Today we are rolling out v2 of the Beast model lineup. Beast Nano, Beast Mini, and Beast Max all move to v2, with a wave of improvements across the API, tool calling, vision, and chat. Here is what is new.
Prompt caching, end to end
Beast now fully supports prompt caching across both the Chat Completions and Responses APIs. Repeated context such as long system prompts, documents, and ongoing conversation history is cached automatically, so follow-up requests come back faster. Cached and uncached tokens are itemized clearly in your usage, and the savings are reflected directly in your billing.
Cached input is billed at 90% off the standard input rate, and there is no extra cost to write to the cache. Per 1M tokens:
- Beast Nano: $8 input, $0.80 cached input, $10 output
- Beast Mini: $12 input, $1.20 cached input, $15 output
- Beast Max: $70 input, $7 cached input, $90 output
More reliable tool and function calling
We improved reliability for function calling, including parallel tool calls, so agentic and multi-step workflows run more smoothly across both API endpoints.
Better image understanding
Beast now makes fuller use of the images you provide when reasoning about a request, improving response quality on visual and multimodal tasks.
Stronger, safer file and image handling
Fetching images and documents from URLs is now more robust and secure, with automatic retries on transient errors and smarter caching to avoid re-downloading the same content.
Cleaner API responses
We tidied up response and error payloads by removing internal metadata and headers, so what you receive is clearer and more predictable to build against.
Chat improvements
- A new per-message toggle to switch between the formatted and raw view of any Beast reply.
- Richer, more descriptive live progress updates while Beast is working through a request.
Ongoing quality and accuracy tuning
A range of refinements keep responses consistent, well-calibrated, and accurate, including more precise usage and cost reporting.
Every change above ships today across Beast Nano, Beast Mini, and Beast Max v2. See the full model specs and pricing, or try v2 now on the Portal.
