Claude Fable 5.2 Pricing: $8 Input, $40 Output per 1M Tokens
Claude Fable 5.2 is priced at $8 per 1M input tokens and $40 per 1M output tokens, a 20% cut from Fable 5.1's $10 and $50, with an optional fast mode at $16 and $80 for up to 2.5x faster generation.
Last updated: November 2026
Key takeaways
- Standard Fable 5.2 and Mythos 5.2 pricing: $8 input, $40 output per 1M tokens.
- Fast mode doubles the rate to $16 and $80 for up to 2.5x faster generation.
- Cache reads cost $0.20 per 1M and cache writes $10 (5-minute) or $16 (1-hour), per Latent Space's recap.
- Anthropic itself points to Opus 5.5 as the daily driver for most tasks, and Fable 5.2 for the hardest open-ended work.
- Per-token price is only half the story, so check cost per task before you switch.
What does Claude Fable 5.2 cost?
Anthropic announced Claude Fable 5.2 and Claude Mythos 5.2 on November 9, 2026, in its official launch post. Standard pricing for both is $8 per 1M input tokens and $40 per 1M output tokens. Output is 5x the input price.
Previous Fable 5.1 pricing was $10 and $50, which makes the new rate a 20% reduction, per Latent Space.
How does Fable 5.2 compare to other Claude models?
The table below uses Anthropic's official figures for Fable 5.2 and TrueFoundry's published table for the others; check the live provider page before budgeting.
| Model | Input $/1M | Output $/1M | Cache read $/1M | |---|---|---|---| | Fable 5.2 | $8 | $40 | $0.20 | | Fable 5.2 fast mode | $16 | $80 | not stated | | Fable 5.1 | $10 | $50 | $0.25 | | Opus 5.5 | $4 | $20 | $0.20 | | Sonnet 5.5 | $2 | $10 | $0.10 | | Haiku 5.5 (up to 100K prompt) | $0.10 | $0.50 | $0.01 |
Fable 5.2 costs exactly twice Opus 5.5 per token. For a request with 10,000 input and 1,000 output tokens, that is $0.12 on Fable 5.2 versus $0.06 on Opus 5.5 (illustrative). Our comparison of the previous generation is in Claude Fable 5 vs Opus 5 pricing.
Is Fable 5.2 worth 2x the price of Opus 5.5?
Anthropic's own guidance is that Fable and Mythos are for the most demanding open-ended technical work, and that Opus 5.5 is the recommended daily driver for most tasks. On its benchmark table, Fable 5.2 scores 49.1% on FrontierCode 2.0 (Xhigh) against 32.4% for Fable 5.1, but at High effort it is level with Opus 5.5 at Max effort (45.3% vs 45.5%). If your task already works on Opus 5.5, the 2x token rate buys little.
What is Fable 5.2 fast mode?
Fast mode generates output up to 2.5x faster at 2x the standard price, $16 input and $80 output per 1M tokens. It is available in Claude Code, the Claude Platform, Claude Models on Google Cloud and Microsoft Foundry. Pay it only where latency is the product, such as interactive coding or live agents.
What will Fable 5.2 cost for a real SaaS workload?
Say an agent product runs 20,000 tasks a month, each using 150,000 input tokens (mostly stable context) and 10,000 output tokens. That is 3B input tokens and 200M output tokens. Without caching: $24,000 of input plus $8,000 of output, or $32,000 a month.
Now say 90% of input is served from cache at $0.20 per 1M. Cached input costs 2.7B x $0.20 per 1M = $540, the remaining 0.3B uncached tokens cost $2,400, and output stays $8,000. The total is about $10,940 a month, before cache-write costs (all figures illustrative). Caching, not the headline rate, is the lever.

Frequently asked questions
How much does Claude Fable 5.2 cost per million tokens?
Standard pricing is $8 per 1M input tokens and $40 per 1M output tokens. Fast mode is $16 and $80.
Is Claude Fable 5.2 cheaper than Fable 5.1?
Per token, yes: it is 20% cheaper than Fable 5.1's $10 and $50. Per task, it can cost more because Fable 5.2 may use more tokens for self-checking.
What is the difference between Fable 5.2 and Mythos 5.2?
They are the same underlying model. Mythos 5.2 drops certain cyber and biology safeguards and is limited to vetted organizations in Anthropic's verification programs.
Should I use Fable 5.2 or Opus 5.5?
Use Opus 5.5 as the default, since it costs half as much per token. Move to Fable 5.2 only for the hardest open-ended technical tasks where the extra capability changes the outcome. The takeaway: Fable 5.2 is cheaper per token than Fable 5.1 but still twice Opus 5.5, so route only the hardest work to it. Model the split with the Calcaas LLM cost calculator.

Product UpdatesMeta Muse Ember Pricing: What $0.10 per 1M Input Tokens Means for Agents
Meta's Muse Ember lists at $0.10 per 1M input tokens, but no output price was published at launch, so the real cost of an agent step depends on tokens per task and the output rate, not the input line alone.

Product UpdatesClaude Opus 5's Price Didn't Change, But Your Cost-Per-Task Probably Just Dropped
Opus 5 launches at the same $5/$25 per million token price as its predecessor, but Anthropic's own benchmarks suggest it needs fewer tokens and fewer retries to hit the same result, which is the number that actually matters for your margins.
