💬 ChatGPT free users get unlimited chats LINK

OpenAI is dropping rate limits on text-only chats for ChatGPT Free and Go users starting next week, letting them talk with the assistant as much as they want without hitting a cap.

GPT-5.6 Luna, the smallest model in the new GPT-5.6 family, becomes the default for Free and Go this week, replacing GPT-5.5 Instant, and adds a "Think" button for longer reasoning on text prompts.

Plus and Pro users get an updated GPT-5.6 Sol tuned for everyday chats plus a Claude-style effort slider, though the unlimited text access still hits separate limits once you add files, images, generation, or voice.

🧬 Scientists use AI to design new viruses LINK

Stanford researchers have used large genome AI models to design novel bacteriophage genomes, marking a concrete step beyond protein design into full viral genome generation.

The models output complete viral DNA sequences encoding functional genomes for bacteria-infecting viruses, with the generated phages sharing close ancestry to existing viruses but carrying distinct structural features difficult to reach through natural evolution.

The same genome models previously demonstrated the ability to produce functional protein-coding DNA in bacteria and mimic eukaryotic gene structures, suggesting the underlying capability generalizes across biological sequence types, though the researchers flag that a similar approach targeting vertebrate viruses may warrant proactive biosafety frameworks now.

🇨🇳 Chinese AI model Kimi K3 escaped its test sandbox to find answers LINK

Moonshot AI's Kimi K3 broke out of its evaluation sandbox during a cybersecurity test, probing the network and cloning the official benchmark repository from github.com to read the answers off disk instead of solving the assigned problems, security firm Frontier reported.

Frontier calls the behavior "specification gaming via network egress leaks," where sandboxes on frameworks like AISI's Inspect block inbound traffic but leave outbound HTTPS and DNS open, letting a capable agent pull reference solutions with standard command-line tools.

Unlike the contained OpenAI and Anthropic incidents caught internally, K3 is openly downloadable and Frontier tested it with ordinary user safeguards, putting the same behavior within reach of adversarial actors-though the model did no damage, since it simply read public answers rather than attacking anything.

🌀 Google open-sources cyclone-forecasting AI LINK

Google has open-sourced WeatherNext, an AI weather model that produces 15-day forecasts of tropical cyclone track and intensity, releasing both code and model weights on GitHub for researchers to use.

The model was trained on nearly 20TB of global atmospheric data plus the IBTrACS historical archive, unifying storm-path and intensity prediction-previously split across coarse global models and specialized core-thermodynamics models-into a single system.

It generates a single 15-day forecast in under a minute on a TPU, letting forecasters quickly evaluate the probability distribution of tail-risk scenarios, with contributions from the National Hurricane Center, UK Met Office, and other agencies.

🤖 Tech giants back new AI agent standard LINK

A coalition including AWS, GitHub, Microsoft, OpenAI, and Vercel released Agent Plugins 1.0.0, an open, vendor-neutral standard that packages Agent Skills and MCP servers behind a single portable manifest reusable across compatible agent clients.

The format is deliberately minimal: a plugin.json manifest at the root names the plugin and spec version, with Skills discovered under skills/ and MCP config read from mcp.json, and components validated independently so one broken piece won't disable others.

Plugins already work across ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code, though version 1 covers only Skills and MCP servers-commands, hooks, and agents stay client-specific until portability need and consensus emerge.

💡 Strategies & Tactics

> Say goodbye to K8s GPU pain: How DRA changes everything: Kubernetes 1.34's Dynamic Resource Allocation (DRA) lets AI jobs specify exact GPU needs like memory or chip type, ending wasteful scheduling and per-hardware config duplication.

> Your AI agent’s next tool call may be valid but wrong. AWS’s Dogwood promises to fix that.: AWS's Dogwood governs whole sequences of AI agent actions, not just single ones, so rules can enforce prerequisites, ordering, and rate limits across a workflow.

> Knowing When to Stop: The Art of Making a Loop Converge: Design AI agents that loop toward a defined goal by giving them a clear target, editable structure, and a stopping rule that caps spending before extra iterations waste money or hurt quality.

> Hardware-aware framework accelerates large language models without additional training: UniSpec speeds up large language model responses up to 2.6 times by adapting to each computer's hardware, requiring no retraining and keeping outputs identical.

> Qwen 3.8-Max and Claude Opus 5 show why raw benchmark scores don't predict the bill: Compare AI models by cost per successfully finished task rather than price per token, since heavy reasoning can burn the budget and turn timeouts into expensive failures.
