JEV / SYSTEM ONE
Laya uses the shared model, state and questions interface. This service maps Noul to the Gateway’s boolean question, converts the returned probability to noul, and normalizes token usage. Choice and Score retain their structured answers, so the same recipes, evaluation datasets and API code work here.
SPAN / NOUL
Span-01 and Span-01 Lite accept only Noul behavior questions and require text or a specific input/output conversation object. General decision models also accept Choice and Score questions with text, JSON objects or arrays as state. Span-02 follows this broader decision contract and supports images in the shared decision playground.
Choice returns a named option and its probability distribution. Score returns a value on an ordered scale with probabilities. Noul returns the probability of a yes/no condition. Multiple questions share the same state.
Vercel lists an 8,192-token context. This service applies the shared Laya limits: text or JSON state, up to 8 questions, 32 KiB for text plus questions, 2–100 Choice options and 2–10 Score levels. The context budget also applies. The 100-option live check was performed on convaiinnovations/laya, not this dedicated Free entry.
This page uses the dedicated convaiinnovations/laya-free entry on Vercel AI Gateway. It shares the Laya request adapter and platform limits. Provider routing and upstream pricing may change.
Laya Free has a 0-credit per-token rate. Web, API and evaluation charge the platform minimum of 1 credit ($0.0001) per successful request; output adds no charge and failed calls release the reservation. Vercel currently lists free input and output; this platform price is a separate service charge.
max(1, ceil(input_tokens × 0 / 1,000,000))
A successful request with 1,000 input tokens costs 1 credit; 5,000 input tokens cost 1 credits. Output tokens add no charge. Failed calls release the credit reservation.
Checked October 19, 2026 against the official Vercel model listing: 8,192-token context and free input/output. Local regression tests cover routing and answer normalization; no live request or accuracy benchmark is claimed for this entry.
The Jev workbench below starts with this model selected. Try a recipe, edit the state and questions, or export API code. This page stores its browser draft separately from other model pages and the main playground.
What do you want to decide?
Choose a task to load its input and rules. Loading examples uses no credits.
Laya supports Choice, Score and Noul through Vercel AI Gateway. Context: 8,192 tokens. Choice: 2–100 options. Every successful web, API or evaluation request costs 1 credit; output adds no charge.
We reserve this budget before the model runs, then charge actual usage and return the difference. Failed calls are refunded.
New account? Receive 100 credits once. Short requests typically use 1 credit; longer inputs can use more.

Static illustration of the output format. Values are not a live model response or a measure of accuracy.
Capture A, change the model or questions in the workbench, then capture B. Both versions use identical states.
Capture A from the current workbench model and rules. Change the model or questions, then capture B. Import up to 25 labeled cases and compare both versions. The dataset state replaces each captured state.
This simulates a policy, not accuracy. Noul uses max(P(yes), P(no)); Choice and Score use your selected signal. Validate thresholds on labeled cases.
Total budget across both versions and all cases. Each request reserves its own allowance, then settles actual usage and refunds the remainder. Stopping preserves charges for completed requests.
New account? Receive 100 credits once. Short requests typically use 1 credit; longer inputs can use more.
Each successful comparison request uses credits. Review the total budget before starting. Requests run sequentially; stopping keeps charges for completed requests. Export includes rules, cases, results and errors. Closing this page stops the comparison.
Send model, state, and questions to Decisions API's /v1/systemone endpoint with an API key created here. Set model to convaiinnovations/laya-free; answers are in data.result.answers and token usage is in data.result.usage.
