Quick summary Target bounded decisions: Jev returns typed answers rather than free-form prose. Separate interface from speculation: the article distinguishes public behaviour from unconfirmed internals. Validate correctness: typed output still needs evaluation and calibrated thresholds. Control consequential use: log outcomes and review uncertain cases. How Jev works starts with a simple observation: most software does […]
Quick summary Evaluate actions and answers: polished text can hide a failed workflow. Check three surfaces: the outcome, tool-use path and final external state. Combine suitable graders: deterministic checks, rubrics and human review. Learn from failures: turn traces into regression cases and measure cost and constraints. AI agent evaluation starts with a simple reality: an […]
Quick summary Separate latency measures: first-token delay differs from later token cadence and total time. Inspect preparation work: retrieval, queueing, prompt processing and networking contribute. Measure the bottleneck: avoid treating every delay as model slowness. Reduce avoidable work: bound retrieval, reuse stable prefixes and tune serving policy. Time to first token (TTFT) explains a familiar […]
Quick summary The article examines an AGI claim: it connects reported benchmark performance with the compute needed to obtain it. Separate scores from practical value: demanding evaluations do not by themselves establish affordable everyday usefulness. Autonomy creates additional costs: a persistent workflow needs clear goals, spending limits and ways to stop. Treat headline claims critically: […]
AI agent frameworks, including Vercel AI SDK, LangGraph, CrewAI, AutoGen and LangChain, are often grouped together. However, they do not solve the same problem. Choose from the architecture you need to build rather than searching for one “best” framework. This comparison uses the supplied five-tool overview as a research prompt, not as a source of […]
An agent evaluation flywheel can expose the path an AI agent took to reach an answer. A final-answer score can hide wrong tools, needless retries, weak evidence, or a failure to adapt when new information appears. That creates a practical question: what should change next? This post turns that diagnosis into a five-stage operating model. […]
Trajectory evaluation shows how a final answer can look perfect while the agent behind it has already failed. Imagine an agent that tells a support team: “The customer record has been updated.” The sentence is clear and reassuring. However, the trace may show a different story. It may select a search tool instead of an […]
Contextual Retrieval addresses a common RAG failure: a system can return a chunk that looks relevant while still missing the information the user needs. The usual culprit is lost context: a sentence survives chunking, but the document, product, customer, date, or definition that makes the sentence meaningful does not. Anthropic’s answer is Contextual Retrieval. In […]
