The short version

  • Only ElevenLabs has a free tier, so it costs nothing to try first.
  • Each has a real cost: ElevenLabs number pronunciation errors: '200000' reads as 'twenty thousand thousand' instead of '200,000'; OpenAI API cost scales with tokens rather than with seats, so a successful feature's bill grows with its adoption, and an interface that lets users paste long documents has no natural ceiling on spend unless you build one yourself.
  • They diverge on capability: ElevenLabs covers Text-to-speech, OpenAI API covers Text and reasoning models.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ElevenLabs

  • Number pronunciation errors: '200000' reads as 'twenty thousand thousand' instead of '200,000'
  • Voice cloning requires professional-grade audio quality; no upfront guidance on technical requirements
  • Email-only support with 5-14 day response times for complex issues; no phone support
  • Pricing unpredictability: actual usage often exceeds advertised estimates due to regenerations needed for quality

OpenAI API

  • Cost scales with tokens rather than with seats, so a successful feature's bill grows with its adoption, and an interface that lets users paste long documents has no natural ceiling on spend unless you build one yourself.
  • Models are deprecated on the vendor's timetable, and a fine-tuned model built on a retired base goes with it, so the tuning work and the data curation behind it must be redone rather than migrated.
  • Behaviour shifts between model versions in ways no test catches unless you wrote one, so prompts tuned over months against a particular snapshot can regress quietly on migration, which makes an evaluation suite a prerequisite rather than an improvement.
  • It cannot run inside your own network, so data residency requirements, air-gapped environments and contracts forbidding third-party processing rule it out regardless of the provider's own security posture.
  • You inherit its availability and its rate limits, so a provider incident is an outage in your product and a traffic spike can be throttled at precisely the moment the feature is proving itself.

Answered from the vendors’ own pages

ElevenLabs: Does the free plan include commercial usage rights?

No. The free plan provides 10,000 characters monthly and access to 3 custom voices, but excludes commercial license. Commercial usage rights are only available on paid Starter plan ($5/month) and above.

Source
OpenAI API: Is my data used to train the models?

API inputs and outputs are not used for training by default, which differs from the consumer product. Retention periods and enterprise terms change, so read the current data usage policy rather than trusting a summary.

ElevenLabs: How many languages does ElevenLabs support?

ElevenLabs supports voice generation in 32+ languages. Professional Voice Cloning (PVC) allows you to create a digital replica of your voice that works across these 32+ languages while maintaining emotional register and prosody.

Source
OpenAI API: Can I run these models on my own hardware?

No. The weights are not distributed. If self-hosting is a requirement, you are looking at open-weight models instead, with the operational and quality trade-offs that implies.

ElevenLabs: What are the requirements for voice cloning?

Professional voice cloning requires high-quality audio with RMS between -23dB to -18dB, no background noise, consistent microphone distance, and proper compression. Without meeting these technical requirements, the cloned voice sounds robotic or distorted. ElevenLabs does not disclose these requirements upfront.

Source
OpenAI API: How is it priced?

Per token, with input and output priced differently and each model priced differently. Batch processing and cached input prefixes reduce it. The practical consequence is that your bill is a function of prompt design, not just of request count.

ElevenLabs: How is pricing calculated?

ElevenLabs uses a credit-based system where monthly character limits determine your plan. Free plan has 10,000 characters/month. Starter tier ($5/month) provides 30,000 characters. Creator ($22/month) includes 121,000 credits. Annual billing offers approximately 17% savings (2 free months equivalent).

Source
OpenAI API: What is the difference from Azure OpenAI Service?

The same model family delivered by Microsoft under an Azure contract, with Azure identity, networking and regional controls, and a different release cadence for new models. Enterprises with an Azure agreement often choose it for procurement and data residency reasons rather than technical ones.

ElevenLabs: What happens if I exceed my monthly character limit?

Exceeding your monthly quota requires upgrading to a higher plan. Users report pricing unpredictability, with actual usage averaging 220-280 credits per 1,000 characters when accounting for regenerations, often exceeding advertised usage estimates.

Source
OpenAI API: How do I keep the cost under control?

Cap input length, cache repeated prefixes, route easy requests to smaller models, use the batch path where latency does not matter, and set per-user limits before launch rather than after the first surprising invoice.
