Get started with OpenAI GPT-5.5, GPT-5.4 models, and Codex on Amazon Bedrock (3 minute read)

Amazon Web Services launched OpenAI's GPT-5.5 and GPT-5.4 models, along with the Codex coding agent, on its Bedrock platform, offering pay-per-token pricing without per-developer seat licenses. GPT-5.5 is available in US East (Ohio) for demanding workloads while GPT-5.4 is available in two US regions for better price-performance, with Codex—used by over 4 million developers weekly—integrated into popular IDEs like VS Code and JetBrains.
DigitalOcean Serverless Inference: A Deep Dive (9 minute read)

DigitalOcean launched Serverless Inference, a fully managed API platform offering access to over 30 foundation models across text, code, vision, image, video, and speech generation through a single API key with pay-per-token pricing and no minimum commitments. The OpenAI-compatible service includes advanced features like an Inference Router for automatic multi-model selection, prompt caching, built-in tools for knowledge retrieval and web search, and integrates directly with DigitalOcean's existing infrastructure including databases, object storage, and VPCs under unified billing.

Building an Enterprise-Grade SQL Platform on Kubernetes using Crossplane and Azure PostgreSQL (7 minute read)

A Kubernetes-native enterprise SQL platform uses Crossplane to provision and manage Azure PostgreSQL Flexible Server with declarative APIs, implementing multi-region active–passive architecture with private networking, DNS abstraction, and automated infrastructure composition. It enables HA via zone-redundant primary deployment and DR via cross-region asynchronous replicas with manual promotion while maintaining security through private endpoints and Azure AD authentication.
How we reduced core unit boot time from hours to minutes (8 minute read)

Cloudflare slashed server boot times from four hours down to three minutes across nearly 2,000 core servers after a routine firmware update caused machines to waste roughly 20 minutes probing each failed network boot interface before finding the correct one. The fix involved reprogramming the boot sequence to declare the correct network interface upfront, though implementation required workarounds for lazy-loaded UEFI data structures, vendor-specific naming inconsistencies, and immutable firmware settings that initially blocked configuration changes.
The Inference Tax: How Prefix-Aware Routing Eliminates the Hidden Cost of LLMs at Scale (13 minute read)

DigitalOcean partnered with Inferact to slash AI inference costs by up to 4x through prefix-aware routing and caching in vLLM, recovering up to 340 GPU-hours daily at 10 million requests by eliminating redundant computation of shared prompt prefixes. The optimization, built for DigitalOcean's Dedicated Inference platform, will roll out to all Serverless Inference customers in the coming weeks, leveraging AMD Instinct MI325X GPUs' 192GB HBM3 and NVIDIA H200's 141GB HBM3e to maintain substantially larger KV cache capacity and boost cache hit rates from ~25% to 75%+.

Resources & Tools

Headroom (GitHub Repo)

Headroom, an open-source compression tool, reduces AI agent token usage by 60-95% by compressing tool outputs, logs, RAG chunks, and conversation history before they reach LLMs while maintaining answer accuracy. The Python library works as a proxy or MCP server with any OpenAI-compatible client and has already saved over 60 billion tokens across its user community.
Scrapling (GitHub Repo)

Scrapling, a new open-source Python web scraping framework, was released with adaptive parsing that automatically relocates elements when websites update and built-in bypassing of anti-bot systems like Cloudflare Turnstile. The library supports everything from single HTTP requests to full-scale concurrent crawls with pause/resume functionality, requires Python 3.10 or higher, and claims significant performance advantages over popular alternatives in benchmarking tests.

Reliability Engineering for Air-Gapped Systems (5 minute read)

SLIs and SLOs in air-gapped, high-security systems require shifting observability to on-prem operators through dashboards, alerts, runbooks, and status pages, since developers lack runtime access. Reliability is achieved via structured self-service tooling, error codification, and ownership transfer to reduce detection and resolution time under strict isolation constraints.
Prompt → Secure Infrastructure: The Claude Code DevSecOps Shift on AWS (10 minute read)

Claude Code Security and Agent Teams are positioned as a continuous AWS-aware security layer for Terraform environments, using multi-agent parallel audits, IaC graph reasoning, and AWS MCP integration to detect IAM, network, and secrets drift before production. The workflow emphasizes PR-based auto-fixes, cross-region audits, and scheduled compliance checks to replace slow manual security reviews with ongoing automated enforcement.
