最近,NEAR founder @ilblackdragon 将亮相英伟达 AI 大会的消息,让 NEAR 公链赚足了眼球,市场价格走势也喜人。不少朋友疑惑,NEAR 链不是 All in 在做链抽象么,怎么莫名其妙就成了 AI 头部公链了?接下来,分享下我的观察,顺带科普下一些 AI 模型训练知识:

1)NEAR 创始人 Illia Polosukhin 有过较长时间的 AI 背景,是 Transformer 架构的共同构建者。而 Transformer 架构是如今 LLMs 大型语言模型训练 ChatGPT 的基础架构,足以证明 NEAR 老板在成立 NEAR 前确实有 AI 大模型系统的创建和领导经验。

2)NRAR 曾在 NEARCON 2023 上推出过 NEAR Tasks,目标是为了进行人工智能模型的的训练和改进,简单来说,模型训练需求方(Vendor)可以在平台发布任务请求,并上传基础数据素材,用户(Tasker)可以参与进行任务答题,为数据进行文本标注和图像识别等人工操作。任务完成后,平台会给用户 NEAR 代币奖励,而这些经过人工标注的数据会被用于训练相应的 AI 模型。

比如:AI 模型需要提高识别图片中物体的能力,Vendor 可以将大量图片中带有不同物体的原始图片上传到 Tasks 平台,然后用户手动标注图片上上物体位置,就可以生成大量「图片 - 物体位置」的数据,AI 就可以用这些数据来自主学习来提高图片识别能力。

乍一听,NEAR Tasks 不就是想社会化人工工程来为 AI 模型做基础服务嘛,真有那么重要?在此加一点关于 AI 模型的科普知识。

通常情况下,一次完整的 AI 模型训练,包括数据采集、数据预处理和标注、模型设计与训练、模型调优、微调、模型验证测试、模型部署、模型监控与更新等等过程,其中数据标注和预处理为人工部分,而模型训练与优化为机器部分。

显然,大部分人理解中的机器部分要明显大于人工部分,毕竟显得更高科技一些,但实际情况下,人工标注在整个模型训练中至关重要。

人工标注可以为图像中的对象(人、地点、事物)等添加标签,供计算机提升视觉模型学习;人工标注还能将语音中的内容转化为文本,并标注特定音节、单词短语等帮助计算机进行语音识别模型训练;人工标注还可以给文本添加一些快乐、悲伤、愤怒等情感标签,让人工智能增强情感分析技能等等。

不难看出,人工标注是机器开展深度学习模型的基础,没有高质量的标注数据,模型就无法高效学习,如果标注数据量不够大,模型性能也会受到限制。

目前,AI 微创领域有很多基于 ChatGPT 大模型进行二次微调或专项训练的垂直方向,本质上都是在 OpenAI 的数据基础上,额外增加新的数据源尤其是人工标注数据来施展模型训练。

比如,医疗公司想基于医学影像 AI 做模型训练,为医院提供一套在线 AI 问诊服务,只需要将大量的原始医学影像数据上传到 Task 平台,然后让用户去标注并完成任务,就产生了人工标注数据,再将这些数据对 ChatGPT 大模型进行微调和优化,就会让这个通用 AI 工具变成垂直领域的专家。

不过,NEAR 仅仅凭借 Tasks 平台,就想成为 AI 公链龙头显然还不够,NEAR 其实还在生态系统中进行 AI Agent 服务,用来自动执行用户一切链上行为和操作,用户只需授权就可以自由在市场中买卖资产。这有点类似 Intent-centric,用 AI 自动化执行来提升用户链上交互体验。除此之外,NEAR 强大的 DA 能力可以让它在 AI 数据来源的可追溯性上发挥作用,追踪 AI 模型训练数据有效性和真实性。

总之,背靠高性能的链功能,NEAR 做 AI 方向的技术延展和叙事引导,似乎要比纯链抽象要不明觉厉多了。

半个月前我在分析 NRAR 链抽象时,就看到了 NEAR 链性能 + 团队超强 web2 资源整合能力的优势,万万没想到,链抽象还没有普及开来摘到果子,这一波 AI 赋能再一次把想象力放大了。

Note:长期关注还是得看 NEAR 在「链抽象」上的布局和产品推进,AI 会是个不错的加分项和牛市催化剂!

Report Interpretation: J.P. Morgan Details Micron's Pre-Earnings Sentiment, Current Hardware Sector Dynamics

Morgan Stanley analyst Joshua Meyers' report (June 21, 2026) highlights key trends in the hardware and semiconductor sector ahead of Micron's earnings. The core takeaways are: 1. **Micron & Memory:** Memory remains a high-conviction long theme, driven by strong AI demand and rising ASPs. However, investor focus is shifting to the sustainability of Micron's >80% gross margins and the specifics of potential new long-term supply agreements (SCAs). 2. **Hardware Supply Chain:** AI-related demand for servers, networking, and storage remains robust, but company performance is diverging. Celestica (CLS) shows improved margin confidence, Western Digital and Seagate benefit from pricing, Fabrinet (FN) sees predictable AI optics growth, and Teradyne (TER) anticipates a new Google customer. 3. **AI Capex & WFE Forecasts:** JPMorgan increased its Wafer Fab Equipment (WFE) market growth forecasts to 28% in 2026 and 29% in 2027. AI infrastructure financing is evolving, with higher project-level debt reducing constraints on capex expansion. The report signals that while the AI-driven hardware cycle is strong, the market is entering a phase focused on execution verification (e.g., Micron's SCA details, Fabrinet's ramp with Amazon) and valuation sustainability. Key near-term signals include Micron's guidance, Arista Networks' outlook, and the pace of demand normalization post potential tariff-related pull-ins.

Research Report Analysis: The Fed's New Chair's Debut – New Leader, But Same Script?

Report Analysis: Federal Reserve's New Chair Debut – A New Captain, But the Same Script? Morgan Stanley's chief global economist Seth B. Carpenter analyzes the first FOMC meeting under new Fed Chair Kevin Warsh in a June 21 report. Warsh deliberately avoided providing forward guidance on interest rates, aligning with his philosophy. However, market expectations for a rate hike this year were reinforced. Key signals lie elsewhere: inflation may fall more than expected, and quantitative tightening (QT) could be more aggressive than anticipated. The FOMC's "dot plot" suggests only one rate hike in 2026. Carpenter argues that if inflation undershoots forecasts, the logic for even a single hike weakens, especially as projections indicate potential rate cuts in 2027. On QT, Warsh's stance is clear. Carpenter notes that measures like halving the Treasury's account balance could shrink the Fed's balance sheet by around $500 billion with minimal market impact. Combined with adjustments to reserve interest and liquidity rules, the ultimate QT scale may exceed expectations, though its market effect might be less disruptive unless the Fed actively sells Mortgage-Backed Securities (MBS). While Warsh initiated a review of the Fed's policy framework, the 2% inflation target remains intact for now. The report concludes that the market may be overestimating the significance of reduced forward guidance and the near-term rate hike risk, while potentially underestimating the scope and manageable nature of the coming balance sheet reduction. The key debates will hinge on upcoming core PCE data, the specifics of the QT path, and the framework review's findings.

Critical Game Week: BTC Retracement Confirmation vs. HYPE Support Battle | Guest Analysis

This weekly analysis outlines a critical juncture for BTC and HYPE markets, focusing on key price level confirmations. **BTC Analysis:** BTC is at a pivotal point after a five-wave rally from the June 5th low of $59,100. The price has broken below a short-term rising channel's lower boundary, with the current move seen as a pullback to test this breakdown. Failure to reclaim this level could lead to a retest of the $59,000-$60,000 support zone. The core scenario hinges on this channel retest outcome. * **Key Levels:** Resistance at $64,500-$65,000 (channel boundary) and $69,500-$70,500. Support at $59,000-$60,000 and $55,000. * **Strategy:** A core bearish stance is maintained (20% short from last week), with short-term plans for tactical trades. Three detailed contingency plans (A/B/C) are provided for short positions on resistance tests or breakdowns, emphasizing strict stop-loss discipline. **HYPE Analysis:** HYPE shows strong momentum but is currently in a corrective phase after hitting a new high of $76.94. The price is retesting the crucial $64-$66 support area. * **Key Levels:** Resistance near $77 and $80-$82. Support at $64-$66 and $52-$54. * **Strategy:** The short-term approach is "buy on dips, avoid chasing rallies." A long position is considered only if clear stabilization signals appear at the $64-$66 or deeper $52-$54 support zones, with tight risk controls. **General Risk Management:** A standardized trailing stop-loss protocol is emphasized: set initial stop, breakeven at +1% profit, then trail stops upward to lock in gains. *Disclaimer: All analysis is presented as a personal trading framework, not investment advice. Market conditions are complex and require dynamic adjustment.*
