Mistral Vibe (Remote Agents) + Mistral Medium 3.5
https://mistral.ai/news/vibe-remote-agents-mistral-medium-3-5
Vibe is Mistral's cloud-hosted coding-agent platform: each session runs in an isolated sandbox with task state, history, and approvals. Spawnable from CLI or Le Chat, with parallel execution. Local CLI sessions can be "teleported" to the cloud and resumed. Powered by Mistral Medium 3.5 (77.6% SWE-Bench Verified). Plugs into GitHub, Linear/Jira, Sentry, Slack/Teams.

When to use
Optimised for: async parallel coding agents with teleportable session state; SWE-Bench-leading model (77.6%); EU-jurisdiction stack
Anti-fit: not for non-Mistral stacks; not for users requiring full transparency of memory eviction policy; not for offline/air-gapped use
Pros & cons
Pros
Async parallel coding agents with teleportable session state; broad ecosystem integrations (GitHub/Linear/Jira/Sentry); SWE-Bench-leading model; weights open; EU-jurisdiction stack.
Cons
Vibe service closed; SWE-Bench claim is vendor self-report; no third-party reproduction yet; pricing tied to Pro/Team/Enterprise tiers; opaque memory eviction policy.

Other coding-agent memory in the catalog, ranked by inbound references.
- Devin (Cognition) T1
Structured Knowledge items stored server-side. Three-tier scope: repo-pinned (always injected), global (recall by relevance), org/enterprise (visible to org members). Auto-generates Repo Knowledge from repo structure each session; reads past session trajectories for self-improvement; writes notes for recurring scheduled tasks.
- Aider T2
Appends conversation turns to .aider.chat.history.md in project root. restore_chat_history defaults to false — no automatic replay into new sessions. Community /session save command for JSON state snapshots. .aider.conf.yml carries static preferences.
- Augment Code T1
Real-time knowledge graph indexed from connected repos + commit history + CI/CD + tickets + docs. Separate Agent Memory layer (Sept 2025) captures session decisions/corrections/goals as discrete items with developer review/approval UI. MCP endpoint exposes the graph. Acquired by Harness (2026-10-08): Harness bought select Augment Code assets, including Cosmos, the Auggie CLI and the Context Engine, and the team joined Harness. augmentcode.com now leads with Cosmos, a software-factory agent platform.
- Letta Code T3
Letta's stateful coding-agent harness: agents rewrite their own memory blocks and skills, version context in git via MemFS (syncable to GitHub) and reflect via a periodic /sleeptime 'dreaming' process. from Letta (MemGPT) team. letta-ai/letta-code is now the main Letta source (harness, terminal UI, App Server, channels); the Letta V1 API server was retired to the archive branch of letta-ai/letta.
- Replit Agent T1
No documented built-in persistent semantic memory store. Session duration expanded to 200 min (Agent 3); Agent 4 shifts toward persistent runtimes. Temporal used for orchestration durability, not semantic memory. Cross-session memory relies on filesystem + agent-written notes.
- agentmemory (rohitg00) T3
Self-hosted persistent memory layer that captures coding-agent activity and recalls it in later sessions, positioned on public benchmark results. #7 in TeleAI Awesome-Agent-Memory
