Meituan LongCat Team Releases 1.6-Trillion-Parameter Natively Multimodal Model LongCat-2.5

The Meituan LongCat team has released LongCat-2.5, a natively multimodal model designed for long-horizon agent tasks, with a total parameter count of 1.6 trillion and approximately 48 billion parameters activated per Token. On benchmarks published by Meituan such as AutomationBench and LongCatClawBench, LongCat-2.5 leads Claude-Opus-5 and GPT-5.6-Sol; on Terminal Bench v4.0 it scores 38.5, surpassing GPT-5.6-Sol but trailing Claude-Opus-5. The model converts visual signals into multi-level discrete Tokens and processes them uniformly with text, and it redesigns its parallelism strategy for domestic accelerators whose single-card memory is under 80GB, raising single-card throughput for long-sequence SFT by 86% over the DDP baseline.

Why read thisThe original article presents the model's comparative results on multiple Agent benchmarks and details of training optimization on domestic accelerators, which can be used to assess the engineering approach for long-horizon agent models.

Qwenputer embeds a RISC-V CPU in the Qwen3.5-4B weights and uses GDN state as memory

On Qwen3.5-4B, Qwenputer uses a compiler to write a 32-bit RISC-V CPU into about 11 layers of additional weights, and treats the model's built-in Gated DeltaNet state as addressable RAM, running C and MicroPython in the forward pass without calling an external runtime. In testing, the DeepMind arithmetic set reached about 97.5–100%, NUPA long integers improved from 48.6% for the base model to 100%, and about 230,000 CPU output positions showed zero mismatches against the reference machine. The costs are a checkpoint of about 18.8 GB, several decode tokens required per CPU instruction, and the need to drive it through RvChat rather than bare generate().

Why read thisThe original text provides arithmetic benchmark comparisons along with costs such as checkpoint size and decoding overhead, which can be used to judge the feasible boundaries of the in-weight computation approach.

Tomasz Tunguz: Who Will Cross the Trillion-Dollar Revenue Chasm First

Tomasz Tunguz analyzes the $1 trillion revenue targets separately proposed by Andy Jassy and Elon Musk. Extrapolating at current growth rates with 15% annual decay, Google Cloud and SpaceX will reach $250 billion in quarterly revenue ($1 trillion annualized) in 2030, with AWS following in 2032. He notes that the market has sold off some cloud providers out of concern that cash flow from legacy businesses cannot sustain capital expenditures; Google's search advertising growth has already slowed from 19% in Q1 to 12% in Q3, and AI Mode's monetization rate is lower than that of traditional search. Microsoft is the only hyperscaler to boost ARPU through AI faster than seat growth slows, while ServiceNow's market value has fallen 29% on concerns that its seat-based business will be eroded by AI.

AMD Acquires World Labs for $8.2 Billion; Fei-Fei Li to Serve as AMD Executive Vice President and Chief Scientist

AMD announced an all-stock acquisition of World Labs, founded by Fei-Fei Li, for approximately $8.2 billion. After the deal closes, Fei-Fei Li will serve as AMD Executive Vice President and Chief Scientist, reporting directly to Lisa Su, and World Labs' roughly 70-person team will be integrated as a relatively independent research unit. The article reviews Fei-Fei Li's three directional choices—from ImageNet, to AI democratization, to spatial intelligence—and notes that this acquisition is about 52% higher than World Labs' $5.4 billion valuation after its February 2026 Series C funding round. The author believes that what comes next is whether the performance gains of Atlas and Marble on MI450 can continue the curve of the 4x speedup on MI325X, and whether other spatial intelligence teams will consequently shift to AMD hardware.

Google Research proposes the sleep framework, enabling LLMs to retain knowledge during continual learning

Google Research proposes the sleep framework, which introduces periodic sleep stages to LLMs to consolidate short-term context into long-term parameters, thereby mitigating catastrophic forgetting and static knowledge cutoff. The framework consists of two stages: memory consolidation and dreaming. The former uses MoE parameter expansion and knowledge seeding based on GKD and reinforcement learning imitation, while the latter achieves self-improvement through random expert activation, filtering synthetic samples, and RL refinement. On BABILong, this method scales nearly perfectly within 10M tokens, and achieves accuracies of 79.2%, 69.0%, and 46.1% on AIME 24/25 and HMMT 25, respectively.

OpenAI Says Its Model Produced Results in Three Research Areas: Mathematics, Computer Science, and Physics

On October 26, 2026, OpenAI announced that its internal model had produced three research results in the fields of mathematics, computer science, and physics, including a counterexample to the long-standing Exponential Time Hypothesis (ETH) in computational complexity theory. In mathematics, the model provided a proof of the local smoothing conjecture in arbitrary dimensions, and thereby resolved the Kakeya conjecture and the Stein restriction conjecture; the output was obtained on October 18 and Lean formalization was completed the next day. The computer science result was verified by a group led by Russell Impagliazzo, Ramamohan Paturi, and Ryan Williams, and OpenAI agreed to disclose all raw data and fund related conferences; the physics result provided a rigorous existence proof for a four-dimensional quantum field theory with gauge fields and interacting fermions, and also included a pure Yang–Mills existence proof, with the group led by David Gross deciding to temporarily not disclose the AI-produced materials and to write up the results themselves.

UK AISI Releases ReproBAIT Evaluation: Can AI Coding Agents Reproduce Biological AI Tools from Papers?

The UK AI Security Institute's Chem-Bio team, in collaboration with SecureBio, built the ReproBAIT evaluation to test the ability of AI coding agents to reproduce biological AI tools (BAITs) given data and limited public information. Results showed that simpler tools could be reproduced within 4 hours and under a $20 compute budget; ProteinMPNN reached 96.5% reproduction fidelity with Claude Opus 5 when the full paper was provided, while the most complex tool, RFdiffusion3, was not successfully reproduced by any agent within the time limit. Based on this, the team noted that merely withholding code or restricting paper information does not equal safe release, and that controlling access to underlying biological data may be more effective than controlling code.
