OpenAI open-sourced its Codex Security CLI in late July, and it emits SARIF — the same format GitHub's Code Scanning tab already reads. Here's the copy-paste pipeline that turns an AI scanner into a real, blocking PR gate, plus the one setting that stops it from crying wolf.

The gap between 'send' and the first visible token is where users decide your product feels fast or broken. Here's the end-to-end SSE path — backend to browser — and the buffering bug that silently un-streams it.

One command starts the server. The VRAM formula tells you which open models you can actually run on a founder budget — and the cost-per-million math tells you when self-hosting beats just paying the API.

Astra proved ten open math problems and handed over Lean 4 certificates a machine can check without trusting the model. You don't need a frontier lab to copy the pattern — here's the builder's version, with code, for making any long-running agent's output verifiable.

The transparency rules went live on August 2, 2026. If your product talks to users or generates media, you now owe two things: a disclosure users can see, and a mark machines can read. Here's the disclosure snippet, the C2PA signing command, and the deadline you can still miss.

DeepSeek retrained V4-Flash and shipped it under the same name and endpoint this week — zero migration, and zero warning that your production behavior just moved. Here's how to detect a swap you don't control, before your users do.

The store you pick today is the store you'll outgrow. Put a two-method interface in front of it now, and moving from a file to a service becomes a migration you run in an afternoon — not a rewrite you dread.

OpenAI turned ChatGPT into a login button on August 2. The decision pieces tell you whether to add it; none show you the wiring. Here is the whole flow — authorization-code + PKCE against auth.openai.com — with the redirect, the token exchange, and the exact three claims you get back, in one Node file.

Elicitation used to be a local-server luxury. The stateless core and Multi Round-Trip Requests finally let a remote server pause a tool call, ask the user for structured input, and resume — here's the code.

Your provider invoice is one number. Cost per 1K tokens tells you nothing about which customer, feature, or job is bleeding money. Here's how to group per-call token spend into per-task cost with OpenTelemetry's GenAI conventions and Langfuse — with the exact attributes and code.

Every agent-memory tutorial names a different set of things "memory." There are only two axes underneath, and once you can see them the vendor menu stops being confusing.

The embeddings API is so cheap that a rented GPU almost never wins on raw cost — you need tens of billions of tokens a month before an L40S undercuts a $0.02/M API. Here's the worksheet that finds your exact crossover, plus the three reasons that aren't cost at all.

A rented H100 costs the same whether it runs flat-out or sits idle. A per-token API costs nothing when no one's calling it. That single difference — fixed vs variable — is the whole decision, and it has a number.

The memory tool is now GA on the Messages API — no beta header. But it ships no database: Claude only *asks* to read and write files, and your code does the work. Here's the whole loop, plus the one line of validation that keeps it from reading your secrets.

The $3/M list price isn't what you actually pay. Kimi K3's cache-hit input is $0.30/M, and with the reported ~92% cache-hit rate the effective input cost lands near $0.52/M — but only if you structure prompts so the cache actually hits. Here's the copy-paste setup and the one ordering rule that decides your bill.

On September 1, 2026, Sonnet 5 moves from $2/$10 to $3/$15 per million tokens — a flat 50% rise that hits base input, output, every cache tier, and the batch rate identically. Here's the exact math, why caching won't save you, and the four levers that actually do.
