Claude Sonnet 4 Now Generally Available in Xcode 26
Anthropic has made Claude generally available as the AI backend for Xcode 26's coding intelligence features, powered by Claude Sonnet 4. Developers can connect their Claude account to access a coding assistant with natural language interaction, documentation generation, inline edits, and SwiftUI preview creation directly within Apple's IDE. The integration is available to Claude Pro, Max, Team, and Enterprise plan subscribers who have Claude Code access. Usage limits are shared across platforms with a portion allocated to Xcode.

Apple's Xcode 26.3 Integrates Claude Agent SDK for Autonomous Coding
Xcode 26.3 introduces native integration with Anthropic's Claude Agent SDK, enabling autonomous, long-running coding tasks directly within Apple's IDE. The integration supports visual verification via Xcode Previews, full-project reasoning across Apple frameworks, autonomous task execution with goal-directed behavior, and MCP-based access for Claude Code CLI users. This expands on an earlier September announcement that brought Claude Sonnet 4 to Xcode in a limited turn-by-turn capacity, now replacing it with the same agentic harness that powers Claude Code.
Anthropic Releases Claude Sonnet 4.5: Top Coding and Computer-Use Model with Agent SDK
Anthropic has released Claude Sonnet 4.5, claiming it is the best coding model and strongest model for building complex agents, with a 61.4% score on OSWorld (up from 42.2% for Sonnet 4) and state-of-the-art performance on SWE-bench Verified. The release is accompanied by major product upgrades including checkpoints in Claude Code, a native VS Code extension, a Claude Agent SDK giving developers access to the same infrastructure powering Claude Code, and new context editing and memory tools in the Claude API. Pricing is unchanged from Sonnet 4 at $3/$15 per million input/output tokens. Early enterprise customers including Cursor, GitHub Copilot, Devin, Canva, and Figma report significant gains in coding, agentic, and long-context tasks.
Claude 3.7 Sonnet and Claude Code: Anthropic's First Hybrid Reasoning Model and Agentic Coding Tool
Anthropic has released Claude 3.7 Sonnet, described as their most capable model to date and the first hybrid reasoning model on the market, capable of operating in both standard and extended thinking modes within a single unified model. The model achieves state-of-the-art results on SWE-bench Verified and TAU-bench, with particular strength in coding and front-end web development. Alongside the model, Anthropic is launching Claude Code in limited research preview, a command-line agentic coding tool that can read/edit files, run tests, and push to GitHub. Pricing remains unchanged at $3/M input and $15/M output tokens, with availability across Claude.ai plans, Amazon Bedrock, and Google Cloud Vertex AI.
Claude 3.5 Sonnet begins rollout on GitHub Copilot via Amazon Bedrock
Anthropic's Claude 3.5 Sonnet is now rolling out on GitHub Copilot, available in public preview for all Copilot Chat users in Visual Studio Code and GitHub.com. The model claims top performance on SWE-bench Verified among publicly available models and 93.7% on HumanEval. The integration runs via Amazon Bedrock's cross-region inference and reaches GitHub's community of over 100 million developers, representing a significant distribution milestone for Claude.
Anthropic Introduces Claude Opus 4 and Sonnet 4 with Leading Coding Benchmarks and Agent Capabilities
Anthropic has released Claude Opus 4 and Claude Sonnet 4, positioning Opus 4 as the world's best coding model with 72.5% on SWE-bench and 43.2% on Terminal-bench, and Sonnet 4 at 72.7% on SWE-bench. Both models are hybrid (near-instant + extended thinking), support extended thinking with tool use in beta, parallel tool execution, and improved memory via local file access. Alongside the models, Anthropic is launching Claude Code as generally available with GitHub Actions, VS Code, and JetBrains integrations, plus four new API capabilities: code execution tool, MCP connector, Files API, and one-hour prompt caching. Pricing is unchanged from prior Opus and Sonnet tiers ($15/$75 and $3/$15 per million tokens respectively), with availability on Anthropic API, Amazon Bedrock, and Google Cloud Vertex AI.
Anthropic Releases Claude Sonnet 4.6 with 1M Token Context, Improved Computer Use, and Coding Capabilities
Anthropic has released Claude Sonnet 4.6, positioned as a major upgrade over Sonnet 4.5 with improvements across coding, computer use, long-context reasoning, and agent planning. The model features a 1M token context window in beta and is now the default on claude.ai Free and Pro plans at unchanged pricing ($3/$15 per million tokens). Notably, users preferred Sonnet 4.6 over the prior Opus 4.5 frontier model 59% of the time in coding tasks, and the model shows significant gains on OSWorld computer-use benchmarks alongside improved prompt injection resistance. Safety evaluations found no major alignment concerns and rated it as safe or safer than prior Claude models.
Claude Code 2.0: VS Code Extension, Checkpoints, and Agent SDK for Autonomous Development
Anthropic has released several major upgrades to Claude Code, including a native VS Code extension in beta, a refreshed terminal interface (version 2.0), and a checkpointing system that saves code state before each change to enable safe autonomous operation. The release also formalizes the Claude Agent SDK (formerly Claude Code SDK) with support for subagents, hooks, and background tasks, enabling parallel and long-running development workflows. Claude Sonnet 4.5 is now the default model powering Claude Code. These features collectively position Claude Code as a more capable autonomous coding agent for complex, multi-step software development tasks.
Anthropic launches Claude in Canada with full product suite
Anthropic expanded Claude's availability to Canada as of June 5, 2024, offering access to Claude.ai, the iOS app, the API, and the Team plan. Canadian users can subscribe to Claude Pro at CA$28/month for access to the Claude 3 model family (Opus, Sonnet, Haiku) with 5x usage limits. The expansion is a geographic rollout with no new technical capabilities announced.
