Best model for coding
ContestedClaude Fable 5.
As of · Reviewed Jul 17, 2026
Under review: Jul 19 - Fable's promotional subscription access ends
- Runner-up
- GPT-5.6 Sol - benchmark-competitive, but one week of real-world use so far
- Budget pick
- Claude Sonnet 5 - intro $2/$10 per 1M tokens through Aug 31 (as of Jul 17)
Full verdict
Why
Fable 5 performs well on multi-file refactors and long-horizon changes that require consistent architectural context. During its 19-day export-control suspension, we used Opus 4.8 and restored Fable as the coding pick when access returned on July 1. GPT-5.6 Sol has competitive agentic-coding results and a four-agent ultra mode, but it has not yet accumulated a month of daily production use. Fable costs $10/$50 per 1M tokens, so Sonnet 5 remains the lower-cost option.
The receipts
- Vellum LLM Leaderboard - independent benchmark standings, verified Jul 17
- Artificial Analysis - price and speed comparisons across the tier
- Matt's hands-on tests - Fable 5 daily-driver coverage since Jun 9
- Anthropic - pricing and availability, as of Jul 17
What would change our mind
- If Sol's real-world reliability matches its benchmark numbers after a month of daily use, this flips.
- If the July 19 promo cliff puts Fable out of subscription reach for most readers, the budget pick becomes the practical ruling.
Ruling history
- Jul 1, 2026Re-flipped to Fable 5 the day it was restored (US export controls lifted Jun 30).
- Jun 12, 2026Reverted to Opus 4.8 when a US export-control order pulled Fable 5 offline worldwide.
- Jun 10, 2026Flipped from Opus 4.8 to Fable 5 after initial testing favored Fable on long-horizon coding tasks.
