- -
The short version
- Each has a real cost: AutoGen framework now in maintenance mode, no new features planned; Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention
- They diverge on capability: AutoGen covers Multi-agent orchestration, Comet ML covers Experiment tracking.
Where they differ
Only the attributes on which AutoGen and Comet ML actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated).

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
AutoGen
- Framework now in maintenance mode, no new features planned
- Steeper learning curve for advanced use cases
- Microsoft recommends new projects use Agent Framework instead
- Limited to Python and .NET platforms
Comet ML
- The free cloud tier caps data at 25,000 spans a month with 60 day retention
- Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
- Overage on Pro is $5 per additional 100,000 spans
- The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
- Pro MLOps is $19 per user per month and caps the team at 10 users
