Anthropic’s Claude Opus 4.7 Is Here, and It’s Already Outperforming Gemini 3.1 Pro and GPT-5

Anthropic’s just released its latest AI model, Claude Opus 4.7. The company claims it handles complex, long-running tasks with greater rigor and consistency than its predecessor, follows instructions more precisely, and can verify its own outputs before delivering a response. In short, Anthropic says the new model is a real-world productivity booster. This comes shortly after Anthropic launched Claude Opus 4.6 in February. And the model is “less broadly capable” than its most recent offering, Claude Mythos Preview. But at this time Anthropic has no plans to release Claude Mythos Preview to the general public. It says the effort is aimed at understanding how models of that caliber could eventually be deployed at scale. How Does Opus 4.7 Compare? According to The Next Web, the most striking gains are in software engineering: on SWE-bench Pro, an AI evaluation benchmark, Opus 4.7 scored 64.3 percent—up from 53.4 percent on Opus 4.6 and ahead of both GPT-5.4 at 57.7 percent and Gemini 3.1 Pro at 54.2 percent. Opus 4.7 Token Usage Users upgrading from Opus 4.6 should note two changes that affect token usage. An updated tokenizer improves how the model processes text but can increase token counts by roughly 1.0 to 1.35 times depending on content type. The model also thinks more deeply at higher effort levels, particularly in later turns of agentic tasks, which boosts reliability on complex problems but produces more output tokens. Opus 4.7 Safety Additionally, Anthropic says Opus 4.7 carries a safety profile comparable to its predecessor, with evaluations showing low rates of deception, sycophancy, and susceptibility to misuse. The company’s alignment assessment concluded that the model is “largely well-aligned and trustworthy, though not without room for improvement.” “We are releasing Opus 4.7 with safeguards that automatically detect and block requests that indicate prohibited or high-risk cybersecurity uses,” Anthropic said in a release. “What we learn from the real-world deployment of these safeguards will help us work towards our eventual goal of a broad release of Mythos-class models.” This commitment to transparency around safety is central to how Anthropic has positioned itself since its founding in 2021. Anthropic has spent much of its existence cultivating a reputation as a more safety-focused alternative. CEO Dario Amodei previously served as vice president of research at OpenAI before leaving to co-found Anthropic alongside his sister Daniela Amodei and other former OpenAI employees who shared his concerns that the company was not taking AI safety seriously enough. “We’re under an incredible amount of commercial pressure and make it even harder for ourselves because we have all this safety stuff we do that I think we do more than other companies,” Anthropic’s CEO Dario Amode said on podcaster Dwarkesh Patel’s Podcast. The upgrade represents a step forward across the capabilities that matter most to Claude’s users. “The model does not win every benchmark against every competitor, but it wins convincingly on the ones most directly tied to real-world productivity,” The Next Web said.
