Evaluating Agent Performance: SWE-bench, WebArena, GAIA
Numbers on leaderboards are seductive and often wrong. Learn the big benchmarks, their leaderboard positions, their recently-exposed cheats, and how to run your own evals.
MMLU, GPQA, HumanEval, SWE-bench: The Core Four
Four benchmarks dominate modern AI announcements. Know what each measures, how, and where it breaks.
Autonomous Coding Agents 2026: Devin, Cline, OpenHands, and SWE-Bench Reality
What autonomous coding agents actually do well in 2026 — and where the demo videos lie.
Grok-Code — coding benchmarks and reality
xAI's code-specialist model ships strong benchmarks. Here is how it actually feels in a real IDE.
Reading Benchmark Cards Critically
MMLU-Pro, SWE-Bench, GPQA, ARC-AGI — vendor benchmark cards look authoritative. Most are gameable, contaminated, or measure the wrong thing. The vendor card is not the whole truth Every frontier model launches with a benchmark card — a wall of percentages on standard tests.
AI for Lab Notebook Weekly Summaries: Pattern-Spotting Across Daily Entries
Convert a week of bench notes into a structured summary that surfaces trends and questions worth chasing.
Medical Researcher in 2026: AlphaFold Changed Biology Forever
Literature review in minutes, protein structures on demand, AI-proposed drug candidates. The discovery cycle has compressed — but the human posing the question still sets the direction.
Why Agents Fail (and How to Notice)
Agents fail in weird, quiet, expensive ways. Learn the six failure modes, the warning signs, and the simple habits that catch problems before they compound.
The Full Agent Landscape in 2026
The agent market matured fast. Here's the field map — frontier labs, frameworks, browsers, local stacks, benchmarks — so you can pick the right tool without shopping by hype.
Multi-Agent Orchestration: Planner + Executor + Verifier
One smart agent is fine. Two agents checking each other's work is better. Master the canonical orchestration patterns: planner/executor, judge/worker, debate, and swarm.
AI Agents as Your Personal Trainer
An AI agent can build, track, and adjust a workout plan that learns what you actually do.
AI art conservator treatment proposal letter
Use AI to draft a treatment proposal letter from an art conservator to the work's owner.
AI fashion designer supplier production spec sheet
Use AI to draft a production spec sheet for a fashion supplier covering measurements, materials, and finishing.
AI For Fitness And Nutrition Planning
AI can build you a workout plan in 60 seconds. Here's how to know when that plan is reasonable, and when it's a recipe for an injury or an eating disorder.
Science Lab Design With AI: Inquiry That Hits the Standard
Designing an inquiry-based lab from scratch takes hours. AI can generate lab outlines — with materials, procedures, data tables, and analysis questions — that a teacher can verify and adapt in minutes.
Emergence, Capability Forecasting, and Safety
Emergent abilities make AI both more exciting and more dangerous. How do labs forecast what the next model will do — and what happens when they are wrong?
AI Benchmarks: What 'GPT Beats Human' Really Means
How AI labs measure progress and why the headlines often mislead.
AI and Jury Duty Prep: What to Actually Do at 18
AI explains jury duty so the first summons doesn't catch you unprepared.
Multimodal AI Trade-offs: Vision, Audio, Video
Multimodal AI handles images, audio, and video. The performance varies by modality and the cost varies dramatically.
AI and Claude 4: Anthropic's Latest Beast
Claude 4 (Opus and Sonnet) leads coding benchmarks and has a 1M-token option.
llama.cpp: The Engine Underneath Almost Everything
Ollama, LM Studio, and most local-model apps are wrappers around llama.cpp. Knowing what it actually does — and how to drop down to it — pays off when defaults are not enough.
Moonshot AI and Kimi: Meeting the Long-Context Specialist From Beijing
Moonshot AI is a Chinese frontier lab whose Kimi assistant pushed million-token context into the mainstream. Here is who they are, why their work matters, and where they sit on the global model map.
Agent Benchmarks: WebArena, GAIA, OSWorld
LLM benchmarks are about single answers. Agent benchmarks measure multi-step real-world task completion. Very different beast.
Why You Should Not Trust the Leaderboard
Leaderboards are compelling. They are also deeply misleading. Here is a checklist for real skepticism. In reality, leaderboards hide a stack of choices that can swing the ordering: prompt wording, sampling settings, number of attempts, which subset of the benchmark is reported.
Capability Evaluation vs. Safety Evaluation
Asking 'can the model do it?' and 'will doing it cause harm?' are different questions. Both matter.
Safety Evaluations: What Gets Disclosed
Labs run dangerous-capability evaluations before release. Which results go public, and which stay private? The line is moving, and it matters.
Chemistry and AI: Balancing Equations and Staying Safe
Chemistry equations are puzzles. AI can balance them instantly. But the lab is still physical - and AI cannot smell danger.
Cursor Rules: Teach The Editor Your Repo
Cursor works better when repo rules explain architecture, commands, style, and boundaries before the agent edits.
AI for Research Postmortems on Failed Aims: Documenting What Didn't Work
Document failed experiments and aims so the lab learns and reviewers see honest progression.
