The most interesting model comparison of 2026 isn't a benchmark table. It's a product exec quietly changing the question everyone asks about models — and getting a completely different ranking as a result. Claire Vo (founder of ChatPRD, host of the How I AI podcast) ran a head-to-head between OpenAI's new GPT-5.6 lineup (Soul / Terra / Luna) and Anthropic's Claude Fable and Sonnet. The result was an upset: the most theoretically intelligent model, Claude Fable, lost to the one she could actually collaborate with, GPT-5.6 Soul. Here's what that upset actually reveals. She killed "vibes" — then bet 70% back on her own taste Tired of vibe-checking, Vo built a real benchmark across the work she does every day: writing PRDs, prototyping apps, debugging multi-step code, and talking to an agent. Scoring had two layers — an LLM-as-judge (she picked the harshest judge, GPT-5.5) and her own hand-graded "taste test," where she clicked through every artifact and wrote notes. Then the key move: she weighted the final score 70% her taste / 30% the machine. "It's my show. I trust my own taste more." That's the first insight. Benchmarks are getting more rigorous, but the final call is still human taste. The point of blind testing isn't to replace taste — it's to force it to be honest . Cover the labels, react to the work itself, then put your judgment back at the center. Theoretically brilliant vs. practically effective On raw intelligence, Fable is elite. But Vo's verdict is the sharpest line on models I've seen this year: Fable is theoretically hyper-intelligent. Soul is practically effective. She describes Fable as "an engineer who has never met a human." Precise to the point of pedantry — it scores every risk, hardens every edge. In one case it hardened a tool-calling loop so tightly that only one specific model could run it at all. It optimized itself into a corner. Soul's edge was the opposite: it gets out of its own head. Same stuck problem — she moved it to Codex, said "sto

OpenAI is already shutting down ChatGPT Atlas, its browser that could do tasks for you on your behalf, less than a year after launching it. Atlas was announced in October, but as part of its wave of news about ChatGPT Work today, the company confirmed that it will be "sunsetting" Atlas and is targeting an […]

About two weeks after OpenAI's GPT-5.6 was caught up in regulatory drama - rolled out only to government-approved organizations during a "limited preview" period - the company has received the Trump administration's greenlight for a public rollout of the model. OpenAI CEO Sam Altman called it "the best model we have ever produced." To celebrate, […]

Three big AI IPOs are set to generate more value than all the U.S. VC-backed exits since 2000.

OpenAI found two unrelated bugs masquerading as one in ChatGPT's data infrastructure. Silent hardware corruption on one Azure host and an 18-year-old race condition in GNU libunwind's setcontext function with a one-instruction vulnerability window. The breakthrough came from switching to population-level crash analysis rather than examining individual core dumps. By Steef-Jan Wiggers

Experiments in using AI to build AI show that the future doesn’t just belong to the frontier labs.

Elon Musk's tech company released the newest version of Grok on Wednesday, promising a cheaper, more efficient alternative to other powerful AI models.

OpenAI is overhauling ChatGPT's voice mode with a new model that it says is more like "talking to another person." The new GPT-Live-1 is designed to interrupt you less and will also wait for you to continue speaking if you pause mid-conversation. During a press briefing, OpenAI research lead Kundan Kumar called GPT-Live-1 the company's […]

We’ve all been there: staring at a stack of printed lab results or a folder full of cryptic report_final_v2_NEW.pdf files, trying to remember if our cholesterol was higher or lower two years ago. For developers, this isn't just a filing problem—it's a data engineering challenge. In the world of healthcare, data is messy, siloed, and often locked in "unstructured" formats. To build a truly personal Electronic Health Record (EHR) system, we need more than just a folder; we need a RAG (Retrieval-Augmented Generation) pipeline that can parse PDFs, map them to the FHIR (Fast Healthcare Interoperability Resources) standard, and provide natural language insights. In this guide, we’ll leverage Unstructured.io , Milvus , and DuckDB to turn chaotic medical PDFs into a queryable, structured knowledge base. The Architecture: From Raw Pixels to Structured Insights Before we dive into the code, let’s look at how the data flows from a messy lab report to a structured answer. graph TD A[Unstructured PDF Reports] --> B[Unstructured.io Partitioning] B --> C{Data Split} C -->|Textual Context| D[Milvus Vector DB] C -->|Tabular Data| E[DuckDB Structured Storage] D --> F[LangChain RAG Engine] E --> F G[User Query: Is my glucose trending up?] --> F F --> H[FHIR-Formatted Response] Why this stack? Unstructured.io : The gold standard for handling "ugly" PDFs (tables, headers, and nested lists). Milvus : A high-performance vector database built for scale. DuckDB : Perfect for running complex analytical SQL queries on the extracted "structured" parts of our medical data. FHIR Standard : To ensure our data follows global healthcare interoperability rules. Prerequisites Make sure you have your environment ready: pip install langchain milvus unstructured[pdf] duckdb openai Step 1: Extraction with Unstructured.io Medical PDFs often contain complex tables. Standard PDF parsers usually fail here. We’ll use unstructured to partition the document into logical elements. from unstructured.partition.pdf

OpenAI Agents SDK 0.13 → 0.17: Three Breaking Changes You Will Hit The OpenAI Agents SDK moved from 0.13 to 0.17 in five weeks (April 9 – May 19, 2026). That's 19 releases, including three breaking changes. Two of them are silent — they change runtime behavior without raising an error at upgrade time. If you're running agents on 0.13.x, this is the migration guide you need before you upgrade. The Three Breaks Break #1: ModelRefusalError (v0.15.0) — Silent to Loud The change: Model refusals used to return empty-string output. Now they raise an exception. What this means: If your code treated refusals as output == "" or checked for empty responses, you were silent-failing gracefully. That behavior changed. A model refusal now raises ModelRefusalError and will crash your agent run unless you handle it. What you need to do: Register a "model_refusal" error handler before upgrading past 0.15.0: from openai.agents import Agent , RunConfig def handle_refusal ( error ): print ( f " Model refused: { error . reason } " ) return " Model refused to respond. Try rephrasing. " agent = Agent ( model = " gpt-4 " , tools = [...], ) config = RunConfig ( on_error = { " model_refusal " : handle_refusal , } ) response = agent . run ( " ... " , config = config ) Without the handler, you'll see: ModelRefusalError: model declined to process this request This is an intentional change — OpenAI wants refusals to be explicit, not silent. But it means your error handling has to change. Impact: Any agent that doesn't add a refusal handler will crash on a refusal. High-risk if your agents field user input directly. Break #2: Default Model Changed (v0.16.0) — Silent Model Switch The change: The default model switched from gpt-4.1 to gpt-5.4-mini . What this means: If you created an agent without explicitly setting model= , you were running on gpt-4.1. On upgrade to 0.16.0+, that same code silently switches to gpt-5.4-mini. This isn't just a version bump — gpt-5.4-mini ships with different defaults

OpenAI CEO Sam Altman has reportedly proposed giving 5% of the company’s equity to a U.S. sovereign wealth fund, reviving discussions about letting the public share in the financial gains from the AI boom.

OpenAI has floated giving the US government a 5 percent ownership stake as a way of easing tensions with the Trump administration and blunting mounting public backlash against AI, according to the Financial Times. CEO Sam Altman argued that giving the public a financial interest in the company would be the best way to share […]

We’ve all been there. You get a notification from your smartwatch saying your heart rate has been a bit funky, or your blood oxygen is dipping. Usually, we ignore it until it becomes a problem. But what if your personal AI was looking out for you? 🤖 In this tutorial, we are building an Autonomous Health Agent . This isn't just a notification bot; it's a proactive system that uses Playwright browser automation , OpenAI Function Calling , and Python to monitor your health trends and—if things look suspicious for three days straight—literally opens a browser and books a doctor's appointment for you. By leveraging Autonomous AI Agents and Playwright automation , we are moving from "Passive Monitoring" to "Active Intervention." This is the future of Health Tech Automation . 🏗 The Architecture Before we dive into the code, let's look at how the data flows from a "scary heart rate" to a "confirmed appointment." graph TD A[Wearable Data/Health Logs] --> B{3-Day Anomaly Check} B -- Normal --> C[Stay Healthy! 🟢] B -- Abnormal --> D[Trigger AI Agent 🤖] D --> E[OpenAI Function Calling] E --> F[Playwright Browser Automation] F --> G[Hospital Booking Platform] G --> H[Appointment Confirmation 🏥] H --> I[Notify User via SMS/Email] 🛠 Prerequisites To follow along, you’ll need: Python 3.10+ Playwright : The king of modern browser automation. OpenAI API Key : For the "brain" of our agent. A healthy dose of curiosity! 🥑 pip install playwright openai pydantic playwright install chromium 👨‍💻 Step 1: Defining the "Brain" (OpenAI Function Calling) We don't want the LLM to just "talk" about booking an appointment; we want it to actually execute the action. We'll use OpenAI's Function Calling to bridge the gap between text and code. import json from openai import OpenAI client = OpenAI () # Define the tool our agent can use tools = [ { " type " : " function " , " function " : { " name " : " book_doctor_appointment " , " description " : " Books a medical appointment based on department and s

A ChatGPT subscription starts at $20 a month and is one of the cheapest ways to run inference. OpenAI has also been fairly relaxed lately about third-party agents using them , which makes the deal even better for a lot of us. But a subscription can't be used as freely as pay-per-token access , and the providers police the difference. Anthropic recently narrowed its subscriptions to first-party apps; OpenAI has its own limits. Here's what will get you banned from an OpenAI subscription. Sharing your subscription A ChatGPT subscription is strictly personal. One subscription, one user. Sharing yours breaks OpenAI's terms of service. That also covers account pooling and account rotation, where several people share the same credentials to dodge rate limits. Running it in automation Automation (CI, runners, schedulers) should run on per-token pricing, not a subscription . Once a system calls the OpenAI API with your token while you're not in the loop, the usage stops being personal. No unattended production system should run on a ChatGPT subscription. Serving other users For now, you can point an autonomous agent like OpenClaw or Hermes at your ChatGPT subscription, as long as it only talks to you. The moment that agent starts chatting with other people, or serving them in any way, it turns into a team use case , and that inference should be paid per usage. Putting it in a commercial product Same logic here. Making an LLM call authenticated with an individual ChatGPT subscription inside a product you ship breaks OpenAI's terms. That access is subsidized, and reselling it in any form isn't what it's meant for. If you've built something just for yourself and you're the only user, you're probably fine. The bottom line A ChatGPT subscription is personal . Anything that stretches past personal use can get you restricted or banned. If you're not sure your usage counts, move it to pay-as-you-go. If you want to keep the subscription for your own work and fall back to per-token pr

The free open source agentic program is finally invading your phone.

Watching Elon Musk fulminate at Bill Savitt during Musk v. Altman - the case in which Musk sued Sam Altman and OpenAI instead of seeing a therapist about his AI failures - was a bit like watching a toddler have a temper tantrum at his nursery school teacher. Savitt's questions were "designed to trick me," […]

It was during a live client demo. The AI was mid-session. The user was answering questions. Everything was going perfectly. Then — this: "Sorry, there was an error processing your request. Please try again." The client looked at us. My manager looked at me. I looked at my laptop and wanted to disappear. The Investigation First thing I checked: OpenAI dashboard. No failed runs. Nothing. I checked our server logs. There it was: run_timeout — after exactly 60 seconds But here's the thing — the run wasn't failing. It was just slow. OpenAI was still processing. Our backend gave up at 60s. OpenAI finished at 87s. We quit too early. Why Does This Happen? The longer a session gets, the more history OpenAI has to process. Early in a session: 3–5 seconds. Mid-session (10+ messages): 30–50 seconds. Long sessions: 60–90+ seconds. Our hardcoded limit of 60 seconds wasn't matching reality. The Fix Step 1: Made the timeout configurable via environment variable. # .env OPENAI_RUN_TIMEOUT_MS=150000 Step 2: Updated the polling loop to use it. const TIMEOUT_MS = parseInt ( process . env . OPENAI_RUN_TIMEOUT_MS ) || 150000 ; const TERMINAL = [ ' completed ' , ' failed ' , ' cancelled ' , ' expired ' , ' requires_action ' ]; while ( ! TERMINAL . includes ( runStatus . status )) { if ( Date . now () - startTime >= TIMEOUT_MS ) throw new Error ( ' run_timeout ' ); await new Promise ( r => setTimeout ( r , 1000 )); runStatus = await openai . beta . threads . runs . retrieve ( threadId , run . id ); } Step 3: Deployed. No more errors. Lessons Learned Always handle ALL 5 terminal states — not just "completed" Never hardcode timeouts for AI workloads — they vary by session length Your error logs and OpenAI dashboard together tell the full story What's Next I'm exploring runs.stream() — streaming responses in real time, no polling, no timeouts. Will write a follow-up once it's in production. Have you hit this before? How did you handle it? Drop it in the comments.
