MaxProof achieves gold-medal-level performance on IMO 2025 and USAMO 2026 via population-level test-time scaling
MiniMax introduces MaxProof, a test-time scaling framework for competition-level mathematical proof built on their MiniMax-M3 model. The system trains three capabilities — proof generation, verification, and critique-conditioned repair — then at inference time runs tournament selection over a population of candidate proofs. MaxProof scores 35/42 on IMO 2025 and 36/42 on USAMO 2026, exceeding the human gold-medal threshold on both competitions.
Aligning to What? Rethinking Agent Generalization in MiniMax M2
MiniMax published a blog post discussing alignment and generalization challenges in their M2 agent model. The piece appears to examine how RLHF or similar alignment techniques interact with agent generalization across tasks. Published on Hugging Face's blog, it reflects MiniMax's thinking on training methodology for their M2 model.
Anthropic Identifies Industrial-Scale Distillation Attacks by DeepSeek, Moonshot, and MiniMax
Anthropic has publicly identified three Chinese AI laboratories—DeepSeek, Moonshot AI, and MiniMax—as conducting coordinated, large-scale distillation attacks against Claude, generating over 16 million exchanges through approximately 24,000 fraudulent accounts in violation of terms of service. The campaigns targeted Claude's most differentiated capabilities including agentic reasoning, tool use, coding, and chain-of-thought generation, with MiniMax alone responsible for over 13 million exchanges. Anthropic frames these attacks as a national security concern, arguing that illicitly distilled models strip out safety safeguards and undermine US export controls. The company claims high-confidence attribution via IP correlation, request metadata, and infrastructure indicators, in some cases corroborated by industry partners.
MiniMax M2.7 proprietary reasoning model competes with Gemini and Claude Opus; roundup covers Cursor Composer 2, MAI-Image-2, Claude Code Channels, and Anthropic defense dispute
MiniMax released M2.7, a proprietary reasoning model that achieved 66.6% on MLE Bench Lite (tying Gemini 3.1) and 56.22% on SWE-Pro, priced at $0.30/$1.20 per million tokens, with the shift to proprietary marking a potential strategic pivot among Chinese AI labs away from open weights. Cursor released Composer 2, an agentic coding model built on a fine-tuned Kimi 2.5 (via Moonshot partnership), priced 86% cheaper than its predecessor and scoring 73.7 on SWE-bench Multilingual. Anthropic released Claude Code Channels, routing Telegram and Discord messages into local Claude Code sessions via MCP plugins, and separately filed a court response denying it has any backdoor or kill switch into military deployments of Claude. Microsoft announced MAI-Image-2, a text-to-image model ranking third on Arena.ai among research labs.
Claude Opus 4.8 Launches with Improved Honesty; Anthropic Previews Mythos-Class Models and Dynamic Workflows
Anthropic released Claude Opus 4.8 with improvements in coding, reasoning, agentic tasks, and notably better uncertainty flagging—approximately four times less likely than Opus 4.7 to let code flaws pass uncommented. Alongside the model, Anthropic introduced dynamic workflows in Claude Code enabling tens to hundreds of parallel subagents for large-scale engineering tasks, an effort-control slider, and a 3x price cut on fast mode. Anthropic also previewed Mythos-class models, positioned above Opus in capability, currently available to a limited set of organizations for cybersecurity work pending broader safety clearance. The same digest covers MiniMax M3 (open-weights, ~60% SWE-Bench Pro), Nvidia's RTX Spark superchip, Cosmos 3 world model, and a GR00T/Unitree robotics partnership.
Latest open artifacts (#19): Qwen 3.5, GLM 5, MiniMax 2.5 — Chinese labs' latest push of the frontier
A Interconnects newsletter roundup covering recent open-weight model releases from Chinese AI labs, specifically Qwen 3.5, GLM 5, and MiniMax 2.5. The piece frames these as a continued frontier push from Chinese research organizations. The body content is minimal beyond the title and greeting, suggesting this is either a stub or the full content was not captured.
Gray market API proxy network enables discounted access to U.S. AI models in China via fraud and distillation
A ChinaTalk report details an informal ecosystem of API proxy servers, account farms, identity brokers, and token resellers that gives Chinese developers access to U.S. AI models like Claude, ChatGPT, and Gemini at steep discounts — sometimes 10% of market price — through methods ranging from terms-of-service violations to credit card fraud. CISPA Helmholtz Center research found proxy 'Gemini-2.5' access achieved only 37% on MedQA versus 83.82% via Google's official API, suggesting model substitution is common. The network also harvests API call logs as training data, feeding the industrial-scale distillation practices Anthropic accused DeepSeek, Moonshot, and MiniMax of in February. The White House acknowledged the distillation threat in an April memo, framing it as an adversarial national security concern.
