TRACKED CHANGES: Harvey’s gross margin fell from about 50% to -50% by June as agent token use spiked twentyfold on rented OpenAI and Anthropic models, Bloomberg reports.

Want to go out on a limb: in 10 years people will be cranky that there aren't enough data centers in poor or minority communities
The fact that Jev’s rise was surprising to frontier labs shows that there’s no AGI (yet)

Jev is not open-source and only available via API.
Here's an open version called Nimble which performs just as well.

The funniest thing is he was pro-AI until its capabilities surpassed him

🚨🚨SCOOP: A shipment of F-35 fighter jet parts was rerouted to Hong Kong this summer — then vanished.
Congress and DOD are investigating, amid the possibility that China may now have access to the highly-classified program.

We’re partnering with Accenture on independent evaluation of frontier AI—part of our recent commitment to embed evaluators at Anthropic. Both we and Accenture expect to invest at least $1 billion to build capacity in this area over the next five years. anthropic.com/news/accenture…
Readers added context they thought people might want to know
Anthropic presents this as an "independent evaluation" but will directly fund Accenture's work and has a prior commercial partnership with the firm for deploying its models, including training ~30,000 Accenture professionals on Claude.

Race to da bottom versus jevvy’s paradox
Kev-0.5B: A tiny open source Jev-like decision model with a TypeSafe-compatible API based on Qwen2.5-0.5B that you can train and run on a MacBook Pro.
Model card and weights are available on GitHub

fact check: true
well, well, well...
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution
The question no one's asking. How is Jev going to make money?
It's worse business model than LLMs in some sense.
Do they resell your data?
so excited someone made a jev-compatible self-hostable version so quickly.
i am simply parallelized by how many ideas i have for jev...it is an ai psychosis similar to the deepseek drop.
at the same time, at least half of my ideas require the "system one" model to be private, and half of those would require it to be local

Meet Yuen Lee, an assurance manager at KPMG.
Earlier today, she was filmed calling a Jewish man a “Zionist pig” at Chelsea Piers Flatiron.
Imagine being one of her Jewish colleagues at @KPMG.
Crazy how ZDR isn’t available for Fable
Today we rolled out Astra to every engineer at Databricks (N=~3500). Some notes that may be helpful to others:
1. Astra unambiguously out performs our previous highest-end models (Opus 5, Sol 5.6) on highly complex tasks, especially those related to high level system design or long range horizontal tasks.
2. Engineers given Astra increased overall coding spend by around 60% compared to baseline.
3. It is not clear Astra meaningfully improves on medium/low complexity coding tasks compared to earlier models. We suspect those tasks are mostly saturated (i.e. perfectly executed) by existing models.
4. We learned above by piloting Astra with around 200 users to gain signal on both quality and cost. We use Unity Gateway to do cohort-based experiments for all new models.
5. We give engineers a sub-budget specific to Astra to encourage them to use Astra selectively on complex tasks while preferring lower cost models for everyday tasks. Our engineers are able to mix-and-match tools and models within their overall budget envelope (we also allow for increased budgets through various mechanisms). These budgets are defined in Unity Gateway and regularly revisited.
Note: We do not have robust comparisons of Astra-vs-Fable because we have net yet rolled out Fable widely due to data retention policies.
