   Anthropic ships Claude Opus 5 — near-Fable intelligence at half the price

   Four days after the split took effect, Anthropic launches Claude Opus 5 at $5 input / $25 output per million tokens — unchanged from Opus 4.8, and exactly half of Fable 5's rate. The company positions it as delivering nearly all of Fable 5's intelligence; it becomes the default model on Max and the strongest model included with Pro. Anthropic also says Opus 5 runs with roughly 85% fewer safety-classifier interventions than Fable 5 and is exempt from the 30-day retention policy. For Pro users weighing the one-time $100 Fable credit, this resets the question.

   Moonshot ships Kimi K3: near-Sol coding scores, open weights, $3/$15

   Moonshot AI releases Kimi K3, a 2.8-trillion-parameter MoE with a 1M-token context and native vision. Self-reported Terminal-Bench 2.1: 88.3 — just under GPT-5.6 Sol's 88.8 and above Fable 5's published score — at $3/$15 per million tokens with a 90% cache discount. Open weights are promised by July 27. Another serious budget seat in the model mix as Fable 5's split takes effect.

   Permanent: Fable 5 stays on Max and Team Premium — Pro moves to credits with $100 included

   One day before the window was due to close, Anthropic announces the lasting arrangement: from July 20, Fable 5 remains included on Max and Team Premium plans at up to 50% of weekly limits — described as permanent, not another extension — while Pro and Team Standard move to usage credits at $10 input / $50 output per million tokens, cushioned by a one-time $100 credit. The reversal lands amid open price pressure from GPT-5.6 Sol at half Fable 5's token rate.

   Extended again: Fable 5 stays in paid plans through July 19

   In a late-night post from its official @claudeai account — with the promotional-access support article updated to match — Anthropic extends the plan-included window a second time, now through July 19. Terms unchanged: Pro, Max, Team, and select Enterprise plans, up to 50% of weekly usage limits, applying automatically. After July 19, Fable 5 bills through usage credits at $10 input / $50 output per million tokens. Anthropic continues to say the credits move isn't permanent.

   xAI ships Grok 4.5 — a cheaper coding model lands in the switching week

   xAI releases Grok 4.5, its first model built for coding and agentic work, priced at $2 input / $6 output per million tokens — well under Fable 5's $10/$50 usage-credit rate. Elon Musk calls it "Opus-class"; independent testing is more measured. Artificial Analysis places it fourth on its Intelligence Index (54), behind Fable 5 (60), Opus 4.8 (56), and GPT-5.5 (55); its Terminal-Bench 2.1 score of 83.3 (xAI's own number) sits just under Fable 5's 84.3. A genuine low-cost option to weigh as Fable 5's plan window nears its close (since extended to July 19).
