Anthropic releases Claude Opus 4.7, narrowly retaking lead for most powerful generally available LLM
ThinkingNews Desk · how this was written
Anthropic has launched Claude Opus 4.7, describing it as a notable improvement over Opus 4.6 in advanced software-engineering tasks and adding a new “xhigh” effort level. The model uses an updated tokenizer that enhances text processing, though the same input may generate more tokens, and it delivers benchmark-leading coding and agentic performance, narrowly reclaiming the lead as the most powerful generally available large language model.
