Anthropic disabled all customer access to its Fable 5 and Mythos 5 AI models on June 12, 2026, following a US government order citing national security concerns. The government mandated suspension of access for all foreign nationals, including Anthropic employees, based on evidence of a potential jailbreak method for Fable 5.
The U.S. government ordered Anthropic to immediately shut down access to Claude Fable 5 and Claude Mythos 5 on Friday, citing national security concerns. Anthropic received the directive at 5:21 pm ET and has complied, disabling both models worldwide, but says the government received only verbal evidence of a 'potential narrow, non-universal jailbreak.'
The US government has ordered Anthropic to immediately suspend access to its Fable 5 and Mythos 5 models for all users, citing national security concerns over an alleged jailbreak technique. Anthropic states the directive, received at 5:21pm ET, provided no specific details beyond a claimed bypass method that other publicly-available models can already perform.
Anthropic disabled its Fable 5 and Mythos 5 AI models on Friday after receiving a U.S. government export control order at 5:21 p.m. ET. The directive, citing national security authorities, instructed the company to suspend all access by foreign nationals, including its own employees.
GitHub has updated Copilot CLI to reduce unnecessary handoffs between AI models. The improvement delivers faster command execution through better orchestration logic, implemented without adding new user configuration options.
GitHub has updated the orchestration logic in Copilot CLI to make it more selective about when to delegate tasks between language models. The changes reduce unnecessary handoffs and improve response times without introducing additional configuration settings.
Google has started rolling out information agents, the first type of Search agents announced at I/O 2026, exclusively for AI Ultra subscribers. The feature monitors blogs, news, social media, and real-time data sources 24/7 to deliver synthesized updates when conditions match user-specified queries.
Google's latest Android Bench results show Gemini 3.5 Flash ranking 6th with a 63.7% success rate, despite averaging $147.10 per benchmark run compared to Gemini 3.1 Pro Preview's $47.90. The newer model used 355.9 tokens per run versus 73.3 for its predecessor, while GPT 5.5 leads the benchmark at 74% success rate.
MiniMax has released M3, a multimodal model with approximately 428 billion parameters and 23 billion activated parameters. The model supports a 1 million token context window and uses MiniMax Sparse Attention to achieve 9× prefill and 15× decode speedups compared to its predecessor M2.
Moonshot AI has released Kimi K2.7 Code, a 1 trillion parameter Mixture-of-Experts model designed for long-horizon coding tasks. The model features a 256K context window and reduces thinking token usage by approximately 30% compared to its predecessor K2.6.
Apple announced five third-generation foundation models at WWDC26, headlined by AFM 3 Core Advanced—a 20-billion-parameter sparse model that runs on-device by activating only 1-4 billion parameters at a time. For the first time, Apple extended Private Cloud Compute to third-party infrastructure, with AFM 3 Cloud Pro running on Nvidia GPUs in Google Cloud.
Google announced that 3.5 million users have tested its Gemini for Home assistant since the early access program launched in October 2025. The company delivered over 2,500 bug fixes and 50 major feature updates based on user feedback, and is teasing a Google Home Speaker launch for next week.
Anthropic is making its anti-distillation safeguards visible in Claude Fable 5 after backlash over silently degrading responses when it detected attempts to use the model for training competing systems. Queries suspected of distillation will now be routed to Claude Opus 4.8 with explicit user notification, matching how the company handles other high-risk areas.
Cline released version 3.89.1 on June 11, addressing a critical bug where the Anthropic provider broke on VS Code 1.123 and later due to Node 24 runtime incompatibility. The update also adds support for DeepSeek V4's reasoning format.
Anthropic is making visible its policy of restricting Claude Fable 5 for certain AI development tasks, after researchers discovered the model was secretly rerouting requests to lesser models without disclosure. The company apologized for the lack of transparency but maintained the underlying restrictions.
Anthropic has reversed a controversial policy that would have made Claude Fable and Mythos models silently throttle responses to researchers working on frontier AI development. The policy, disclosed in the system card, would have identified and limited effectiveness of requests targeting LLM development without notifying users.
Google has released DiffusionGemma 26B, an open-weight text generation model under Apache 2 license. The model generates over 500 tokens/second according to testing on NVIDIA's free NIM API, where it produced 2,409 tokens in 4.4 seconds.
Apple's Xcode 27 adds native support for Google Gemini, joining existing integrations with Anthropic's Claude and OpenAI's Codex. The update also introduces improved interfaces, interactive planning, and multiturn Q&A capabilities for AI-assisted development.
Anthropic's newly released Claude Fable 5, the company's first public Mythos-class model, refuses to answer basic biology questions including 'what are mitochondria' and 'how mRNA vaccines work.' The company told The Verge the filters are intentionally 'overly conservative' to prevent bioweapon research, blocking 'most queries tied to biology work.'
Google DeepMind released DiffusionGemma, a 26B parameter mixture-of-experts model that generates text using discrete diffusion instead of autoregression. The model processes blocks of 256 tokens in parallel, achieving generation speeds exceeding 1100 tokens per second on H100 GPUs in low-batch settings.
