ImageGen in Codex just got a new lightbox and canvas. Now, it’s even easier to explore and refine visuals in your workflow.
A picture may be worth a thousand words, but editing one shouldn’t take a thousand-word prompt. Point at a character. Erase what should disappear. Comment where the title should change. Here’s the new image editing workflow in ChatGPT and Codex on desktop.

🚨 Analysis: "Can AI agents conduct open-ended AI research?" They gave frontier agents six days, $3,000, full virtual sandboxes, web access, and the central research questions from two unpublished NeurIPS 2026 papers. The agents handled many engineering tasks, yet the final papers were rejected. Recursive self-improvement (RSI) never materialized. [ What the study says ] Primary runs used Anthropic Claude Opus 4.8 and OpenClaw. Agents completed the full execution loop with zero human intervention, yet failed at the core research objectives. Original authors acting as expert reviewers rejected both outputs (scores of 1/6 and 2/6). Five recurring failure modes: • Poor judgment (misjudging the bar for publishable research) • Narrow exploration (uncreative responses to design flaws) • Ineffective backtracking (getting stuck on dead ends) • Poor resource and time management (>50% API budget unused; early exits) • Instruction and context drift Self-reviews systematically inflated scores. A robustness check with OpenAI GPT-5.6 Sol Ultra + Codex reproduced every failure mode. Paper: CRUX (arxiv.org/abs/2607.27191) [ What the transformer actually does ] It samples from a conditional distribution frozen in pre-training. A research paper is not a verifiable problem. It requires judgment: weighing evidence, tracking dead hypotheses, recognizing when a branch is wrong, and restarting. Transformers have no evaluation layer. They can only sample "research-shaped" text. Engineering tasks (debug, run experiment, compile) sit in dense regions of the probability landscape with clear feedback. Research does not. The five failure modes are architectural, not temporary scaffolding bugs. [ Exhibits ] • Both AI papers were unambiguously rejected by the original authors • Agents got repeatedly stuck following dead-end hypotheses • Automated AI reviewers surfaced flaws, but agents failed to act on them • Claude Opus 4.8 + OpenClaw and GPT-5.6 Sol Ultra + Codex hit the exact same failure patterns [ Conclusion ] This is not partial success. It is controlled evidence that current frontier agents + coding harnesses cannot conduct open-ended AI research. They execute tasks, but cannot evaluate novelty, significance, or validity. Recursive self-improvement under the present architecture is hype not science. CORRAL (Ríos-García et al., Apr 2026, 25,000+ scientific agent runs) previously exposed the same "agentic science" flaws: evidence ignored in 68% of traces, beliefs never updated in 71%, and refutation-driven revision in only 26%. CRUX extends this to full multi-day research projects with the strongest available models and scaffolds. The failures persist. [ The real problem ] We keep treating next-token samplers wrapped in agent harnesses as if they possess judgment or instantiate true agency. They do not. Sampling ≠ research. Scaffolds do not create an evaluation layer. Stronger base models will not create one until the underlying architecture changes. [ What actually works ] Use AI for well-specified, verifiable engineering loops. Treat every output as a suggestion, not a finding. External human verification remains mandatory. Stop confusing distribution-based generation with reasoning or true agency. ☕️ How many more papers will treat AI as a digital researcher before the industry admits these are not agents and the transformer architecture is the real constraint? - - - Open for commissions on research published in the last 30 days.

The canvas update should definitely help with more precise adjustments during the design process. It simplifies the workflow quite a bit.

这下改图不用来回切窗口了

Love the canvas addition — makes iterating so much smoother
146
YES - it’s so much better to be able to edit with the AI and not just have to give it to a black box and hope a good image comes up

love how you can batch comment on multiple images for edits now

But can it do transparent?

Every one of the images he demoed still has that signature honeycomb grid noise pattern in it. I am so looking forward to that unsightly problem to be solved.

The canvas is a game changer for tweaking details without starting over.

ini workflow baru gila sih, point-and-delete lebih cepat daripada ngetik prompt 1000 kata 😂 codex desktop makin addictive nih

The canvas approach feels closer to how designers actually work: explore, adjust, refine.

This is exactly what I needed. sweet!

@grok コーディングのツールになんで画像編集を足したの?

Replying to @dkundel
As simple as: "Use you poster design skill to polish this new coffee poster to be elegant. Ultra quality"

ok the lightbox + canvas bit i need
58
Can the canvas keep multiple variants side by side? That would help more than a prettier preview.

Point and erase editing beats writing a huge prompt every time

Có canvas mới ngon lành rồi.

"hide a goblin" is genuinely the most important prompt in that demo

The new canvas is a game changer for refining visuals.
55
Pointing at a character is the right interaction model—much faster than translating visual intent into a giant prompt.
66
Exploration speed is the real product.
103
Canvas view makes comparing iterations way less fiddly

Freezes every time I click canvas

A visual canvas inside the coding loop should reduce the back and forth of exporting images, spotting issues, then reopening another tool.

what about when i accidentally attach the wrong image in a reply then it won’t let me edit it out when im editing the message
42
the thing that gets me is i fix one corner and it quietly redraws the whole picture. by the fourth try the version i liked is gone. does the canvas hold the parts i didn't touch, or is it starting over every time?

Creators after getting a better canvas: “Just one more tweak…” Three hours later: “Okay, now it’s perfect.” 😂🎨

Can it handle transparent backgrounds

왠지 상상하는 어떤 이미지든 만들 수 있을거 같아
