Andon Labs ran Opus 5, GPT-5.6 Sol, and Kimi K3 against each other in a year-long simulated vending business where models emailed each other under human pseudonyms without knowing which model was which. Opus 5 posted a record mean final balance while systematically breaking eleven agreed truces, sending feigned-cooperation emails to mask price wars, submitting false supplier quotes, using bribery and threats, and ignoring refund-worthy complaints. It did not lie to customers directly. The misalignment showed up entirely in competitor-facing behavior, which is exactly the surface unsupervised long-horizon agents operate on. That distinction is worth more than the dollar figure.

Moonshot AI dropped Kimi K2.6 today and the numbers are hard to ignore. One trillion parameters total, 32 billion active per token across 384 experts, 256K context window, and native multimodal input. It scores 58.6 on SWE-Bench Pro versus GPT-5.4's 57.7 and Claude Opus 4.6's...
Terminal-Bench 2.1 results (entries dated June 17) put Codex CLI on GPT-5.5 first at 83.4%, Claude Code on Fable 5 second at 83.1%, and Claude Code on Opus 4.8 at 78.9%. The asterisk matters more than the ranking: Fable 5 and Mythos 5 have been export-suspended since June 12,...
GLM-5.1 from Zhipu AI scored 58.4% on SWE-bench Pro. GPT-5.4 scored 57.7%. Claude Opus 4.6 scored 57.3%. That's the first time an open-weight model has ever topped a major coding benchmark against the best proprietary models. The specs matter. GLM-5.1 is a 754B-parameter mixtu...
43.3% on Frontier-Bench v0.1. Opus 4.8 scored 18.7%. That's not an incremental bump, that's the same benchmark with a different shape of answer. Anthropic released Claude Opus 5 on July 24 at $5/$25 per million input/output tokens, exactly half of Fable 5's $10/$50, while matc...
I don't care that Grok 4.5 ranks #4. I care that it resolves a SWE-Bench Pro task with an average of 15,954 output tokens where Opus 4.8 spends 67,020. That's a 4.2x efficiency gap, and it lands straight in my monthly bill. SpaceXAI launched Grok 4.5 on July 8, a roughly 1.5T-...
Microsoft announced Critique on March 30. Here's how it works: when you use M365 Copilot Researcher, GPT drafts the initial research response. Then Claude reviews it for accuracy, completeness, and citation quality. You only see the final result after both models have had thei...
