Meta Launches Muse Wonder and Muse Wonder Full: MSL's Next-Gen Frontier Models

Meta Superintelligence Labs (MSL) released Muse Wonder and Muse Wonder Full, its second-generation model family, about 14 months after the lab was founded. Muse Wonder is available via the Meta Model API and Muse Code, while Muse Wonder Full is exclusive to Muse Code subscribers. Third-party evaluations place the models near the frontier, with Wonder Full beating Fable and Astra on some benchmarks.

OpenAI publishes 722 math papers, solving 90 of top 500 open problems

OpenAI released 722 mathematical manuscripts from an internal frontier model, grouped into 372 families of related results, and claims to have solved 90 of the top 500 open math problems. Result 003, called the Quasi-Riemann Hypothesis, is described as somewhere between a Fields Medal result and "the biggest result in number theory in 200 years." The release includes papers, proof artifacts, and selected reasoning summaries, and consulted the Institute for Advanced Study's independent Advisory Group on Mathematics and AI.

Reflection Launches Beam: 501B-Parameter Open MoE Model

Reflection announced Beam, a text-only 501B-total / 23B-active MoE model for coding, agentic and scientific work, trained from scratch with full Apache 2.0 weights due this month. The team cites 23.8T pretraining tokens, a stable RL/OPD run on 10K GB300s with over 100M rollouts, and claimed 80.9 on SWE-bench Verified. It marks Reflection's arrival as a functional neolab in the US open-model ecosystem, though competitors like GLM 5.3, Kimi K3, Qwen 3.8 Max, and DeepSeek V4.1 Flash are generally ahead.

Eric Nguyen: Bio-security is an AI Arms Race

Eric Nguyen, co-founder of Radical Numerics, explains why the same models that increase biological capability can also keep defense from falling behind. He shares his experience developing Genomic Language Models like Evo and Evo 2 at Stanford and Arc Institute, which were used to generate functional bacteriophage genomes. The article also references Clem Delangue's argument for open cyber-warfare defenses and Anthropic's filters flagging cyber-security and biology.

Anthropic launches Claude Opus 5.5 as OpenAI releases GPT-6 Sol and Luna, intensifying API price war

Anthropic shipped Claude Opus 5.5, the first model in its new Claude 5.5 family, claiming Fable 5.1-level capability at 40% lower cost than Opus 5, with improvements in agentic coding, computer use, knowledge work, and writing. About an hour later, OpenAI released GPT-6 Sol and Luna priced 50% lower than GPT-5.6, as both labs credited efficiency work for API price cuts, escalating competition.

Can Skills Learned in Games Transfer to Real-World Work?

Good Start Labs, co-founded by CEO Alex Duffy, is turning games like Diplomacy into training material for AI models to teach strategic thinking and other transferable skills. The startup, spun out of Every with $3.6 million in funding, was inspired by a 2025 Twitch stream where OpenAI's o3 model won by planning a betrayal while Claude's Opus 4 refused to lie and lost. Duffy claims fine-tuning on Diplomacy improved model performance on customer support and industrial operations benchmarks.

Top AI Open Source Projects Shut Off External PRs, Prefer Own Agents

Leading AI-native open source projects like Flue and tldraw are rejecting external pull requests, partly because they are often AI-generated. Instead, maintainers use their own agents to manage contributions. Vercel's AI SDK project deployed a 'software factory' with specialized agents to handle its PR and issue backlog, improving efficiency and reducing review time.
