The short version
- Only Comet ML has a free tier, so it costs nothing to try first.
- Each has a real cost: Avathon the company rebranded from SparkCognition to Avathon and narrowed its focus after repeated reported layoff rounds, so reference checks and roadmap commitments made under the old name need reconfirming.; Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention
- They diverge on capability: Avathon covers Renewable Suite, Comet ML covers Experiment tracking.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Avathon
- The company rebranded from SparkCognition to Avathon and narrowed its focus after repeated reported layoff rounds, so reference checks and roadmap commitments made under the old name need reconfirming.
- Headcount is in the low hundreds against a product portfolio spanning renewables, vision, predictive maintenance and document AI, which is thin coverage per product line for enterprise support expectations.
- Model accuracy depends on having enough labelled historical failures, and sites with short data history or poor maintenance record-keeping get generic anomaly detection rather than useful failure prediction.
- Nothing is published about pricing or asset-count thresholds, so there is no way to judge whether a small fleet is even a viable customer without entering a sales cycle.
- It sits on top of your SCADA and CMMS rather than replacing them, so the integration and asset-hierarchy mapping work is a real project cost that the software subscription does not cover.
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

Questions people ask
- Is Avathon or Comet ML better?
- Neither clearly leads. Avathon starts at On request and Comet ML at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Avathon or Comet ML?
- Comet ML has a free tier; the other does not. Paid plans start at On request for Avathon and Free for Comet ML.
- Does Avathon or Comet ML run on more platforms?
- Avathon runs on Web, Cloud. Comet ML runs on Web, Linux, Mac, Windows.
- Can I use Comet ML for free?
- Yes. Comet ML has a free tier, so you can try it without paying. Avathon starts at On request.
- What is Avathon best used for?
- Avathon is most often used for a wind fleet owner wanting underperforming turbines ranked by lost megawatt hours rather than by alarm count, a solar independent power producer detecting inverter and string underperformance that falls below the scada alarm threshold, a manufacturer with years of historian data and failure records who wants failure prediction models trained on their own history, a site using cameras to detect missing personal protective equipment or unauthorised entry into restricted zones. Of those, a wind fleet owner wanting underperforming turbines ranked by lost megawatt hours rather than by alarm count and a solar independent power producer detecting inverter and string underperformance that falls below the scada alarm threshold are not what Comet ML is typically brought in for.
- What can Avathon do that Comet ML cannot?
- Avathon covers Renewable Suite, Loss attribution, Predictive maintenance models, Computer vision. Comet ML covers Experiment tracking, Code versioning, Model registry, Hyperparameter optimization.
Answered from the vendors’ own pages
Avathon: Is this the same company as SparkCognition?
Yes. SparkCognition rebranded to Avathon and refocused on industrial and government asset AI.
Comet ML: Does Comet.ml offer a free plan?
Yes, Comet.ml offers free tiers for both Opik (cloud observability) and MLOps platforms. Free Cloud Opik includes up to 10 team members and 25,000 spans/month. Free MLOps tier is limited to 1 user.
SourceAvathon: Which product is most mature?
The renewable energy suite for wind and solar underperformance, which has the longest production deployment history.
Comet ML: How many team members can use the free Comet.ml tier?
Free Cloud supports up to 10 team members. The Pro Cloud plan supports up to 50 team members at $19/month.
SourceAvathon: Does it need my historian data in the cloud?
Generally yes for model training and ongoing scoring, which is a security review item for utility and defence customers.
Comet ML: What is a span in Comet.ml pricing?
A span represents a single tracked operation such as model requests or function calls. Free Cloud tier includes 25,000 spans per month.
SourceAvathon: Can it work without historical failure records?
It will still do anomaly detection, but failure prediction models need labelled historical failures to be worth the deployment cost.
Comet ML: Does Comet.ml offer academic pricing?
Yes, a free Pro plan is available for academic users; verification is required via signup.
