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.

One live feed in, captions, subtitles and AI dubs out for every audience
Send your existing SRT/MPEG-TS, CMAF or RTMP stream and get captions back in under two seconds without re-encoding video or adding caption hardware.
Human-verified accuracy keeps live captions fast and correct, with custom dictionaries for presenter names, players, places and specialist terms.
Deliver same-language captions, translated subtitles and AI dubbing from one feed, so a single broadcast reaches every market in its own language.
Vocalics AI voice dubbing recreates the speaker's tone and pacing in another language, suitable for live news, sports, events and live shopping.

Free / Open-sourceAlibaba Cloud's 4th-generation multimodal AI assistant and foundation model lineup (Qwen4-Max, Qwen4-Plus, Qwen4-Flash & open-weight Qwen4-27B) with 1M context.

Unifies hundreds of third-party models under a single API key, offering greater model choice than OpenAI's curated catalog.

Provides developer APIs for Zhipu AI's proprietary GLM models, serving as an alternative enterprise foundation model stack.

Free / Open-sourceAI transcription and meeting notes in 150+ languages

SpecialistOptimized for lightning-fast serverless execution of generative media and image models, rather than general text LLMs.

Specializes in high-performance serverless inference and dedicated GPU clusters for open-source models, bypassing closed commercial restrictions.
Free / Open-sourceLive AI interpretation, transcription, subtitles and dubbing in 125+ languages

SpecialistFocuses heavily on running and fine-tuning open-source vision and language models via simple APIs, unlike OpenAI's hosted closed models.
One OpenAI-compatible API for 500+ image, video, audio, and LLM models
Free / Open-sourceAI transcription, subtitles and video translation in one browser studio

SpecialistDelivers ultra-low-cost serverless inference for open-weight models, though with fewer enterprise orchestration tools than OpenAI.
