How do we know OpenAI's Astra math proofs are real?On 1 August 2026 OpenAI announced its next model family, Astra, by publishing ten new results in mathematics and theoretical computer science, each on a problem open for at least a decade, and each sh1Aug 6 · 7 min readtech4biz-solutions.hashnode.dev
Who verifies the verifier, and why AI eventually needs a floor it cannot argue withThere is a question in AI right now that a whole research field has walked into from one side, and that we keep meeting from the other. The field is asking whether we can trust a model to judge anothe21KAug 3 · 7 min readtech4biz-solutions.hashnode.dev
Add More Error Correction to a Quantum Computer and It Can Get Worse, Not Better. A quantum computer's raw qubits are unreliable, error-prone, noisy. To get one qubit you can actually trust, a "logical" qubit, you have to bundle dozens or hundreds of the noisy physical ones togetheJul 16 · 8 min readtech4biz-solutions.hashnode.dev
Ask Your AI Agent the Same Question Twice. If the Answers Differ, No Amount of Fine-Tuning Fixes That.A language model is probabilistic. Ask it the same question twice, worded exactly the same way, and you can get two different answers back. That's not a bug. That's what the model is. For a chatbot, nJul 15 · 6 min readtech4biz-solutions.hashnode.dev
AI Can Migrate Your COBOL to Java. It Can't Prove It Didn't Break Anything. We Built the Part That Does. Every bank, insurer, and government system running on a mainframe today is sitting on COBOL that nobody wants to touch and nobody can afford to leave alone. AI coding agents have made the migration itJul 14 · 8 min readtech4biz-solutions.hashnode.dev
