Claude Sonnet 5: Pricing, Benchmarks & API Access (2026)

Claude Sonnet 5 is Anthropic's advanced model designed for coding, agentic tasks, vision, and tool-based workflows, positioned between the Opus 4.8 and Haiku models in terms of capabilities and cost. It features a 1 million-token context window and supports up to 128,000 output tokens, making it efficient for processing large codebases and documents. The model excels in reasoning, debugging, and multi-file tasks and offers high-resolution vision up to 2576px. Available through the Anthropic API, AWS Bedrock, Google Vertex AI, and Eden AI, Claude Sonnet 5 offers flexibility in deployment with introductory pricing of $2 per million input tokens and $10 per million output tokens, which will later increase to $3 and $15, respectively. It supports adaptive thinking and high effort levels, which are advantageous for complex workloads. The model can be integrated with existing cloud services and is suitable for tasks requiring strong reasoning without incurring the higher costs associated with the Opus model. Eden AI allows for seamless integration with other models using a unified API, facilitating cost-effective and performance-optimized routing and fallback strategies.
