Axiom vs Cortex: at a glance
What is Axiom?
Axiom makes agent work checkable, and points alerts straight at coding agents
Axiom's October releases split between agent plumbing and trace analysis. Monitors can now alert Cursor, Claude Code, Amp and ChatGPT, MCP links open the exact saved result an agent returned, and new skills let agents ingest data even before an organization exists. On the trace side, Critical Path, Service Map and Statistics views arrived within a week, and labels now organize resources and give agents context.
What is Cortex?
Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.

Axiom makes agent work checkable, and points alerts straight at coding agents
◆ Current state
Axiom's October releases split between agent plumbing and trace analysis. Monitors can now alert Cursor, Claude Code, Amp and ChatGPT, MCP links open the exact saved result an agent returned, and new skills let agents ingest data even before an organization exists. On the trace side, Critical Path, Service Map and Statistics views arrived within a week, and labels now organize resources and give agents context.
◆ Where it's heading
The agent track has moved from access to accountability. Saved result links and Open in Axiom links exist so a person can inspect what an agent saw and built, and notifier delivery history applies the same scrutiny to alerts. Sending monitor alerts directly to coding agents closes a loop from detection to attempted fix without a human relay. The trace work is a reminder that the product is still being built for human investigators as well.
◆ Prediction
Expect further notifier types and agent skills. Whether alerts sent to coding agents become a measured remediation workflow is unclear from these entries, which describe delivery rather than outcomes.
Cortex
2.5ANALYTICS
Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
◆ Current state
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.
◆ Where it's heading
The storage arc toward Parquet continues: after 1.21 made Parquet a Store Gateway query mode, 1.22 shards files that exceed column limits. A second arc is protecting shared clusters from heavy tenants, through query eviction, resource-based throttling and concurrent data-byte limits on store gateways. The cleanup is the maturity arc from 1.21 carried further: no-op flags that were tolerated for releases now fail at startup.
◆ Prediction
1.22.0 final should follow rc.3, which added only two fixes. Operators should expect upgrade failures from leftover deprecated flags, and the release notes tell them to grep runtime configs before upgrading.
