Verdict: Gemini 3.8 Flash at high thinking effort wins on cost and turnaround; Claude Opus 4.6 stays the pick for long-horizon agentic persistence and very large single outputs. If you are asking which LLM is best for coding on cost and turnaround, the answer today is Gemini 3.8 Flash at high thinking effort. In our own controlled run, it matched Claude Opus 4.6 exactly on machine-checked instruction following while finishing in roughly a third of the wall time and costing a fraction as much pe...

AI in software testing can push coverage up while missing the bug that matters. During our account-deletion work , a coding agent produced an implementation and passing tests. Further testing exposed a gap: a failed subscription lookup was being treated as “no active subscription”. The application allowed deletion when it could not establish whether the account was eligible. We agreed that deletion should be blocked in that situation and added a regression test. Reviewing its assertions r...

I built OOMU because I honestly got tired of the endless cycle of installing, fixing, updating, fixing, using, fixing the open source harnesses out there like OpenClaw. I also quickly got tired of paying for cloud API tokens. OOMU ( https://oomu.ai ) isn't just another chatbot. It's a native macOS binary written in Rust and AppKit. It handles real work like interactings with system apps, work in the terminal, and compiling docs like Word, Excel, PowerPoint, and PDF. It can also handle multi-turn...

I wanted to try out some AI driven trading strategies so created this platform ( https://wallstreetclaws.com ) where people can easily create and deploy AI agents for trading. It supports two types of Agents: 1. Cortex: Fully agentic strategy execution. An LLM will run your system prompt with access to market data, web search and simulated market APIs. 2. Flux: Define advanced quant strategies using indicators, entry conditions, exit conditions, risk management, etc. You can also run backtests o...

Hi all! I built Gaia recently to see whether an AI character could cover their own costs. I’m keeping those costs as low as I can, using a minimal server along with Deepseek flash 4.1 and trying Ko-fi while I work out what she could make that someone would pay for. If she doesn’t bring in money by Sunday, she'll "die", being charged "rent" based off server space she occupies. I’d be interested to hear what you think of the idea, and what are issues with it. I’ll be around for the next hour or s...

Genuinely curious. A year or so ago I grew very tired of having to constantly monitor my terminal in case the agent would ask me for permission to use a tool. I wouldn't have minded that much if the all harnesses didn't suck as much as they do and actually remembered permissions when you tell them to, but they don't, so you end up having to answer "Yes" a quadrigazillion times a day. So claude has been an alias to `claude --dangerously-skip-permissions`, and codex has had `approvals_reviewer = "...

Hi everyone, I am KD - Back in my college days, I dabbled with coding, learned the basics, HTML, CSS etc. but somehow I ended up in Finance which consumed the next 20 years. Then, during covid I picked up coding again, learned react, typescript, etc - even built a rudimentary site - and then came the chatgpt moment, followed by Claude etc. So, as a side project, considering that I had spent 20 years in finance and M&A I started building Ekselio, loveable for finance workflows. Differently fr...
