NEWS FLASH: GM (SN28) Undercuts Anthropic, Offers 8.1% Discount on Fable 5.1

Fable 5.1 is now serving on GM (SN28) at $9.17 per million input tokens, $45.84 per million output tokens, and $0.23 per million on prompt cache reads. The price sits exactly 8.1% below what the same model costs through Anthropic directly.

Anthropic built Fable 5.1 as an upgrade over Fable 5, targeting coding agents, multi-step workflows, code generation from visual inputs, and financial or analytical work. Fable 5 remains live on GM at 64% off list pricing for anyone whose workflows fit the earlier model comfortably.

What Fable 5.1 Improves

The newer release raises the ceiling on workloads Fable 5 already handled competently across most benchmarks.

1. Coding agents get sharper output on complex multi-file tasks: Longer sessions holding cross-repository context benefit from improved reasoning across the whole codebase.

2. Multi-step workflows reach higher completion rates: Chained operations spanning research, synthesis, and delivery survive more turns without losing thread coherence.

3. Code generation from visual inputs improves noticeably: Screenshots, diagrams, and design mocks translate into working code with fewer manual corrections afterward.

4. Financial and analytical work sees quality gains: Numerical reasoning, spreadsheet analysis, and financial modeling all benefit from the raised ceiling.

Every improvement targets a workload where marginal quality gains translate into meaningful productivity differences for paying users.

Pricing Side by Side

The 8.1% discount applies uniformly across every pricing dimension the model exposes.

Same model, same output quality, 8.1% less on every line item across the invoice.

Two Models, One Discount Philosophy

GM (SN28) keeps positioning itself as the pricing layer sitting one step below every centralized inference provider on identical models.

Fable 5.1 arriving at 8.1% off mirrors the same discount GM applied when Fable 5 originally launched on the network.

Users pay less for the same output because miner competition beneath GM keeps supply costs honest rather than concentrating margin inside one corporate provider.
