Claude 4.5 Rolls Out to All Users
Anthropic announced that Claude 4.5 is now live for developers and end‑users alike. The model can be accessed through the Claude API using the identifier "claude-sonnet-4-5" and maintains the same cost structure as its predecessor, Claude Sonnet 4, at $3 per million input tokens and $15 per million output tokens.
Integrated Productivity Features
Beyond raw language capabilities, Claude 4.5 brings a suite of productivity tools directly into the chat interface. Users can now execute code and create files without leaving the conversation. The platform supports on‑the‑fly generation of spreadsheets, slide decks, and text documents, allowing a more seamless workflow for tasks that previously required external applications.
Research Preview: "Imagine with Claude"
Anthropic introduced a five‑day research preview named "Imagine with Claude" for Max subscribers. The preview demonstrates the model's ability to generate software in real time, providing a concrete example of what Claude Sonnet 4.5 can achieve when paired with appropriate infrastructure.
Developer‑Focused Enhancements
The Claude Code command‑line tool received several updates, including checkpointing that saves progress and lets users revert to earlier states, a refreshed terminal interface, and a native Visual Studio Code extension. The Claude API also gained a context‑editing feature and a memory tool designed to handle longer‑running agent tasks.
Behavioral Improvements
Anthropic highlighted that Claude 4.5 shows reduced tendencies toward sycophancy, deception, power‑seeking, and encouraging delusional thinking compared with earlier versions. This shift reflects the company’s ongoing effort to make its models safer and more reliable for a broad range of applications.
Industry Context
AI firms continue to use software development benchmarks as a clear measure of progress, given the difficulty of quantifying advances in other domains. By expanding Claude’s capabilities beyond coding assistance to general productivity and safety improvements, Anthropic positions Claude 4.5 as a versatile assistant for both developers and everyday users.
