OpenAI has officially launched GPT-6.1 Terra, a new mid-tier model that significantly boosts intelligence while drastically reducing inference costs. The model scores 6-13 points higher than its predecessor on the Artificial Analysis Intelligence Index but costs only one-third per task ($0.40 vs $1.40). Its API pricing is highly competitive, with input/output token prices halved to $1/$5 per million and cache read costs reduced by 75%, setting a new benchmark for cost-performance.

Cross-verified reports highlight enhanced visual reasoning and Computer Use capabilities. GPT-6.1 Terra achieves ~60% on the Agents' Last Exam benchmark, matching flagship GPT-6 Astra performance at one-tenth the token cost. It supports a 1.05M context window, executes tasks over 3x faster, and sets new records in coding agent benchmarks like Terminal-Bench, achieving Pareto optimality in low-to-mid intensity reasoning.

This release profoundly impacts the developer ecosystem. Now available via ChatGPT Work, Codex, OpenRouter, and Agent Arena, it offers a low-cost solution for high-throughput automation workflows such as invoice processing and form filling. By bridging the gap between premium and lightweight models, GPT-6.1 Terra enables scalable commercial deployment of complex agentic tasks, lowering barriers to AI application adoption.

LATEST/GPT-6.1 Terra is now live on OpenRouter and Agent Arena, supporting real-time long-horizon agentic testing. It matches GPT-6 Astra's performance on Agents' Last Exam at one-tenth the cost with 3x faster execution, rapidly becoming the preferred model for automated workflows.
