Connect your AI client via MCP
Endpoint (paste into an MCP client — anonymous, free, no key)
https://mcp.koalcheck.com/mcp
Or copy this and send it to your AI to set it up:

Add the "koalcheck" MCP server to my client and connect. It is a remote Streamable-HTTP server at https://mcp.koalcheck.com/mcp — connect anonymously, no API key or login needed (the free tools work right away). If my client supports a remote/HTTP MCP server directly, just use that URL. If my client config only accepts a local command (e.g. Claude Desktop's mcpServers, which rejects a bare "url"), bridge it with command "npx" and args ["-y","mcp-remote","https://mcp.koalcheck.com/mcp"]. Then tell me to fully restart the client, and list the koalcheck tools you can call. It provides US-equity research tools built on an analyst track-record engine (who has actually been right, priced vs SPY, cross-checked with SEC & FINRA).

看來中國 AI 晶片正在漲價,而且幅度不小。 部分 AI accelerator 報價相較兩個月前上漲約 20%–50%;Cambricon 下一代 690 據消息人士稱,也把價格往上調約 20%–30%,MetaX、Iluvatar CoreX 也有類似調整。 現在中國 AI 晶片面臨的問題,不只是「能不能設計出 NVIDIA 替代品」,而是設計得出來之後,有沒有足夠的 HBM 可以把它大量做出來,而且成本是多少? 所以HBM 正在成為中國 AI 國產替代的一個 bottleneck。 自從美國在 2024 年 12 月加強部分先進 HBM 對中國的出口限制後,中國晶片公司愈來愈依賴灰色市場取得供應,而且這類 HBM 的價格可能是中國以外買家的數倍。 北京希望NVIDIA → Domestic AI accelerators,但國產 AI accelerator 同樣需要 Compute die + HBM + Advanced Packaging + Networking。所以換掉 NVIDIA GPU,並不代表 Memory Wall 消失。 反而可能變成 GPU 國產化了,但 HBM 還是卡住。 這對 $MU、SK Hynix、Samsung 的長期需求訊號仍然偏正面。 因為全球 HBM 需求不是只有 NVIDIA、AMD、Google、Amazon、Meta 在搶。中國自己的 Huawei、Cambricon、MetaX 等 AI accelerator 生態,也在增加對高頻寬記憶體的需求。 AI accelerator competition 不一定降低 HBM demand,反而可能擴大 HBM 的客戶基礎。 NVIDIA 做更多 GPU,需要 HBM。 ASIC 做更多,需要 HBM。 中國國產 AI accelerator 做更多,還是需要高頻寬
