DeepSeek V4 ProDeep Reasoning with Logprobs
DeepSeek V4 Pro offers thinking toggles, high or max reasoning effort, logprobs evaluation signals, and production sampling for demanding analytical workloads.
At a Glance
V4 Pro Reasoning Stack
Analytical depth with evaluation hooks.
High or Max Effort
Dial reasoning between high and max for multi-step proofs and hard analysis.
Thinking Toggle
Enable or disable deep thinking per request depending on task complexity.
Logprob Evaluation
logprobs and top_logprobs expose token probability signals for confidence scoring.
Production Sampling
Temperature, top-p, max tokens, and stop sequences for controlled outputs.
How It Works
Deep analysis in four steps.
Set Thinking & Effort
Enable thinking and choose high or max depth.
Stream or Wait
Stream for long analyses; single-shot for batch evals.
Collect Logprobs
Use probability signals for confidence scoring.
Sample Responsibly
Tune temperature and top-p for tone control.
V4 Pro Domains
Where analytical depth is the product.
Formal Reasoning
Max effort for proofs and multi-hop analysis.
Eval Pipelines
Logprobs for confidence and regression tests.
Research Synthesis
High effort for literature and market synthesis.
Agent Decisions
Reasoned tool choice with probability signals.
Prompt Tips
