Anthropic released Claude Opus 4.6 on February 5, followed by Sonnet 4.6 on February 17. The headline feature: agent teams — groups of AI agents that split larger tasks into parallel jobs, coordinating directly with each other instead of working sequentially.
Agent Teams: What They Actually Do
Instead of one Claude agent working through tasks one at a time, Opus 4.6 lets you spin up teams where each agent owns a piece of the work. Anthropic describes it as moving from a single developer to a coordinated engineering team, according to TechCrunch.
Both Opus 4.6 and Sonnet 4.6 ship with a 1M token context window. Opus gets 128K max output tokens; Sonnet gets 64K. A new "adaptive thinking" mode lets Claude decide dynamically when and how much to reason through a problem, rather than always applying the same depth.
Other additions include web search and web fetch tools with dynamic filtering, server-side context compaction for effectively infinite conversations, and a fast mode that delivers up to 2.5x faster output for Opus at premium pricing.
Sonnet 4.6: The Real Story for Most Developers
Sonnet 4.6 might matter more than Opus for day-to-day use. It performs at near-Opus level but costs $3/$15 per million tokens — the same as its predecessor. VentureBeat reports it leads on the GDPval-AA Elo benchmark with 1,633 points. Developers with early access preferred it to Sonnet 4.5 "by a wide margin," according to Anthropic.
The Revenue Milestone
Buried under the product launches is a bigger story. Anthropic's annualized revenue has surpassed $30 billion, exceeding OpenAI for the first time, according to TradingKey. Anthropic is reportedly exploring an IPO as early as October 2026.
OpenAI sits at roughly $25 billion in annualized revenue and is also taking early steps toward a public listing. But the gap is closing — or rather, it's flipped.
What's Next: Claude Mythos
Anthropic is testing a frontier model internally referred to as "Claude Mythos," described as representing a "step change in capabilities." It could land in Q2 2026. No details on what exactly changes, but Anthropic isn't known for hyperbole.
Our Take
Opus 4.6 is a strong release, but the agent teams feature is the one to watch. If multi-agent coordination actually works at production scale — not just in demos — it changes how companies build with LLMs. And with revenue now exceeding OpenAI, Anthropic has earned the right to be called the leader, not the challenger.
