As Anthropic launches Claude Opus 4.8, it raises $65B in new funding
Anthropic PBC today introduced a new large language model, Claude Opus 4.8, that’s significantly better than its predecessor at complex coding tasks.
The company announced the LLM alongside another major business milestone. Anthropic has raised $65 billion in new funding at a $965 billion valuation to buy more computing infrastructure.
The company evaluated Claude Opus 4.8’s reasoning capabilities using Terminal-Bench 2.1, a benchmark that measures LLMs’ ability to perform tasks in the command line. The model scored 74.2%, a 8.4% improvement over the 4.7 version. Opus 4.8 scored 4.9% higher on a more general-purpose coding test called SWE-Bench Pro. Additionally, Anthropic logged improvements across benchmarks that comprised computer use and financial analysis tasks.
The new model includes optimizations that enable it to detect erroneous prompt responses. According to Anthropic, it’s four times less likely than its predecessor to output faulty code without pointing out the issue. It’s also less prone to making unsupported claims and missing misuse attempts.
