Ephemeris — the daily

Friday 17 July 2026

An open three-trillion-parameter model you can download, a Victorian wildlife library brought back plate by plate, and an agent that reads a page's structure instead of a screenshot of it.

The open frontier hits three trillion.

Moonshot AI shipped Kimi K3, a mixture-of-experts model with 2.8 trillion total parameters, a one-million-token context, and native vision. It activates 16 of 896 experts per token, adds Kimi Delta Attention to hold long context cheaply, and lands as an open-weight release — full weights arrive 27 July, and the API already runs at $0.30 per million cache-hit tokens.

A Victorian wildlife library, restored plate by plate.

Nicholas Rougeux spent nearly a year rebuilding William Jardine's Naturalist's Library (1833–1843). Each of its hand-coloured plates was masked and colour-corrected in Photoshop — generative fill reassembled torn engravings — and 2.35 million OCR'd words were cleaned by hand. The result is a free web edition, a seven-pound printed book, and 27 posters.

The Naturalist's Library · W. Jardine · Edinburgh, 1833–1843
  • 40 volumes
  • 1,347 plates
  • 2.35M words
  • 6,500+ links
  • 4 divisions

Agents · Observability

The page describes itself to the agent.

Sentry rebuilt how its Seer agent perceives a screen. Instead of dumping an ASCII grid of the whole page, components self-register semantic context — titles, modes, filters, values — into a registry the agent queries on demand. On the most-visited issue pages, that context fell from ~2,100 tokens to ~300, with tool-call and satisfaction rates holding steady across 14,000+ eval runs.

That's Friday.

Three picks: an open frontier model you can run, a 190-year-old library brought back by hand, and an agent that trimmed its own context by 85%.
