According to Reuters, citing the British maritime security group Ambrey, the Palau-flagged oil tanker that suffered an explosion this morning causing an engine room fire off the coast of Oman, was likely the result of a U.S. missile strike as part of continued blockade operations against Iran.
Spent 3 inspiring afternoons as a food bank volunteer packing meals for local seniors. Seeing their bright smiles when picking up the parcels made every minute worth it. Small acts, big impact!,
Adjust your sleep schedule now—sleeping before 11 PM u0026 waking at 7 AM boosts energy, focus, and mood daily! Give it a try for 1 week and feel the difference.,
A stranger noticed my flat tire on my way to work u0026 pulled over to help fix it—no payment, just said "pass it on". Restored my faith in small kindnesses today.
This weekend, I volunteered at the community food drive—packed 200 care kits for local families in need. Nothing beats the warmth of helping neighbors!
🚨TRUMP JUST DID IT ON SAVE AMERICA ACT!
He added the SAVE AMERICA Act to the Pentagon bill which only needs a simple majority 50 votes + JD Vance to pass!🔥
Trump is demanding GOP pass it immediately.
No more games!

LANCE MARTIN FROM ANTHROPIC SHOWED HOW TO DESIGN LOOPS WITH CLAUDE FABLE 5
Fable 5 is built differently from earlier models.
The old approach was prompt engineering: steer the model
with detailed instructions until it produces what you want.
Fable 5 rewards a different approach.
Design a loop with feedback, let the model self-correct,
and step back. Lance Martin from Anthropic ran experiments
that show exactly how much this matters.
—
TIP 1: SELF-CORRECTION LOOPS
The recipe: give the model a goal or rubric,
let it run, collect feedback, self-correct, repeat
until the goal is satisfied.
Lance tested this on Parameter Golf, an open-source
ML challenge: train the best model that fits in 16MB
in under 10 minutes on 8xH100s. The agent edits training
code, launches runs, reads the score, decides what to try next.
Fable 5 vs Opus 4.7 on the same challenge, 8 hours each:
Fable 5 improved the training pipeline ~6x more than Opus 4.7.
The difference in behavior is the interesting part.
Fable 5 bet on large structural changes (architecture edits)
and pushed through a quantization regression to reach
its biggest win. Opus 4.7 found a small win early and
repeated the same template: adjust a constant, measure,
keep if positive.
The takeaway: Fable 5 explores. It takes bigger swings
and recovers from setbacks instead of playing safe.

THE VERIFIER INSIGHT
One subtle point that changes results:
who does the judging matters.
Models struggle with self-critique on their own outputs.
A verifier sub-agent outperforms self-critique with Fable 5
because grading happens in an independent context window.
The agent doing the work and the agent grading the work
should not share context. Separate the roles.
—
TIP 2: MEMORY AS AN OUTER LOOP
Memory is a loop that spans across sessions.
The model writes to memory during one session,
retrieves it in future sessions.
Lance tested this on Continual Learning Bench 1.0:
an agent answers sequential SQL questions across separate
sessions, with shared memory between them.
The progression that effective memory requires:
fail → investigate → verify → distill → consult.
Where each model stops:
Sonnet 4.6 exits at step 1.
Its memory is a list of failure notes and guesses.
It rarely consults prior notes.
Opus 4.7 exits around step 3.
It creates a schema reference with uncertainty flagged,
but verification coverage is low (median run ~17%).
Fable 5 completes the progression.
In its strongest runs, verification coverage hit 73%
(22 of 30 questions). It distills learnings into general
rules that help future tasks.
The takeaway: Fable 5 doesn't just store failures.
It investigates them, verifies the fix, turns it into
a rule, and consults that rule instead of re-deriving it.
—
THE CORE LESSON
Rather than prompting and steering Fable 5 directly,
design loops that let it self-correct against environment
feedback and manage its own context through memory.
Two primitives to start:
→ a goal or rubric for self-correction
→ a shared memory store for cross-session learning
And one rule: use a separate verifier.
Don't let the model grade its own work in the same context.
Test it yourself on a hard task.
The longer and more complex the task,
the bigger Fable 5's lead.
