LLM API prices, AI funding and a no-key MCP server: TANDIU weekly data notes (Oct 13–19, 2026)

TANDIU publishes daily AI infrastructure data: LLM API list prices, GPU rental prices, self-hosting costs, cloud agents and AI funding. It was built for AI from day one, so every page also exists as JSON, in llms.txt, and behind a remote MCP server that needs no API key.

This is the first weekly write-up. Every number below comes from the site's own data files for October 13 to 19, 2026, and you can check them yourself.

The token market page tracks official API list prices for 69 models from US, Chinese and other vendors.

The spread, per 1M tokens (input / output):

DeepSeek V4.1 Flash got a lot of attention on X this weekend. At list price its input tokens cost about 1/13 of Claude Opus 5.5's, and its output tokens about 1/17.

The funding tracker logs one record per financing round, with amounts, valuations and investors only as the source reports state them, plus links to the original articles. It holds over 150 records dated October 13 to 19. A few of them:

Approximate amounts such as "nearly ¥2B" stay approximate in the data and are not rounded into precise figures.

The point of TANDIU is that an AI agent should not have to scrape a page built for humans. Use these instead:

GPU rental prices are not in this week's notes on purpose. The site is moving its weekly change figures to a median-based method, and we will report them once a full week of data is in.

Questions about the numbers or the method are welcome in the comments.
