xAI 发布 Grok 4.5
Recommended because
This is worth tracking because it is a concrete model capability signal, not just a passing headline. The original source is useful for validating the details behind the headline. For builders and operators, "Introducing Grok 4.5 Jul 8， 2026 # Introducing Grok 4.5 Grok 4.5 is SpaceXAI's smartest model built for coding， agentic tasks， and knowledge work. Read More" can be used as a checkpoint for model selection, product roadmaps, eval planning, and timing decisions. I keep this thread indexed so future searches around AI model updates, capability shifts, and developer adoption can land on a source-linked page instead of disappearing into a fast-moving feed from x.ai.
What to take from this signal
Context
"Introducing Grok 4.5 Jul 8， 2026 # Introducing Grok 4.5 Grok 4.5 is SpaceXAI's smartest model built for coding， agentic tasks， and knowledge work. Read More" is archived here as a source-linked AI signal from x.ai. The useful part is the connection between Introducing, Grok, Jul, 2026, SpaceXAI and model selection, product roadmaps, eval planning, and timing decisions, which makes the item more actionable than a normal feed headline. The source context says: xAI 今日推出 Grok 4.5，为其最强模型，专为编程、智能体任务和知识工作打造。模型训练于数万块 NVIDIA GB300 GPU，DeepSWE 1.0 得分 62.0%，DeepSWE 1.1 得分 53%，Terminal Bench 2.1 得分 83.3%，SWE Bench Pro 解决率 64.7%。服务速度 80 TPS，token 效率约为 Opus 4.8 （max） 的 4.2 倍，在 Harvey Legal Agent Benchmark 排名第一。定价 $2/百万输入 token、$6/百万输出 token。即日起在 Grok Build、Cursor 和 SpaceXAI API 可用，欧盟地区预计 7 月中旬上线。
Builder takeaway
For an AI builder, the main takeaway is to watch how this signal changes practical decisions around model quality, latency, cost, eval coverage, and release timing. It can inform what to test next, which product surface to compare, and whether the underlying workflow is ready for real users.
Source context
x.ai remains the authoritative source for the original claim. This page adds a stable archive URL, a short builder interpretation, and related search language so the item can be found later when the original feed has moved on.
