I am a futurist & biohacker, but since 2019 have been working to help counteract climate change by developing large-scale carbon removal projects and companies.

Previously was running Metalplant, where we use hyperaccumulator plants to mine soil for nickel, while removing carbon dioxide through enhanced rock weathering.

Enhanced weathering works by crushing magnesium-silicate minerals and spreading them into fields to generate alkalinity that forces CO2 to become stored as bicarbonate for 10,000+ years. Olivine is one of the most efficient minerals at this process, but contains trace nickel ~0.3%.

Nickel hyperaccumulator plants grow natively in nickel-bearing soils and draw nickel up from the soil and store it in their biomass as a natural defense against predators. The plants are harvested and processed to pure nickel products. With optimized plants, hundreds of kilograms of nickel can be recovered per hectare per year.

Normally phytomining is as phytoremediation and the soil nickel level depletes, but by utilizing olivine weathering on these soils already containing nickel, we can resupply the nickel as the olivine weathers, stoichemetrically removing gross 300 tonnes of carbon for every tonne of nickel we replenish into the field.

The company was originally developed as a way to demonstrate how to create an economically viable carbon removal technology that creates valuable and important co-products that can drive the upscaling of the process.

In 2017, I started Climigitation a non-profit think tank dedicated to promoting technologies and techniques to mitigate climate change and remove atmospheric carbon dioxide. Started as a non-profit, it was known as Project Vesta and the idea was to use tropical beaches to speed up Earth's natural long-term carbon-silicate cycle. In early 2021, I left Project Vesta after that, it was split into a non-profit and a for-profit PBC. Vesta has successfully deployed olivine onto beaches in Southhampton New York, and Duck, North Carolina and now focuses on beach nourishment.

In the biohacking space, I was a "nootropics historian" and started and ran the nootropics company, Nootroo. I helped drive the adoption and acceptance of nootropics and in some ways biohacking in general. You can read a profile of me that is a snapshot from that time of my life in The Atlantic - https://www.theatlantic.com/magazine/archive/2016/10/the-brain-bro/497546/ And this is one of the last interviews I did on the topic: https://www.youtube.com/watch?v=xwYfsknlWHI You can also find interviews from that time in GQ, Men's Health, ABC Nightline News, NPR, The Guardian, among others. You can see the most accurate definition of nootropics at https://Nootroo.com

If you are a company and can't figure out how to improve your bottom line through increased per person productvity, sales, product development, even just responses to customers etc, then that seems kind of like a "you" problem and not problem of the AI models...

I think you can make it work without leaving Gists by using a Cloudflare Worker as a workaround. The Worker sits in front of the renderer page and adds the og tags to the HTML before it's sent out. You'd also need to turn the SVGs in the Gist into a PNG for the og:image, and decide if you want a grid or just one image, any text formatting, and how long to cache...

I got it working in a quick local test (grid of all the reasoning efforts, cached per Gist, loads from the raw Gist URL so it doesn't hit the GitHub API rate limit).

Code + prompt + notes here: https://gist.github.com/matznerd/ece297107bd99ac028c7962c217...

Basic concept is to:

1. Put a Worker on the /markdown-svg-renderer route. Normal visitors get your page exactly as it is now.

2. When a link has ?url=<gist>, the Worker reads the Gist and adds og:title, og:description and og:image to the page's HTML. Link previewers like Slack and iMessage don't run JS, so this is the only way they see them.

3. og:image points to a second Worker URL (og.png?url=<gist>). It takes the SVGs from the Gist, puts them in a grid, and converts it to a PNG, since previewers won't show SVGs.

4. Both results get cached per Gist, so each Gist is only fetched and rendered once, even with a lot of traffic.

Things to customize:

- Title and description (mine: "gpt-6-luna SVG of a pelican riding a bicycle" / "6 runs, reasoning effort none to max")

- Grid of all runs vs just one image, plus layout, labels and font

- How long to cache (I used a day, but edited Gists keep the old preview until it expires)

Simon, love your work, one piece of minor feedback for the individual model pages is to make the font of the model name potentially bigger than (and above) the conversation id (which means nothing to the audience) "2026-09-22T18:28:00 conversation: 01m355zvyw8946qyraa8zpz6h9 id: 01m355zvyx47zxx5c6q6b3fg0m#".

I had all the tabs open individually and harder to scan which model is which... otherwise keep up the great work! I like the grid view a lot. (Also the pages have no OG images set, which impacts what the link looks like shared)...

Not OP, but you can't set a per api key limit in OpenAI Platform, you also can't really easily see spending going on per key, and its also in a far off page separate from the keys, really not easy to see what is going on with spend in real time.

Is there any way to make it so that when you plug new things in, the power doesn't renegotiate causing other things plugged in to reconnect/flicker/interrupt.

Looking for high power USB C hubs that don't do that, but seems most do as part of PD and need isolated slots that don't draw from shared potential... programmatically locking specific power to laptop hub, while others negotiate would be ideal...

have enough sessions going that you just cycled through them and by the time you get back that chat is ready to go again. Easier sometimes staying in same project, sometimes easier if you don't use worktrees to work on different projects.

Dear Notion employees, please, if you're advertise mail and calendar as features, add them into your app and do not make them open in new tabs. I want an all in one thing, why is that so hard, you already have tabs built in? Thanks!

okay but what about "c" being nearly the same as "z", neither of which look like the character and are nearly(?) identical. Is our brain supposed to just be able to figure it out?

"A large new study published in the International Journal of Hygiene and Environmental Health provides evidence that exposure to certain workplace chemicals among parents may influence the severity of autism spectrum disorder (ASD) symptoms and contribute to behavioral, cognitive, and adaptive challenges in their children. The findings suggest that occupational exposures—especially to plastics, ethylene oxide, phenols, and pharmaceutical agents—may have broader developmental effects beyond autism diagnosis alone."

"The effects of parental occupational exposures on autism spectrum disorder severity and skills in cognitive and adaptive domains in children with autism spectrum disorder" https://www.sciencedirect.com/science/article/pii/S143846392...

The person leading this study, Erin C. McCanlies, was forced out of the CDC, her division eliminated and she went into early retirement from the CDC. https://www.psypost.org/scientist-who-linked-autism-to-chemi...

"The findings suggest that workplace exposures to several specific chemical classes were associated with worse outcomes in children with ASD. One of the strongest and most consistent patterns involved plastics and polymer chemicals. Fathers’ exposure to plastics was associated with lower scores across all cognitive and adaptive skill domains, including language, motor coordination, daily living skills, and overall functioning. When both parents were exposed, the deficits appeared to compound.

“I was surprised how strongly and consistently plastics and polymers stood out as being linked with multiple developmental and behavioral outcomes including irritability, hyperactivity, and daily living,” McCanlies told PsyPost.

Exposure to ethylene oxide—commonly used in hospital sterilization—was also linked to more severe autism symptoms, lower expressive language abilities, and poorer adaptive functioning. Similarly, parental exposure to phenol (used in construction, automotive, and some consumer products) and pharmaceuticals was associated with increased ASD severity and more pronounced behavioral challenges, especially hyperactivity and stereotyped behavior.

While the results do not imply that all children exposed to these chemicals will develop more severe symptoms, the patterns suggest that early life exposure to workplace toxicants may amplify certain developmental difficulties in children who already meet criteria for ASD. The study provides one of the most detailed looks to date at how parental occupation may relate not just to diagnosis, but to variation in how autism is expressed.

“Our findings suggest that certain parental workplace exposures may be related not just to autism, but to worse symptoms and autism behaviors,” McCanlies explained."

These are 8bit versions On mac, use LM Studio to download it, just search "oss mlx", and note there is an mlx toggle box on search.

Link for the 120B version: https://huggingface.co/lmstudio-community/gpt-oss-120b-MLX-8...

Its taking 21 gb of memory on my 64 gb mbp, still tuning it and settling on context size, temp, and other settings.

My comment from yesterday:

"thanks openai for being open ;) Surprised there are no official MLX versions and only one mention of MLX in this thread. MLX basically converst the models to take advntage of mac unified memory for 2-5x increase in power, enabling macs to run what would otherwise take expensive gpus (within limits). So FYI to any one on mac, the easiest way to run these models right now is using LM Studio (https://lmstudio.ai/), its free. You just search for the model, usually 3rd party groups mlx-community or lmstudio-community have mlx versions within a day or 2 of releases. I go for the 8-bit quantizations (4-bit faster, but quality drops). You can also convert to mlx yourself...

Once you have it running on LM studio, you can chat there in their chat interface, or you can run it through api that defaults to http://127.0.0.1:1234

You can run multiple models that hot swap and load instantly and switch between them etc.

Its surpassingly easy, and fun.There are actually a lot of cool niche models comings out, like this tiny high-quality search model released today as well (and who released official mlx version) https://huggingface.co/Intelligent-Internet/II-Search-4B

Other fun ones are gemma 3n which is model multi-modal, larger one that is actually solid model but takes more memory is the new Qwen3 30b A3B (coder and instruct), Pixtral (mixtral vision with full resolution images), etc. Look forward to playing with this model and see how it compares."
