Claude Sonnet 4.5 Arrives: DecentralGPT Adds Anthropic’s Long-Run Coding Model—and the “Sonnet Thinking” Deep-Reasoning Variant

What’s new in the model world

Anthropic announced Claude Sonnet 4.5—positioned as its strongest coding model to date, designed for long-running agentic workflows (reports cite 30+ hours of autonomous coding on complex tasks), and upgraded computer use performance. A companion variant, Claude 4.5 Sonnet Thinking, focuses on deeper step-wise reasoning.

Highlights commonly cited in coverage and docs include:

• Competitive results on SWE-bench for real-world software tasks.

• Big gains on OSWorld for computer-use tasks (browser, spreadsheets, file ops).

• New developer tooling (VS Code extension, checkpoints, memory tools, and Claude Agent SDK) to keep agents focused over long sessions.

• API availability as claude-sonnet-4-5, with pricing aligned to the Sonnet 4 series.

What’s live on DecentralGPT

Starting today, DecentralGPT supports:

• Claude 4.5 Sonnet (Anthropic) — strongest coding/general Sonnet.

• Claude 4.5 Sonnet Thinking (Anthropic) — deeper chain-of-thought style reasoning.

• Lower perceived latency: Regional routing brings inference closer to users, so V3.2-Exp’s efficiency gains translate into snappier responses.

You can use both inside DeGPT (consumer chat) and via our API, served on our decentralized GPU backbone with regional routing (e.g., USA / Singapore / Korea). That means snappier responses and steadier costs for teams that ship globally.

Why pair Claude 4.5 with a decentralized inference layer

• Latency your users can feel: We route requests to nearby regional nodes, so all those coding/agentic gains translate to speed in the UI, not just benchmark charts.

• Vendor-agnostic resilience: Avoid single-provider bottlenecks. Our network spans heterogeneous GPU suppliers so you can keep shipping during supply swings.

• Vendor-agnostic resilience: Run workloads across heterogeneous providers and regions—no single-vendor choke points.

• Production-ready ops: Log calls, enforce region policies, and mix Sonnet 4.5 with other models (Qwen, DeepSeek, etc.) in one routing policy.

• Web2 + Web3 friendly: Standard accounts for Web2 users; wallet-aware flows for Web3 users—same endpoints, same UX.

What you can build—right now

• Long-run coding agents that keep context, checkpoint progress, and edit repositories over hours or days.

• Enterprise copilots with spreadsheet/document creation, browser automation, and traceable audit logs.

• Ops & support bots that open tickets, fill forms, and summarize knowledge bases using regional endpoints for low latency.

• Research assistants that sustain deep multi-step reasoning with Sonnet Thinking while staying cost-predictable.

Quick start

• DeGPT (B2C): open DeGPT → select Claude 4.5 Sonnet or Claude 4.5 Sonnet Thinking → chat.

• API (B2B): set model=claude-4-5-sonnet or model=claude-4-5-sonnet-thinking, choose a region (USA/SG/KR), and stream outputs. Keep other models as fallbacks without changing your app flow.

The takeaway

Claude Sonnet 4.5 pushes practical capabilities—coding stamina, computer use, and careful reasoning. DecentralGPT turns those gains into real-world speed and reliability with regional, decentralized inference. If you’re ready to scale agents and complex workflows beyond demo territory, this combo is built for it.
