According to Ethan Mollick on X, the METR long-task score is highly correlated with multiple leading AI benchmarks, indicating it is a robust proxy for overall AI capability despite known limitations. As reported by Mollick, correlations between log(METR) and key evaluations such as coding, reasoning, and multimodal benchmarks remain strong, suggesting consistent cross-metric signal for model progress. According to Mollick, this alignment helps enterprises simplify model selection and governance by using METR as a high-level screening metric before domain-specific testing. As cited by Mollick, the finding reinforces model evaluation strategies that combine METR with targeted benchmarks to de-risk deployments in areas like agents, code generation, and tool-use.

According to God of Prompt on X, citing METR Evals, Claude Opus 4.6 achieves a 50% success rate over a 14.5-hour autonomous software work horizon, but METR reports their current software-task suite is saturated, making measurements noisy and potentially understating capability (according to METR Evals). According to METR Evals, the observed capability doubling time on real engineering tasks is approximately 123 days, implying rapid compounding gains that compress the path from basic assistance to AI-managed development pipelines. As reported by God of Prompt, updated prompt architectures and a revised Claude Mastery Guide for Opus 4.6 are already recommended to capture performance that older prompting strategies miss, highlighting immediate opportunities for teams to retool workflows, extend autonomous run windows, and design evaluation suites beyond METR’s current ceiling.

According to The Rundown AI, new METR benchmarking data indicates a sharp shortening in the time horizon of software engineering tasks that frontier AI models can complete, suggesting rapidly improving autonomy in coding workflows. As reported by METR, recent evaluations show state-of-the-art models handling longer-horizon software tasks with fewer human interventions, pointing to near-term viability for automated issue triage, multi-file refactoring, and integration test authoring in production pipelines. According to The Rundown AI, the vertical curve implies compounding gains from tool use, code execution, and repository-level context, which METR attributes to improved planning and error-recovery capabilities in models like Claude and GPT-class systems. As reported by METR, the business impact includes reduced cycle times for feature delivery, lower QA costs via automated test generation, and new opportunities for AI-first developer platforms focused on continuous code maintenance and migration.

According to Greg Brockman on Twitter, GPT5.2 has achieved state-of-the-art results in the latest METR evaluations, demonstrating significant advances in handling long-horizon tasks. As reported by Noam Brown, the linear-scale and 80% success-rate plots reveal that GPT5.2 notably outperforms previous models, signaling major progress for OpenAI in the development of advanced language models with strong long-term reasoning capabilities.
