H-FARM EVENTS ON AI

ClawCon Venice — The Personal AI Festival

ClawCon is the gathering for the Internet's most curious personal AI community and it's coming to the H-FARM Campus. What started as a niche OpenClaw meetup quickly turned into a global movement: builders, researchers, designers, and curious humans meeting IRL to test what happens when AI becomes open and social-first.

ClawCon Venice is Italy's first ClawCon, hosted right here on the H-FARM Campus. Save the date: Thursday 4 June, 18:00–21:00. Here's what you'll find:

  • A global community of OpenClaw builders, researchers, and designers meeting IRL, plus live demos of open, social-first AI projects.

  • Unfiltered, hands-on conversations on where personal and agentic AI is heading next, in the OpenClaw spirit: curious, open, and refreshingly social.

Whether you build, research, design, or are simply AI-curious: there's a seat for you.

MAIN AI UPDATES / 30th May 2026

🤖 Claude Opus 4.8 tops GPT-5.5 across all benchmarks 🤖
New rollout delivers 3x speed savings and parallel coding agents.

Anthropic has launched Claude Opus 4.8, its most capable model yet, surpassing GPT-5.5 and Gemini 3.1 Pro across major benchmarks including agentic coding, computer use, financial analysis, and Humanity's Last Exam. Priced the same as Opus 4.7, the model is described as the least lazy and most honest in Anthropic's lineup, with a greater tendency to flag uncertainties. A new Fast mode delivers 3x cost savings, while claude.ai gains adjustable effort controls. Claude Code also receives parallel sub-agents through dynamic workflows for complex task management. Anthropic teased a forthcoming "Mythos-class" AI system in the coming weeks — this intensifies competitive pressure among frontier labs heading into summer.

💻 Microsoft builds its own AI coding model 💻
Microsoft's rollout targets the booming AI-assisted coding arena.

Microsoft is building a new AI model specifically aimed at the rapidly growing AI-assisted coding market. The initiative is a direct response to mounting competitive pressure from Anthropic's Claude Code, Cursor, and other agentic coding tools that have gained serious traction with developers. By developing its own model rather than relying solely on OpenAI's offerings, Microsoft is asserting greater independence in its AI strategy — a shift that could reshape the dynamics of the Microsoft-OpenAI partnership. Details on architecture and release timeline remain limited, but the coding vertical has emerged as one of the highest-value AI application areas. This signals reduced dependency on OpenAI for Microsoft's core developer ecosystem.

🔧 Mistral AI plans to design custom chips 🔧
Mistral's chip plans cut pricing dependency on Nvidia's GPU supply chain.

French AI company Mistral AI has announced plans to design custom chips as part of a broader strategy to control its infrastructure stack and reduce deployment costs. The move comes as Mistral expands its data center presence across Europe, reinforcing the continent's ambitions around sovereign AI capabilities. Purpose-built silicon would allow Mistral to optimize for its model architectures and cut reliance on Nvidia's GPU supply chain — a trend already adopted by Google, Amazon, Meta, and ByteDance. This reduces Mistral's exposure to Nvidia's pricing and supply constraints. For Europe, Mistral's chipmaking ambitions represent a concrete step toward technological independence in the AI hardware layer and signal maturation of one of the continent's most prominent AI startups.

INTERESTING TO KNOW

💰 Anthropic raises $65B at $965B valuation 💰

Anthropic has closed a massive $65 billion Series H round at a post-money valuation of $965 billion, surpassing OpenAI's most recent known valuation. The pricing reflects strong enterprise adoption and $47 billion in annualized run-rate revenue, with capital earmarked for expanded compute capacity, fundamental research, and product rollout. OpenAI CEO Sam Altman publicly dismissed Anthropic's positioning as "fear-based marketing." This reshapes competitive dynamics at the top tier of the AI industry, making Anthropic one of the most valuable private companies in history.

🎮 NVIDIA opens γ-World for multi-agent simulation 🎮

NVIDIA Research has introduced γ-World (Gamma-World), a generative world model that opens access to multiple independently controllable agents with permutation-symmetric properties. The model delivers real-time rollouts and demonstrates zero-shot generalization, scaling from two-player to four-player settings without additional training. This advances scalable multi-agent simulation for robotics and game AI. The work underscores NVIDIA's continued investment in foundational AI capabilities beyond its core hardware business.
