This has to be a monstrous money loser. If they can maintain this pricing level, and if Qwen3‑Coder is as good as people say then they will have an enormous hit on their hands. A massive money losing hit, but a hit. Very interesting! PS: Did they reduce the context window, it looks like it.

Honest ? What are you thinking in terms of cost structure that makes you sure it is a money loser? Can you break down your assumptions.

Yes, but the new "thing" now is "agentic" where the driver is "tool use". So at every point where the LLM decides to make a tool use, there is a new request that gets sent. So a simple task where the model needs to edit one function down the tree, there might be 10 calls - 1st with the task, 2-5 for "read_file", then the model starts writing code, 6-7 trying to run the code, 8 fixing something, and so on...

Yup. If you’ve ever watched a 60+ minute agent loop spawning sub agents, your “one message” prompt leaves you several hundred messages in the hole.

> running at speeds of up to 2,000 tokens per second, with a 131k-token context window, no proprietary IDE lock-in, and no weekly limits! I was excited, then I read this: > Send up to 1,000 messages per day—enough for 3–4 hours of uninterrupted vibe coding. I don't mind paying for services I use. But it's hard to take this seriously when the first paragraph claim is contradicting the fine prints.

1,000 messages per day should be plenty as a daily development driver. I use claude code sonnet 4 exclusively and I do not send more than 1,000 messages per day. However, that is my current understanding. I am certainly not pressing enter 1,000 times! Maybe there are more messages being sent under the hood that I do not realize?

Your “one enter” press might generate dozens or even hundreds of messages in an agent. Every file read, re-read, read a bit more, edit, whoops re-edit, ls, grep, etc etc counts as a message.

Contradictions do not exist. Whenever you think that you are facing a contradiction, check your premises. You will find that one of them is wrong.

Neither do perfectly efficient, perfectly rational markets.

A perfectly efficient market would be a bad premise, sure.

Tried this out with Cline using my own API key (Cerebras is also available as a provider for Qwen3 Coder via via openrouter here: https://openrouter.ai/qwen/qwen3-coder ) and realized that without caching, this becomes very expensive very quickly. Specifically, after each new tool call, you're sending the entire previous message history as input tokens - which are priced at $2/1M via the API just like output tokens.…

No it’s by token. The FAQ says this:

> Actual number of messages per day depends on token usage per request. Estimates based on average requests of ~8k tokens each for a median user.

Some users who signed up for pro ($50 p.m.) are reporting further limitations than those advertised. >While they advertise a 1,000-request limit, the actual daily constraint is a 7.5 million-token limit. [1] Assumes an average of 7.5k/request whereas in their marketing videos they show API requests ballooning by ~24k per request. Still lower than the API price.

Bait and switched their FAQ after the fact too. Come on Cerebras, it’s only VC money you’re burning here in the first place, let’s see some commitment to winning market share. :money: :fire:

2k tokens/second is insane. While I'm very much against vibe coding, such performance essentially means you can get near-github copilot level speed with drastically better quality. For in-editor use that's game changing.

At full pace that means 62 mins until you hit the daily cap.

I'm so excited to see a real competitor to Claude Code! Gemini CLI, while decent, does not have a $200/month pricing model and they charge per API access - Codex is the same. I'm trying to get into the https://cloud.cerebras.ai/ to try the $50/month plan but I can't even get in.

This doesn’t feel like a competitor. Amp does tho.

I don't hear about Amp often. Have you tried it? How does it compare to Claude Code?
