What Are AI Agents? How They Work (With Business Use Cases)

An AI agent is an AI system that pursues a goal: it plans, uses tools like APIs and a browser, acts, checks the result, and repeats until the goal is met — unlike a chatbot, which answers one prompt and stops. Here is how AI agents work and where they fit in a business.

Anthropic Built Claude a Science Workbench — and Gave It a Fact-Checker

Anthropic's Claude Science is a beta research workbench with 60+ science skills and a reviewer agent that flags bad citations and untraceable numbers.

AI Model Pricing Explained: Input, Output & Cached Tokens

AI model pricing is charged per token and split into input, output, and cached rates, with output typically 3 to 5 times pricier than input and cached input around 90% cheaper. This explainer decodes the dual rate, prompt caching, batch and long-context tiers, and shows a worked cost example.

SWE-bench Pro vs SWE-bench Verified: Why These AI Coding Scores Don't Compare

SWE-bench Verified and SWE-bench Pro are two different AI coding benchmarks — Verified is an easier 500-task subset, Pro is a harder, contamination-resistant test. The same model can score 80.6 on Verified and 55.4 on Pro, which is why the two scores cannot be compared.

Closed vs Open-Weight AI Models: How to Actually Choose (2026)

Closed vs open-weight AI models come down to who holds the weights. This decision grid weighs cost, control and data residency, security, ecosystem, and performance parity, then maps concrete usage profiles to the right choice.

What Is an Agentic Coding Model? (And How It Differs From a Chatbot)

An agentic coding model is an AI that plans a task, uses tools, drives a terminal or browser, edits a real codebase across many steps, and self-corrects until the goal is done. A chatbot answers one prompt; autocomplete finishes a line. This is the founding distinction of the 2026 coding-model era.

Anthropic's Claude Sonnet 5 Puts Near-Opus Agents in the Cheap Seats

Claude Sonnet 5 is Anthropic's midsize model, released June 30, 2026. It scores 63.2% on SWE-bench Pro — near Opus 4.8's 69.2% — at $2 per million input tokens, 40% of the flagship's price. Now the default for free and Pro.

Claude Fable 5 Is Back: Anthropic Redeploys After US Export Controls Lift

Claude Fable 5 is back. Anthropic began redeploying its most capable model on July 1, 2026, after the US lifted export controls on June 30. Access returns on Claude Platform, Claude.ai, Claude Code and Claude Cowork, with a new safety classifier.

OpenAI Launched GPT-5.6 Sol — Then Let Washington Decide Who Gets It

OpenAI unveiled GPT-5.6 (Sol, Terra, Luna) on June 26, 2026, then limited the launch to roughly 20 government-approved partners at the Trump administration’s request — the first frontier AI model released under a US government-managed access list.

Google's DeepMind Brain Drain Just Sped Up: Two More Gemini Researchers Reportedly Headed to Anthropic

Bloomberg reports Jonas Adler and Alexander Pritzel, both key Gemini contributors, are set to leave Google for Anthropic — the fourth and fifth senior AI departures in roughly six days. Here is why it matters.

An Open-Source Pipeline Re-Scanned Dormant Genomes — and Found 241 New Rare-Disease Diagnoses

Talos, an open-source automated genomic reanalysis pipeline, surfaced 241 new rare-disease diagnoses in 238 people from 4,735 undiagnosed patients (a 5.1% additional yield) — by re-interpreting old genomes, not autonomous AI diagnosis.

Anthropic Accuses Alibaba and Qwen of an Industrial-Scale Effort to Distill Claude — What the Letter Actually Says

Anthropic accuses operators tied to Alibaba and Qwen of the largest known distillation attack on Claude — 28.8M exchanges via ~25,000 fraudulent accounts. It's an accusation in a Senate letter, not a lawsuit.
