Shut Work 4.8
Anthropic | Might 28, 2026
What it does: Changing Opus 4.7 beginning at the moment (on the similar value), Opus 4.8 gives sooner pondering modes for one-third the price of the sooner model, in line with Anthropic. Like most of Anthropic’s fashions, 4.8 prioritizes coding talents, scoring increased than 4.7 on two coding benchmarks however not absolutely besting OpenAI’s GPT 5.5. It additionally “reaches new highs on our measures of prosocial traits like supporting consumer autonomy and performing within the consumer’s greatest curiosity,” the corporate famous within the launch, although definitions for what which means stay murky.
Additionally: Anthropic launches Opus 4.8, with honesty as its killer feature
Why it issues: Anthropic has all the time prioritized mannequin security and interpretability, however seems to be additional emphasizing that commonplace with this launch. The corporate mentioned Opus 4.7 had a 92% honesty price, along with being much less sycophantic and hallucination-prone general. The truth that it claims 4.8 reveals “considerably” decrease charges of misalignment than 4.7 signifies an more and more excessive commonplace for mannequin security, particularly as a result of Anthropic in contrast 4.8’s alignment to that of Mythos Preview.
GPT-5.5 Instantaneous
OpenAI | Might 5, 2026
What it does: OpenAI mentioned in its announcement that the lighter model of OpenAI’s just-released GPT-5.5 is much less verbose than its predecessor, GPT-5.3 Instantaneous. It additionally touted fewer hallucinations and improved factuality, saying “GPT‑5.5 Instantaneous produced 52.5% fewer hallucinated claims than GPT‑5.3 Instantaneous on high-stakes prompts masking areas like medication, regulation, and finance.”
Additionally: Anthropic’s Mythos is evolving faster than expected, reports AI safety agency
Why it issues: GPT-5.5 Instantaneous replaces GPT-5.3 because the default mannequin in ChatGPT. Once more, whereas the expectation is that every new AI mannequin will get extra environment friendly, simpler to make use of, Â and makes up much less stuff , a major enchancment in hallucinations for a mannequin most individuals use for quick queries may imply much less misinformation spreading among the many lots. That is particularly crucial given how many individuals are utilizing ChatGPT for on a regular basis well being questions, for instance.

Nemotron 3 Nano Omni
Nvidia | April 28, 2026
What it does: The newest in Nvidia’s open Nemotron household, this mannequin offers brokers with multimodal enter. Meaning they will “understand and purpose throughout visible, audio, and textual inputs inside a single shared notion‑to‑motion loop,” according to Nvidiathereby unifying a number of capabilities right into a single system.
Additionally: AI is an arms race, and the US wants $9 billion in Nvidia superchips to keep up
Why it issues: Usually, techniques of brokers want to make use of separate fashions for speech, imaginative and prescient, and textual content, that means they bounce throughout paperwork, video, and audio to finish multi-step duties. That slows down workflows, undermines the context brokers collect, and racks up inference prices. Nvidia’s method, if it really works, would streamline this course of and scale back token use, saving you cash. Try it on Hugging Face.
GPT-5.5
OpenAI | April 23, 2026
Professional Rating: 93/100
What it does: ZDNET tester-in-residence David Gewirtz technically gave GPT-5.5 an A- rating, however mentioned it “might be reductively described as higher and sooner than GPT-5.4,” which is hopefully the bare-minimum expectation for a brand new mannequin. Particularly, although, the mannequin received higher at agentic coding, clearly figuring out ideas, scientific analysis, and factual accuracy.
Additionally: I put GPT-5.5 through a 10-round test: It scored 93/100, losing points only for exuberance
Why it issues: Whereas the mannequin itself might not be leaps and bounds forward of its speedy predecessor, the short turnaround from 5.4 to five.4 — lower than two months — signifies how quickly agentic coding is accelerating OpenAI’s mannequin launch cycle. As David Gewirtz breaks downthe corporate, very similar to different frontier labs utilizing AI to construct AI, is delivery updates at an exponentially rising price.
ChatGPT Photographs 2
OpenAI | April 23, 2026
What it does: Quickly after sunsetting Soraits generative video mannequin and social platform, OpenAI considerably confusingly introduced Images 2. ZDNET mannequin tester David Gewirtz got an early look at Images 2 earlier than its launch and was impressed. Whereas he did not give this mannequin a proper Professional Rating, he mentioned it is enjoyable, an enormous leap, and actually useful for work.
Why it issues: OpenAI gave the impression to be getting out of the extra consumer-minded AI product sport when it discontinued Sora, having been crushed by Anthropic at securing profitable enterprise contracts. That OpenAI nonetheless got here out with Photographs 2 inside that redirection narrative signifies that it sees picture mills as related sufficient to enterprise AI — particularly on the heels of Anthropic’s Claude Design.
Shut Work 4.7
Anthropic | April 16, 2026
What it does: Arriving relatively quickly after Opus 4.6, this mannequin boasts new highs in honesty, diminished sycophancy and hallucinations. It additionally seems to have a knack for cybersecurity, because it backs the brand new Claude Securitylaunched shortly after the mannequin itself — however no, it isn’t Mythos, as many suspected.
Additionally: Anthropic’s new Claude Security tool scans your codebase for flaws – and helps you decide what to fix first
Why it issues: Hallucinations and honesty are among the many most tough, hard-to-solve points plaguing even the perfect fashions. For Anthropic to assert such vital positive aspects in these areas is not any small feat for an AI lab that takes security severely.
Claude Mythos (Preview)
Anthropic | April 7, 2026
What it does: It is a robust one as a result of Mythos is not really out there to the general public. Anthropic created fairly a media storm when it positioned the brand new general-purpose mannequin as too highly effective to launch as typical. Whereas the mannequin is outwardly a step change from earlier Anthropic fashions, the corporate was particularly alarmed due to the safety risk it posed, stating that “it’s strikingly succesful at laptop safety duties.”
In response to that, Anthropic spearheaded Project Glasswinga collaborative effort with a number of rival AI labs, together with Google, Nvidia, and Microsoft, in addition to safety authorities like Palo Alto Networks, “to assist safe the world’s most crucial software program, and to organize the business for the practices all of us might want to undertake to maintain forward of cyberattackers.”
Additionally: Apple, Google, and Microsoft join Anthropic’s Project Glasswing to defend world’s most critical software
Why it issues: If we’re to consider Anthropic’s steerage that Mythos poses a major risk to the world’s software program — a lot in order that solely a choose few companions can entry it — cybersecurity apparatuses as they stand might not be ready to satisfy the quickly evolving frontier of mannequin capabilities. Mythos might not be the one mannequin of its caliber, however merely the primary of many to return as soon as different labs obtain related breakthroughs.
For now, just some weeks into its launch, Mythos is helping catch software bugs in droves.
GPT-5.4
OpenAI | March 5, 2026

In response to the corporate’s personal testing (which ought to all the time be taken with a grain of salt till verified by a 3rd celebration), GPT-5.4 matches or outperforms human professionals 83% of the time.
Why it issues: As AI corporations focus extra on gaining enterprise belief (and contracts) whereas lauding what agentic AI can do, they want fashions that may deal with complicated work-related duties with minimal danger, delay, or prohibitively excessive prices. Any mannequin development that reveals prowess in skilled workflows has a greater likelihood of being taken severely by corporations struggling to undertake AI, although nothing ensures seamless integration.
Additionally: OpenAI’s new GPT-5.4 clobbers humans on pro-level work in tests – by 83%
Shut Work 4.6
Anthropic | Feb. 5, 2026
What it does: This mannequin shortly redefined the usual for autonomous agentic work, particularly for coding. That is no shock given Anthropic’s authority in constructing fashions particularly adept at programming duties. Opus 4.6 additionally demonstrated enchancment in complicated, longer-running duties general.
Why it issues: Opus 4.6’s potential to deal with duties higher by itself means you possibly can reliably offload extra of your workflow to it — one thing agentic choices normally wrestle with.
Additionally: Anthropic says its new Claude Opus 4.6 can nail your work deliverables on the first try
GPT-5.3-Codex
OpenAI | Feb. 5, 2026
What it does: This new coding mannequin — which OpenAI mentioned helped build and debug itself — might be interrupted and redirected mid-task, which, if true, is a big boon for builders utilizing it on complicated or shifting tasks with tons of trial-and-error. GPT-5.3-Codex additionally boasts run occasions of over a day and a greater grasp on consumer intent.
Additionally: OpenAI’s new Spark model codes 15x faster than GPT-5.3-Codex – but there’s a catch
Why it issues: OpenAI is making an attempt to catch as much as Anthropic’s lead in agentic coding (and, coincidentally or not, launched 5.3 Codex on the identical day as Anthropic launched Opus 4.6). Whereas ZDNET consultants typically desire Claude Code to different instruments for vibe coding, OpenAI’s rumored shift towards enterprise shoppers and away from enjoyable client instruments may finally shut that hole.
