We built TERMS-Bench, a three-tier benchmark for LLM agents in real-world economic negotiation. No LLM-as-judge, no outcome rubrics: the environment itself is the verifier. 🏆Among frontier models, @AnthropicAI Claude Opus 4.6 #1, @Zai_org GLM 5.1 #2. ✨Surprisingly strong: @GoogleDeepMind @googlegemma Gemma 4 31B — best open-weight, holds up as negotiations get harder. 🔗 terms-bench.github.io

Very honored to see Gemma @googlegemma feature TERMS-Bench! We built TERMS-Bench to evaluate LLM negotiation agents in settings where success is not cleanly verifiable by math/code-style checks, but also should not be outsourced to LLM-as-judge. Instead, the economic environment verifies the outcome. Gemma 4 31B is the top open-weight model on our benchmark, competitive alongside frontier peers. Excited to see open models advancing in these social-strategic, agentic evaluation domains 💛🚀
