Anthropic bringt „ehrlicheres“ Claude Opus 4.8 – und kündigt Mythos an
Anthropic released Claude Opus 4.8 on 2026-05-29. Benchmarks improved (e.g., SWE-Bench Pro 69.2%, Terminal-Bench 74.6%) and Databricks reported roughly 61% lower token cost versus Opus 4.7. The author highlights a practical behavioral change: Opus 4.8 is ~4x less likely than 4.7 to let code flaws pass without flagging and proactively surfaces uncertainty, which materially reduces silent failures when delegating work to agents. Product changes include Dynamic Workflows (Claude Code research preview), an effort-control knob (claude.ai / Cowork), and a Messages API improvement that accepts mid-array system entries without breaking prompt cache. Pricing remained the same for the regular tier, and a cheaper fast mode was introduced. Anthropic also announced a separate project called Mythos in its broader announcement.

AI Leaderboard Arena Raises $200M at $3.1B Valuation
Arena, the AI leaderboard platform that originated as a UC Berkeley research project, has raised a $200 million Series B round at a $3.1 billion valuation. The round was led by Lightspeed Venture Partners and Khosla Ventures, with participation from Salesforce Ventures, 01 Advisors, Dell Technologies Capital, Endeavor Catalyst, a16z, Felicis, and others. This follows the company's announcement in June that it reached $100 million in annualized run-rate revenue. Arena provides a crowdsourced platform where users rate AI model outputs, and it has introduced a commercial product called AI Evaluations to offer detailed performance analytics. The company has also added a new 'alignment' category to its leaderboard, ranking models on issues like unauthorized actions and deceptive completion. Arena's valuation has nearly doubled in about 10 months, from $1.7 billion post-money in January to $3.1 billion now.
OpenAI's revenue reportedly $20B less than projected
OpenAI has reportedly informed investors that its annualized revenue is approaching $50 billion, a figure $20 billion lower than the previously reported $70 billion. The earlier figure was based on attempts by OpenAI's own investors to compare with Anthropic's run rate. Discrepancies arise from differing calculation methods; Anthropic includes sales made by cloud partners, while OpenAI does not. OpenAI has raised substantial capital, including $122 billion in a March 2026 funding round, but its leaked 2025 financials showed revenues of $13 billion with significant spending. The company's IPO has been postponed to early 2027.
Google launches unified agentic AI for Gemini
At a Google Cloud event on Thursday, Google announced it is bringing agentic AI to its Gemini assistant, launching a unified agent that can autonomously plan and execute tasks on behalf of users. Aimed initially at businesses, the agent can connect to internal systems and external tools, use custom skills, and even choose from third-party models like Anthropic's Claude. It will have its own Workspace account with an email address, and will write its own audit trail. Early testers include On, Shopify, and PayPal. Gemini has over 1 billion monthly active users, and nearly 90% of Fortune 100 companies use Gemini Enterprise.
