Japan is good at air conditioning because good chunks of it are at the same latitude as the Sahara Desert while receiving monsoon level rainfall.
Cooling and dehumidification are kind of important for them.
My entire AI stack is now Chinese 🇨🇳
87% cheaper. same revenue
swaps by task:
1. reasoning / backend brain
Opus 4.8 → Kimi K2.7
benchmark gap: ~8% · price: ~11x cheaper
2. code generation
GPT-5.5 → Qwen 3.7 Max
benchmark gap: ~18% · price: ~7x cheaper
3. agent loops + tool calling
Sonnet 4.7 → GLM 5.2
benchmark gap: ~3% · price: ~5x cheaper on input
4. cheap volume / bulk processing
GPT-5.5 mini → MiMo V2.5
benchmark gap: ~6% · price: ~12x cheaper
5. image generation
GPT-Image-2 → Wan 2.5
benchmark gap: ~5% · price: ~8x cheaper
6. video generation
Sora 2 → Kling 3.0
benchmark gap: roughly equal · price: ~6x cheaper
[ result after 30 days: ]
operating costs dropped 87%, output quality dropped 4% on average, revenue unchanged
the most important that these models will be not banned in a month and i can run them locally
nobody will steal my data and i can learn them as i need
full article drops tomorrow with:
> exact routing logic per task type
> the 2 cases where I still pay for American
> the migration playbook anyone can copy in a weekend
VERY IMPORTANT to get migrated now, while it's not too late
in case you’ve been living under a rock
and still haven’t tried open source models
here are the best ones to try before the US govt tries to ban them too
which one's are you using?
elon says grok v9 (1.5T) finished training and evals look good.
this is what that actually means.
the grok everyone's using right now (4.3) runs on v8-small, 0.5T params and sits at 70.8% on swe-bench.
v9 is 3x the params, cursor data baked in. so the jump he's hinting at is 70.8 up to ~88 in one shot, a frontier tier... and landing right between opus 4.8 and gpt-5.5.
~17 points in one gen, landing right between opus 4.8 and gpt-5.5.
if it's real, you start seeing people run research and coding in the same model which is wild..
BREAKING: Elon Musk confirms Grok 4.5 is now in private beta at SpaceX and Tesla.
• Early evals show performance close to, possibly exceeding Opus
• Based on xAI’s 1.5T V9 foundation model
• Trained with Cursor data added
• Grok Build harness is getting better every day
• New models trained from scratch will be released every month this year
The pace at SpaceXAI is absolutely insane.
