The $0 Bug That Cost Us $1,800 in API Calls
Last quarter our OpenAI bill went from $620 to $2,480 in 23 days. No new features shipped. No traffic spike. Zero error alerts. Deployment logs were clean. Just a number climbing in silence while five engineers stared at dashboards that gave us totals and nothing else. This is what we found. And why "cost monitoring" is completely the wrong mental model. The dashboard that answers the wrong question First thing I did was open the OpenAI usage dashboard. It showed me a total. A graph going up. A model breakdown. I knew we spent $2,480. I still had no idea which feature spent it, which service triggered it, or which user was responsible. The dashboard was answering "how much" while we were desperately asking "what caused it." Those are completely different questions. Almost every cost tool on the market only answers the first one. That distinction matters more than most engineering teams realise until they are staring at a bill like ours. Three features, zero visibility We had three features hitting GPT-4o: A document summariser, triggered manually by users An inline suggestion engine, triggered on keystrokes A batch report generator, triggered on export Any one of them could be the problem. Or all three. Or one specific tenant hammering one endpoint in a loop nobody noticed. Without attribution at the feature, service, and user level, we were just guessing. So I did what most engineers do: optimised the feature that felt most expensive. Added caching to the one that ran most often. Two weeks later the bill was still climbing. Guessing at cost problems without attribution data is exactly like debugging a performance issue without a profiler. You move things around and hope. 48 hours of real data A teammate dropped CostReveal in our Slack. I set it up that evening. The Node.js SDK wraps your existing provider calls. You instrument each one with a feature name, service context, and user or tenant ID. That is the entire integration for the base case: import { CostReveal

AI for API Design & Testing in 2026: Speakeasy vs Swagger AI vs Postman AI — I Built 3 APIs with Each
AI for API Design & Testing in 2026: Speakeasy vs Swagger AI vs Postman AI — I Built 3 APIs with Each API design is one of the most tedious parts of backend development. Writing OpenAPI specs, generating SDKs, testing endpoints, maintaining documentation — it's all hours of work that could be automated. In 2026, three tools are fighting for your API workflow: Speakeasy , Swagger AI , and Postman AI . I spent 4 weeks building the same REST API with each one, tracking time savings, code quality, and actual developer experience. Here's what actually happened. The Test Setup: Building a Real API I built a simple but realistic ecommerce API (GET/POST products, orders, user management) three separate times, measuring: Time to spec — writing the OpenAPI definition Time to SDK generation — generating client libraries Time to testing — setting up test cases and running them Documentation quality — readability, examples, completeness Iteration speed — how fast you can modify the API and regenerate everything All three tools were given the same requirements. Same laptop, same environment, same skill level (senior backend engineer). Speakeasy: The SDK Generation King Setup time: 8 minutes (CLI install, auth, first config) Learning curve: Low — clear docs, straightforward CLI Speakeasy is laser-focused on one problem: turning your API spec into production-ready SDKs. It generates TypeScript, Python, Go, Java, and more from a single OpenAPI definition. The Good SDK quality is exceptional. The generated TypeScript SDK was production-grade immediately — proper error handling, retry logic, request/response typing, retries built in. No cleanup work needed. Multi-language generation is instant. After writing the OpenAPI spec once, I had Python, Go, and TypeScript SDKs in < 2 minutes total. Each one was framework-idiomatic (using popular libraries in each language). Versioning is smart. Speakeasy automatically versioned SDKs and generated changelogs. When I modified the spec, it detect

Extracting and Organizing Content from Older Websites: A Solution for Structured Documentation Including Mouse-Over Images
Introduction Extracting data from older websites is a technical challenge that goes beyond simple copy-pasting. The example website provided illustrates this perfectly: its outdated design, reliance on mouse-over interactions, and lack of structured export options create a perfect storm of extraction difficulties. This article dissects these challenges and provides a roadmap for extracting both visible content and mouse-over images while preserving data integrity. The Core Problem: Legacy Technology Meets Modern Needs The website's URL parameters ( screen_width=0&screen_height=0 ) immediately signal a legacy system likely built for a bygone era of fixed-width displays. This design choice breaks modern scraping tools that expect responsive layouts. The mouse-over images, critical to the site's content, are dynamically loaded via JavaScript , meaning they don't exist in the initial page source. This requires simulating user interactions to trigger their appearance, a task beyond basic HTML parsing. Why Manual Extraction Fails Attempting to manually save images or copy text from this site is a losing battle. The mouse-over images, for instance, are not directly downloadable – they're embedded in JavaScript events. Even if you could save them individually, maintaining their association with the corresponding visible content would be error-prone and time-consuming. This method also fails to scale for larger websites with hundreds of such elements. The Technical Solution: A Multi-Pronged Approach Effective extraction requires a combination of techniques: Browser Automation: Tools like Selenium or Puppeteer can simulate mouse movements to trigger hover events, capturing both visible and hidden content. This method mirrors human interaction , ensuring all dynamic elements are revealed. Network Request Inspection: Analyzing the website's backend requests using browser developer tools can reveal direct URLs for mouse-over images , bypassing the need for hover simulation. This

**Quick Tip: How to Choose the Right Model for Slack AI Workflows in 2026
Quick Tip: How to Choose the Right Model for Slack AI Workflows in 2026 I've been running Slack-integrated AI workflows in production for about three years now, and the question I get asked most often is deceptively simple: "Which model should I actually use?" Back in 2024, the answer was easy — you picked GPT-4o and moved on. But in 2026, with 184 models accessible through Global API and price points ranging from $0.01 to $3.50 per million tokens, that decision has become a genuine engineering problem. Pick wrong and you're either burning budget or shipping a sluggish experience. Pick right and your CFO actually smiles at you. Let me walk you through how I think about this, what the numbers actually look like, and where I've landed after months of benchmarking across multi-region deployments. Why Slack Workloads Are Weird Most people underestimate what a Slack AI assistant needs to do well. It's not a chatbot. It's a latency-sensitive, always-on, context-heavy workload that has to feel native inside a chat client where users expect responses faster than they can refresh the channel. In my experience, the three constraints that matter most are: p99 latency under 1.5 seconds for the first token — anything slower and users start double-messaging 99.9% uptime across at least two regions — Slack itself is up, so your AI better be too Cost per active user per month under $0.40 — this is the line where finance stops asking questions If a model can't hit those numbers consistently, it's not viable, no matter how clever the benchmark scores look. The Pricing Landscape I Actually Use Here's the table I keep pinned in my team's documentation. These are the models we rotate between depending on the workload. I haven't changed a single number — these are the exact rates as of writing this: Model Input ($/M) Output ($/M) Context DeepSeek V4 Flash 0.27 1.10 128K DeepSeek V4 Pro 0.55 2.20 200K Qwen3-32B 0.30 1.20 32K GLM-4 Plus 0.20 0.80 128K GPT-4o 2.50 10.00 128K The spread is w

Stop letting the prompt be your state machine
Stop letting the prompt be your state machine You shipped an LLM feature six months ago. Now the same user input produces wildly different outputs depending on... nothing you can point to. Something in the sampling? The time the context filled up and a chunk got dropped? Nobody knows. This is what happens when the prompt becomes your runtime. The trap: the prompt as an accidental runtime Here is what the trap looks like in TypeScript: async function handleUserRequest ( input : string ): Promise < string > { const prompt = ` You are a helpful assistant. The user said: ${ input } Previous context: ${ someGlobalContext } Decide what to do, gather any information you need, format the response, and return it. ` ; return llm . complete ( prompt ); } The model is doing everything here: deciding the intent, gathering data, formatting output, choosing what to persist. That is a footgun. You handed the runtime to a stochastic function. Gartner attributes many failed agentic AI projects to unclear value and inadequate risk controls. Deterministic, testable workflows address both. The fix is not a better prompt. The fix is to stop using the prompt as an architecture. What "deterministic" can and cannot mean here Be honest about what you can and cannot control. You cannot control: the model's exact output. It is probabilistic by design. You can control: The shape of the output (structured output plus schema validation) The steps that run before and after the model call What data enters the model What happens when the output fails validation Whether a human reviews the result before it commits to anything irreversible Determinism here means: the same inputs, the same workflow steps, the same guardrails every time. Not the same tokens every time. That is a realistic and achievable target. It is also the thing teams skip when they are moving fast. Typed workflow steps around the model call Break the work into discrete typed steps. Each step has a clear input type and a clear output

What Recruiters Can't See On My GitHub
What Recruiters Can't See On My GitHub If you spend about 30 seconds looking at my GitHub profile, you might think I'm all over the place. React. Python. Healthcare. AI. Scrapers. Automation. Marketing tools. Job bots. Honestly, that's something I've worried about. I have over 100 repositories. Recruiters can see most of them, but not all of them. Some are private because they're client work. Some are private because they're unfinished. Some are private because they contain ideas I've spent years developing and I'm not quite ready to throw the blueprints onto the internet. From the outside, it can look random. But recently I realized something. All of those projects are solving the same problem. I hate repetitive work. My GitHub is here: https://github.com/ashb4 The Job Application That Broke Me I've applied to thousands of jobs over the years. Thousands. And one thing has always driven me absolutely insane. You upload your resume. Then the company immediately asks you to type your entire resume into fifteen different boxes. Your work history. Your education. Your skills. Everything. The computer already has the information. The resume is right there. Yet somehow I'm sitting on page seven of an application retyping information that already exists. It feels inefficient. It feels stupid. And most of all, it feels like a waste of time. Eventually I got annoyed enough to start building tools to help. Then I Noticed a Pattern At first I thought I was building unrelated projects. A job application helper. A content scheduler. A healthcare platform. An AI framework. A browser automation system. But when I stepped back, I noticed the same motivation behind almost all of them. Every project started with some version of: "There has to be a better way to do this." Take PostPunk. Most people see a social media scheduler. I see hours of repetitive posting that I never want to do again. I like creating content. I do not like manually posting the same content everywhere. So I buil
