# Eleven v4 Turbo

elevenlabs, released 2026-09-28

**Verdict: conditional.** Conditional. Eleven v4 Turbo (id eleven_v4_turbo) is ElevenLabs' real-time speech model, stating a median inference latency of about 100 ms, excluding application and network latency, across 90+ languages via a Text to Dialogue WebSocket. The deciding caveat is that the latency figure is vendor-stated and untested by us, and $0.011 per 1K characters is a promo ending Oct 12 against a $0.04 list rate. Suits builders of voice agents and interactive characters. Last verified 2026-10-02.

## Pricing

- Input: $0.04 / 1K characters
- Output: Billed per character (single rate)
- Context: List $0.04 / 1K chars; median latency ~100 ms

## Strengths

- Real-time voice: the models page states a median inference latency of about 100 ms, excluding application and network latency
- Support agents, AI assistants and interactive characters, the use cases the models page names
- Streaming over the Text to Dialogue WebSocket, the endpoint the changelog lists for agents and interactive applications
- Multilingual output: 90+ languages, the same roster the models page lists for eleven_v4
- Long single-shot generations: the models page we read states no character limit for eleven_v4_turbo, so confirm before relying on long inputs (eleven_v4 lists 10,000 characters)
- Budgets built on the launch promo rate: the promo has ended and the pricing page shows $0.04 per 1K characters as the price
- Latency budgets that must include network and application time: the 100 ms figure excludes both
