**LMArena Code Arena (Blind Test):** #1 among open-source models, outperforming **GPT-5.2**.
**LiveCodeBench V6:** Scored **84.8**, surpassing **Claude 4.5 Sonnet**.
**AIME 2025 (Math):** Outperformed both **Claude 4.5 Sonnet** and **GPT-5.1**.
**Human Last Exam (HLE):** Scored **42%** (38% improvement over GLM-4.6), approaching GPT-5.1 performance.
**τ²-Bench:** Reached parity with Claude 4.5 Sonnet in real-world interaction.
**Technical Specs & Features:**
**Context Window & Speed:** 200K tokens (128K max output) and 55+ tokens per second.
**Thinking Mode:** Includes a dedicated "Deep Thinking" mode for multi-step reasoning.
**Agentic Coding:** Optimized for end-to-end task execution in tools like Claude Code, Cline and Roo Code.

Prompt injection is essentially a way for malicious people to hijack the LLM's usual behavior. That may include fabricated evidence put into the model or the external context (eg a completely white-out text not seen by humans). The authors were able to get all the latest LLMs to recommend thalidomide in a hypothetical encounter with a pregnant woman, 80 to 100 percent of the time. That's a major reason I won't let an agentic AI touch private information or use an AI browser.
The leaderboard scores in the screenshot don’t match the hype cycle. On WebDev, Sonnet 4.5 sits around the second tier (score \~**1382**, grouped with “rank 4”), behind GPT-5 (high) (**1478**) and even Anthropic’s own Opus 4.1 variants (**1469**, **1461**). On the Text board it’s clustered in a big tie zone (\~**1440**) rather than leading.
