Mistral Agents API
https://docs.mistral.ai/studio-api/agents/introduction
Mistral's Agents API provides persistent conversation state across turns and sessions; runtime maintains branching conversation trees. Memory is implicit in the stateful session model rather than a separate store — agents can branch, continue prior discussions, and accumulate tool-call history without manual tracking.

When to use
Optimised for: EU sovereign AI + branching conversation trees
Anti-fit: not for self-hosted-only deployments
Pros & cons
Pros
Fully managed — developers need no external state store for session continuity; branching conversations allow parallel reasoning paths.
Cons
Closed infrastructure; no published architecture detail on how memory is stored/retrieved/evicted; no peer-reviewed evaluation of memory accuracy or long-term drift.
Claims & capabilities
Vendor-reported seamless multi-step workflow support; agents handle complex task sequences across multiple sessions.

- Gemini Enterprise Agent Platform Memory Bank (rebrand of Vertex AI Memory Bank) T1
GA at Google Cloud Next 2026 (2026-04-22). Vertex AI rebranded as Gemini Enterprise Agent Platform; Memory Bank now "Agent Platform Memory Bank" with new continuous event-streaming + automated memory generation triggered by configurable criteria (event count or idle time). Backed by Agent Runtime that supports long-running agents that maintain state for days. Note: separate "Memory Profiles" feature reported in TheNextWeb but not surfaced in official Google Cloud release notes — treated here as unconfirmed.
