I'm sure you're aware but it's worth pointing out that you will lose all your cache hit discounts with some providers. The next turn will incur the cost of the whole trajectory billed at fresh input token rates.
As an aside, 95 pages into the system card for Claude Opus 4.6, Anthropic acknowledges that they have disabled prompt prefill.
It's mostly the US and a few other small markets that even have millimeter wave 5G NR. This is mostly due to the fact that FCC had not wound down analog broadcasts in time, and mmWave/FR2 was the only way to do 5G in the US initially, as lower C-band were not freed up until 2021. Deployments of mmWave exist solely due to the sunk cost of existing equipment and narrow use-cases like stadiums and concerts.
The article predates our current reality where C-band (3.5GHz) is available for 5G
There is an A16z company that does exactly this, called yupp.ai. They need genuine labelling/feedback in return, but you get to either spend credits on expensive APIs or cash out. Likewise, openrouter has free endpoints from some providers who will retain your sessions for training.
You could also check the world catalog to see if a library near you offers the ebook for lending. Universities typically allow the general public to walk in and look at books without registration.
The technique you mention is very outdated and not used anymore. Current thin-bezel OLED panels (even on flexible substrate OLED) use a packaging technique which can be used in the exactly same way on rigid LCD panels. Folding the substrate with driver bonded is expensive, affects yields, and doesn't even get you the thinnest bezels
There are no LCD panels in recent phones that use COG packaging (chip-on-glass) for the display driver and run into the limitation you mentioned. Almost all current LCD phones will utitlize COF (chip-on-film) where the TFT array is attached to a flex-pcb which also contains the display driver.
You can achieve bezels just as thin or thinner using this technique, and Apple has used the technique you mention only once, COF is used even on flexible OLED panels.
All you need to do is to start your search on f-droid, the app quality is much better (also consider adding the IzzyOnDroid repo if you don't care about verified reproducible builds)
