On this site, ox-alpha-max, stealth/ox-alpha, and ox-alpha refer to the same Ox Alpha product under different public naming contexts. LiveBench identifies the Fable record as Claude Fable 5 Max Effort; “Max Effort” is part of the displayed evaluation configuration and is retained here.
The leaderboard release does not replace provider documentation. Confirm current context limits, modalities, API parameters, pricing, data handling, and availability with the provider serving the route you plan to use.

Ox Alpha benchmark vs Fable 5 is one question, not two pages.
The benchmark comparison shows Fable 5 ahead across all seven categories in this particular release. It does not tell you whether the quality difference justifies a provider’s current API price for your task, or whether a route will meet your latency, privacy, tool, and reliability requirements.
For an API comparison, run both models with the same prompt set, context, output budget, tools, retries, timeout policy, and scoring rubric. Report actual provider billing, latency, and failures separately. See the benchmark interpretation guide for the evidence checklist.
When should you choose Ox Alpha or Fable 5?
| If you prioritize | Start with | Why |

| Published quality score | Fable 5 | It has the higher Overall and every displayed category value in this snapshot. |
| Testing the documented Ox Alpha route | Ox Alpha | The Tokenra API reference defines the integration boundary to validate. |
| Long-horizon or agentic coding | Run both | Tool permissions, context selection, retries, and review controls can change the result. |

To test Ox Alpha in the documented route, continue to the Tokenra API reference and keep credentials server-side.
Ox Alpha vs Fable 5 questions.
Is Ox Alpha better than Fable 5?
On the LiveBench-2026-06-25 snapshot, Claude Fable 5 Max Effort has the higher Overall score and higher values in every displayed category. That is not a universal claim about every workflow or provider route.
Which model has the higher LiveBench score?
Claude Fable 5 Max Effort is listed at 83.0 Overall, while ox-alpha-max is listed at 69.2 in the same LiveBench snapshot.
Is Fable 5 worth the higher cost?
The answer depends on your workload, quality target, latency, provider pricing, and review process. LiveBench's cost-per-successful-task field is not an API price, so production cost must be measured separately.
Is Ox Alpha benchmark vs Fable 5 the same as an API comparison?
No. The benchmark table compares public leaderboard records. An API comparison also needs matched routes, prompts, budgets, tools, dates, failure handling, and actual provider billing.
