Use Case Recommendations
Best for: Claude Fable 5
Anthropic's most capable publicly available model, released June 9, 2026. Claude Fable 5 is state-of-the-art on nearly all tested benchmarks — software engineering, knowledge work, vision, scientific research, and long-horizon agentic tasks. Stripe reported Fable 5 compressed months of engineering into days, completing a codebase-wide Ruby migration in a single day that would have taken a whole team two months by hand. Priced at $10/M input and $50/M output tokens. Note: access was temporarily suspended June 12–present due to a US government export control directive.
Ideal use cases:
- •Teams or individuals who need state-of-the-art on nearly all public benchmarks at launch
- •Teams or individuals who need highest score on cognition frontiercode among frontier models (even at medium effort)
- •Teams or individuals who need top score on hebbia finance benchmark for senior-level financial reasoning
- •Teams or individuals who need vision: rebuild web apps from screenshots; extract numbers from dense scientific figures
- •Anyone focused on anthropic workflows
- •Anyone focused on claude workflows
Best for: Defapi
Defapi is a single-endpoint gateway across image, video, text and music models from multiple vendors, sold on credits rather than a subscription. The catalogue is the product: frontier text models from Anthropic, OpenAI and Google sit alongside image and video generators, each listed with its own per-million-token or per-request rate on the model card so you can compare before you route, and the site publishes a short capability note for each — which ones are cheap and fast, which carry long context, which are built for agent workflows. Access is by API key against a shared balance, with usage history and billing records in the dashboard, so a team running several model families does not have to maintain a separate account, key and invoice per vendor. The commercial model is deliberately simple and unusually honest about its own limits: you top up a balance, credits are consumed at the actual model rate as requests land, there is no monthly commitment and — the site says so plainly on the pricing page — no bonus credits are currently included, so the top-up packages are one dollar of credit per dollar spent. That transparency is worth noting in a category where the margin is usually buried. The operator is KeyStorm LLC, registered in Wyoming. Points to weigh: rates vary by provider, input, output and feature, so the site tells you to check each model card before high-volume use, and community support runs through Telegram rather than a ticket queue.
Ideal use cases:
- •Teams or individuals who need one api key and one balance across text, image, video and music models from several vendors
- •Teams or individuals who need per-model rates published on the model card before you route to it
- •Teams or individuals who need no subscription — credits are consumed at actual usage
- •Teams or individuals who need usage history and billing records in the dashboard
- •Anyone focused on llm-api workflows
- •Anyone focused on model-gateway workflows
