Frequently asked questions about the LLM comparison
Changelog
Compare up to five LLMs on this page
- The multi-model comparison is now a section of this page, directly below the overall index
- Alternatives to a model are now listed in its model profile
Overall index, version 5
- Models with few test series are pulled less towards the middle and now land close to their value with full data
- Gemini 4 Carbon is now in second place
- Five models no longer have a place in the overall index
- Added a block with data and feeds
Recommendations by popularity
- Duel pages, model profiles, vendor pages and this hub now recommend comparisons in one shared block, ordered by how often people compare the models
- Each model's direct predecessor and successor are always listed, and every block has a picker for your own comparison
Show older versions (19)
One rank per model
- Ranks in the overall index and in the areas now show one place in score order, such as rank 14 of 95, instead of a range; whether two models are level is still decided by the 200 recalculations
Intelligence vs. price, provider race and recent changes
- Shows the overall index as columns in the providers' colors, with provider logos and a model picker; the full list with rank ranges stays below
- Replaced the price-performance map with the intelligence vs. price chart: overall index against blended price, the most attractive area and the line of the best intelligence for the price
- Added a provider section with the best model of every provider that has at least three models in the index
- Added a log of new models and confirmed API price changes from the last 45 days
- The former AI leaderboard now redirects to the overall ranking on this page
- Replaced the radar chart question in the FAQ with questions on price changes and on “level”
- Removed Claude Mythos 5 and Mythos 5.1 from the comparison because neither model is publicly available; their former matchup pages redirect to this page
One overall index for the whole site
- The overall index is now the benchmark meta-score v3 and matches the AI model directory
- A one-factor model combines every reviewed test series; core areas carry 75% and specialist domains 25% of the overall weight
- Every score shows its standard error, and rank ranges come from 200 recalculations with randomly redrawn test families
Overall index on the widest result series again
- Per-model run settings such as temperature or reasoning effort no longer split an evaluator's result series
- Explained in the FAQ which settings may differ within a result series
