The model introduces several new API capabilities: adaptive thinking mode lets Claude decide when deeper reasoning would be helpful; context compaction automatically summarises older parts of conversations to extend long-running tasks; and a four-tier effort control system gives developers granular control over intelligence, speed, and cost.
Perhaps most notably, agent teams, a research preview feature in Claude Code, enables multiple AI agents to work simultaneously on different aspects of a project, coordinating autonomously across frontend, API, and migration tasks.
OpenAI responded within twenty minutes of Anthropic's announcement by releasing GPT-5.3 Codex, scoring 77.3 percent on its own coding benchmarks. The rapid-fire releases underscore the intensifying competition for enterprise AI dominance.
Pricing sits at five dollars per million input tokens and twenty-five dollars per million output tokens, with premium rates for prompts exceeding two hundred thousand tokens. The release comes as Anthropic's Claude Code has surpassed one billion dollars in annual revenue and the company pursues a ten billion dollar funding round at a three hundred and fifty billion dollar valuation.

Microsoft has added Anthropic's Claude Opus 4.6 to its Azure Foundry platform, giving enterprise customers access to a model featuring a one million token context window and new agent teams capability. The launch triggered an immediate response from OpenAI, which released GPT-5.3 Codex just twenty minutes later.
Anthropic's Most Powerful Model Lands on Azure
Microsoft has made Anthropic's Claude Opus 4.6 available through its Foundry platform on Azure, marking a significant expansion of the model's enterprise reach. Announced on February 5, 2026, the integration allows developers to deploy the AI through Azure's serverless API using existing billing agreements, with support for Python, TypeScript, and C# SDKs alongside Microsoft Entra authentication.Breakthrough Technical Capabilities
Claude Opus 4.6 represents a major leap for Anthropic's flagship model line. For the first time, an Opus-class model features a one million token context window in beta, capable of processing roughly seven hundred and fifty thousand words in a single session. Maximum output tokens have doubled to one hundred and twenty-eight thousand.The model introduces several new API capabilities: adaptive thinking mode lets Claude decide when deeper reasoning would be helpful; context compaction automatically summarises older parts of conversations to extend long-running tasks; and a four-tier effort control system gives developers granular control over intelligence, speed, and cost.

Benchmark Dominance Sparks Rivalry
On the GDPval-AA benchmark for economically valuable knowledge work, Claude Opus 4.6 achieved an Elo rating of 1606, roughly one hundred and forty-four points ahead of OpenAI's GPT-5.2 and one hundred and ninety points above its predecessor. On Terminal-Bench 2.0 for agentic coding, the model scored 65.4 percent.OpenAI responded within twenty minutes of Anthropic's announcement by releasing GPT-5.3 Codex, scoring 77.3 percent on its own coding benchmarks.

Enterprise Adoption and Market Impact
The model is also rolling out through GitHub Copilot for Pro, Business, and Enterprise users across Visual Studio Code, Visual Studio, and GitHub Mobile. Enterprise administrators must enable the Claude Opus 4.6 policy in Copilot settings before developers can access it.Pricing sits at five dollars per million input tokens and twenty-five dollars per million output tokens, with premium rates for prompts exceeding two hundred thousand tokens.
