    TLDR

    Tev-Gym's creators say its 1,170 environments offer dense progress rewards for long-horizon agentic reinforcement learning. They report that Tev-27B matches GPT-6 Astra and Claude Opus 5 on ALE-CM, covering computing and math, at Pass@5. They also say Tev-320B tops open models on Terminal-Bench 4.0-CM at Pass@1, trailing GPT 5.6 sol by 0.02.
