Pro 0813 vs Fable 5
Tied on TB2.1, Fable still ahead on DeepSWE
On DeepSeek's own 0813 table, Terminal-Bench 2.1 reads 87.9 vs 88.0 — essentially a tie, with the Fable 5 column labelled w/ fallback. Price is the real divide: $0.435/$0.87 against $10/$50.
Highlights
TB 2.1
Essentially tied. These are Terminal-Bench 2.1 numbers; Grok's launch table uses TB v3.0, a different scale that is not directly comparable.
DeepSWE
Fable 5 (w/ fallback) still leads the hard coding-agent row.
HLE w/ tools
Fable 53.3/63.0 vs Pro 42.7/60.0 (wo/w).
Output price
V4 Pro output is $0.87/M today; Claude Fable 5 lists officially at $10/M input and $50/M output.
The matchup
This is the search that asks if 0813 is a Fable substitute. On DeepSeek’s own grid it is a peer on terminal-bench and still behind on DeepSWE, Toolathlon and internal fullstack.
Why it is trending
The community used April's V4 Pro Preview as a punchline on Baba-is-bench. Those 29% figures belong to the Preview build; the 0813 release has no published score on that benchmark.

DeepSeek peak/off-peak. Still far under Fable-class API bills.
How to quote the HF grid
On the table
The table below uses only DeepSeek's same-source 0813 grid published on Hugging Face, where the Fable 5 column is labelled w/ fallback. Cybergym 83.3 vs 83.1 is a fair tie.
Off the table
Three common misreadings: treating blog rumours as Fable 5's official price, pinning the Preview build's low scores on 0813, and putting Terminal-Bench 2.1 and v3.0 numbers in the same table.
Who should pick what
Need Fable judgment / brand / Claude stack
Stay on Fable 5 or Opus 5. The HF grid still gives Fable the harder agent rows.
Need open 1.7T and a 30–50× cheaper token bill
Pro 0813. Self-host or official API. Pair with Flash 0731 for volume.
How to use it
Same 1M context. Different products: one MIT checkpoint, one closed premium model.
On QCode
QCode currently lists both deepseek-v4-pro and claude-fable-5 on /models. QCode is a multi-model access layer and is not affiliated with either vendor.
FAQ
Is 0813 equal to Fable 5?
No. Tied on TB2.1; behind on DeepSWE and several agent rows.
Why w/ fallback on Fable?
That is how DeepSeek labeled the column. Omitting it overstates Fable or understates Pro.
Can I self-host the Fable side?
No. Only Pro 0813 is MIT.
Flash 0731 vs this matchup?
Flash is cheaper and close on some agent rows; 0813 is the Pro-side of the Fable question.
Old 4.8 Opus in the HF table?
DeepSeek included Opus-4.8 as a published reference, not as this page’s hero opponent.
Peak price kill the gap?
No. Even peak Pro output $3.96 is not Fable-class billing.

Peer on terminal, not a Fable clone
Keep Fable for the last 5% of hard agent work; use 0813 when the bill is the product.
