Every fact about Vision Agents below carries the source it came from and the day we checked it.

Vision Agents does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Vision Agents quote, it is the fastest way for us to close that gap.

On capabilities, Vision Agents covers bring-your-own llm, bring-your-own tts voice, self-host / on-prem option, and api-first (full lifecycle via api), and does not offer no-code agent builder. Each of those is verified against Vision Agents's own docs or dashboard, not marketing copy.

On performance, Vision Agents reports a median end-to-end latency around 30 ms. Latency figures are vendor claims until we measure them ourselves, and they are labeled that way on the Vision Agents fact sheet, so treat them as a starting point rather than a guarantee.
