- Agent Cost Attribution: Finding Where the Tokens Went
A single monthly API bill tells you that agents are expensive. It does not tell you which feature, which customer, or which retry loop is responsible. That gap is fixable.
AI · August 19, 2026 - Human-in-the-Loop Agents: Where to Put the Approval Gate
Approve everything and the agent is a slow autocomplete. Approve nothing and you have handed irreversible actions to a system that can be talked into things.

Fixed thinking budgets gave way to effort levels, and the default is rarely the right setting. Here is how the dial behaves and where each level actually belongs.
AI · August 19, 2026 - Retrieval Metrics: Measuring the Half of RAG That Fails
When a RAG system answers badly, the retrieval usually failed before the model ever spoke. Measuring generation quality alone hides that entirely.
AI · August 19, 2026 - Reward Hacking: When Models Optimize the Wrong Thing
A system trained on a proxy will exploit the gap between the proxy and what you meant. Here is how reward hacking shows up in practice and how to catch it.

Autonomy is a permissions problem, not a model problem. Here is how to design approval tiers, scope credentials, and set the boundary between act and ask.

Every model you build on will be retired. Here is how to structure prompts, evals, and contracts so the migration is a two-day task instead of a two-month fire.

Distillation transfers capability from a large model to a small one for a specific task. Here is how to build the pipeline and where the quality actually lands.
AI · August 18, 2026 - Embedding Model Migration: Re-indexing Everything, Carefully
A better embedding model is available. Switching means re-embedding your entire corpus, because vectors from two models are not comparable in any way.
AI · August 18, 2026 - LLM Determinism: Why Temperature Zero Is Not Reproducible
You set temperature to zero and got two different answers to the same prompt. That is expected, and understanding why changes how you test and cache.
AI · August 18, 2026 - Needle in a Haystack Tests: What They Do Not Tell You
A model finds a planted sentence in a million tokens with near-perfect accuracy. That result is widely quoted and says almost nothing about real long-context work.
AI · August 18, 2026 - Online Evals: Measuring an LLM App in Production
Offline evals tell you whether a change broke your test set. Online evals tell you whether it broke real users. Most teams only build the first and wonder why quality drifts.
AI · August 18, 2026 - Prompt Compression: Sending Less Without Losing Meaning
Long prompts cost money on every call and degrade accuracy. Here is how to shorten them systematically, what compresses safely, and what must stay verbatim.

Generate an answer five times and take the most common result. Here is why that beats one careful attempt on some problems, and where it wastes money.
AI · August 18, 2026 - Agent Replay and Checkpoints: Resuming Instead of Restarting
An agent fails at step forty of fifty. Restarting means paying for forty steps again and hoping the non-deterministic parts land the same way. Checkpoints make that unnecessary.
AI · August 17, 2026 - AI Agent Cost Per Task: The Number That Actually Matters
Cost per token tells you nothing about whether an agent is economical. Here is how to compute cost per successful task and what usually dominates the total.

Neoclouds, reserved capacity, and spot GPUs all price the same silicon very differently. Here is how compute leasing works and which contract shape fits which workload.

Idle accelerators are the largest waste in most AI infrastructure. Here is how scheduling, queueing, and workload mixing lift utilization without hurting latency.

Your evaluation suite reports 94% and has for months. The number is stable, your users are not happier, and the two facts are related.

Prompt tweaking without measurement is guessing. Here is how to build the evaluation set before the feature, what to score, and how to keep evals honest as they grow.

Using a model to grade another model is now standard practice. Here is where it agrees with humans, the biases that skew it, and how to build a judge you can trust.

Every LLM eval rests on a set of examples someone decided were correct. Build that set badly and every number you produce afterwards is confidently meaningless.

Splitting an agent into a planner and an executor makes long tasks tractable and adds failure modes. Here is when the separation helps and how to handle replanning.
AI · August 17, 2026 - Tool Result Caching: Not Fetching the Same Thing Twice
Agents re-fetch the same file, re-run the same query, and re-search the same term within a single run. Caching those results is the cheapest speedup available.

Vision-language models turn images into tokens a language model can read. Here is what that architecture means for accuracy, resolution limits, and cost per image.
AI · August 17, 2026 - Agent Memory Consolidation: Deciding What Is Worth Keeping
An agent that remembers everything is an agent whose memory is useless. Consolidation is the process of deciding what survives, and it is where most memory systems fail.
AI · August 16, 2026 - Subagent Architecture: When to Split One Agent Into Many
Delegating to subagents buys you parallelism and a clean context per task. It also buys you coordination overhead and a harder debugging story. Here is where the trade lands.

Agents fail in ways logs do not capture. Here is what to trace, which signals predict failure, and how agent observability differs from ordinary application monitoring.

Vendors quote extraction accuracy without saying what they measured. Here is how to define the metric for your documents and what a realistic number looks like.
AI · August 15, 2026 - Context Poisoning: When a Bad Fact Contaminates the Run
One wrong retrieved chunk or one bad tool result enters the context, and every subsequent step reasons from it. The agent gets more confident as it gets more wrong.
AI · August 15, 2026 - The Reflection Pattern: Agents That Check Their Own Work
Asking a model to critique and revise its output improves some tasks and wastes tokens on others. Here is where reflection earns its cost and how to bound it.

Users extract system prompts routinely, and no instruction reliably prevents it. The question is what you put there that you cannot afford to lose.

The prompt drives more behaviour than any function in your codebase and often lives in a string literal nobody reviews. A registry fixes the parts that matter.
AI · August 14, 2026 - Agent Token Budgets: Capping Spend Without Cutting Off
A max_tokens ceiling stops an agent mid-sentence. A task budget tells it how much it has so it paces itself and lands the plane. The difference matters more than it sounds.

Multi-agent systems fail at the seams. Here are the handoff patterns that survive production, what each one costs in tokens, and how to tell when one agent was enough.

A large share of AI workloads have no user waiting on them. Batch endpoints price that patience at roughly half, and most teams never use them.
