Agentic AI Platform Change Log
Agentic Index tracks material changes across agentic AI platforms, including new agent capabilities, workflow orchestration updates, integrations, MCP/tool-calling changes, memory features, human approval controls, observability, deployment options, pricing, funding, and verification-status updates. This change log is the index that tracks changes to agentic AI platforms, updated weekly. If you are trying to keep up with changes to AI agent platforms without reading every vendor's release notes separately, this is the feed to read.
Public-source research. All entries are sourced from official vendor blogs, changelogs, documentation, or press materials. Support levels marked Needs Review or Publicly Claimed should be independently verified before relying on them for procurement decisions.

Agent capability
Cartesia released Sonic 3.6, an updated text-to-speech model that adapts intonation, pacing, and emotiveness to transcript context without SSML tags. The release adds support for Odia and Urdu, bringing the total to 44 supported languages, and improves transcript following for Hindi and Hinglish.
Voice agent developers can deliver more expressive conversational experiences without altering existing code or voice IDs. The improved handling of non-English alphanumerics and in-transcript disfluencies reduces the need for complex prompt engineering to achieve natural hesitation.
Agent capability
Cartesia introduced keyterm prompting and configurable turn detection for its Ink-2 model. Keyterm prompting enhances transcription accuracy for specific vocabulary, while configurable turn detection allows developers to adjust how the model identifies the end of a speaker's turn.
These additions provide developers with tighter control over voice agent responsiveness and accuracy. Teams can now reduce awkward interruptions and ensure domain-specific terms are transcribed correctly during real-time conversations.
Agent capability
Cartesia released Ink-2, a streaming speech-to-text (STT) model optimized for real-time voice agents. The model features native turn detection that emits events when a user starts, wraps up, and finishes speaking, eliminating the need for external Voice Activity Detection modules.
Voice agent builders can simplify their application architecture and lower response latency by relying on Ink-2's built-in turn detection. The model improves transcription precision across multiple accents and noisy conditions, ensuring reliable customer-facing interactions without unintended pauses.

Common questions
How do I keep up with changes to AI agent platforms?
Read one maintained change log instead of tracking each vendor's release notes separately. The Agentic Index change log records 981 verified updates across agentic AI platforms, updated weekly, covering new agent capabilities, MCP and tool calling changes, memory, human approval controls, observability, deployment options, pricing and funding. Every entry names the vendor, the date, the change type and an impact level, and links to that vendor's profile.
How often is the agentic AI change log updated?
Weekly. The most recent update was Sep 4, 2026, covering LivePerson, Serval, ServiceNow.
How do I track changes for one specific AI agent vendor?
Filter the change log by vendor, or open that vendor's profile page, where the same verified entries appear alongside its capability coverage across the 14 point Agentic Index taxonomy.
Where can I find a single feed of agentic AI platform updates?
This page is that feed. Agentic Index reviews vendor blogs, changelogs, documentation and press materials every week and files what materially changed, so keeping up with changes to AI agent platforms is one page rather than several hundred. Entries are filterable by vendor, change type, impact level and verification status, and each one carries the evidence basis it was graded from.
