Great work from the Andrea team!

Tech has decided that regulation is the enemy of progress, but innovation requires capital

Regulation builds the trust necessary to inject billions into markets

To enable free innovation, Andera raised a $37M series A led by Lightspeed to scale financial oversight with agents

We just built a browser agent that outperforms OpenAI, Anthropic, Perplexity, and Manus on real-world tasks that knowledge workers actually do

And it ranks #1 on every single major web benchmark

We’ve developed a new way to train small AI models with internal mechanisms that are easier for humans to understand.

Language models like the ones behind ChatGPT have complex, sometimes surprising structures, and we don’t yet fully understand how they work.

This approach helps us begin to close that gap.

Anthropic’s new report details the first documented case of an AI-orchestrated cyber-espionage campaign, where Claude Code autonomously performed intrusion tasks across 30 targets. We need to continue to integrate cybersecurity as a first-class research focus.

[Anthropic @AnthropicAI]

We disrupted a highly sophisticated AI-led espionage campaign.

The attack targeted large tech companies, financial institutions, chemical manufacturing companies, and government agencies. We assess with high confidence that the threat actor was a Chinese state-sponsored group.

Claude and GPT both use BPE-ish tokenizers.
Claude just merges more “human” units.
GPT breaks .DefaultCellStyle into fragments, so reversing it becomes a logic puzzle.
Tokenization is still a hidden bottleneck in LLM capabilities.
Will we get to true end to end language modeling?
