Claude Opus 4.8 is on Eden AI: Features, Benchmarks, and API Access

Claude Opus 4.8, Anthropic’s latest model, offers significant improvements over its predecessor, Opus 4.7, particularly in agentic coding, where it achieves a 69.2% success rate compared to 64.3% in the previous version. The model is designed for complex workflows, such as codebase migrations, legal document analysis, and enterprise knowledge work, with a 1 million token context window that allows processing large datasets in a single call. It is 4 times less likely to miss flaws in its own generated code, enhancing its utility for debugging and automated review processes. Available through Eden AI’s unified API, it maintains the same pricing as Opus 4.7 and introduces features like dynamic workflows, effort controls, and Fast Mode, which prioritizes speed over depth. Claude Opus 4.8 is the only model to complete every case end-to-end on the Super-Agent benchmark and matches GPT-5.5 on cost-adjusted performance, making it a strong choice for tasks demanding reliability and efficiency.
