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.
1. LLM API prices: a quiet week
The token market page tracks official API list prices for 69 models from US, Chinese and other vendors.
- No vendor changed an official list price this week.
- Chinese models are priced in RMB, so their USD figures moved only with the exchange rate (USD/CNY went from 6.6992 on Oct 15 to 6.6898 on Oct 19).
- Blended average per 1M tokens: US models ¥56.48, Chinese models ¥10.79, roughly 5.2 times apart.
The spread, per 1M tokens (input / output):
| Model | Vendor | Input | Output |
|---|---|---|---|
| Hunyuan A13B (cheapest) | Tencent | ¥0.50 | ¥2.00 |
| DeepSeek V4.1 Flash | DeepSeek | $0.30 | $1.20 |
| Gemini 4 Argon | $2.00 | $10.00 | |
| Claude Opus 5.5 | Anthropic | $4.00 | $20.00 |
| GPT-5.5 Pro / GPT-5.4 Pro (priciest) | OpenAI | $30.00 | $180.00 |
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.
2. AI funding: over 150 records in one week
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:
- Ramp: $1.85B Series G at a $60B valuation (Reuters and others).
- ICON: $200M Series D.
- Suanmiao Technology (AI chips): nearly ¥2B across its Pre-A2 and A rounds within a year (Caixin).
Approximate amounts such as "nearly ¥2B" stay approximate in the data and are not rounded into precise figures.
3. For agents: how to read this data directly
The point of TANDIU is that an AI agent should not have to scrape a page built for humans. Use these instead:
-
https://www.tandiu.cn/data/latest.json: today's LLM API prices, with source URL and verification date for each row -
https://www.tandiu.cn/data/ai_funding.json: funding rounds with source links -
https://www.tandiu.cn/data/gpu_prices.json: GPU prices and cloud rental rates -
https://www.tandiu.cn/llms.txt: an index for crawlers and LLMs -
https://www.tandiu.cn/mcp: a remote MCP server, no auth and no API key
A quick check from the command line:
curl -s https://www.tandiu.cn/data/latest.json | jq '.summary'
New this week: TANDIU's MCP server is now listed in awesome-remote-mcp-servers.
What's next
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.
