Model B

Simulate accuracy gains vs added response time & token cost

Mode: Medium (16k budget)

Reasoning models “think before answering” by generating internal reasoning tokens. Higher effort improves math, coding, and logic accuracy, but increases response delay and token costs.

Frequently Asked Questions

Which is better overall, Auto Router (Beta) or Claude Fable 5?
We do not have preference Elo for both models, so we do not declare an overall winner. Compare the metrics that exist.
Which is better at coding, Auto Router (Beta) or Claude Fable 5?
SWE-bench is missing for at least one model, so we do not rank coding from a single number.
Which is cheaper to run in production?
Auto Router (Beta) output tokens are $-1,000,000/1M versus $50/1M. Input prices and retry rates still move the real bill.
Which is faster, Auto Router (Beta) or Claude Fable 5?
We do not have TTFT for both models.
Which has the larger context window?
Auto Router (Beta) accepts 2M tokens versus 1M.
Can I self-host either model?
Neither model is marked open-weights here. You are comparing hosted APIs.
Are these scores from CompareLLM’s own evals?
No. V1 aggregates public leaderboards (and optional first-party latency pings). Each cell names its source and date. Read /methodology.
What does preference Elo mean on this page?
Preference Elo is a crowd vote from LMArena / Arena. People see two hidden answers and pick the one they like more. The model that wins more often gets a higher Elo. That means people preferred it — not that it passed a school test. It is not SWE-bench, not accuracy, and not a number we invent. Auto Router (Beta) and Claude Fable 5 Elo cells are dated snapshots from the named source — we do not compute Arena ourselves.
