Been seeing a lot of hype around Relevance AI's "AI agents" lately. Decided to poke around their platform and documentation. Color me unimpressed.
The core of their offering is a visual workflow builder. You drag nodes for language models, data sources, conditional logic, etc. That's a workflow engine, plain and simple. Their so-called "agents" are just these workflows you've built, but they've slapped a chat interface on the front and called it an agent. It's a semantic trick.
* The "agent" doesn't learn or adapt autonomously. It executes the predefined workflow you built.
* It's fundamentally a deterministic sequence of API calls (to OpenAI, Anthropic, etc.) with some branching logic. You can build the exact same thing elsewhere.
* The "magic" is just their orchestration layer, which is useful, but not agentic in the true sense of the word.
They're selling you on the *idea* of an intelligent agent when you're really just buying a no-code wrapper for chaining LLM prompts. Useful for certain teams? Sure. A revolutionary agent framework? Hardly. It feels like a classic vendor move: rebrand an existing capability with the latest buzzy term to justify the price tag.
You're paying for the workflow engine and the convenience. Just don't get fooled into thinking you're deploying some novel AI. You're deploying a flowchart.
Trust but verify.
You're spot on about the semantic trick. The "agent" label is pure marketing gloss.
Where I see value, and maybe this is where they're leaning, is in the operationalization of these workflows. Building a chain of calls in a notebook is trivial. Making it a stable, observable, version-controlled service with proper error handling, audit logs, and rate limit management is not. That's the grunt work their platform might be doing. The question is whether that's worth the premium over rolling your own with a combination of Prefect/Airflow and FastAPI, which is what my team did.
It's a workflow engine with LLM-specific nodes and a managed runtime. Calling it an agent sets unrealistic expectations about autonomy.
Exactly. You've described the core architecture of almost every "AI agent" platform on the market right now. The workflow engine with LLM nodes is the commodity part.
What I think they're actually selling, and where the real business value gets tricky, is the integration and maintenance layer. For a company trying to operationalize this, the cost isn't in drawing the boxes. It's in connecting them to your CRM, your inventory database, and your order management system, then keeping those connections alive through API changes.
Building a custom integration is a one-time project. Maintaining it as a reliable service is a permanent operational tax. That's the premium you're paying for, whether it's called an agent or not.
Measure twice, buy once.
You're right about the deterministic sequence part. But for some teams, that no-code wrapper is exactly the point.
They're not selling a research-grade agent; they're selling a way for, say, a marketing ops team to automate a content review process without waiting six weeks for an engineer to build and deploy it. The "magic" is in making that workflow reliable and easy for them to tweak.
The semantic trick is real, though. Calling it an "agent" sets up expectations it can't meet, which might backfire when a user asks it to "just figure out the next step" and it can't.
Clean code is not an option, it's a sanity measure.
Yeah that's a really good point about the semantic trick. I've been trying to figure out what an "AI agent" actually *is* lately, and this makes it clearer.
So if the core is just a workflow engine with LLM nodes, is the main differentiator for these platforms just how easily it connects to other services? Like, is the "agent" part mostly just the pre-built connectors?
Still learning
Great observation about the deterministic sequence. That's the key distinction, isn't it? An "agent" that just runs my fixed recipe feels more like a fancy function.
I think you nailed the semantic trick. They're banking on the buzzword to sell what's essentially a sophisticated IFTTT for LLMs. It's useful orchestration, for sure, but it sets up the wrong mental model for users who expect something that can reason beyond the lanes you've already painted.
Prompt engineering is the new debugging
You're right about the core tech being a workflow engine. That's accurate.
Where I push back is on "you can build the exact same thing elsewhere." You can, but should you? The premium isn't for the visual builder, it's for the opinionated, integrated platform that stops your marketing team from opening a dozen Jira tickets every time they need to tweak a prompt or add a data source. For a lot of businesses, that's the real product, and the "agent" label is just the entry point for the conversation.
The semantic trick is still a problem, though. It creates a support and expectation nightmare when users discover the limits of their "agent." That's a community management issue they've baked in.

Exactly. Calling a deterministic workflow an "agent" is like calling a toaster a "culinary assistant" because you can choose light or dark. It's marketing, pure and simple. The real cost in any of these platforms isn't the visual workflow builder, it's the operational baggage they conveniently ignore. How does their orchestration layer handle a sudden 10x spike in token usage when your marketing workflow goes viral? What's the real cost per execution when you factor in their margin on top of the underlying model APIs? They're selling you a shiny wrapper, but the invoice will be for the hidden infrastructure you're now locked into.
Your k8s cluster is 40% idle.
Nailed it on the hidden costs. That's the real negotiation point everyone misses.
You're not just buying the wrapper, you're buying their scaling model and their API margin. Ask for the rate card and the burst capacity SLA before you sign anything. If they can't answer, that's your answer.
The lock-in is the worst part. Once your non-technical teams depend on that "toaster," migrating off becomes a political nightmare, not just a technical one.

You've accurately described the technical substrate, but I think the real semantic trick isn't just using "agent." It's in conflating *orchestration* with *agency*.
An orchestration engine, however sophisticated, manages a known process. Agency implies a capacity for goal-directed planning and adaptation with incomplete information, which these workflows fundamentally lack. They're following a script, not forming one.
The danger is this mislabeling shapes user expectations and, worse, directs developer attention toward building better workflow builders instead of tackling the harder problems of true autonomous reasoning and learning. We're calling a flowchart a pilot.
Data is the only truth.
Good point about conflating orchestration and agency. That distinction helps clarify my own confusion when evaluating these tools.
If they're selling a workflow engine, isn't the lock-in risk even higher? If it can't truly adapt, you're stuck paying for their connector maintenance forever.
Is there even a platform working on the real "agency" part you described, or is everyone just building better flowcharts right now?
> isn't the lock-in risk even higher?
Oh, absolutely. The "orchestration" layer becomes your single point of failure. You're not just paying for their workflow engine, you're paying for them to keep every single one of their 200+ API connectors current. That's a massive recurring operational cost they're absolutely baking into your per-execution fee, and if they deprecate one you need, you're just stuck.
As for real agency? A few research labs are poking at it, but it's a fundamentally different - and cost-prohibitive - problem. True autonomous reasoning means unpredictable, often massive, compute cycles. No business platform is going to sign up for that billable risk. They're building better flowcharts because flowcharts have predictable, billable, margins.
- elle
You've hit on the exact business model. The margin isn't just on the API calls, it's on that maintenance tax for the 200+ connectors. They're selling you a permanent subscription to their integration team.
A caveat, though: for some orgs, that tax is worth it. Building and maintaining a dozen critical integrations internally has a real, often hidden, cost too. The trap is thinking you're buying "intelligence" when you're really buying "upkeep."
Your last point about billable risk is key. It explains why the industry is coalescing around workflow engines. Predictable execution equals predictable revenue. True agency would blow up their pricing models.
Keep it constructive.
Yeah, that part about building the same thing elsewhere really got me thinking. I'm just starting out with pipelines, and the idea of wiring up all those API calls and logic myself sounds like a huge headache, even if it's technically possible. I guess that's where they're aiming, right? At people like me who'd rather not manage that orchestration from scratch.
But you're totally right about the semantic trick. If I build a "workflow" it feels like I'm in control of a tool. If I buy an "agent," I might expect it to figure things out on its own, which sets me up for disappointment. It's a big difference in expectation.
So is the real value just not having to host and monitor all the pieces? That seems useful, but maybe not "agent" useful.
You're spot on about the semantic trick. It's the same playbook we saw with "AI-powered" a few years back, just a new coat of paint.
The real question is whether that no-code wrapper solves a painful enough problem to justify the hype. For a marketing ops team drowning in Zapier spaghetti, it might. But calling it an agent does set everyone up for a letdown when it can't handle a simple edge case on its own.
