Anthropic Open-Sources the Model Context Protocol (MCP)
Anthropic has released the Model Context Protocol (MCP), an open standard enabling secure, two-way connections between AI assistants and external data sources such as business tools, content repositories, and development environments. The protocol introduces a client-server architecture with SDKs, local MCP server support in Claude Desktop, and a repository of pre-built connectors for systems like GitHub, Slack, Google Drive, and Postgres. Early adopters include Block and Apollo, with development tool companies Zed, Replit, Codeium, and Sourcegraph integrating MCP into their platforms. The goal is to replace fragmented, per-source integrations with a single universal protocol, improving context availability for AI agents.
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 launches Claude 2 with 100K context window and improved coding, reasoning, and safety
Anthropic released Claude 2, featuring a 100K token context window, improved performance on coding (71.2% on Codex HumanEval, up from 56.0%), math (88.0% on GSM8k), and legal reasoning (76.5% on the Bar exam multiple choice section). The model is available via API at the same price as Claude 1.3 and through a new public beta at claude.ai for US and UK users. Safety improvements include a 2x reduction in harmful outputs on internal red-team evaluations compared to Claude 1.3. Early API partners include Jasper and Sourcegraph.
