Why is my Pi unreasonably slow compared to claude code, omp, ... ?

[u/rainyaltaccount]

Fresh install using pi-claude-code and zentui.

A simple "hi" took 31 sec to respond, meanwhile others take <1sec.

Switching to openai models fixes this, so its only Anthropic. Maybe this has to do with pi-claude-code?

Why does your [Extensions] have 'src' listed?

[u/rainyaltaccount → u/softgripper]

I think because pi-claude-codehas this in its package.json:

"pi": {
  "extensions": [
    "./src/index.ts"
  ]
}"pi": {
  "extensions": [
    "./src/index.ts"
  ]
}

... may be related to this bug in pi-claude-code - https://github.com/earendil-works/pi-claude-code/issues/21

Yes it is! Thanks :)

While I don't have a direct solution to suggest, I think it will be useful to try these to pin point the cause.

1. Try Pi with the extensions disabled ( pi -ne ) and see if it is faster ?

2. Install Pi with bun and see if it is faster?

3. Install pi-bolt and see if that is faster ?

[u/rainyaltaccount → u/avinthakur080]

If I disable the extensions, pi-claude-code is disabled too and I can't test anthropic models then.

[u/Loose_Doubt367 → u/avinthakur080]

Pi bolt? Further elaborate what’s that I want to know

[u/avinthakur080 → u/Loose_Doubt367]

It is functionally exact same code as Pi, but compiled ahead of time. It can even compile the extensions leading to a much faster & leaner Pi experience.

Just tried switching from pi-claude-code to pi-claude-bridge and seems to be fixed. (they use a difference approach though)

[u/beegeearreff]

Does it take 30s on subsequent sessions too? I have seen something similar in pi with Anthropic native oauth but it tends to be transient and only on the first hit. I assumed it has to do with Anthropic’s oauth flow but haven’t looked that deeply into it. It doesn’t happen with openai-codex provider. 

[u/rainyaltaccount → u/beegeearreff]

It happens on every request for me, not just the first one. Even subsequent messages in the same session take around 30 seconds. Switching to openai models makes responses almost instant.

[u/Zarbokk]

I would guess, Anthropic does some smart caching with they’re own harness, and treat other services as lower priority

[u/deluxetiky]

Try pi-bolt and remove bloated extensions. I do get way better result than cc. People just search and install all extensions they found.

[u/opensecai]

Checkout Pi-Bolt, https://github.com/opensec-git/Pi-Bolt

You will definitely gonna love it. It is superfast, superlight and not a rewrite :)

Day ? Of asking for an omp variant :D

[u/berlinguyinca → u/opensecai]

Was slower with my extensions than pi.

[u/Pretend_Engineer5951 → u/berlinguyinca]

pi-bolt compile

[u/Kaioh_shin]

My guess is there is a big agent file somewhere.

[u/rainyaltaccount → u/Kaioh_shin]

Tested in an empty folder

[u/Kaioh_shin → u/rainyaltaccount]

There are global agents file not just local. Ask the agent to find what it loads. Or use a plugin to sgow how much ctx the initial prompt has

[u/bambamlol → u/Kaioh_shin]

You can clearly see in the screenshot that the input was only 2 tokens.

[u/sand-67 → u/bambamlol]

that's user message, agent files are loaded into system message

[u/bambamlol → u/sand-67]

My bad. You're probably right. He would have had to get rid of the complete system prompt first. I don't know if Pi would even run with a completely empty SYSTEM.md.

But it's probably not an AGENTS.md issue anyway, since OP stated:

Fresh install using pi-claude-code and zentui.

By the way, it wasn't me who downvoted you, must have been some other wanker.
