RPCS-1
Built on RPCS-1 receiver dynamics · Pred-09-5 validated

Configure AI agents that don't oscillate, overload, or freeze.

Describe your agent's task and environment. Get exact temperature, context strategy, and model recommendation — derived from your agent's operating conditions, not guesswork.

Start with a filled example if you just want to see whether the framework clicks. No account, email, or payment required.

before / after

Same agent. Different operating regime.

Without tuning, defaults can loop under pressure. With RPCS-1, the same workload gets bounded thresholds, cleaner tool use, and a stable path to action.

Unconfigured agent

High stakes, dynamic inputs, guessed defaults

competitive context

RPCS-1 does not replace your stack. It tells the stack how to behave.

Most AI engineering tools help you build, trace, evaluate, or iterate. RPCS-1 sits one layer lower: it converts operating conditions into a receiver profile and runtime posture.

CategoryAgent frameworks
ExamplesLangChain, CrewAI, AutoGen
What they optimizeBuild workflows, tools, memory, and agent orchestration.
Common gapStill leaves teams guessing the operating regime and parameter profile.
RPCS-1 layerAdds a deterministic tuning layer for entropy, stakes, context, and commitment.
CategoryObservability
ExamplesLangSmith, Langfuse, Helicone
What they optimizeTrace runs, monitor latency/cost, inspect failures, and debug production behavior.
Common gapGreat at showing what happened after the run; less focused on pre-run regime selection.
RPCS-1 layerRecommends the behavioral settings that reduce oscillation, overload, and freeze before launch.
CategoryEvals and experiments
ExamplesBraintrust, promptfoo, custom evals
What they optimizeScore prompts, compare variants, and measure model or workflow quality.
Common gapTeams still need a theory for which knobs to change when an eval fails.
RPCS-1 layerMaps failure modes to concrete parameter changes and explains why those changes fit.
CategoryPrompt iteration
ExamplesPrompt libraries, playgrounds, manual tuning
What they optimizeImprove instructions, examples, and output shape.
Common gapPrompt edits can hide structural instability instead of fixing it.
RPCS-1 layerTunes the receiver profile under the prompt: TI, SG, FT, UE, and AR.

Benchmark data is synthetic simulation output. Use it as directional evidence, then validate against your own production traces.

The problem every agent builder has

You ship an agent. It works in testing. In production it starts failing in one of three structural ways — and you have no framework for diagnosing why.

Oscillation

Agent revisits the same tool calls, refuses to commit. High TI + high SG in a fast-changing environment.

Lower SG, shorten context window (TI ↓)

Overload

Agent acts on insufficient information, hallucinates tool calls. High SG + low FT + short integration.

Raise FT, lower SG, add retry strategy

Freeze

Agent hedges endlessly, never takes action. Low UE + high FT — stuck in the filter.

Lower FT, raise UE, adjust commitment style

Five primitives. One structural framework.

Every recommendation is driven by five receiver primitives from RPCS-1, each mapping to a specific LLM parameter. All outputs are deterministic and traceable — no black-box recommendations.

TI

Temporal Integration

How much history to integrate. Maps to context window strategy and max_tokens.

SG

Signal Gain

How strongly to amplify signals. Maps inversely to temperature.

FT

Filtering Threshold

How conservatively to gate action. Drives tool use strategy.

UE

Update Elasticity

How readily to revise the model. Sets retry and grounding strategy.

AR

Ambiguity Resolution

How aggressively to commit when uncertain.

The Matching Principle: TI ≈ 1 / H

Agents in high-entropy environments need short attention windows. Agents in stable environments benefit from long integration. This single principle drives the core of every parameter recommendation.
