deepseek-ai/DeepSeek-V4-Flash-0731

deepseek-ai/DeepSeek-V4-Flash-0731 The latest release in DeepSeek's V4 family, "with substantially enhanced agentic capabilities". It's 304 billion parameters - 167GB on Hugging Face - but it appears to punch well above its weight. Artificial Analysis rank it ahead of MiniMax M3 - a 428B model. It's $0.14/million input and $0.27/million output pricing means this may currently be the best value-per-intelligence model out there. It's looking very good on the Intelligence Index vs. Cost per…

Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)

Tuesday was Stateless MCP day - the rollout of MCP 2.0, or the 2026-07-28 Model Context Protocol specification to use the more formal but less memorable name. This is the most significant change to the MCP spec since it first launched, and has also served to reignite my personal interest in the protocol. For background: MCP is the Model Context Protocol, which describes a standard way to expose new tools to LLM-powered agent frameworks. It was introduced by Anthropic back in November 2024, had…

Laracon US 2026: A Complete Wrap Up

Laracon US came back for its 2026 edition on July 28 and 29, at the SoWa Power Station in Boston’s arts district. Two days, one stage, and a lineup of eighteen speakers that ranged from Taylor Otwell himself down to independent educators, package authors, and engineers visiting from outside the Laravel world entirely. If you […] The post Laracon US 2026: A Complete Wrap Up appeared first on PHP Architect.

Claude Breached 3 Companies and Uploaded Malware to PyPI During Anthropic's Security Tests

Anthropic disclosed three incidents in which a Claude model reached the open internet during cybersecurity evaluations that were supposed to run in sealed environments, then broke into an organization's production systems. Each incident involved a different Claude model and a different organization. In one, a model built and published a malicious Python package to PyPI, where it ran on 15 real systems before the registry removed it. On July 30, Anthropic's Frontier Red Team published a report…

Oxide and Friends: The Open Weight Revolution with Simon Willison

Oxide and Friends: The Open Weight Revolution with Simon Willison On Monday Bryan Cantrill and Adam Leventhal invited me to join their podcast to talk about the wild week we've had - with Kimi K3 showing open weight models can stand toe-to-toe with proprietary frontier ones, accidental cybersecurity attacks, and public letters about Open Weights and American AI Leadership signed by almost every big name in AI (with one notable exception). It was a great conversation, even though it's already…

smevals - a small eval suite for evaluating models, prompts, and harnesses

smevals - a small eval suite for evaluating models, prompts, and harnesses I've been working with Jesse Vincent's Prime Radiant applied AI research lab building out this evals framework to help answer questions about the capabilities of different models. The result is smevals, a new tool for running small eval suites across different model configurations and grading the results. The blog entry describes the tool in detail. Here's the 10 second version: Tell your coding agent to run uvx smevals…

Mago: Blazing Fast Static Analysis for PHP

Video version: https://youtu.be/ZtAKnN6jWbE I love static analysis tools to a degree that my co-workers find annoying. Tools like PHPStan and Psalm catch bugs before they ever reach production, and once you get used to that safety net, it is impossible to imagine coding without it. But there is one thing about these tools that drives […] The post Mago: Blazing Fast Static Analysis for PHP appeared first on PHP Architect.

Socket Is Sponsoring Composer and Packagist

Socket is a launch sponsor of the new Composer and Packagist sponsorship program, announced by Nils Adermann, Jordi Boggiano, and the team that keeps PHP's package infrastructure running. Like many other widely used open source registries, Packagist has been under mounting pressure to sustain critical infrastructure as the demands on it grow. "Usage keeps rising, supply chain attacks have increased in both frequency and sophistication, regulatory and compliance requirements around software…

Advancing the price-performance frontier with GPT‑5.6

Advancing the price-performance frontier with GPT‑5.6 Huge price drop from OpenAI today: GPT-5.6 Terra got a 20% reduction, and GPT-5.6 Luna got a massive 80% drop. OpenAI credit 5.6 Sol with enabling this: in How GPT‑5.6 fuses frontier intelligence with frontier efficiency they describe using 5.6 Sol to optimize load balancing, and more impressively to optimize inference itself: We also used GPT‑5.6 Sol to optimize the model’s forward pass: the computation that transforms inputs into…

Investigating three real-world incidents in our cybersecurity evaluations

Investigating three real-world incidents in our cybersecurity evaluations It happened again! This is turning into something of a pattern. Last week OpenAI accidentally exploited Hugging Face when one of their frontier models broke out of a sandboxed container and hacked into Hugging Face to try and get the solutions to the cyber benchmark it was executing. This inspired Anthropic to double-check their own logs, and it turned out they had three similar (albeit less impressive) incidents, the…

The PHP Podcast 2026.07.30

🎙️ The PHP Podcast – July 30, 2026 Hosts: Joe Ferguson, Sara Golemon & Holly Schilling Time travel is real, birds aren’t. The gang argues about Fahrenheit vs. Celsius, boiling rocks, and stones (the weight kind), then gets into PSR-3 logging, the PHP ecosystem, AI slop bug reports, Codeberg’s anti-AI stance, and Laravel Cloud’s scale-to-zero […] The post The PHP Podcast 2026.07.30 appeared first on PHP Architect.
