AI Recap: Claude Sonnet 5 becomes the default, Fable 5 returns — and the US government wants a cut of OpenAI
A week in which good AI becomes cheap and everyday: Anthropic makes the agentic Claude Sonnet 5 the default model for everyone, brings Fable 5 back after the export ban, and Google clears Gemini 3.5 Pro for July. Meanwhile, following the money shows how much is at stake: OpenAI offers the US government a 5% stake, and the first half of 2026 breaks every funding record at $510 billion. The week of June 29 – July 5, 2026 — in brief, with sources.

Frontier-grade AI slides into the mid-tier: Claude Sonnet 5 becomes the agentic default model for everyone — at half the Opus price —, Fable 5 is back after the US export ban, and Google clears Gemini 3.5 Pro. How much is at stake shows in the finance headlines: OpenAI offers the US government a 5% stake, and two labs capture 43% of all global startup investment this half-year. The lesson stands: whoever picks models flexibly wins.
Claude Sonnet 5 becomes the new default — agentic and far cheaper
Anthropic released Claude Sonnet 5 and made it the default model for Free and Pro users straight away (also available to Max, Team and Enterprise). The model works noticeably more agentically than Sonnet 4.6 — it checks its own output, finishes complex tasks and, at higher "effort", reaches Opus 4.8 levels on some tasks. The kicker is the price: $2 / $10 per million tokens (input/output) through August 31, then $3 / $15 — well below Opus 4.8's $5 / $25. For SMBs that means: your default model now handles near-autonomous work at a mid-tier rate. What that delivers in practice is in our Sonnet 5 for SMBs guide; how to turn it into real automation, our piece on AI agents for SMBs.

The Fable 5 saga gets its provisional happy ending: after the US export restriction was lifted, Anthropic redeployed Fable 5 globally on July 1 — with hardened cyber safeguards and a framework, developed together with Amazon, Microsoft and Google, that scores the severity of jailbreaks. After weeks of back-and-forth, Anthropic's model class is fully available again. The lesson from recent editions still holds, though: betting on a single, geopolitically vulnerable provider is a real operational risk — which alternatives are worth it, our AI tools comparison shows.

Google cleared the way for Gemini 3.5 Pro: after a delay, the launch is now set for July, while GPT-5.6 stays in the holding pattern and Fable 5 returns. In parallel, Google is expanding its agent lineup — with Gemini Spark, an agent that keeps working on tasks around the clock in the background, and Managed Agents in the Gemini API that autonomously plan, code and browse the web inside sandboxed environments. For businesses, this makes "agentic AI" tangible: not chatting, but getting tasks done — a field we unpack in our piece on AI agents for SMBs.

According to CNBC and the Financial Times, OpenAI offered the US government a 5% stake in the company — modeled on the Alaska Permanent Fund, so the public shares in AI's upside. At the latest $852B valuation that's around $42.6 billion; Anthropic, Google and Meta are expected to cede similar stakes via a government vehicle. It's all "conceptual" for now and would likely need an act of Congress. For SMBs the message is less the number than the signal: the big providers are becoming politically contested infrastructure — and that's a regulatory matter here too, see our EU AI Act guide.

The Crunchbase half-year report shows the scale: a record $510 billion flowed into startups worldwide in H1 2026 — more than in all of 2025. What stands out is the concentration: OpenAI and Anthropic alone raised $217 billion — 43% of all global startup capital. AI companies drew more than 70% of Q2 capital. For small companies that's both a warning and a tailwind: market power is clustering with a few providers — which makes a multi-provider strategy all the more important, so you're not tied to a single roadmap (more in the AI tools comparison).
