The rumors were strong that February would have a number of model releases and OpenAI and Anthropic both did not disappoint with the release of Opus-4.6 as well as Codex-5.3.
Engineering leaders as well as founders/CEO of organisation should in my humble opinion read the subtext carefully of Greg Brockman's tweet as well as others such as Aaron Levie of Box, Addy Osmani of Google Deepmind on how software engineering processes need to adapt to take advantage of the increasing capabilities of models particularly coding models and 'compound' their engineering efforts

1 | via Boris Cherny, creator of Claude Code at Anthropic I'm Boris and I created Claude Code. I wanted to quickly share a few tips for using Claude Code, sourced directly from the Claude Code team. The way the team uses Claude is different than how I use it. Remember: there is no one right way to use Claude Code -- everyones' setup is different. You should experiment to see what works for you!
1. Do more in parallel
Spin up 3–5 git worktrees at once, each running its own Claude session in parallel. It's the single biggest productivity unlock, and the top tip from the team. Personally, I use multiple git checkouts, but most of the Claude Code team prefers worktrees --  |
2 | Chamath Palihapitiya Opens AI Software Factory to Public Use The venture capitalist's company 8090 launched the tool 18 months ago to modernize outdated enterprise software. Software Factory blends human teams with AI agents for zero-drift code that auto-updates docs, maps old codebases, and automates patterns via Assembly Lines. One early user swapped a $15 million SaaS vendor for a cheaper in-house option, easing vendor lock-in and maintenance costs.
18 months ago, I started 8090 with the goal of replacing/rewriting all the legacy software in the world with modern, useful alternatives.
We are making so much progress with many Enterprise customers that starting tomorrow, we will release our “Software Factory” into the wild SOFTWARE FACTORY | Build something that lastsSoftware Factory is an AI-native SDLC orchestration platform where PMs, designers, engineers and QA collaborate to ship high-quality software.  |
3 | Google just launched Project Genie to Ultra subscribers two days ago. 48 hours later, Alibaba matched it with zero licensing fees. Genie 3 runs at 24fps, 720p, for “a few minutes.” LingBot-World runs at 16fps, 480-720p, for 10 minutes. Genie 3 requires a $250/month Google AI Ultra subscription. LingBot-World costs zero dollars and gives you the weights. Robbyant (Ant Group’s robotics division) built LingBot-World on top of Alibaba’s Wan2.2 video model, Three days from announcement to full open-source release. Weights, code, technical paper, everything. GitHub - Robbyant/lingbot-world: Advancing Open-source World ModelsAdvancing Open-source World Models.

FWIW, I'm trying out tasklet.ai albeit in a deliberate and slow manner
Not endorsing it at this point in time but sharing incase others who might be interested are willing to kick its tires. Do read the X handles of the founder and various team members and get a sense of its capabilities as well as restrictions vis-a-vis openclaw
Think of it as as a form of openclaw (though they have their own agent harness) with lots of security layers built by an ex-Firebase (acquired by Google) team with decent VC funding

Hi! I'm Michael Lehenbauer, engineer #2 at Firebase. Among other things, I invented Firebase Database security rules (I'm sorry!). Lately I've been working with Andrew Lee (co-founder of Firebase) and a handful of other Firebase teammates on Tasklet.
Tasklet makes it trivially easy to automate your business processes with autonomous AI agents that can talk to your email, calendar, bug tracker, and basically everything. I also use it to run my personal life (plan hikes, find local events / activities to attend, find shopping deals, etc. ).
Similar to Firebase we're trying to empower users with powerful capabilities behind a ruthlessly simple UX. Would love for folks to give it a try and be brutally honest in your feedback.

2 | via Simon Willinson OpenAI just released a new macOS app for their Codex coding agent. I've had a few days of preview access - it's a solid app that provides a nice UI over the capabilities of the Codex CLI agent and adds some interesting new features, most notably first-class support for Skills, and Automations for running scheduled tasks.
Introducing the Codex app—a powerful command center for building with agents.
Now available on macOS.

3 | Pinging those members in this group who understand the dark arts of video editing to kick the tires and tell us plebians if this YC backed product befits the hype. Happy also to get comments from the founder of HeyEddie Shamir Alibhai who I hope reads this group more frequently than I'm assuming he does --- It lives in your browser and helps you go from a sea of raw footage (talking heads, screen recordings, screenshots, B-rolls) to a great video in seconds.

1 | Anthropic Releases Claude Opus 4.6 AI Model Anthropic launched Claude Opus 4.6, its upgraded smartest model featuring improved planning, longer agentic task sustainment, reliable operation in massive codebases, self-error detection Claude Opus 4.6 targets developers and knowledge workers with top scores in agentic coding (65.4% on Terminal-Bench 2.0), software engineering (80.8% on SWE-bench), and tool use (91.9% on TAU-bench), often beating rivals like Claude Opus 4.5 and GPT-5.2. New features include a beta 1 million token context window, agent teams for parallel work in Claude Code, and integrations with Excel and PowerPoint for tougher office tasks. Staff like Boris Cherny praise its intelligence and endurance, with early testers hailing it as a 'true collaborator' already transforming video production and code analysis.
I've been using Opus 4.6 for a bit -- it is our best model yet. It is more agentic, more intelligent, runs for longer, and is more careful and exhaustive.
For Claude Code users, you can also now more precisely tune how much the model thinks. Run /model and arrow left/right to |
2 | GPT‑5.3-Codex, the most capable agentic coding model to date. The model advances both the frontier coding performance of GPT‑5.2-Codex and the reasoning and professional knowledge capabilities of GPT‑5.2, together in one model, which is also 25% faster. This enables it to take on long-running tasks that involve research, tool use, and complex execution. Much like a colleague, you can steer and interact with GPT‑5.3-Codex while it’s working, without losing context. GPT‑5.3‑Codex is our first model that was instrumental in creating itself. Introducing GPT-5.3-CodexGPT-5.3-Codex is a Codex-native agent that pairs frontier coding performance with general reasoning to support long-horizon, real-world technical work.  ttps://x.com/sama/status/2019474754529321247
I’ve had early access to GPT-5.3-Codex.
It’s a fucking monster. Runs can go 8+ hours... and I come back to working code + live deployments. It’s significantly more autonomous than Opus 4.5. But it’s not all positive. My review: 
shumer.dev
My GPT-5.3-Codex Review: Full Autonomy Has ArrivedThe first coding model I can start, walk away from, and come back to working software. Judgment under ambiguity + validation/tests changes everything.
It's Christmas morning: @OpenAI and @AnthropicAI shipped new models on the same day!
We tested GPT 5.3 Codex vs. Opus 4.6 head-to-head. Verdict: the models are converging. Here’s what we found  every.to/p/codex-vs-opus

3 | Factory has open-sourced its' internal lint rules -- Our internal lint rules are now open source, featuring 23+ custom rules we use to guide droids at Factory. These rules cover file organization, React patterns, testing, error handling, API conventions, and more. Every rule is 100% droid-generated and includes detailed Markdown docs. While this isn't meant to be imported as-is, we hope it inspires you to build custom linting rules tailored to your own codebase. Take what works, ignore what doesn’t, and tweak as needed. You can leverage the docs as building blocks to suit your specific framework or language.

5 | A lot of sub-text in these tweets. For members of this group who are engineering leaders, lots to ponder about as to the various things which lead to 'agent readiness'

Every team shipping AI-assisted code at scale needs new norms around quality gates, observability, and ownership.
Regardless of which model or toolchain you use, this is one of the most practical frameworks I've seen for adopting agentic development.
