Developers can access Claude Opus 4.1 through multiple channels, providing flexibility for different use cases and integration requirements. For direct interaction and testing, the model is available to all paid Claude users through the web interface, including Pro, Max, Team, and Enterprise subscribers. It’s also integrated into Claude Code, Anthropic’s command-line tool for agentic coding tasks, allowing developers to delegate complex programming work directly from their terminal environment.
For programmatic access and integration into applications, Claude Opus 4.1 is available through the Anthropic API using the model identifier claude-opus-4-1-20250805. This direct API access gives developers fine-grained control over the model’s hybrid reasoning capabilities, including the ability to manage thinking budgets for optimal cost and performance balance. The API maintains the same pricing structure as Opus 4, starting at $15 per million input tokens and $75 per million output tokens, with significant cost savings available through prompt caching (up to 90%) and batch processing (50% savings).
Additionally, enterprise developers can access Claude Opus 4.1 through major cloud platforms, specifically Amazon Bedrock and Google Cloud’s Vertex AI. This multi-cloud availability ensures that organizations can integrate the model into their existing infrastructure regardless of their preferred cloud provider. The consistent pricing across all platforms and the immediate availability without waitlists make it straightforward for development teams to upgrade from Opus 4 to Opus 4.1 and start leveraging the improved coding, research, and agentic capabilities in their projects.
