Fable 5's 6% first-month token share points to corporate AI price ceiling
This digest was compiled by AI from multiple sources — links to the originals are below.
Ramp spending data shows Anthropic's Fable 5 accounted for only 6 percent of tokens purchased from Anthropic in its first month after launch, and 11.4 percent of spending on Anthropic models. OpenAI's GPT-5.6 Sol captured 25 percent of tokens and 23 percent of OpenAI spending, while Fable 5 generated about 75 percent of GPT-5.6 Sol's model revenue despite costing roughly twice as much per token. The gap points to a ceiling on corporate willingness to pay for frontier AI, even as overall U.S. subscriptions to Anthropic and OpenAI expanded in July.
First-Month Adoption
Ramp's proprietary token spend management data, which skews toward technology companies, shows U.S. firms bought only 6 percent of Anthropic tokens from Fable 5 in its first month. Fable 5 accounted for 11.4 percent of spending on Anthropic models. OpenAI's GPT-5.6 Sol reached 25 percent of tokens and 23 percent of spending at OpenAI, while Fable 5 generated roughly 75 percent of GPT-5.6 Sol's model revenue despite a per-token price about twice as high.
Price and ROI Limits
Ramp economist Ara Kharazian ties Fable 5's slow uptake to cost: the model lists about $10 per million input tokens and $50 per million output tokens, roughly double GPT-5.6 Sol or other Anthropic flagship models. Kharazian sees the gap as a new ceiling on what companies will spend on AI and argues the extra performance is not worth the cost. The picture is more complicated: Fable 5's performance edge may be negligible in many daily work tasks, and companies lack a clear method for calculating AI return on investment across model generations. Genuinely more capable models could still command higher prices, but willingness to pay remains limited while measured value stays abstract.
Provider Adoption Slows
In July, 43.5 percent of U.S. companies paid for Anthropic subscriptions or tokens, up 1.1 percentage points from the previous month. OpenAI reached 39.7 percent, rising only 0.23 percentage points and lagging overall AI adoption growth. xAI recorded its fastest increase since July 2025, up 0.94 percentage points to 4 percent. Although new customers continue to sign up with U.S. model providers, advanced users whose spending OpenAI and Anthropic increasingly depend on are shifting toward open-source models.
What's Next
Ramp's next monthly token-spend release will show whether Fable 5's share expands beyond its launch-month sample. It remains unclear whether Anthropic will cut Fable 5's per-token pricing or whether enterprises will pay current rates for frontier-model improvements without clearer ROI measures.
