The short version
- Each has a real cost: Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention; Poe points-based pricing makes cost per message hard to predict across models.
- They diverge on capability: Comet ML covers Experiment tracking, Poe covers Multi-model chat.
- Prices and features above were last checked on 30 August 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Poe
- Points-based pricing makes cost per message hard to predict across models.
- Heavy usage of top-tier models can exhaust points quickly on lower plans.
- No native fine-tuning or persistent long-term memory across bots.
- Custom bots are limited to prompt engineering rather than full agent tooling.

Answered from the vendors’ own pages
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.
SourcePoe: How does Poe's pricing work?
Poe uses a monthly points system: each subscription tier grants a pool of compute points that are spent per message, with the amount depending on which underlying AI model is used.
SourceComet 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.
SourcePoe: Is there a free plan on Poe?
Yes, Poe offers a free tier with limited daily messages across a selection of models before users need a paid subscription for more access.
SourceComet 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.
SourcePoe: What do the paid subscription tiers cost?
Poe offers Starter at $4.99/month, Premium at $19.99/month, and Premium Plus at $49.99/month, each granting a larger monthly pool of compute points.
SourceComet ML: Does Comet.ml offer academic pricing?
Yes, a free Pro plan is available for academic users; verification is required via signup.
SourcePoe: What happens if I run out of points?
Once a subscription's monthly point allowance is exhausted, further use of premium models is limited until the points refresh or the user upgrades or purchases more.
SourcePoe: Can developers build on Poe?
Yes, Poe lets creators build and publish custom bots, and developers can connect their own model endpoints as bots via Poe's API.
