The AI terms that
actually matter.
Clear, technical definitions of 62 key concepts — written by AI engineers, not marketers.
NVIDIA Parakeet TDT
NVIDIA's Parakeet TDT 1.1B is the fastest open-source ASR model available, achieving an RTFx near 2,000× real-time — processing audio 6.5× faster than Canary-Qwen at the cost of some accuracy.
Read definitionOmniFlatten
OmniFlatten is a full-duplex, end-to-end GPT model for seamless voice conversation that converts multi-stream speech and text into a single flattened token sequence, enabling a standard LLM backbone to handle simultaneous listening and speaking.
Read definitionOmniVoice
A massively multilingual open-source TTS model by Xiaomi supporting 646 languages with zero-shot voice cloning and voice design, running 40× faster than real-time.
Read definitionOpenClaw
OpenClaw is an open-source, local-first autonomous AI agent that runs as a persistent daemon on your own hardware, connecting to any LLM backend and operated through messaging platforms like WhatsApp, Telegram, or Discord.
Read definitionOrpheus TTS
A Llama 3-based open-source TTS model by Canopy Labs with human-level expressiveness, inline emotion tag control, zero-shot voice cloning, and real-time streaming — the highest-quality open voice model for conversational AI.
Read definitionPhysical AI
Physical AI refers to embodied artificial intelligence systems designed to sense, comprehend, and interact directly with the physical world, bridging the gap between digital cognition and real-world action.
Read definitionPrompt Engineering
Prompt engineering is the practice of designing and refining the text inputs given to an AI model to reliably produce accurate, useful, and well-formatted outputs — without changing the model's weights.
Read definitionPrompt Injection
Prompt Injection is a critical vulnerability in Large Language Models (LLMs) where malicious, untrusted instructions are embedded into user inputs or external data to manipulate the model into ignoring its safety guidelines and executing unintended actions.
Read definitionQwen 3.5
Qwen 3.5 is Alibaba Cloud’s open-weight LLM series, delivering strong reasoning, long-context support, coding performance, and multilingual capabilities for enterprise AI and agentic workflows.
Read definitionQwen3-ASR
Alibaba's Qwen3-ASR is a state-of-the-art open-source automatic speech recognition model family that outperforms most commercial and open ASR systems on standard benchmarks as of 2026.
Read definitionReinforcement Learning from AI Feedback (RLAIF)
RLAIF is a post-training alignment technique that replaces human annotators with a capable AI model to evaluate, critique, and rank outputs, enabling scalable, faster, and more cost-effective alignment of Large Language Models.
Read definitionReinforcement Learning from Human Feedback (RLHF)
RLHF is the training technique that transforms a raw language model into a helpful, instruction-following assistant by using human preference judgements to shape model behaviour — the method behind ChatGPT, Claude, and most frontier chat models.
