Anthropic released Claude Fable 5.2 on November 9, 2026 (Anthropic launch announcement). The Claude API model ID is claude-fable-5-2; Anthropic's platform release notes list a 1-million-token context window, a 128k-token maximum output, and adaptive thinking for the model (Anthropic, Claude Platform release notes).
Anthropic says Fable 5.2 can generate outputs up to 30% faster than Fable 5.1. Its model-selection guide recommends Opus 5.5 for most coding and knowledge work, and positions Fable for demanding technical projects that benefit from a longer-horizon model (Anthropic, Claude Fable and Mythos 5.2; Claude model-selection guide).
Choose a model by task
Anthropic's model guide gives teams a practical starting point: use Opus 5.5 for most day-to-day coding and knowledge work, then reach for Fable 5.2 when the task is unusually complex or requires sustained technical work. The guide says to adjust effort before moving models, and to reserve Fable for the hardest technical projects or long unattended runs (Claude model-selection guide).
API pricing and fast mode
Anthropic's Claude API pricing page lists these per-million-token rates for Fable 5.2. Fast mode is available for Messages API requests; Anthropic says it can generate up to 2.5 times more output tokens per second (Anthropic pricing; Anthropic platform release notes).
| API mode | Input per million tokens | Output per million tokens |
|---|---|---|
| Standard API pricing | $8 | $40 |
| Fast mode | $16 | $80 |
Fable 5.1's standard API rates were $10 per million input tokens and $50 per million output tokens. Anthropic lists Fable 5.2 at $8 and $40 per million, and describes those rates as lower than Fable 5.1. Fast mode has a higher per-token price, and Anthropic describes it as faster (Anthropic pricing; Anthropic platform release notes; Anthropic launch announcement).
Plan access and the launch offer
Anthropic says Fable 5.2 is available on all paid Claude plans, including Pro, Max, Ultra, Team, and Enterprise. Max and Ultra plans, premium Team seats, and premium seats on seat-based Enterprise plans include Fable usage within their plan limits. Pro and standard Team seats use usage credits. Standard seats on seat-based Enterprise plans can use Fable models with usage credits if their organization has enabled them. Usage-based Enterprise plans are billed at standard API rates (Claude Help Center, Fable models on your plan).
The launch offer is time-limited. Eligible Pro and standard Team seats receive Fable usage within their weekly plan limits through November 16, 2026 at 11:59 pm PT, up to 50% of the weekly limit, plus one Fable limit reset. Eligible Max, Ultra, premium Team, and premium legacy Enterprise seats receive one to three resets depending on subscription length. The offer has eligibility exclusions, so check Anthropic's current terms before relying on a reset (Claude Help Center, Fable 5.2 launch offers).
