Anthropic asked 7 researchers to opine on the productivity boost they get from Claude Sonnet 4.5.
Results:
one "qualitative answer"
+15%
+20%
+20%
+30%
+40%
+100%; respondent indicated that his workflow is "now mainly focused on managing multiple agents"…
Prior to the release of Claude Sonnet 4.5, we conducted a white-box audit of the model, applying interpretability techniques to “read the model’s mind” in order to validate its reliability and alignment. This was the first such audit on a frontier LLM, to our knowledge. (1/15)
Introducing Claude Sonnet 4.5—the best coding model in the world.
It's the strongest model for building complex agents. It's the best model at using computers. And it shows substantial gains on tests of reasoning and math.
I had some early access to Sonnet 4.5. It is a really good model. I saw especially big jumps in doing finance and statistics, which tend to get overlooked in the focus on coding.

More and more studies are comparing AI to the brain - from memory and reading to vision and sensorimotor reactions.
And the findings often converge:
- LLMs replicate the «cognitive sins» of memory - false memories, list-length effects, fan-effect
- During reading, large models’…

For econ theorists, this (computer scientist Scott Aaronson) is 100% possible today. I actually have the APIs of even better models "talk to each other" while I work; GPT5-Thinking isn't even frontier! @joshgans & I will post slides from an internal talk later this week on this.
Just had an interesting experience with ChatGPT Pulse
Last night I asked ChatGPT a question and it gave me an answer that was just so-so
This morning the first card in Pulse was a 3x better answer to the same question
I’d be really curious how this works under the hood

this is beyond mindblowing for me.
somebody built a 5 million param language model inside minecraft, trained it, equipped it with basic conversational ability.
probably the best thing i have seen entire month.
