Claude Fable 5 in context
On a typical 70% input / 30% output mix, Claude Fable 5 blends to $22.00 per million tokens. That puts it above 94% of the 32 models tracked here, and 6 other models in the same flagship tier undercut it. Tier is a capability label, not a price band — the spread inside one tier is often wider than the gap between tiers, which is why picking by tier alone tends to overspend.
Input runs $10.00 per million and output $50.00 — a 5.0x ratio. That ratio matters more than either number on its own: a summarisation or classification workload reads far more than it writes and will track the input price, while a code-generation or long-form writing workload inverts that and will track the output price. Compare models on the ratio your own traffic actually has, not on the input price alone.
The benchmark profile is unusually flat — coding leads at 100/100 but only 4 points separate the strongest category from the weakest. That makes Claude Fable 5 a safe default for mixed workloads where you cannot predict in advance which capability a request will lean on, and a poor choice if you need a specialist.
The context window is 1M tokens and the throughput score is 55/100. Context only earns its keep if you fill it, and filling it is also what makes a request expensive — a large window is an option, not a discount. For a flagship-tier model, judge the speed score against what you are doing: it decides everything for interactive chat and almost nothing for overnight batch work.
Nothing cheaper in the table matches Claude Fable 5 on combined coding and reasoning, so its $22.00 blended price is buying capability you cannot get for less right now. That is the case for paying it — and it is worth re-checking, because this is exactly the position that a new release takes away.
The closest comparison is Claude Opus 4.6 from Anthropic, at $11.00 per million against $22.00. 0 models in this tier score higher on combined coding and reasoning, which is the useful framing: the question is rarely whether a model is good, it is whether it is the cheapest thing that is good enough for the specific work you are sending it.
What it costs in production
At 10M + 2M tokens a month — a realistic mid-size production workload — Claude Fable 5 runs about $200.00. Routing the latency-tolerant share through the batch API at 50% off would bring that to roughly $100.00, which is usually a bigger saving than switching models.
Price History
No price changes since launch
Strengths
- Highest measured intelligence of any widely released model
- Thinking is always on — no budget to tune
- Sustains hours-long autonomous agentic runs
- 1M context at a flat rate, no long-context premium
Avoid For
- Anything routine — the cheaper tiers match it on easy tasks
- Latency-sensitive paths (single turns can run minutes)
- Workloads that cannot meet 30-day data retention
