It's interesting how even 5 tok/s is still much faster than you'd typically type, but feels glacially slow for an agent. On the other hand, I've been using Mimo and Minimax a lot recently. They routinely reach 100-150 tokens per second and that feels too fast , to the point where it's hard to keep up with what it's actually doing. Great for subagents though.

isn't 5 tok/s like 100wpm? Pretty standard typing speed.

You also would need to compare token generation not with the actual output, but with the thoughts and deleted and edited parts.

The visualiser seems to be quite naive with what it defines as a token. I don't think a token is an entire word as often as the demo shows, and when it gets to the `def estimate_tokens` method, the entire `# Rough heuristic: ~1 token per 4 chars of English` comment is printed all at once as one token, which is certainly not accurate.

This is not a realistic replay of what a common LLM might actually print out - it's entirely fabricated. But for the purpose of estimating the feel of tokens per second, I suppose it's good enough.

I built something similar awhile back [1] and used OpenAI’s tokenizer playground [2] to recalculate tokens on a giant block of lorem ipsum text. I feel like this gives a much more accurate representation.

It's about 240 wpm on text.

100wpm is well above what the average person types at, which is estimated at about 40wpm.

100wpm might still bit a bit high even for your average programmer.
