About the model
This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.
DeepSeek V3 Fast is a named hosted text profile in the DeepSeek V3 family. The published entry lists a 32,000-token context and a completion allowance of 32,000 tokens. These are distinct budgets: a large response allowance does not make the entire working context available for both input and response separately.
Define a focused text artifact
Supply the source material and state the result to produce. A summary can preserve the facts and decisions needed by a particular audience. A comparison can apply explicit criteria to labelled passages. A revision can change named parts of an existing text while retaining the details the task requires.
Ask for an answer of suitable length and keep source identifiers where the result needs to be checked against the input. A later turn can examine one finding or provide a correction to the source.
Keep the Fast profile distinct
Organize the relevant input and response within the active working context. Preserve the exact Fast identity with the prompt and returned artifact when comparing variants.
The profile’s name does not establish a particular latency improvement, fixed dated V3 checkpoint or inherited tool setting. Use the actual interface’s controls for the selected profile and judge the result through the requested text artifact.
Practical task
Turn meeting notes into decisions
Technical example in English
Turn meeting notes into decisions
Create a decision record from these notes: the team chose weekly reports over daily reports; Priya will draft the template; the delivery day is undecided; customers still receive immediate failure alerts. Separate agreed decisions, assigned work and open questions. Keep reporting cadence distinct from alert timing.Expected result
A compact decision record with decisions, owner/action and unresolved question sections.Check the result
Weekly reporting and immediate failure alerts remain separate, and no delivery weekday is invented.Ailoot Ultra · OpenAI Chat POST /v1/chat/completions DeepSeek-V3-Fast-ultra
