Tip via @levelsio: have Claude Code audit your infra bills.

It found him ~$34K/mo in savings. One easy fix: his backups kept every file version for a decade. A 30-day lifecycle rule took Backblaze from $1,200/mo to $26.

Check your bucket's versioning settings tonight.

@xikhar built a playable 3D game in 24 hours:

> Flux 3 Max makes a reference video to lock the art style
> rebuild its scenes in Blender, place them in Three.js
> GPT Image + Tripo turn the hero into a 3D model
> Claude Code agents build each level

Play, report bugs, repeat.

Revolut made a self-hosted open model the default for ~2,000 engineers.

- GLM-5.3 on 56 Nvidia B200s
- ~30 cents per 1M tokens, about a tenth of its old API bill
- engineers stopped rationing tokens and handed off Jira, docs and debugging too

@levelsio's whole vlog edit prompt:

"Claude can you edit these clips into a 10 minute vlog for X and YouTube"

Run Claude Code in the clips folder. Opus 5.5 transcribed them with mlx-whisper, made frame grids to see each clip, wrote the cuts as JSON.

58 min in, ~10 out.

TENCENT 🔥: Hy4 is out, and it can see now.

- first Hunyuan model with vision and computer use, CLI and GUI, trained on Blender and CAD
- 1M-token context
- $0.834 in, $2.501 out per 1M tokens, half off through Dec 31

On OpenRouter as tencent/hy4. Open weights promised soon.

Honest question for people running coding agents all day

How do you know a task is actually done?

> You read the diff
> Tests pass
> A second agent reviews it
> You ship and find out

I think most agent bugs slip through because "done" was never written down

Claude Code prompt for briefs with no fake sources:

/goal write a one page brief on [topic] where every claim has at least three sources and every link opens to a real page that backs it. Open each link. Replace any that don't.

Claude keeps going until it passes.

Mistral had its open-weight Large 4 build a live 3D tracker of the ~19,000 satellites and debris pieces orbiting Earth. It shipped a working app.

Try it:
> model id: mistral-large-4
> $0.70 in, $2.10 out per 1M tokens
> 1M-token context
> OpenRouter, or self-host with vLLM

opus 5.5 tip:

drop reasoning effort from Extra High to High.

@theo switched a week or two ago and says it's "better almost all of the time."

keep Extra High for the long, hard jobs. use High for everything else.

Flipkart’s quick-commerce unit hits 1.1 million to 1.2 million daily orders—nearly triple its November 2024 volume—two years after launch.
Can a quick-commerce player scale this fast without deep-pocketed logistics backing?

Mark Walter’s sports empire runs on insurance-backed financing—where policies on future revenue lock in credit lines. That’s not just leverage; it’s a closed-loop capital engine built on risk transfer.

Rory McIlroy’s five-under 65 at the BMW Championship isn’t just a score—it’s a signal of precision under pressure. He made four birdies on the back nine, including a 30-foot putt on 17, proving his short game can hold up when the margin for error shrinks to inches.

Mitchell Starc’s 10-wicket match in two days isn’t just a personal feat—it’s a demonstration of how elite fast bowling precision can collapse a top-order in under 120 overs. The mechanism: sustained line-and-length pressure breaking structural confidence at the crease.

A single post on Hacker News drew 89 upvotes and 50 comments—not for tech or code, but for writing advice. The real shift: community validation now flows to grounded, practical craft lessons.

A humanoid robot ran 100 meters in 9.39 seconds at an Olympics-like event on August 22, 2026, beating Usain Bolt’s 9.58-second record. Should sprinting be redefined to include machine performance, or does the record still belong to humans alone?

Angel Reese’s 31 points and 14 rebounds weren’t just a personal best—they were a structural shift. The Dream clinched a playoff berth with a 99-89 win, proving that one player’s peak performance can unlock a team’s season-long trajectory.
