HUME AI

Voice AI gets 2x cheaper, 40% faster

Recaply: Hume AI just launched Octave 2, and it's a game changer for voice AI. The second generation model delivers speech in under 200 milliseconds while cutting costs by 50%. This upgrade makes realistic voice technology accessible for everything from customer service to gaming.

Key notes:

• Octave 2 generates audio 40% faster than its predecessor, responding in under 200ms for near-instant voice interactions.

• Pricing drops to half the cost of Octave 1, with dedicated deployments reaching under a cent per minute of audio.

• The model understands emotional tone more deeply, knowing when to whisper, shout, or speak calmly based on context.

• New EVI 4 mini brings these capabilities to speech-to-speech applications for smoother conversational experiences.

• Enhanced pronunciation handles uncommon words, numbers, and symbols more reliably than before.

Impact: With faster response times and lower costs, Octave 2 opens doors for large-scale voice AI applications. Businesses can now deploy realistic voice technology without breaking the bank, while users get seamless experiences that feel genuinely human.

MICROSOFT

Open-source AI agent platform debuts

Recaply: Microsoft unveiled Agent Framework, a free toolkit designed to help developers build sophisticated AI agent systems. The platform tackles a common challenge: how to move AI experiments into real business applications. Agent Framework provides the structure needed for multiple AI agents to work together, handle interruptions, and operate safely in regulated industries.

Key notes:

• The framework bridges research innovation from Microsoft Research with production-ready enterprise features.

• Companies can deploy agents that collaborate, like one agent researching data while another analyzes and validates results.

• Built-in observability tools let teams track every decision and action agents make across workflows.

• Human-in-the-loop features allow managers to approve sensitive operations before agents execute them.

• Integration with Azure AI Foundry provides secure hosting with compliance controls for regulated sectors.

Impact: This launch represents a shift toward standardizing how companies build AI agent systems. By offering both creative flexibility and enterprise controls in one package, Microsoft reduces the technical barriers that have kept many organizations from adopting multi-agent AI. The result could be faster innovation across industries.

PERPLEXITY

Inside Perplexity's fast AI weight system

Recaply: Perplexity just dropped its first research publication with a clever solution to a gnarly technical challenge. When training large AI models with reinforcement learning, the system constantly shuffles updated weights between training computers and inference computers. Most frameworks take forever because they route everything through a single choke point. Perplexity's team built a smarter highway system for this data traffic.

Key notes:

• The weight transfer system moves data from 256 training GPUs to 128 inference GPUs in under 2 seconds.

• Uses one-sided RDMA WRITE operations that let source GPUs write directly into destination memory.

• Creates a static schedule at startup that maps which GPU sends what data to which destination.

• Pipelines four types of operations: host-device copying, GPU computation, RDMA networking, and control signaling.

• Inference GPUs never get interrupted or notified during transfers, keeping them focused on generating outputs.

Impact: Smart engineering often beats throwing more hardware at a problem. By rethinking how data flows between systems, Perplexity made reinforcement learning post-training practical at scale. This kind of infrastructure work rarely gets headlines but determines which AI applications actually work in production versus staying stuck in research labs.
