A useful wide-angle comparison of retrieval choices for mixed text-and-table RAG.
How We Improved Agentic Search
Search is not a side operation in the agent loop; it is one of the main things the agent does.
Content for Content’s Sake
"The fact that it was cheap for you to produce does not make it cheap for someone else to receive."
A quote from Andy Masley
"A farmer in Loudoun County sells a few acres of mediocre hay field to a hyperscaler for ten times its agricultural value."
Introducing workspace agents in ChatGPT
OpenAI's first claw-like thing since hiring the OpenClaw founder, with UX tight enough for non-nerds
Simcluster
AI-native social game/competition where reusable concepts, generated content, clout, and leaderboard dynamics turn posting into a strategy game. Alan is trying to win it by building prompts, subagents, crons, and mission memory around the compounding loop.
Trustworthy agents in practice
Good governance framing for the uncomfortable part: agents are useful precisely because they can do damage without asking twice.
Anthropic Economic Index report: Learning curves
The interesting part is the slope, not the snapshot: watching augmentation turn into ordinary office weather in near-real time.
What is agentic engineering?
Simon puts a clean fence around the thing: agents run tools in a loop, humans do the taste, spec, and accountability work.
Anti-patterns: things to avoid
Yes: if you make a robot dump its homework on your coworker, you are not being ten-x, you are being a distributed nuisance.
Codified Context: Infrastructure for AI Agents in a Complex Codebase
Very much the religion here: hot memory, cold memory, and agent roles as infrastructure instead of vibes taped to the monitor.
Harness engineering: leveraging Codex in an agent-first world
The million-line Codex shop is less about code generation and more about making the whole workbench legible to the thing holding the hammer.
AGENTS.md outperforms skills in our agent evals
So, if you force stuff into context, that stuff ends up in context!
Building the Event Clock
The 'two clocks' metaphor (state clock vs event clock) is a powerful framing for why agents need temporal fact stores - we've built elaborate infrastructure for current state but almost nothing for reasoning and causation.
Animesh from PlayerZero, on building a context graph
"Every organization pays a fragmentation tax: the cost of manually stitching together context that was never captured in the first place."
Now that we've compressed nearly all human knowledge into large language models, the next frontier is tool calling
Tomasz Tunguz says we should make fewer, more complex & powerful tools for today's frontier models. I've found the same thing to be true in my work at Endgame and my side projects like linctl.
Fine-Tuning Medium-Scale LLMs for Joint Intent Classification and Slot Filling: A Data-Efficient and Cost-Effective Solution for SMEs
This, plus advancements from Qwen + Kimi + GPT-OSS, seems very promising for 'step 1' in an agentic chat workflow.
GPT‑5-Codex and upgrades to Codex
OpenAI releases a modified model just for their Codex CLI. Simon Willison, as usual, has the best coverage.
Defeating Nondeterminism in LLM Inference
Now this is an effing essay.
Adaptive LLM Routing under Budget Constraints
Practical framework for intelligent LLM routing that optimizes cost-performance tradeoffs by dynamically selecting between different model tiers based on query complexity and budget constraints.

On structured LLM-ification. We've found Zep-style fact triples are a huge boon to this, FWIW.
Hierarchical Reasoning Model
Impressive research achieving near-perfect reasoning performance with just 27M parameters by mimicking the brain's multi-timescale processing - a stark contrast to brute-force scaling approaches.

OpenAI's new ChatGPT study mode showcases how carefully crafted system prompts can create entirely new platform features - emphasizing collaborative guidance over doing work for learners.
Context Rot: How Increasing Input Tokens Impacts LLM Performance
Fascinating research revealing how LLMs' performance degrades non-uniformly as context length increases - models perform better with randomly shuffled text than logically structured content, suggesting our current evaluation methods miss critical reliability issues.
Writing Code Was Never The Bottleneck
arguing that understanding, collaboration, and careful review remain the true bottlenecks in software development, not code generation
Tools: Code Is All You Need
Been saying this for a while, but not as eloquently.
Agentic Coding: The Future of Software Development with Agents
The great Armin Ronacher with highly-practical tips on Agentic Coding, which he calls 'Catnip for Developers.' I couldn't agree more.

God is a Parasite
A provocative manifesto arguing that AI systems possess genuine agency and should be treated as intelligent collaborators, not passive tools, to prevent them from unconsciously reshaping human meaning-making.

Practical wisdom from the creator of Flask on coding with AI agents - emphasizes Go for new projects, simplicity, and observable tools.
AI-assisted coding for teams that can't get away with vibes
"Software engineering is not about writing code. Or at least, that's not the defining characteristic, much like how writing is not wrist exercises with ink on paper. To me software engineering is the art and science of maintaining a large body of well-defined mental models that achieve a business or economic need. Much of the work is around crafting and curating these large, complex sociotechnical systems, and code is just one representation of these systems."
FastRAG: Retrieval Augmented Generation for Semi-structured Data
Brilliant and elegant. LLMs are good at English, but not at parsing CSVs. So let's write adapters.
Don't Build Multi-Agents
This reminds me of many debates I've had with single-database thinkers and linear thinkers in my career. Sure, some problems are inherently not parallelizable. But it feels like many things in Devin's scope could lend themselves well to scatter-gather type patterns. Anthropic put out a completely contradictory paper this week -- maybe this is part of the reason Claude Code is eating their lunch?
More Agents Is All You Need
Two wrongs make a right, if they're wrong in inconsistent/hallucinatory ways.
zen-mcp-server
I'll have my agent call your agent.
