i don’t love that anthropic and openai are starting to release models much later publicly than they do privately to employees, friends, and influential people.
as these models become increasingly capable, it creates a dangerous precedent. how is it going to play out when a handful of individuals and companies had gpt 10 five months before you?

Peter Gostev: My view of: Fable 5 vs GPT-5.6-Sol. They are not easy models to compare, these are my vibes - take them as you will.
My overall feel is that Fable is a 'wise owl' who is very thoughtful and very well spoken, GPT-5.6-Sol is like a rottweiler who will grab the problem by the

dax: i've never hyped a model release, we're generally conservative with how we use these things
but gpt-5.6 has had a massive impact on our team, we're using 5x the tokens as we used to
it's not even smarter than fable or anything, but it's just so reliable and fun to use
it surely doesnt

I really enjoyed this piece. It’s a rare article that explains, at an intuitive level, how “self-evolving agent products” actually work today.
My takeaway is this: a system needs to build an effective data feedback loop from real user interactions by controlling context; move beyond static benchmarks by creating accurate end-to-end behavior evals that can become automated optimization loops for agent iteration; and use the model’s own reasoning and coding capabilities to drive product improvements at scale (i.e. automatically cluster large volumes of production logs to identify systemic failures, then have AI write the patch, run tests, and submit the PR on its own.)
Through mechanisms like these, developers can build agent systems that can self-repair and continuously improve.
Hopefully one day I’ll be able to share my learning and observation like this one too.
Amjad Masad: Many are asking how Replit is improving so rapidly—we closed the loop and the agent is self-improving.

Mitchell Hashimoto: I had early access to 5.6/Sol for ~month. Sol is my default. It is faster, plans/judges just as good as Fable, and I think produces better overall work. I’ll reach for Fable still for highly targeted debug or performance work with clear reward functions.

an interesting property of traditional capitalism is that businesses often have to pick between scale and culture

Daniel Priestley
Socialists imagine a class struggle. In their made-up fantasy the CEO is in competition with low level workers, the wealthy entrepreneur is stealing from the underpaid nurse.
In reality, workers do not compete vertically they compete horizontally.
Entrepreneurs compete with entrepreneurs. Investors outbid each other. CEOs are benchmarked against other CEOs. Nurses are hired from a pool of nurses. Etc.
The CEOs pay has no correlation to the entry level workers. The Football star on £300K a week isn’t linked to the person selling drinks in the stadium. A biotech entrepreneur raising VC capital isn’t paid relative to a cleaner.
What is linked is the demand and supply dynamic of each role.
If a company places an ad for a qualified truck driver and 150 people apply for the role, then the company knows it does not need to increase wages for that role. If the company has an open role for months, it is forced to look at the compensation package.
Same for a CEO. A board representing shareholders would like to hire a CEO for a lot less if they could. Their dream scenario would be to hire a CEO who brings in institutional investors, attracts top executives, drives innovation and growth, keeps margins steady and is a good public face for the business even under pressure. It turns out there aren’t a lot of these people looking for work and if you want one you have to pay more than other companies are offering.
The class struggle isn’t vertical it’s horizontal. CEOs are in competition with CEOs. Retail workers are in competition with retail workers. Demand and supply dynamics set the price.
Sure you can say that a CEO want’s profitability and would like wages to be lower BUT it’s not up to the CEO - demand and supply tension sets the price of workers. An Airline like RyanAir would like free pilots if they could get them but they can’t… so they pay the market rate.
The reason incomes are rising at the top and falling at the bottom is not class warfare. It’s technology and globalisation.
Technology makes basic jobs simple, remote or fully automated. At the same time tech makes executive roles more leveraged, more important and more valuable.
A CEO used to run a smaller organisation. Today a CEO who’s 2% better on a $5B company is generating $100M more. Seems sensible to try and pay a few million to get $100M.
Globalisation has put workers from all over the world in completion with each other - downward pressure on wages. Globalisation has given CEOs more market opportunities to explore - upside opportunity to unlock.
The rich are not very interested in buying houses that poor people own. The poor are not buying up the homes the rich want. They are separate groups living separate lives. Try finding the genuinely rich people whose strategy is to hoard normal residential homes - it barely exists as a thing. About 85% of landlords are people who own 1-4 properties. Super-landlords (100+ properties) are 0.2% of landlords and own a tiny fraction of the 30M homes in the UK… and they’re heavily taxed.
Class warfare isn’t real. It’s an imagined war in the minds of socialists.
Demand and supply dynamics are real. To the degree it is measured in class, it’s a horizontal competition not a vertical one.
Gary Stevenson: There's a difference between normal people spending money and really rich people spending money. And it explains why our economy is failing.

We stand at a critical crossroads in the debate over AI governance in the United States, and it feels like we are inching closer to a very serious battle over whether or not open source models will even be allowed in an environment where a new de facto licensing regime has been taking shape.
Lacking formal congressional statutory frameworks or clear administration rules (like the diffusion rule revision), we appear to be left with a sporadic, arbitrary, non-transparent process for model review. The fiction of “voluntary” agreements hangs over this debate, and some large model developers are already showing an incredible willingness to bend over backwards to accommodate national security-related officials / orders that the rest of us are not privy to. It's a very opaque process. And those model developers are expected to play ball with those officials, or else their models get pulled from the market or held up for long periods. Or they will lose any government procurement contracts they have. There is nothing “voluntary” about it when that Sword of Damocles hangs in the room.
As this mess worsens, at some point the question of how to handle open source models will come into sharper focus because it will have to. I've even heard some rumors lately that something may be coming from the admin on this front to address this.
Needless to say, if this informal new AI model review regime expands and takes on more pre-vetting characteristics / requirements, it is hard to see how open source players could comply with such quasi-licensing of AI models. Specifically, if this ambiguous new regime is accompanied by a general presumption of ‘restrict-until-permitted,’ then that would spell doom for open source. That is a very dark path for our country.
Worse yet, of course, would be a move by national security officials to more directly restrict open source models and capabilities. If that happens, then we would be right back in the thick of a Clipper Chip-like battle along the lines of what we saw in the late 1990s. That is a much darker path for America.
Meanwhile, open source developers have no “golden shares” or other goodies to offer the government to make their problems go away.
Let’s be clear: If our government takes the dark path, it will become the single most important battle over computational freedom of modern times. It is time for people to make a stand in defense of open source before it is too late.

Ex-NVIDIA engineer who built Unsloth explained RL, kernels, reasoning, quantization, and agents in 2 hours 42 minutes - better than $5000 fine-tuning bootcamps.
pick the base model -> write triton kernels for 2x faster fine-tune -> quantize to 4-bit -> run GRPO/DPO -> ship a reasoning model on your single GPU.
That loop is why Unsloth is the default way to fine-tune Llama, Qwen, Gemma, and Phi on hardware you already own.
Unsloth + Triton kernels + 4-bit quantization + GRPO/DPO + single-GPU fine-tuning - that's the stack.
Watch and save it, then fine-tune your first model tonight.

🚀 We open-sourced Sighthound today.
Sighthound is a Rust-based static vulnerability scanner for source code. It runs locally or in CI, uses Tree-sitter parsers, and supports pattern-based detection plus taint flow analysis. It also comes with all it's rulesets with no paid account or signup needed.
https://github.com/Corgea/Sighthound/
Why build another static scanner in 2026?
Semgrep and OpenGrep are useful, but we kept running into a few constraints: the OCaml core raises the contribution bar for many developers, adding language support is not as simple as we wanted, and some higher-signal rule content in the ecosystem sits behind accounts or paid offerings.
We wanted something fast, inspectable, easy to extend, and fully open.
A few implementation details:
- Rust binary for local and CI use
- Tree-sitter parsing
- Pattern matching and taint analysis by default
- Cross-file taint propagation and dependency tracking
- Parallel file discovery and scanning
- Text, JSON, and CSV output
- Rules written in RON and deserialized into typed Rust structs/enums
- MIT licensed
Current support includes Python, JS/TS, Java, Go, C#, HTML, PHP and Ruby.
It focuses on source-code vulnerability classes like command injection, SQL injection, XSS, path traversal, code injection, unsafe deserialization, and crypto issues. It is not a secrets scanner.
We're still have a lot of work to getting to where we want it to be so, we would love the community to test it, break it, report issues, and tell us where it falls short. PRs for rules, language support, fixtures, and false-positive tuning are very welcome.
Competition is great for consumers and developers.
It's great to see Grok 4.5 and Muse Spark 1.1 both be Opus level viable models. Hopefully Google launches Gemini Pro 3.5 soon too.
Having 5 labs compete vs. 2 will keep all of our AI subscription plans alive and prices reasonable :)

Open source powers everything in America. We must fight any and all attempts to restrict it in the age of AI.
We must never surrender to the short-sighted safetyists and hawks.
Open source is the entire reason American tech dominates across the globe. If you can't see this it is largely because it is invisible but your blindness to it is no excuse. You are protected by a smoothly running invisible shield the powers everything and that shield is open source.
It powers every major cloud. The router in your house. Your phone. The servers at your work. The NASDAQ and NY Stock Exchange. Radar systems. Just about every website you know and love. The SaaS you're reading this on right now, called X.
Restricting it in the AI era is idiotic, short-sighted and foolish at an almost mind boggling level. It is civilizational suicide.
Take Microsoft. In the early days of Linux they pushed hard against it and called open source "communism" and "cancer." Imagine if their short-sighted stupidity had won the day? Their Azure cloud now predominately runs Linux.
They would have destroyed *their own* future revenue with their foolishness and greed.
In this fight we must never surrender.
We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills.
We shall never surrender!

Most people know I usually prefer OpenAI's models over Anthropic's.
But for this generation, it's the opposite.
That said, a larger pretrained base + OpenAI's RL stack will create an absolute beast of a model, so I expect OpenAI's next release will bring me back.

Lawrence Jang: guys I just cancelled my Claude plan I don’t know what happened
Some praise and feedback about OpenAI's launches:
1. More than any other lab, OpenAI has the opportunity to make working with agents mainstream. ChatGPT with images, live voice, browser/computer use, and plugins for all your favorite apps is the closest thing to working with a super-capable coworker who can learn and do any white collar work.
2. I didn't get to test GPT 5.6 weeks early, but after a day of testing, I think my best compliment is: "It's got that dog in it."
It basically never gives up, no matter how complicated a task you give it, and is very reliable thanks to browser use and the other features above.
It does seem to burn more tokens than GPT 5.5, although maybe I don't have the right settings. I'm using Sol on High.
3. GPT Live is arguably a more important launch than today's updates for the masses.
We've been talking to each other using voice for 100K+ years, while the keyboard and mouse weren't introduced until the 1950s/60s. Maybe voice will soon make these two tools look like old computer punch cards.
Also, the best thing about GPT Live is that it lets me pick the intelligence level. I care about latency, but I care more about talking to someone who's smart and gets me.
Speaking of which, it'd be cool if I could have a live conversation with ChatGPT voice and see the tasks it's doing for me.
Ok, now for some constructive feedback:
4. I think the ChatGPT Work vs. Codex thing is confusing. It raises questions like, "So developers aren't working?" and "What if I'm using it to plan my vacation, is that work?"
I think the whole thing should just be called ChatGPT, Codex, or ChatGPT Codex and there should be no tabs or toggles. IMO, Codex is not that complicated for a normie to understand and use. You're still chatting, except now it can do stuff.
The sooner this is all unified, the better.
5. I'm very confused about when I should use Sol, Terra, or Luna, and whether I should set effort to Light, Medium, High, etc.
There's nothing in the UI that walks through what to use when. I understand power users might want these options, but regular people will just get confused.
6. Another thing that's confusing is tasks vs. chat. Ideally, your past chats should still be there in the left nav, except now those chats can do something with plugins. Normies will not understand why their chat history is suddenly harder to find.
7. When I was a PM, I loved building with a community of trusted users who gave me feedback along the way before general availability. But I also tried to make it transparent to users what qualifications were needed to join this community. I don't mind that OpenAI is doing the former, but the latter is not clear at all.
Thanks for listening. Codex has changed how I work and for that I'm very grateful.
OpenAI: Introducing ChatGPT Work, a new agent in ChatGPT powered by Codex and GPT-5.6.
It can take action across your apps and files, stay with a project for hours if needed, and turn a goal into finished work.
It’s a whole new way to get work done.

@philipkiely broke down exactly how he does it, his full writing process, the hindsight 20/20 lessons, and how one article drove 500K+ views
This [technical] Write and Learn workshop #5 is part of our Independent Studies series, hosted with @swyx @KernelLabs_ai.
All sessions are recorded. Our next one will be in two weeks :)
i am really sad about this and very grateful for all fidji has done for openai, and even grateful for her friendship and who she is as a person.
we all wish her the best for a speedy recovery. this sucks.
Fidji Simo: Today, I shared with the OpenAI team that I have decided to leave my full-time role at OpenAI and transition to being a part-time advisor.
Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived with for seven years. During that

easy to overlook the implications for how Sol can accelerate your engineering workflows
Andrew Curran: Quote from OpenAI on the livestream.
'Already, Sol has been transforming our research program. As one example, GPT-5.6-Sol autonomously post-trained GPT-5.6-Luna.'
