Workflow orchestration
Letta Code v0.34.12 lets an agent run Claude Code and Codex subagents on a connected computer rather than only on the local machine, and shows their tool calls as live progress.
One Letta agent can dispatch third party coding agents to other machines a team controls, so long coding jobs can be spread across computers from a single orchestrator.
Workflow orchestration
Letta Code's dynamic workflows, where the agent writes its own script to fan work out to many subagents, now run for both local and cloud agents. A new decide() step returns a choice, rating or yes or no answer with a confidence score, and each subagent can run on any connected model, including the team's own provider keys.
Teams can route and check subagent work with cheap, confidence scored judgments instead of a full agent call per item, which lowers the cost of large fan outs such as codebase reviews.
Memory / state
Letta released the open-source trajectory package, which normalizes coding-agent sessions from Claude Code, Codex, and Letta Code into a single JSON-compatible format. The schema captures user messages, agent reasoning, and tool results while stripping redundant payloads to reduce token usage by up to fivefold.
Teams using multiple agent harnesses can now aggregate session data into a standardized format. This structure powers Letta's background dreaming process, allowing agents to extract lessons from past experiences across different tools and write them into persistent memory.

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 1648 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 Oct 21, 2026, covering Equal AI, Kognitos, Findem.
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. The same entries are published as a free RSS feed at agenticindex.io/feeds/changes.xml, with one feed per ranking category listed at agenticindex.io/use-this-data.
