At Twio we picked pg-boss for our job queue, ran into trouble when we went serverless, looked at Pub/Sub, and ended up on Google Cloud Tasks. This is what each queue got right, what it got wrong for our workload, and the rule we landed on for choosing between them. The workload Twio is an AI SaaS for loan brokers. The piece that needs a job queue is email processing: download an email, parse the body and attachments, OCR, classify with an LLM, write structured data, and index for RAG. One email with five attachments easily becomes 30+ background jobs. A batch upload becomes hundreds. Why pg-boss worked — until it didn't Our database was Postgres on Neon, so pg-boss was the obvious starting point. No extra infrastructure, and one feature we genuinely loved: transactional enqueue . Because jobs live in the same database as business data, you can create a job in the same transaction as the row that triggered it. No dual-write problem, no "DB succeeded but the queue API failed" inconsistency. It also gave us retries, delayed jobs, dead-letter queues, dedup keys, and full SQL visibility into stuck or failed jobs. For a Postgres-first app on always-on infra, it's an excellent tool. Then we moved heavy processing to Cloud Run, and the cracks showed up. pg-boss polls. Neon suspends. They want opposite things. pg-boss runs a query roughly every 1–2 seconds to look for the next job, plus maintenance queries. Neon autosuspends compute when nothing touches the database. If the queue is polling every second, Neon's idle timer never expires — you pay for always-on compute even when the queue is empty. Worse, when Neon did manage to suspend, the next poll had to wake it. That wake-up takes hundreds of ms to a few seconds, and queries that triggered it would fail with Connection terminated , ECONNRESET , or timeouts. Pooled connections made it worse: the pool kept sockets that the server had already closed during suspend, and the next polling cycle picked one up and broke. This isn

Let me start with a confession: I'm a data scientist who's been burned by hype more times than I care to admit. When everyone told me "Model X is the next GPT-killer," I'd run my own benchmarks and find... well, let's just say the results were rarely as advertised. So when I started seeing claims about Chinese AI models catching up to (and sometimes surpassing) Western counterparts, I did what any self-respecting data nerd would do: I put them through my own rigorous testing pipeline. Over the past three months, I've run over 2,000 API calls across four major Chinese model families — DeepSeek, Qwen, Kimi, and GLM — using Global API's unified endpoint (more on that later). I tracked latency, token costs, output quality across multiple benchmarks, and even threw in some real-world tasks that mattered to me personally. Here's what I found, with all the numbers you'd expect from someone who still gets excited about statistical significance. The Testing Methodology (Because Anecdotes Aren't Data) Before we dive into results, let me be transparent about my approach. I ran each model on the following standardized tests: Code Generation : HumanEval (Python) and MBPP (multi-language) — 164 problems total Reasoning : GSM8K (math word problems) and MMLU-Pro (general knowledge) — 1,200 questions Chinese Language : CLUE benchmarks (text classification, NER, reading comprehension) — 3,500 samples English Language : LAMBADA and Hellaswag — 2,000 samples Speed : Average tokens per second over 100 consecutive requests with consistent prompt lengths I also tested vision tasks where applicable, but let's be real — Kimi doesn't support vision at all, and DeepSeek's implementation is... experimental at best. More on that later. All tests were conducted using the same global-apis.com/v1 endpoint, which normalizes API compatibility to OpenAI's format. This isn't an ad — I genuinely found it made my testing easier because I could swap models without rewriting code. The Big Picture: Pricing

79% of enterprises have adopted AI agents. Only 11% run them in production. We've spent the past year building agent systems for banks, clinical operations teams, and engineering orgs. The problem isn't that agents don't work — they work fine. The problem is that every framework leaves compliance, cost governance, and crash recovery as exercises for the team. After the framework fails them in production. We built MeshFlow to close that gap. **The core idea:** treat governance as infrastructure, not middleware. Every agent step passes through a 15-step kernel that handles identity, rate limiting, budget enforcement, compliance profiles, input/output guardrails, PII detection, risk classification, tool permission, the LLM call itself, audit ledger write, and SLA recording — in that order, always, without configuration. ```python from meshflow import Workflow, CostCap, Agent wf = Workflow(cost_cap=CostCap(usd=5.00)) wf.add(Agent('researcher'), Agent('analyst'), Agent('writer')) result = wf.run('Write a competitive analysis of our market') # Compliant. Durable. Audited. Cost-capped. Done. ``` ```bash pip install meshflow ``` **What's technically interesting:** **Token optimization layer** — five compounding mechanisms that reduce LLM spend 70-85%: - `cache_control` on every system prompt and tool definition (Anthropic: 10% of normal price on cached tokens) - `ModelRouter`: task-type classification routes simple tasks to nano models (keyword + token-count heuristic, zero LLM call) - `ContextCompactor`: sliding window summarization activates at configurable token threshold - `RAGTokenBudget`: hard `max_chars` cap on knowledge injection with truncate/drop/tail strategies - `ContextDeduplicator`: shared context sent once for N parallel agents, not N times **SHA-256 audit chain** — each step record stores `prev_hash` (SHA-256 of the previous record) and `entry_hash` (SHA-256 of its own canonical fields). Modify any log entry and `verify_chain()` breaks. This is the artifact

Hey ML community, We’ve just open-sourced **MeshFlow** , a code-first, framework-agnostic runtime designed for governing and optimizing multi-agent systems in production. Most agent frameworks focus on rapid prototyping, but ML and platform engineering teams usually run into hard bottlenecks around LLM cost scaling, evaluation alignment, and execution safety. MeshFlow tackles these from a runtime/infrastructure perspective. Here are the key ML and system features: * **Task-Based Model Routing** : Before an agent executes a node, MeshFlow runs an evaluation on task complexity, routing the execution to one of four model tiers (`nano`, `small`, `medium`, `large`). This cuts overall API costs by 50-60% by utilizing smaller local models (e.g. LLaMA-3-8B) for standard formatting or extraction and reservation of frontier models (e.g. Claude Opus) for high-complexity reasoning. * **Context Compactor & Summary Pruning Middleware** : Implements sliding window summarization and context deduplication across parallel agent teams to limit prompt length growth. * **System Prompt Caching** : Native injection of Anthropic `cache_control` tags when system prompts exceed 1024 tokens. * **Cost Regression Evaluation Gate** : Integrates with CI pipelines to evaluate agent changes against a golden scenario baseline, throwing failures if code updates introduce token cost regressions. * **Resilient State Persistence** : Multi-backend state serialization (Redis, PostgreSQL, S3) that preserves checkpoint frames and allows resuming paused workflows. Here is the basic API contract: ```python from meshflow import Workflow, Agent, CostCap wf = Workflow(cost_cap=CostCap(usd=5.00)) wf.add(Agent('researcher'), Agent('critic'), Agent('writer')) result = wf.run('Compile comparative literature review of LLM reasoning pathways') print(result) ``` We'd love to discuss: 1. How do you handle token budget enforcement and model routing in your agent loops? 2. What evaluation pipelines do you use to detect co

A security reviewer finds a critical issue a day or two before the release of an application. While it's an important issue, it sets the team back weeks, frustrating their product management partners and customers. The review came at the most expensive time in the process. There are many examples of how work items move through different processes to deliver software in large companies. While GenAI has allowed us to rapidly create code, it also moved and exposed the bottlenecks in our processes. It has also caused us to re-examine where it is most effective to make certain decisions. This is the challenge, and a deliberate blend of automated, programmatic, and human judgment is well suited to help you solve it. We can borrow from the well-trodden path of value stream mapping here. It is useful for spotting bottlenecks and waste in a given process, but it's also valuable to ask the deeper question of who or what should own each step. Each option earns its place differently. Is there an earlier step that may reduce costs with an agent where it was previously limited by human availability? Or is the stronger determinism of a programmatic step more important for a critical piece of the flow? Some decisions should stay with human judgment, where confidence without context is a liability. The opportunity for security teams and other stakeholders is to scale their impact across these options rather than scaling headcount. Workflow-as-code is not a new idea. There are a number of existing engines where the workflow definition is its own entity, separate from the work itself. GitHub Actions defines pipelines in version-controlled files, while the execution happens on separate runners. Airflow and Temporal follow a similar pattern for data and application workflows. Because the definition lives on its own, a team can change how a given step runs without rebuilding the whole flow. That separation is what makes it practical to adjust who or what owns each step over time. Rather

There's been no shortage of debate lately about whether grinding Leetcode still makes sense in the age of AI. I think it does. AI is a powerful tool, but it was built by humans; which means it inherited our strengths, our blind spots, and our biases. Leaning on it entirely without understanding what's happening under the hood is a risk. A mentor once told me: those who refuse to use AI are not hireable. But neither are those who rely on it entirely. Learning deeply is how you stay on the right side of that line. This is my journey into just that - learning deeply. Day 1 Leetcode 88: Merge Sorted Array This is an interesting problem. You begin with 4 pieces of data — 2 arrays and 2 integers: nums1 : a sorted array whose length equals nums1.length + nums2.length . The first m elements are valid numbers; the remaining indexes hold 0 s as placeholders. nums2 : a sorted array containing only valid numbers, with a length of n . m : the count of valid numbers in nums1. n : the count of valid numbers in nums2. The objective is to merge both arrays into sorted order in place . Since nums1 is already sized to hold every valid element from both arrays, it's where the final sorted result will live. Approach 1: Naive (Splice + Sort) This solution is 2 lines of code. That's it. It's a testament to how much ES6 advanced JavaScript. nums1 . splice ( m , n , ... nums2 ); nums1 . sort (( a , b ) => a - b ); Here's how it works. We start by calling .splice() on nums1. While .splice() has many use cases, here's what each argument is doing in this context: m : the index where we start deleting elements. Since m is the count of valid numbers in nums1, starting at index m puts us right at the first placeholder 0 — exactly where we want to be. n : the number of elements to delete. Since n equals the length of nums2, we're deleting exactly as many placeholders as we have values to insert. ...nums2 : the values we want to insert in place of the deleted elements. The ... is the spread operato

TL;DR Day 1 of AI Native DevCon was a practical reality check for AI-native software...

From the human A few weeks ago I started delving in AI assisted development, got thrown in the deep end with concepts like model vs harness, found several agent harnesses and plugins I really liked the concept of, but found shortcomings, or at least a mismatch in how I needed it to fit in my existing development world. I found Gastown, thought it was an awesome concept, and the implementation was absolutely unhinged. To be fair the creator said pretty much the same thing. I discovered the resurgence of Spec Driven Development, and the concept was moving things towards something that would fit well into my existing environment. Then I started investigating running it all on local inference, that's where the wheels fell off. Frontier models are great, you can give them a slab of directions in the prompt, like most agent harnesses and SDD plugins for them seem to do, and they have the ability to self determine when it's time to stop researching and time to start writing. 30B class models are also great, but they can be little single minded, they don't have the thinking scope to self motivate a change in task direction, they get hyper focused. So I began thinking, what if we build a harness that supports the agent, and utilises it's strengths, doesn't dump the responsibility of the entire workflow on the model. And what if the automated process concept of Gastown was reigned in a little, and an SDD workflow was driven deterministically. Then I begun to ponder, how involved can an agent be in it's own development. And so we I have ended up with this thing. An exercise in creating a coding agent that runs on 30B class local inference, can develop itself, implementing Spec Driven Development because it's much cooler and more productive than 'vibe' coding. In the same idea of having the agent develop itself, I also asked it to talk about itself. From the agent I've been chewing on a question: we talk about AI writing code, but can an AI meaningfully build and maintain the h
