Three ways to keep an agent's untrusted code off your host kernel — and why the right choice is a triangle of compatibility, cold-start speed, and operational weight, not a security ranking.

The bottleneck in a coding agent isn't the smart model deciding what to change. It's the dull mechanical work of writing that change to disk correctly — and that's a different model entirely.

Storing embeddings at full precision is a tax most RAG systems don't need to pay. Binary cuts memory 32x — and the trick that buys the quality back is cheaper than the savings.

The async coding agents have all converged on the same shape — a cloud VM that clones your repo, runs the tests, and opens a PR. So the thing you're actually choosing isn't the coder. It's the harness and who reviews the flood.

DeepSeek's October paper shows vision tokens can carry roughly 10x the text of text tokens at ~97% fidelity — which quietly reframes long context as a compression problem, not a capacity one.

A long-running agent fails when its window fills with stale tool output. Anthropic ships three levers for that — and the trap is treating them as competitors instead of a division of labor.

The two best coding agents disagree at the architecture level on how to find the right code. One builds a vector index of your repo; the other threw the index away and runs grep. The split is about freshness, not accuracy.

One paradigm has an agent write a Python snippet as its action; the other has it emit a structured JSON tool call. The 20% accuracy gap everyone quotes is real — but only on the tasks where it applies.

They both promise durable, resumable agents — but one is a place to run code and the other is a way to structure it. Confusing the two is how teams end up with neither.

The eval-tooling field just split into three camps and lost two players to acquisition in a single month. Pick on philosophy and independence, not the feature grid.

The B200's headline 5-6x throughput jump is two different upgrades wearing one number — bigger HBM and FP4 compute — and which one matters depends entirely on whether your workload is memory-bound or compute-bound.

A Stanford/SambaNova method called ACE lets an agent get better by editing its own context instead of its weights — and the trick is to grow that context, not compress it.

An LLM judge scores the final answer. For a multi-step agent, that signal is sparse, late, and easy to fool — a broken trajectory can still land on a right answer, and you'd never know.

Three platforms that look like competitors but optimize for different primary jobs, with lock-in profiles that diverge sharply once you read the fine print.

A deep agent is not a new model or a framework breakthrough — it's four cheap, known ingredients that let a plain tool-calling loop survive a long task instead of drifting.

Most teams buy one vector store and call it 'memory.' It solves exactly one of the four problems — which is why the agent still loses the thread and repeats yesterday's mistake.

Is it cheaper to run an open model on your own GPUs than to call an API? The deciding number isn't the token price — it's how busy the GPU stays.

Both spend N times the inference to make a model smarter. The difference is how they choose the winner — and that choice decides which tasks each one can help.

Everyone has GRPO now — it ships in every training library. The scarce, defensible input in agent training turned out to be the environment, and it looks suspiciously like your eval.

Search teams optimize NDCG. RAG teams copy them — and measure the wrong thing. For a pipeline that hands the whole top-k to a generator, recall is the floor and rank position is a second-order correction.

The chunk that matches your query best is rarely the chunk that answers it. Small-to-big retrieval fixes that — here's how the three patterns differ and which to reach for.

The list reads like a model-safety checklist. Read it again: most of the ten are not the model misbehaving — they're your architecture trusting the model too much. Agents make exactly those entries worse.

The Apps SDK isn't a rival to MCP. Your ChatGPT app IS an MCP server — the only proprietary part is how ChatGPT renders and discovers it.

OpenAI shipped a drag-and-drop agent canvas in October, then posted its deprecation notice eight months later. The part that survived tells you which layer to build on.

Offline evals ask whether the agent matched a known answer. Online evals can't — there is no answer. Treating them as one pipeline with one metric is the mistake that lets agents pass every test and still fail in production.

The July 28 release candidate rips out sessions and the initialize handshake, deprecates Sampling and Roots, and adds MCP Apps — the clean break agent developers have to plan for.

Most teams assume LangGraph's checkpointer already makes their agents crash-proof. It doesn't — and the gap is architectural, not a missing setting. Here's exactly where it ends and where Temporal begins.

LangChain 1.0 reduced the agent to two lines and moved everything interesting into hooks. The quiet consequence: supervisor, swarm, and reflection stop being architectures and become middleware you stack.

Three different things hide under "structured output": valid JSON, the right shape, the right values. Each method buys you a different one — and none of them buys the last.

A tool description isn't documentation — it's a prompt you pay for on every call and the model rereads more carefully than your system prompt. Treat it like one, and stop shipping your whole API as tools.
