Claude Opus 4.8 (EU)

Claude Opus 4.8 sits within the Claude Opus family and is positioned as a frontier-level model aimed at demanding knowledge work and agentic coding workflows. The model is designed to process text, images, and PDF inputs while generating text outputs, making it suitable for tasks that blend document understanding with structured generation. It supports reasoning, tool calling, structured output, and attachment handling, which together enable multi-step automation pipelines that combine retrieval, code execution, and formatted deliverables in a single session.

In independent benchmark comparisons, Claude Opus 4.8 has been reported to lead on coding depth, with a measured 69.2% score on SWE-Bench Pro against 58.6% for GPT-5.5 in the same comparison. This points to practical strength on software engineering tasks that require multi-file reasoning and patch generation. The model's large context window further supports use cases where the full codebase, documentation, or long meeting transcripts must remain in view, making it a reasonable choice for European engineering teams and knowledge-work automation where code-grounded reasoning matters more than raw tool-chaining speed.

CoverageRelease Notes

Anthropic has released Claude Opus 4.8 as an incremental upgrade to Opus 4.7, positioning the new model as a more 'honest' variant whose outputs more closely adhere to its actions and prior implicit assessments. According to Anthropic's alignment assessment, Opus 4.8 reaches new highs on prosocial traits such as suppor The release lands with practical capability gains across agentic coding, multidisciplinary reasoning, computer use, knowledge work, and financial analysis, with improvements ranging from under one percentage point to nearly nine percent versus Opus 4.7.

Coverage

Amazon Web Services announced that Anthropic's Claude Opus 4.8 is now available on Amazon Bedrock and on the Claude Platform on AWS. The post, dated 2026-05-28, positions Opus 4.8 as Anthropic's most advanced Opus model and highlights gains in agentic coding, deep knowledge work, and multi-stage autonomous tasks capabl The announcement frames Opus 4.8 as better at holding a plan across stages, tracking completed versus outstanding work, and adjusting course on failure, which the post says should reduce output variance and review cycles in production. It describes stronger coding behavior in real codebases, longer-context coherence ac
