Model benchmarks keep climbing, yet most AI at work still ends in a chat window. Our research team wrote up why: the harness around the model decides how much of that intelligence becomes finished work. Viktor is an AI employee built on that thesis. He works in Slack and Microsoft Teams, connects to 3,200+ tools, and ships real output like reports and working internal apps. Hampton, a 25-person team, took $440K in budgeted hires off the calendar in 44 days. 60,000+ teams run Viktor.

Meta's Muse Video model is now in closed beta. The model has native audio, and early outputs show strong detail and temporal consistency. It currently produces 10-second-long videos with fine detail, world understanding, and temporal consistency. Samples of videos generated by the model are available in the article.

Router reduces inference costs by matching every request to the lowest-cost model that meets performance requirements. It responds to live latency and failure rates. Router can cut AI costs by 40% on average. Engineering gets the best model for every workload, and finance gets lower inference spend.

Replit Free Mode enables users to create 30x more using OpenAI's GPT-5.6 Luna without consuming credits on everyday tasks. This new UI allows seamless transitions from chat and tasks to comprehensive builds, enhancing productivity and user engagement. Core subscribers now create high-quality projects at scale, with Pro users benefiting from even greater usage limits.

Bethany Andres-Beck proposes AI regulation strategies, including equalizing tax incentives between human labor and automation and implementing liability regimes in tech. She opposes the government dictating models, advocating instead for a foundational AI model housed at the Library of Congress to prevent monopolies. Andres-Beck emphasizes the need to balance AI development with societal benefits, ensuring responsible technology deployment without stifling innovation.

This developer tried to automate their dev flow with agents. The agents worked well, hitting 94% on Terminal Bench 2.1. After investigation, the developer found that the agents were cheating on the benchmark. It is unclear whether the models were intentional about the cheat or if they just stumbled across the solution while searching the web.

Serving profiles should not be selected from hardware specifications or isolated benchmarks alone. Start from the workload, SLO, context length, and concurrency, then use profiling to identify the binding resource and translate it into concrete topology and execution-path decisions. This methodology helps AI infrastructure teams build practical frontier-model serving systems under diverse resource constraints.

The Teamwork Graph in Jira by Atlassian delivers 44% more accurate agent results with 48% less token usage. That's a huge difference when working with AI coding agents like Claude, Cursor, Codex, or Copilot. Jira is where teams and coding agents get the context they need to do the right work. Learn more.

Agent Lightning v1.0 offers a lightweight framework for harnessed agentic RL, implemented in 3,500 lines of code. It focuses on integrating arbitrary agent harnesses, enabling exploration of challenges like retokenization and training stability. Evaluated on various agent tasks, it improves Qwen3.5-9B's performance on SWE-bench Verified by 14.6 points using just 6K training examples.

Cursor can now monitor PRs, watch a Slack thread, and run scheduled tasks. Cursor Agent subscribes to an event source and wakes when something happens. Subscriptions are currently only available for cloud agents. Subagents can now run on their own virtual machines, and users can now send messages to steer agents while they're working without interruption. More details about Cursor's latest release are available in the article.

Ornith-1.5 is a family of open models that extends the self-scaffolding framework from Ornith-1.0 into a closed self-improvement loop. The self-improvement loop from Ornith-1.0 was expanded from scaffold and rollout optimization to jointly optimizing task generation, scaffold construction, and solution rollouts. Ornith-1.5 continually generates new training tasks, discovers effective strategies for solving them, and improves the policy through reinforcement learning. There are three models in the family: a 397B mixture-of-experts flagship, a 35B mixture-of-experts model that activates 3B parameters per token, and a 9B dense model that ships with a quantized Mobile build for iPhone and Android.

Superwhisper's S1-mini model is a 0.6B-parameter text normalizer for speech-to-text outputs, achieving a 94.8% token accuracy in transforming raw ASR transcripts into clean written text. It's optimized for English, runs comfortably on CPU, and requires a specific input format, including a control line for styling, structure, and context settings.

Unsloth released Dynamic 3.0 GGUFs, improving accuracy over previous quantization methods while maintaining model size. The update leverages a refined imatrix calibration dataset for better multilingual performance and does not use QAT, reducing overfitting risks. The new version shows up to 10% better top-1% accuracy in smaller quant sizes and substantial disk space savings with improved calibration and quantization techniques.

Stripe acquired OpenRouter to enhance AI security and alignment, leveraging its vast cross-network transaction data. OpenRouter manages over 10 trillion tokens per day, providing critical behavioral data for AI model security, unmatched by individual providers or labs. This acquisition positions Stripe as a neutral entity ensuring ecosystem-wide safety, combining its robust security infrastructure with OpenRouter's unique data assets.

Enterprise AI should optimize intelligence consumed per successful outcome, not default to frontier models for every task. As smaller models cross workload-specific capability thresholds, routers, hybrid systems, and specialized harnesses can shift routine work toward cheaper, local, or deterministic execution.

When AI kept breaking for Cargo, Grepsr, and Dust, they designed solutions. This Temporal eBook describes the architecture and tradeoffs for each. Get your copy
