I missed my @openclaw bot, Chiti, yesterday. 🥺
For the past few weeks, I’ve been using my $20 ChatGPT subscription to power Chiti on GPT-5.2. Everything was smooth until I suddenly hit a strict rate limit and got blocked for 1.5 days.
The bot went silent on Telegram. It was a wake-up call without the model, an AI agent is just an appliance without electricity. Completely useless.
I tried switching to Gemini Pro as a temporary fix, but it burned through $6 within 3 hrs. I realized I needed a more sustainable architecture to manage both performance and budget.

The Solution: A Tiered Model Strategy
Instead of relying on a single model, I’ve now configured a multi-provider setup (OpenAI, Anthropic, Google, and Codex) with a tiered routing system:
1. The Daily Driver: Gemini Flash
It’s incredibly cheap and fast. Chiti uses this for 80% of our interactions - basic chat, task management, and simple pings. This keeps the baseline cost near zero.
2. The Coder: GPT-5.2 (via ChatGPT Plus)
This is now strictly reserved for building features or debugging. By isolating it, I avoid wasting my subscription's rate limits on simple "Hello" queries.
3. The Specialist: Claude Opus
I keep this in the stack for high-level brainstorming and creative writing, used only when I need that specific reasoning edge.

The Execution:
I’ve configured Chiti to dynamically choose the right "brain" for the task. If I ask a coding question, it automatically spawns a specialist session using GPT-5.2. For everything else, it defaults to the lightweight Flash model.
It’s been a fascinating experiment in balancing uptime with intelligence. I no longer worry about the bot going "dead" due to a rate limit, and my monthly spend is finally predictable.
The goal isn't just to have the smartest AI, it’s to build a system that stays online and executes exactly when you need it.
Hoping this works out!
I’ll share more on how it performs as I use it.
I’m also planning to explore other alternatives too, if you’re using a different stack, let me know!
