Anthropic says new safeguards sharply reduce AI distillation attacksAnthropic said reasoning-token extraction is now 10 to 100 times lower than before after it restricted access patterns, blocked proxy networks and banned tens of thousands of accounts. The company identified campaigns associated with Chinese AI firms including Z.ai, while acknowledging the claims were based on its own monitoring.→OpenAI links a 16,000-request reasoning-extraction campaign to Moonshot-associated usersOpenAI said activity peaked at 16,000 requests from more than 4,000 users on July 24 and 25, with a broader related cluster exceeding 15,000 users. The operators copied encrypted reasoning between conversations and asked another model to decrypt it; OpenAI said no encryption or stored user data was compromised.→Google unveils Gemini 4 Argon for trusted cyber defendersGemini 4 Argon supports a one-million-token output limit and is initially available through Google's Fairwind programme. Google reports leading results on DeepSWE and CWE-bench, while broader access remains gated pending safety testing.→Era by Eon exposes hidden-knowledge failures in enterprise agentsThe benchmark evaluates 12 agents on questions involving hidden facts distributed across generated company systems. The strongest agent answered 18 of 24 hidden-knowledge attempts correctly, while all agents together solved only two of 84 hardest attempts.→OpenAI releases GPT-6 Sol and Luna at lower pricesSol targets more complex tasks while Luna is positioned for cheaper, high-throughput work. OpenAI listed prices of $2 input and $10 output per million tokens for Sol, and $0.10 input and $0.50 output for Luna.→Google releases Gemini 3.8 Live with background reasoning for voice agentsGoogle announced Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking on 15 September. The models support visual context, switching across 97 languages and asynchronous tools; Google reports leading results on speech-agent benchmarks.→Motional open-sources nuReasoning dataset for autonomous-driving edge casesThe nuReasoning dataset was developed with UCLA’s Mobility Lab and focuses on common-sense reasoning for difficult driving situations. Motional said an earlier miniset had already surpassed 50,000 downloads and that the release is intended to support driving foundation-model research.→Vercel AI SDK adds GPT-6 reasoning configurationThe patch release for @ai-sdk/openai adds GPT-6 reasoning configuration updates. The change gives applications using Vercel's provider integration a supported path to pass the model-specific reasoning settings.→Google releases Gemini 3.8 Flash and restricted 3.8 Flash CyberGoogle says Gemini 3.8 Flash improves reasoning, coding and agentic tasks over 3.7 while keeping its introductory API price at $0.75 per million input tokens and $3.75 per million output tokens. Gemini 3.8 Flash Cyber is offered through Fairwind to trusted defenders, with Google reporting strong vulnerability discovery and automated patching performance.→Anthropic releases Claude Fable 5.1 and restricted Mythos 5.1Anthropic released Fable 5.1 and Mythos 5.1 as the same underlying model with different safeguards: Fable is generally available, while Mythos remains restricted to trusted cybersecurity and life-sciences programmes. Anthropic says cache-read pricing makes typical Fable workloads about 25% cheaper and highly agentic workloads up to 45% cheaper, while new safeguards cut cybersecurity false-positive blocks by 60%; customer-controlled Enterprise Frontier Safeguards are planned for later this year.→Apodex 1.1 pairs multi-agent reasoning with built-in verificationApodex announced version 1.1 as a system for professional, scientific and financial work that combines multi-agent collaboration with built-in verification. The release also includes Apodex 1.1 Mini as open weights and FrontierAgent as open-source software, although the company’s benchmark claims remain vendor-reported.→Apodex 1.1 pairs an open-weight model with verifiable executionApodex 1.1 combines multi-agent collaboration, tool execution, failure recovery and source-linked verification in a persistent workbench that can process code and other artefacts. The release also includes open weights for Apodex 1.1 Mini and the open-source FrontierAgent framework; its capability comparisons are company-published.→GLM-5.3-Flash launch exposed a cross-runtime reasoning-efficiency problemSGLang said GLM-5.3-Flash initially generated about twice as many reasoning tokens on open-source engines as on Z.ai's API on AIME and GPQA, despite similar scores. Fireworks, vLLM, SGLang and Z.ai then reran tests and updated the serving path; SGLang said the excess was concentrated in some reasoning prompts and was not seen on the cited agentic benchmarks.→IBM releases Granite 4.2 open reasoning models for enterprise agentsGranite 4.2 is available in 3B, 8B and 30B sizes, with IBM describing native thinking and agentic reinforcement learning for multi-step enterprise tasks. The release also includes lightweight Granite Speech 5.0 Turbo CTC models intended for fast transcription on edge devices.→Claude Code users report blank reasoning blocks despite billingThe Register reports that Opus 4.8 and Sonnet 5 requests can return missing or incomplete thinking summaries. Anthropic documentation states that thinking tokens remain billable even when the thinking content is collapsed or redacted, and the company was investigating the behaviour.→
