The essential reading of generative AI and agents, open in a clean reading view, with Meow and Standard summaries when available. No account needed to read.
AlphaGo Zero started from self-play instead of human game records, quickly surpassed human-level play, and beat the previously published champion-defeating AlphaGo 100 games to 0.

MuZero learned to plan in Go, chess, shogi, and Atari without being given their rules, by modeling only what helps its decisions.

AlphaDev searches CPU instructions for faster algorithms instead of merely refining familiar code—a promising approach when small routines are called again and again.
AlphaEvolve shifts LLM-assisted discovery from generating code to repeatedly testing and evolving programs; Google reports production computing uses and new mathematical results.
An LLM agent’s autonomy comes from the system around the model: planning, memory, and tools. Those parts extend what it can do, but do not remove its core failure modes.
The author calls the gap between AI’s benchmark achievements and its limited change to the world the “utility problem”—and argues that evaluation must address it.
An agent is not a yes-or-no label: the article ties autonomy to how much application control the LLM owns—and to the engineering support that level demands.
The report argues that coding agents should be evaluated in full repositories, where they must locate files and use test feedback—not only solve isolated coding problems.
Opus 5.5’s sharpest pitch is cost per completed task: Anthropic reports competitive coding results against GPT-6 Astra and GPT-5.6 Sol at a fraction of the task cost.
Anthropic launches one underlying model with two safeguard profiles: Fable 5.1 is broadly available, while Mythos 5.1 is restricted. The company pairs performance and research claims with lower cache-read prices and tighter access controls.
Claude Opus 4.7 was about 20 times faster than the fastest human team on tasks participants had completed—but it still failed to fetch the ball reliably on its own.
The central deployment choice is not just model strength: Anthropic says Fable 5 and Mythos 5 share an underlying model, but their safeguards govern which requests each can answer.
Opus 4.8 pairs a model update with effort controls and dynamic workflows: users can tune response depth, while Claude Code can tackle larger jobs with parallel agents.
Anthropic’s case is that Sonnet 4.6 brings broader coding, computer-use, and long-context capability to the Sonnet tier; Opus 4.6 remains its choice for the deepest reasoning tasks.
Google pitches Argon for long, multi-step professional work, but its first rollout is restricted to trusted cyber defenders while safeguards are strengthened.
Computer use moves into Gemini 3.5 Flash, letting agents work across browser, mobile, and desktop; Google calls it its best performance yet, but the captured benchmark graphic provides no readable results.
Google presents Gemini 3.1 Pro as a core-reasoning upgrade for difficult tasks, citing a new-logic benchmark result; it remains in preview while Google validates updates.
A one-line debugging request became a chain of browser tests and self-built instrumentation—Fable found ways to observe the bug without being explicitly told how.
The author’s central claim: Claude 5 Fable makes ambitious work possible with little input, but shifts the user from directing the process toward commissioning its outcome.
Choosing AI now means judging the model, the app, and the harness together: tool-equipped agents can take actions and complete multi-step work, not just chat.
Mistral presents ML4 as an open-weight, natively multimodal model for coding, agents and security. Its benchmark results are from a preview; weights and fuller technical details are still forthcoming.
Astra’s reported leap is from writing code to operating AI-engineering workflows; its ability to parallelize also makes the headline hourly cost conditional.
Z.ai presents GLM-5 as an open-source model for complex engineering and long-running agents, claiming best-in-class open-source performance in reasoning, coding, and agentic tasks.
