CLAUDE OPUS 5.5, GPT-6 SOL, GPT-6 LUNA, AND A NEW PRICE WAR (6 MINUTE
READ) [7]

other. OpenAI's GPT-6 Sol and Luna are half the price of the
promotional pricing for GPT-5.6 equivalents. Opus 5.5 is cheaper per
token than Opus 5.0 and has the intelligence of Fable 5.1. It is very
token efficient and works across every effort level.

ALZHEIMER'S IS NO LONGER AN UNTREATABLE DISEASE, MAJOR REPORT
CONCLUDES. HERE'S WHY (7 MINUTE READ) [9]
There are currently hundreds of clinical trials worldwide
investigating possible medicines, new diagnostic options, and
lifestyle interventions to identify, treat, or delay cognitive
decline. The possibility of a cure is still far away, but it now seems
more possible than ever before. Alzheimer's disease is being
increasingly viewed as a condition for which earlier diagnosis, better understanding of disease biology, and a wider range of interventions
may collectively improve outcomes. There is now a genuine case for
optimism.

BUG BLINDNESS (35 MINUTE READ) [13]
Some bugs give normal users such a bad experience that they tell
their friends about it. Developers and advanced users can be blind to
these bugs because they're used to performing the non-intuitive
workarounds required to get around them. Humans have a high ability to
ignore the negatives in things they like. Being open to criticism can
help developers notice more flaws in their work.

DEFENSIVE DRIVING FOR YOUR CAREER (10 MINUTE READ) [14]
To have a positive career, you need to be appropriately recognized
and rewarded for your work. Take public credit in a way that isn't
obnoxious or wasteful. Don't let anyone lie about you, and beware of
people who think you got lucky. Maintain leverage at all times -
leverage mainly comes from your ability to walk a valuable asset (your
labor) out the door.
THE PLUNGING PRICE OF THOUGHT (54 MINUTE READ) [15]
The cost of a given level of AI performance has fallen an average of
around 47% per quarter over the past three years. AI spending can
still remain high despite falling prices. Lower prices allow for more
agents to be run. Also, AI's ability keeps rising, and the price of
harder tasks is higher.
