Anthropic Releases Claude Sonnet 4.5 with Advanced Autonomous Coding Capabilities

Anthropic launched Claude Sonnet 4.5, a new AI model claiming state-of-the-art coding performance that can build production-ready applications autonomously. The model has demonstrated the ability to code independently for up to 30 hours, performing complex tasks like setting up databases, purchasing domains, and conducting security audits. Anthropic also claims improved AI alignment with lower rates of sycophancy and deception, along with better resistance to prompt injection attacks.

OpenAI Releases GPT-5-Codex with Dynamic Thinking Capabilities for Enhanced AI Coding

OpenAI has launched GPT-5-Codex, an upgraded version of its AI coding agent that can dynamically allocate thinking time from seconds to seven hours on coding tasks. The model demonstrates superior performance on coding benchmarks and code review tasks compared to previous versions. It's being rolled out to ChatGPT subscribers and represents OpenAI's effort to compete in the increasingly crowded AI coding tools market.

OpenAI Acquires Alex Codes Team to Strengthen AI Coding Agent Development

OpenAI has hired the team behind Alex Codes, a Y-Combinator-backed startup that created an AI coding assistant for Apple's Xcode development environment. The three-person team is joining OpenAI's Codex division to work on the company's AI coding agent, following a pattern of acqui-hires by OpenAI including the recent $1.1 billion acquisition of Statsig.

Claude Sonnet 4 Expands Context Window to 1 Million Tokens for Enterprise Coding Applications

Anthropic has increased Claude Sonnet 4's context window to 1 million tokens (750,000 words), five times its previous limit and double OpenAI's GPT-5 capacity. This enhancement targets enterprise customers, particularly AI coding platforms, allowing the model to process entire codebases and perform better on long-duration autonomous coding tasks.

OpenAI Launches Codex: Advanced AI Coding Agent Powered by o3 Reasoning Model

OpenAI has introduced Codex, a new AI coding agent powered by the codex-1 model (an optimized version of o3) that can write features, fix bugs, answer questions about codebases, and run tests in a sandboxed environment. Initially available to ChatGPT Pro, Enterprise, and Team subscribers with plans to expand access, Codex joins the competitive market of AI coding tools like Claude Code and Gemini Code Assist.

Apple and Anthropic Collaborate on AI-Powered Code Generation Platform

Apple and Anthropic are reportedly developing a "vibe-coding" platform that leverages Anthropic's Claude Sonnet model to write, edit, and test code for programmers. The system, a new version of Apple's Xcode programming software, is initially planned for internal use at Apple, with no decision yet on whether it will be publicly released.

JetBrains Releases Open Source AI Coding Model with Technical Limitations

JetBrains has released Mellum, an open AI model specialized for code completion, under the Apache 2.0 license. Trained on 4 trillion tokens and containing 4 billion parameters, the model requires fine-tuning before use and comes with explicit warnings about potential biases and security vulnerabilities in its generated code.

Microsoft Reports 20-30% of Its Code Now AI-Generated

Microsoft CEO Satya Nadella revealed that between 20% and 30% of code in the company's repositories is now written by AI, with varying success rates across programming languages. The disclosure came during a conversation with Meta CEO Mark Zuckerberg at Meta's LlamaCon conference, where Nadella also noted that Microsoft CTO Kevin Scott expects 95% of all code to be AI-generated by 2030.
