Speech-to-text and audio intelligence API for production voice products
Stream audio over WebSocket for live captioning or submit files via REST for batch transcription, supporting MP3, WAV, FLAC, Opus, and most other formats.
Automatic, accent-sensitive language detection across 100+ languages, including code-switching for conversations that move between languages mid-sentence.
Speaker diarization, named entity recognition, PII redaction, sentiment analysis, and summarization, each billed only when you enable it.
Feed transcripts directly into a large language model, either Gladia-hosted or a model you bring yourself (BYOM), to generate summaries and structured outputs.
Enterprise developer platform and API for deploying GPT-6 Astra, Sol, Luna, and realtime multimodal agents.
Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
Provides direct API access to Google's Gemini models with generous free prototyping tiers, but lacks OpenAI's ecosystem breadth.
