Every agentic-AI vendor is shouting that their agent is the one to trust your workflows to. The truth is messier: the leaderboard changes by the week, and the model that's best at chat is rarely the model that's best at acting — reliably, repeatedly, without quietly breaking your pipeline. This is us walking through the chaos — 12 current agent leaders, graded on the four things that actually break people.
Writes code, moves files, calls tools, runs a business. FUBARO is built on agents (this report is drafted, staged, and versioned by one), so we've got a personal stake in who's actually trustworthy at that. We grade on four axes because these are the four ways agents fail in production:
Does it do the job the 10th time like the 1st, or degrade?
Does it actually act, or just narrate what it would do?
How much real work before you have to babysit?
Can you leave it without rebuilding everything?

Pricing = live API list, $/1M tokens (input → output), from a 2026-07 audit. "Agent-readiness" = our 4-axis synthesis into a single FUBAR score. Green row = our daily workhorse.
Every open/specialist option flips that. It's not coincidence, it's architecture. The moment a model is the product, keeping you in the garden is the feature.
For real agent work, the fast cheap models (DeepSeek V4 Flash at $0.14/$0.28, Gemini Flash, Grok 4.3) out-earn the $30-output flagships on bang-for-buck for the 90% of tasks that are routine.
Chat is won by the smooth frontier labs. Code is won by the specialists. Cron/automation is won by the cheap reliable ones. Route the task to the model that earns it.
Exit freedom is the axis nobody markets — and it's the one that costs you real money when the vendor jacks the rate.
The branded frontier agents are fantastic chat partners and mediocre employees. The open + specialist stack is the opposite — and for a business, that's the trade that pays.
We run FUBARO on exactly what we preach: self-hosted, multi-model, routing each task to the model that earns it — while keeping a door open on every one. We grade everything on exit freedom first. A model you can't leave is a bill you can't refuse.
We run ourselves on this exact stack — honest, cheap, exit-free. Hire us to run yours the same way.
