DATAKU

What is DATAKU?
DATAKU is a data science site that tracks AI benchmarks, API pricing, and model releases, then packages the numbers into free calculators and downloadable datasets. The homepage archives articles on inference costs, funding rounds, and head-to-head model comparisons, while the Tools section hosts eight utilities such as an LLM cost calculator, benchmark decoder, and model graveyard.
Most AI news sites summarize press releases. DATAKU cross-references provider docs, leaderboard scores, and its own pricing tables, which is why the downloadable datasets page lists 48-row pricing histories and 62-row benchmark score tables under CC BY 4.0 licenses.
Data analysts, ML engineers, and buyers use DATAKU when they need cost-per-token math, benchmark context, or CSV exports instead of marketing claims. The About page describes the project as benchmark and pricing tracking run by a former Tokyo data analyst.
Avian

What is Avian?
Avian sells access to open weight frontier models through an OpenAI compatible API, billed by the token. Point an OpenAI SDK client at the https://api.avian.io/v1 base URL and name a model like DeepSeek-V3.2, and the rest of the code stays as it was. Everything runs on NVIDIA B200 GPUs with speculative decoding, and Avian measures 489 tokens per second on DeepSeek V3.2.
The argument against OpenAI here is arithmetic rather than features. A million output tokens on DeepSeek V3.2 costs $0.33, against the $10.00 Avian quotes for GPT-4o, with no rate limits, no monthly minimum, and prepaid credits that never expire. What you give up is model choice, since the catalog is entirely open weight families, DeepSeek, Kimi, GLM, and MiniMax, with no GPT, Claude, or Gemini anywhere.
Developers wiring up coding agents get the clearest win, because Cursor, Claude Code, Cline, Windsurf, and Kilo Code all accept a custom OpenAI base URL. Teams with data handling rules will care that prompts and completions are processed in memory and never written to persistent storage, with only timestamps, model name, and token counts kept for billing.
One claim deserves a closer read. The homepage advertises SOC/2 approved infrastructure while the security page says Avian is still in the process of obtaining SOC 2 Type II, so that badge is work in progress rather than a finished audit.
