What's New in AI

Great American AI Act - first bipartisan draft of a US federal AI framework

Representatives Obernolte and Trahan release a 269-page bipartisan discussion draft of the Great American AI Act - the most credible federal AI legislation proposed to date. It would impose binding obligations on $500M+ revenue frontier AI developers and preempt state AI laws for three years. If enacted, it would replace the current state-by-state patchwork with a single federal compliance regime.

Government-gated frontier AI - a new release paradigm

Claude Fable 5 (Anthropic) and GPT-5.6 Sol/Terra/Luna (OpenAI) both launched under US government review restrictions in June 2026, within weeks of each other. OpenAI previewed GPT-5.6 with the government before launch and said it is developing a 'repeatable process' for future releases. The most capable AI models are now subject to national security vetting before broad public access - a structural shift in how frontier AI reaches developers and enterprises.

Claude Fable 5 - new capability ceiling, briefly pulled by US export order

Anthropic releases Claude Fable 5 - state-of-the-art across coding, science, vision, and knowledge work at $10/$50 per 1M tokens. Within three days, a US government export directive temporarily forced it offline; it was reinstated June 22. The first government-directed suspension of a major AI model established a new precedent for how frontier models reach the public.

Apple WWDC - Gemini-powered Siri, Claude and Gemini as iPhone extensions

Apple announces Siri AI powered by a custom Google Gemini model (1.2T params), with multi-AI Extensions in iOS 27 - users route queries to Claude or Gemini directly from Siri settings. Consumer AI becomes platform-level infrastructure: Anthropic and Google gain access to the iPhone installed base without building their own native iOS integration.

Microsoft Build - MAI models, first in-house frontier AI

Microsoft announces 7 MAI models at Build 2026. MAI-Thinking-1 (35B active params, 256K context) is Microsoft's first in-house reasoning model - trained without OpenAI distillation, preferred over Claude Sonnet 4.6 in blind evals. MAI-Code-1-Flash becomes the backbone of GitHub Copilot for all plans, giving Microsoft direct control over its most-used developer AI tool.

Graphify - codebase knowledge graphs go open-source

An MIT-licensed tool that turns any codebase into a queryable knowledge graph using local Tree-sitter parsing (no source code sent to external servers). 71.5× token reduction on real codebases. Crossed 22,000 GitHub stars in under ten days.

Claude Code Routines - scheduled AI automation

Anthropic added three trigger types to Claude Code: scheduled (cron-like), API-triggered, and GitHub event-triggered. AI-assisted automation moved from manual prompting to persistent background workflows.

Grok 4.3 - xAI flagship with 1M context window

xAI releases Grok 4.3 at $1.25/$2.50/1M tokens with a 1M token context window - one of the largest of any commercial model. $150/month free developer credits available. Live X/Twitter search integration remains Grok's unique differentiator.

Llama 4 Scout & Maverick - open-weight multimodal MoE

Meta releases Llama 4 Scout (109B MoE, 10M context) and Maverick (400B MoE, 17B active). Apache 2.0 licensed, natively multimodal, matching GPT-4o on major benchmarks at a fraction of inference cost. Scout fits a single H100. The open vs closed gap narrowed significantly.

Gemini 3.1 Pro leads scientific reasoning

94.3% on GPQA Diamond - a PhD-level science benchmark. 77.1% on ARC-AGI-2. Google's Gemini family regained benchmark leadership in the first quarter, intensifying the rotation between labs at the top of the leaderboards.

GPT-5 integrated into ChatGPT

OpenAI's most capable model yet, with major improvements in multi-step reasoning, scientific problem-solving, and multi-modal understanding. Shipped directly into ChatGPT, making frontier capability accessible to all subscribers.

LazyGraphRAG - knowledge graphs become affordable

Microsoft's LazyGraphRAG reduced knowledge graph indexing cost from $20–500 to under $5 by deferring community summaries to query time. Graph RAG moved from a research technique to a practical production tool.

GPT-4.1 family - OpenAI's mid-range tier

GPT-4.1, Mini, and Nano gave developers a coherent OpenAI lineup matching the tiered structure Anthropic popularised. The cost gap between tiers widened: GPT-4.1 Nano at sub-$0.10/1M tokens vs GPT-4.1 at $2.00/1M.

Meta Llama 4 - natively multimodal MoE

Llama 4 Scout and Maverick used Mixture-of-Experts architecture (activating only a fraction of parameters per token) to deliver competitive performance at dramatically lower inference cost. Maverick beat GPT-4o on multiple benchmarks. Behemoth (2T total params) signalled the raw scale Meta was willing to deploy.

Gemini 2.5 Pro leads benchmarks

Google's Gemini 2.5 Pro with 'thinking budget' took top positions on coding and reasoning leaderboards. The 'thinking budget' feature let developers trade cost against reasoning depth - a new knob for production optimization.

Claude 3.7 Sonnet - hybrid reasoning

Anthropic's first model with an explicit 'extended thinking' mode - letting users toggle the reasoning depth. Topped SWE-bench for autonomous software engineering tasks. The practitioner shift toward reasoning models accelerated.

DeepSeek R1 - the 'DeepSeek shock'

A Chinese lab released an open-weight reasoning model trained for approximately $6M - matching OpenAI o1 on coding and maths. It became the #1 free app on the US iOS App Store within days. The narrative that frontier AI required billions in training compute collapsed overnight.

OpenAI o3, Gemini 2.0, DeepSeek V3

A landmark month: o3 achieved near-human scores on ARC-AGI; Gemini 2.0 Flash matched o1 performance at lower cost; DeepSeek V3 quietly shipped as a top-tier open-weight model. The frontier moved dramatically in 30 days.

Anthropic open-sources MCP
