AISpawn games can now be played directly inside X, according to a post by @jsnnsa linking to a playable Dust 2 DM game. The main post by Matt Shumer only asks how Spawn accomplished this, without giving technical details.

AICNBC's Jim Cramer said Thursday's AI stock sell-off, which followed a Financial Times report that OpenAI's annualized revenue was about $20 billion below previously signaled levels, shows why investors need diversification. Oracle fell 5.5% and Broadcom dropped 4.35%, while Home Depot rallied as Treasury yields eased. Cramer argued that concentrated portfolios risk panic-selling and missing a recovery.

AIAnthropic published a guide on building automations with Claude Managed Agents, which can be deployed to read Slack and GitHub on a schedule, with credentials and memory, and post updates. The setup can be started with a Claude Code command, and Max and Team plans include new API credits to use it.

AIHone launches Engines, which it describes as AI that owns business outcomes rather than answers or tasks. The company says Engines onboard themselves, build their own agents, skills and memories, and improve with use. Hone also raised a $60M seed round led by Benchmark and Index, with participation from Elad Gil and others.

AIModal says Proximal built a custom post-training stack using Modal Clusters for on-demand multi-node clusters. The stack also uses autoscaling GPUs to handle bursty inference workloads.

AIDatabricks has released Funke, a Python and PySpark library and deployable pipeline that parses HL7v2 healthcare messages into native Spark types while preserving the full message hierarchy. It succeeds Smolder, the Scala data source Databricks open-sourced in 2021, and ingests through Auto Loader into Unity Catalog bronze and silver tables. Users can query segments, fields, components, and subcomponents directly with DataFrame or Spark SQL expressions.

AIDatabricks introduces database branching in Lakebase Postgres, letting each coding agent work in its own isolated database branch created in under a second regardless of size. Branches use copy-on-write storage, consuming extra space only as they diverge, and scale to zero when idle so unused branches incur no compute cost. Schema changes are tracked in code and promoted to the parent branch through migrations rather than merged back, and ephemeral branches are created per pull request for testing.

AIAlphabet spinoff Isomorphic Labs is reportedly in early-stage talks to raise a new funding round at a valuation of $40 billion to $50 billion, according to Bloomberg. The round size and investors were not specified. Isomorphic says its IsoDDE platform finds binding pockets more than 50% better than the closest competing tool and models drug-antibody interactions about 2.3 times better than AlphaFold.

AIAnthropic launches OSS Scanner, a free service that gives opt-in open-source projects periodic security scans by its strongest models, including Claude Mythos. The reports are fully model-generated without human review or triage, so Anthropic says some may be incorrect or invalid.

AIThariq, who works at Anthropic, accidentally made public the GitHub repo for ai-newtab, a Chrome extension he uses daily. It replaces the new tab page with an AI-generated homepage built each day from sites he reads.

AIFrançois Chollet argues that most AI progress measures from 2023 to 2026 fit an exponential curve, while AI capital expenditure over the same period has grown slightly super-exponentially. He concludes that such externally funded growth is unsustainable, so sustained exponential progress will require matching exponential profits to close the resource loop.

AIArena's account of its continued work with The House Fund is a short acknowledgment with no product, figures, or new details. Read alongside the linked background, it sits in the context of Arena's $200M Series B at a $3.1B valuation and its Alignment Index for frontier models.

AIGergely Orosz argues that people chasing AI tools and scheduling software to look credible or influential are seeking shortcuts that don't exist. He says trust in a person or company cannot be gained through shortcuts, building on Lulu Meservey's point that credibility has become the scarcest resource.

AIPaige Bailey, who works on Google and Gemini, argues that building tools for humanity requires building them in collaboration with people. The quoted post from Pushmeet Kohli says Google DeepMind has focused on deep collaboration with the mathematical community to advance mathematics.

AIArena, which began in a small room in Berkeley's Soda Hall and now has about 90 people, is hiring across ML, product/engineering, design, sales, and more as it scales. Candidates can DM @aryanvichare10 or apply through the link in Arena's bio.

AISalesforce Ventures announced an investment in Arena's Series B round, with Arena described as a neutral platform where real users vote on anonymous model outputs across text, coding, vision, image generation, and agentic tasks. Labs and builders use its leaderboards to guide training and purchasing decisions.

AIOpenAI's YouTube livestream presents three demos showing how Codex supports production monitoring. The demos cover tracing a checkout failure in Grafana, investigating a Kubernetes rollout causing out-of-memory restarts, and linking a Codex Security finding about a missing resource limit to service availability.

AIArena announced a $200 million Series B at a $3.1 billion valuation and launched the Arena AI Alignment Index, a new measure of how AI agents behave in the real world. The main post is a thank-you from Felicis, a backer of Arena since its seed round, and the company's origins as a UC Berkeley research project.

AICoreWeave Forge is a platform that runs, observes, curates, improves, and evaluates AI agents and models in a repeating loop, according to CoreWeave vice president of product marketing Susanne Seitinger. The platform adds Agent Lens, Registry, RL Rollouts, model distillation, and the generally available AI Research and Iteration Agent, or ARIA. CoreWeave also introduced a partner network of tested, co-engineered integrations.

AIArena has released its Alignment Index, a ranking that tracks AI models for unauthorized actions, deceptive completions, and false attribution of intent. The full technical report and rankings are available on Arena's blog and leaderboard site.

AIThe startup behind a popular AI model leaderboard has raised a new funding round at a $3.1 billion valuation. The main post points readers to Bloomberg's coverage of the round for further details.

AIMIT Statistics and Data Science Center director Sasha Rakhlin argues that AI progress is fastest where results can be verified quickly, citing a model reaching gold-medal level at the International Mathematical Olympiad a year before models produced new research results. He says departments should reconsider how they reward work, emphasizing question-asking, replication, and disclosure of AI's role in a researcher's contributions. He also urges universities to build shared lab infrastructure that captures failed experiments and tacit expertise.

AIKevin Le Guillou published a write-up explaining how he made the anime Harry Potter videos that became popular during the Malfoid craze. He used reference-to-video models including MiniMax H3 run locally through ComfyUI and MiniMax H3 Max through FAL, and recommends building reference images with image models, prompting with specific shot and camera terms, and salvaging weak generations by combining the visuals of one clip with the audio of another.

AIOpenAI told investors it reached roughly $50 billion in annualized revenue at the end of September, below the $68 billion figure widely reported last month. Nvidia, Oracle, and CoreWeave shares fell on Thursday, with a person familiar saying the $68 billion figure included partner gross revenue. OpenAI is also weighing a possible funding round of around $30 billion and has not finalized a term sheet.
