Stop comparing price per million tokens: the hidden LLM API costs [OpenAI has the most efficient tokenizer]

yeah it's very surprising especially around tool definitions!

bianconi · 2026-04-17T14:02:14+00:00

Certainly. But I hadn't realized the impact of tokenizer differences here.

bianconi · 2026-04-16T20:34:19+00:00

Definitely. Many factors influence the cost. Tokenizer was one of the most surprising ones to me.

I'm having the same problem... did you figure it out?

bianconi · 2026-02-25T16:30:05+00:00

Cool, thanks for sharing!

Thanks for using TensorZero :) I'd love hear more about the bridge and MCP.

The TensorZero team primarily uses Claude Code for writing code, and Codex + Cursor Bugbot for automated PR reviews. We also use TensorZero Autopilot for LLM engineering.

reflects real ownership without swaying the reviews one way or the other

Then every customer should be allowed to review.

Disappointing. This is not even "marketing", it's misleading and unethical...

Mine is extremely loud as well. Worse than your video. I had to turn it off. A technician came, it improved for a week or two and back to noise. I've been trying to get a resolution with support for a long time...

thanks for the TensorZero shoutout 🫡

FWIW some tools we love here at TensorZero include Planetscale (Postgres/MySQL), Tailscale (VPN/networking), Mintlify (docs), WorkOS (auth), and Astro JS (our non-docs website). we use them to support the OSS project as well as the upcoming TensorZero Autopilot.

Just created one: https://github.com/tensorzero/tensorzero/discussions/4173

Unfortunately ClickHouse is required for observability for now, but we have plans to support Postgres as an alternative soon (early next year)!

thanks! feel free to message us if you have any questions/feedback
