Mutual Exclusivity
What it is: Grouping guides and surveys into a mutual exclusivity set ensures each end-user sees at most one from the group. The primary use case is platform-specific announcements: create a version for iOS and another for Android, add both to the group, and users see only the version that matches their device.

Temperature Parameter: Increased Maximum The maximum allowed value for the temperature parameter for Chat Completions has been increased from 1.5 to 2.0. This aligns with the range supported by OpenAI, Fireworks, and other major LLM providers. Higher temperature values produce more random and creative outputs.

developer Message Role (gpt-oss-120b) The Chat Completions API now supports the developer message role for gpt-oss-120b, aligning with the OpenAI API message format. The developer role is functionally equivalent to system , the system role remains supported for backwards compatibility. Other models do not support the developer role.
TTS speak speed (Early Access)
You can now control the speaking rate of Deepgram TTS in the Voice Agent API using the agent.speak.provider.speed parameter. This parameter accepts a float value between 0.7 and 1.5 , with 1.0 as the default.
Updated LLM models
New OpenAI models , Two new models are now available in the Standard pricing tier: gpt-5.4-nano gpt-5.4-mini Gemini 2.0 Flash deprecated , The gemini-2.0-flash model is now deprecated. We recommend migrating to gemini-2.5-flash or a newer Gemini model. See the Google models table for alternatives.
Access - Code Mode for MCP server portals
MCP server portals support Code Mode MCP server patterns , a technique that reduces context window usage by replacing individual tool definitions with a single code execution tool. Code Mode is turned on by default on all portals. To turn it off, edit the portal in Access controls > AI controls and turn off Code Mode under Basic information .
Access - Context optimization for MCP server portals
MCP server portals support two context optimization options that reduce how many tokens tool definitions consume in the model's context window. Both options are activated by appending the optimize_context query parameter to the portal URL. minimize_tools Strips tool descriptions and input schemas from all upstream tools, leaving only their names.

New Filters for List Session Replays
What it is: Two new filters are now available on the List Session Replays API endpoint. 'amplitude_id' (integer) returns replays tied to a specific Amplitude user ID. 'replay_id' accepts up to 100 IDs in 'device_id/session_id' format and fetches those sessions directly, bypassing pagination.
Improvements to Distributions
What it is: Frequency charts, histogram charts, session length, and time-to-convert now support normalization, PDF, and CDF views. Normalization scales each series so its bars sum to 1, making groups with different sample sizes directly comparable , for example, U.S.
Even More External MCP Tools, Agent Skills, and the MCP App!!
What it is: Coverage has expanded from analytics-only to Session Replays, Agent Analytics, Feature Flags, and Web Vitals, including end-to-end error debugging via autocapture data.
Multi-action CTA's for Guides & Surveys
What it is: Buttons in Guides and Surveys can now execute multiple actions in sequence rather than just one. When a user clicks, the step transition fires immediately, and additional actions (opening a URL, clicking a page element) follow in order.
Edit guide and survey positions without leaving Preview mode
What it is: The Guide Preview now includes an Edit button. Click it to adjust form factor options like position and layout, then save to see changes reflected in both the Preview and the Dashboard right away.
Advanced Channel Classifier Template
Description: Amplitude’s enhanced out-of-the-box channel classifiers automatically group traffic from sources and referrers like Paid and Organic Search, Email, Affiliates, LLM channels, and more. Why: Your dashboards and Global Agent clearly show trends and impact from every channel investment without any added analytics set-up.
Global Agent Audit Tab
What it is: Good news! Admins can now view all user activity within Global Agent across their organization through a new Audit Tab in AI Controls. The table surfaces all threads, giving admins insight into how users are interacting with Global Agent, as well as the ability to monitor usage and verify things are running smoothly.
AI Feedback Ingestion API
What it is: The HTTP API Source accepts feedback over HTTP in three formats: standalone comments, threaded conversations (like support tickets with replies), and call-style flows structured as turn-by-turn exchanges or full transcripts. Feedback lands in AI Feedback and gets analyzed alongside data from native connectors.
