TANDIU AI infrastructure data missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Available tools 16

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

estimate

estimate_enterprise_ai_cost

Monthly AI cost for 10 / 100 / 1,000 / 10,000-person company samples across industries: API (per-role model choice, or the open model's official API) vs self-hosting the same open model on public cloud, private cloud or on-premises GPUs, with GPU count and cost per 1M tokens.

estimate_role_token_budget

Monthly token usage and cost for 32 common job roles at light / standard / heavy AI usage, with the best model (any country) and the best Chinese model that meet each role's capability floor.

estimate_self_hosting

VRAM, GPUs needed, single-stream and batched throughput, hardware cost and the vendor's official API price/speed for self-hosting an open-weights model. Omit model to list available models.

llm

get_llm_price_history

Pro (API key required): daily official list-price history per model since July 2026, USD and RMB per 1M tokens, with source URLs. Filter by model, vendor, country and date range.

list_llm_prices

Official API list prices (USD per 1M tokens) with Artificial Analysis, LiveBench 2.0 and Epoch AI scores for major US and Chinese LLMs. Filter and sort.

mcp

find_mcp

Official MCP servers of major US / Chinese / regional companies (payments, maps, finance data, collaboration, cloud, model platforms): transport, auth barrier, account requirements, pricing model, free quota (doc wording), daily cross-border reachability measured by TANDIU (China<->US handshake; evidence=probe), listing on MCP Registry / Claude directory. Facts only, no scores.

get_mcp_changes

Append-only change events of tracked official MCP servers (terms/pricing pages, cross-border reachability, tools, status, directory listing) for the last N days, optionally for one entry id from find_mcp.

price

get_price_index

Chain-linked LLM price index (CN, US or all models), 30-day change, median price and series.

list_price_changes

Official list-price cuts/increases observed in daily snapshots, and models newly added to tracking.

about

about_tandiu_data

What data TANDIU publishes, refresh cadence, price basis and how to cite. Call first.

cheapest

cheapest_model_for_score

Cheapest models whose benchmark score meets a threshold (absolute or percent of the best score).

cloud

list_cloud_agents

Cloud agents (Personal Agents, Work Agents, hosting platforms) with specs and monthly prices.

funding

list_ai_funding

Funding rounds of AI companies (mainly US and China): company, business, round, amount, valuation, investors, source links. Newest first; filter by region, sector, company/investor name, date or minimum amount.

gpu

list_gpu_prices

Data-center, workstation and consumer GPUs (B300/B200/H200/H100/H20, Ascend 910B/910C, RTX PRO 6000/5500/5000, RTX 5090/5090D/4090D, L40S/L20): VRAM, bandwidth, FP16 compute, list price, China market price (SXM GPUs per 8-GPU node), cloud rental with 7-day change and daily median history (since 2026-10-18; few_samples flags thin markets), sources and dates. Rental comes from vast.ai; data-center GPUs include multi-GPU machines normalised per GPU; RTX 5090D/4090D have no rental (not listed on that market) and RTX 4090 is rental-only. Trend page: /en/gpu-rental.

overseas

list_overseas_listings

Where Chinese open models (DeepSeek, Qwen, GLM, Kimi, MiniMax, ...) are listed on platforms headquartered outside mainland China: hosting type, regions, input/output/blended USD per 1M tokens vs the official price, context, tool calling, data-policy links. Labs ranked by Hugging Face followers, models by downloads and likes.

recommend

recommend_coding_pc

Relative speed and tier (best/recommended/minimum/not_advised) of Macs, laptops and desktops for running Codex / Claude Code.

TANDIU AI infrastructure data — questions

Answers built from our own checks of this server.

What can TANDIU AI infrastructure data do?

It exposes 16 tools, read directly from the server on our last check. Among them: about_tandiu_data, cheapest_model_for_score, estimate_enterprise_ai_cost, estimate_role_token_budget, estimate_self_hosting, find_mcp and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is TANDIU AI infrastructure data mostly used for?

Its tools cluster around estimate, price and mcp. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is TANDIU AI infrastructure data working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1580 ms. The bar chart above shows every period we have measured.

How do I connect TANDIU AI infrastructure data?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does TANDIU AI infrastructure data need an API key?

No. TANDIU AI infrastructure data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TANDIU AI infrastructure data?

It answers our handshake in 1580 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
