Graph showing task length at 50% success rate for AI models over time, with GPT-5.2 projection. — “AI #155: Welcome to Recursive Self-Improvement” by Zvi Feb 20, 2026
Show notes

This was the week of Claude Opus 4.6, and also of ChatGPT-5.3-Codex. Both leading models got substantial upgrades, although OpenAI's is confined to Codex. Once again, the frontier of AI got more advanced, especially for agentic coding but also for everything else.

I spent the week so far covering Opus, with two posts devoted to the extensive model card, and then one giving benchmarks, reactions, capabilities and a synthesis, which functions as the central review.

We also got GLM-5, Seedance 2.0, Claude fast mode, an app for Codex and much more.

Claude fast mode means you can pay a premium to get faster replies from Opus 4.6. It's very much not cheap, but it can be worth every penny. More on that in the next agentic coding update.

One of the most frustrating things about AI is the constant goalpost moving, both in terms of capability and safety. People say ‘oh [X] would be a huge deal but is a crazy sci-fi concept’ or ‘[Y] will never happen’ or ‘surely we would not be so stupid as to [Z]’ and then [X], [Y] and [Z] all happen and everyone shrugs as if nothing happened and [...]

Figure illustrating adversarial prefixes bypassing harmful request detection in AI models. — “AI #156 Part 2: Errors in Rhetoric” by Zvi Feb 20, 2026
Show notes

Things that are being pushed into the future right now:

Gemini 3.1 Pro and Gemini DeepThink V2.

Claude Sonnet 4.6.

Grok 4.20.

Updates on Agentic Coding.

Disagreement between Anthropic and the Department of War.

We are officially a bit behind and will have to catch up next week.

Even without all that, we have a second highly full plate today.

Table of Contents

(As a reminder: bold are my top picks, italics means highly skippable)

Levels of Friction. Marginal costs of arguing are going down.

The Art Of The Jailbreak. UK AISI finds a universal method.

The Quest for Sane Regulations. Some relatively good proposals.

People Really Hate AI. Alas, it is mostly for the wrong reasons.

A Very Bad Paper. Nick Bostrom writes a highly disappointing paper.

Rhetorical Innovation. The worst possible plan is the best one on the table.

The Most Forbidden Technique. <wonka voice> No, stop, come back. </wonka>

Everyone Is Or Should Be Confused About Morality. New levels of ‘can you?’

Aligning a Smarter Than Human Intelligence is Difficult. Seeking a good basin.

maria >ω< tweets: — “AI #156 Part 1: They Do Mean The Effect On Jobs” by Zvi Feb 19, 2026
Show notes

There was way too much going on this week to not split, so here we are. This first half contains all the usual first-half items, with a focus on projections of jobs and economic impacts and also timelines to the world being transformed with the associated risks of everyone dying.

Quite a lot of Number Go Up, including Number Go Up A Lot Really Fast.

Among the thing that this does not cover, that were important this week, we have the release of Claude Sonnet 4.6 (which is a big step over 4.5 at least for coding, but is clearly still behind Opus), Gemini DeepThink V2 (so I could have time to review the safety info), release of the inevitable Grok 4.20 (it's not what you think), as well as much rhetoric on several fronts and some new papers. Coverage of Claude Code and Cowork, OpenAI's Codex and other things AI agents continues to be a distinct series, which I’ll continue when I have an open slot.

Most important was the unfortunate dispute between the Pentagon and Anthropic. The Pentagon's official position is they want sign-off from Anthropic and other AI companies on ‘all legal uses’ [...]

Gary Grumbach tweets: — “Monthly Roundup #39: February 2026” by Zvi Feb 18, 2026
Show notes

There really is a lot going on these days.

I held off posting this because I was trying to see if I could write a net helpful post about the current situation involving Anthropic and the Pentagon. Anthropic very much wants to help DoW defend our country and make us strong. It is clear there have been some large misunderstandings here about how LLMs work.

They are not ordinary tools like spreadsheets that automatically do whatever the user asks, nor would it be safe to make them so, nor do they predictably adhere to written rule sets or take instructions from their CEO in a crisis. And they are probabilistic. You do not and cannot get absolute guarantees.

The only way to know if an AI model will do what you need in a crisis is something you needed to be do regardless of potential refusals, and which is also what you must do with human soldiers, which is to run the simulations and mock battles and drills and tests that tell you if the model can do and is willing to do the job.

If there are irreconcilable differences and the military contract needs [...]

Three men sitting at bar table with dark beers and illuminated shelves behind. — “On Dwarkesh Patel’s 2026 Podcast With Elon Musk and Other Recent Elon Musk Things” by Zvi Feb 17, 2026
Show notes

Some podcasts are self-recommending on the ‘yep, I’m going to be breaking this one down’ level. This was one of those. So here we go.

As usual for podcast posts, the baseline bullet points describe key points made, and then the nested statements are my commentary. Some points are dropped.

If I am quoting directly I use quote marks, otherwise assume paraphrases.

Normally I keep everything to numbered lists, but in several cases here it was more of a ‘he didn’t just say what I think he did did he’ and I needed extensive quotes.

In addition to the podcast, there were some discussions around safety, or the lack thereof, at xAI, and Elon Musk went on what one can only describe as megatilt, including going hard after Anthropic's Amanda Askell. I will include that as a postscript.

I will not include recent developments regarding Twitter, since that didn’t come up in the interview.

I lead with a discussion of bounded distrust and how to epistemically consider Elon Musk, since that will be important throughout including in the postscript.

What are the key takeaways?

Elon Musk is more confused than [...]

Person wearing blue cardigan and glasses gesturing while speaking near microphone. — “On Dwarkesh Patel’s 2026 Podcast With Dario Amodei” by Zvi Feb 16, 2026
Show notes

Some podcasts are self-recommending on the ‘yep, I’m going to be breaking this one down’ level. This was very clearly one of those. So here we go.

As usual for podcast posts, the baseline bullet points describe key points made, and then the nested statements are my commentary. Some points are dropped.

If I am quoting directly I use quote marks, otherwise assume paraphrases.

What are the main takeaways?

Dario mostly stands by his predictions of extremely rapid advances in AI capabilities, both in coding and in general, and in expecting the ‘geniuses in a data center’ to show up within a few years, possibly even this year.

Anthropic's actions do not seem to fully reflect this optimism, but also when things are growing on a 10x per year exponential if you overextend you die, so being somewhat conservative with investment is necessary unless you are prepared to fully burn your boats.

Dario reiterated his stances on China, export controls, democracy, AI policy.

The interview downplayed catastrophic and existential risk, including relative to other risks, although it was mentioned and Dario remains concerned. There was essentially no talk about alignment [...]

Table showing destructive action avoidance scores across five GPT model versions. — “ChatGPT-5.3-Codex Is Also Good At Coding” by Zvi Feb 13, 2026
Show notes

OpenAI is back with a new Codex model, released the same day as Claude Opus 4.6.

The headline pitch is it combines the coding skills of GPT-5.2-Codex with the general knowledge and skills of other models, along with extra speed and improvements in the Codex harness, so that it can now handle your full stack agentic needs.

We also got the Codex app for Mac, which is getting positive reactions, and quickly picked up a million downloads.

CPT-5.3-Codex is only available inside Codex. It is not in the API.

As usual, Anthropic's release was understated, basically a ‘here's Opus 4.6, a 212-page system card and a lot of benchmarks, it's a good model, sir, so have fun.’ Whereas OpenAI gave us a lot less words and a lot less benchmarks, while claiming their model was definitely the best.

OpenAI: GPT-5.3-Codex is the most capable agentic coding model to date, combining the frontier coding performance of GPT-5.2-Codex with the reasoning and professional knowledge capabilities of GPT-5.2. 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 [...]

Illuminated gauge displaying numerical values from 1.0 to 5.3. — “Claude Opus 4.6 Escalates Things Quickly” by Zvi Feb 11, 2026
Show notes

Life comes at you increasingly fast. Two months after Claude Opus 4.5 we get a substantial upgrade in Claude Opus 4.6. The same day, we got GPT-5.3-Codex.

That used to be something we’d call remarkably fast. It's probably the new normal, until things get even faster than that. Welcome to recursive self-improvement.

Before those releases, I was using Claude Opus 4.5 and Claude Code for essentially everything interesting, and only using GPT-5.2 and Gemini to fill in the gaps or for narrow specific uses.

GPT-5.3-Codex is restricted to Codex, so this means that for other purposes Anthropic and Claude have only extended the lead. This is the first time in a while that a model got upgraded while it was still my clear daily driver.

Claude also pulled out several other advances to their ecosystem, including fast mode, and expanding Cowork to Windows, while OpenAI gave us an app for Codex.

For fully agentic coding, GPT-5.3-Codex and Claude Opus 4.6 both look like substantial upgrades. Both sides claim they’re better, as you would expect. If you’re serious about your coding and have hard problems, you should try out both, and see what combination works [...]

Bar graph titled — “Claude Opus 4.6: System Card Part 2: Frontier Alignment” by Zvi Feb 10, 2026
Show notes

Coverage of Claude Opus 4.6 started yesterday with the mundane alignment and model welfare sections of the model card.

Today covers the kinds of safety I think matter most: Sabotage, deception, situational awareness, outside red teaming and most importantly the frontier, catastrophic and existential risks. I think it was correct to release Opus 4.6 as an ASL-3 model, but the process Anthropic uses is breaking down, and it not on track to reliably get the right answer on Opus 5.

Tomorrow I’ll cover benchmarks, reactions and the holistic takeaways and practical implications. I’m still taking it all in, but it seems clear to me that Claude Opus 4.6 is the best model out there and should be your daily driver, with or without Claude Code, on most non-coding tasks, but it is not without its weaknesses, in particular in writing and falling into generating more ‘AI slop’ style prose than Claude Opus 4.5.

For coding tasks, I presume that Opus 4.6 with Claude Code is the play, especially with Agent Teams and fast mode available, and I’m using it myself, but Codex with GPT-5.3-Codex-Max is also a strong model and a viable alternative, and a fully [...]

“Claude Opus 4.6: System Card Part 1: Mundane Alignment and Model Welfare” by Zvi Feb 09, 2026
Show notes

Claude Opus 4.6 is here. It was built with and mostly evaluated by Claude.

Their headline pitch includes:

1M token context window (in beta) with State of the art retrieval performance.

Improved abilities on a range of everyday work tasks. Model is improved.

State of the art on some evaluations, including Terminal-Bench 2.0, HLE and a very strong lead in GDPval-AA.

Claude Code now has an experimental feature called Agent Teams.

Claude Code with Opus 4.6 has a new fast (but actually expensive) mode.

Upgrades to Claude in Excel and the release of Claude in PowerPoint.

Other notes:

Price remains $5/$25, the same as Opus 4.5, unless you go ultra fast.

There is now a configurable ‘effort’ parameter with four settings.

Refusals for harmless requests with rich context are down to 0.04%.

Data sources are ‘all of the above,’ including the web crawler (that they insist won’t cross CAPTCHAs or password protected pages) and other public data, various non-public data sources, data from customers who opt-in to that and internally generated data. They use ‘several’ data filtering methods.

Thinking mode gives better [...]
