok 4.5 于 6 月 28 日进入 SpaceX/Tesla 私测，7 月 8 日宣布 7 月 9 日公开发布
  • 基于 1.5 万亿参数 V9 基础模型，引入 Cursor 数据补充训练
  • 马斯克定位其为"Opus 级别"，强调更快/更省/更低成本
  • SpaceXAI 计划 2026 年内每月推出全新从零训练的模型
  • 同日 OpenAI 将发布 GPT-5.6 Sol

⚠️ 需谨慎对待（证据不足/来源单薄）

  • 性能宣称缺乏独立验证 ：所有"接近/超越 Opus"的宣称均为 SpaceX/Tesla 内部自评，无任何第三方基准测试背书，学界和业界普遍持观望态度100103
  • "Opus 级别"对标对象模糊 ：未指明对应的 Claude Opus 具体版本，且 Anthropic 的模型已迭代至 Opus 4.8 和 Fable 5103136
  • 延迟记录 ：Grok 4.5 原计划 2026 年 5 月底发布，实际推迟约一个月；此前 Grok 4.4 同样延迟，xAI 存在自定发布计划未如期兑现的记录98100
  • 月更计划可行性存疑 ：每月从零训练全新基础模型的节奏史无前例，且 xAI 此前有错过自定日期的历史，该计划的可信度有待时间验证100103
  • 公开发布定价与订阅分层待公布 ：截至 7 月 8 日，尚未公布 Grok 4.5 的具体 API 定价和订阅方案，相关细节预计发布当日披露136

❓ 尚未确认的关键信息

  • 公开发布后的具体可用渠道（X Premium+、Grok App、API 全开放？）
  • 定价方案与当前 Grok 4.3 定价体系的关系
  • 上下文窗口大小、多模态能力等核心技术参数
  • 公开发布时是否附带首次独立第三方基准测试

💡 小结与展望

Grok 4.5 的公开上线标志着 xAI/SpaceXAI "月更"激进战略的正式启动 ，也意味着马斯克正以前所未有的节奏投入 AI 竞赛。选择与 OpenAI 的 GPT-5.6 Sol 同日发布，虽有"抢戏"之意，但模型最终的真实实力才是决定成败的关键。由于缺乏独立第三方验证， GroK 4.5 的实际表现仍有待 7 月 9 日上线后接受全球用户的检验 。同时，其对标 Claude Opus 的定位、Cursor 编码数据的加持效果，以及每月一更能否持续兑现，都将是未来数月 AI 领域值得密切关注的焦点。
