Karpathy builds HackerTube in a weekend with Claude
Sick of YouTube's recommendations, he let Opus 5.5 distill 20 years of Hacker News into a watchlist.

Frustrated with YouTube's recommendations, Andrej Karpathy had Claude filter 43 million Hacker News comments spanning two decades down to 6,454 videos that keep getting recommended. The result, HackerTube, came together in roughly two hours — and he reports a significantly better viewing experience.
DeepSeek V4.1F-1017 ties GPT 5.5 on the Epoch index
A new checkpoint scores 159, level with GPT 5.5 and well past its own predecessor.

The V4.1F-1017 checkpoint scores 159 on the Epoch Capabilities Index — equal to GPT 5.5, three points above the earlier 0910 build and ten above the original V4-Pro. Observers note Astra sits another ten points away, near what would match a 5.6-class Sol.
LlamaIndex ships Extract Max Effort, a frontier document agent
Jerry Liu calls it the strongest frontier agent for pulling structured answers out of documents.
LlamaIndex has introduced Extract Max Effort, a document-extraction agent that can dynamically spend tokens on reasoning when a task demands it. The pitch is that it trades compute for accuracy on messy, real-world documents rather than stopping at a single pass. The framing is a clear signal of where the agent stack is heading: effort as a dial, not a fixed setting.
Own your intelligence. Anyone who opposes this has something to sell you — perhaps your own intelligence back to you.

Anthropic junk-rating talk, Intel's worst day, OpenAI cuts its raise
A roundup of market chatter: Anthropic's creditworthiness is being questioned, memory-chip stocks fell in a chain reaction, Intel posted its worst day in half a century, and OpenAI is said to have slashed its funding-round target toward a DeepSeek-tier figure. Taken together, the signals point to a sector suddenly repricing how much frontier compute is worth.
