All other OpenAI SDK calls work unchanged. - --- -## How Routing Works +## Parallel Ensemble — Best Answer, Any Provider -For every request, A3M Router scores complexity across five signals: +Need the best answer regardless of cost? Call multiple providers in parallel: -| Signal | What it detects | -|--------|----------------| -| **Domain** | Legal, medical, code, finance, ML keywords | -| **Task type** | Code generation, translation, analysis, creative | -| **Query structure** | Clause count, length, qualifier words | -| **Verb intensity** | "design/architect" → complex, "what/who" → simple | -| **Multi-step** | Explicit step markers (first...then, step 1/2/3) | - -The combined score maps to a tier (free → cheap → mid → premium). Within that tier, A3M picks the cheapest available provider with a passing health score. +```python +from a3m.router import A3MRouter -This is the same approach other routing systems use — the key differences between implementations are: +router = A3MRouter( + model="auto", + parallel_ensemble=3, # ← Call 3 providers simultaneously +) -- **Signal weights** — how much each dimension contributes -- **Provider tiers** — which models live in which tier -- **Health scoring** — how failures and latency affect provider selection -- **Fallback behavior** — what happens when the preferred provider is down +result = router.route( + messages=[{"role": "user", "content": "Explain quantum entanglement"}], + ensemble_timeout_ms=10000, +) -A3M stores no training data, requires no GPU, and routes in ~140ms overhead. +# result.content — winning response +# result.provider — which provider won +# result.scores — quality scores per provider +# result.all_results — all responses for comparison +``` ---- +**Real-world example:** +```python +# Call Groq (fast/cheap) + OpenAI (quality) + DeepSeek (cost-effective) in parallel +ensemble_result = router.route( + messages=[{"role": "user", "content": prompt}], + ensemble_config={ + "providers": ["groq", "openai", "deepseek"], + "timeout_ms": 15000, + "score_weights": {"relevance": 0.4, "conciseness": 0.3, "accuracy": 0.3} + } +) -## Why Not Just Use LiteLLM? +print(f"Best answer from: {ensemble_result.provider}") +print(f"Response: {ensemble_result.content}") +print(f"All scores: {ensemble_result.scores}") +``` -LiteLLM is the dominant open-source AI gateway (54K stars). It handles unified API access well. A3M Router adds three capabilities LiteLLM doesn't have built-in: +--- -### 1. Heuristic Routing -LiteLLM routes by model name or requires you to specify which model to call. A3M's `model="auto"` mode analyzes the query content and picks the cheapest capable provider automatically. This is useful when you want cost efficiency without writing routing logic. +## Multi-Agent Systems — CrewAI Example -### 2. Biology-Inspired Provider Selection -A3M applies established ecological and evolutionary theory to routing decisions: +Powerful for multi-agent systems where different agents need different model capabilities: -**EXP3 Diversity Weighting** — Negative frequency-dependent selection prevents any single provider from dominating traffic. Providers above their fair share (1/n of total) receive a penalty proportional to their deviation. This mirrors how ecological niches prevent competitive exclusion — no species dominates when resource competition is symmetric. +```python +from crewai import Agent, Task, Crew +from crewai.llms import A3MCompletion + +# Research agent — needs factual accuracy +researcher = Agent( + role="Research Analyst", + goal="Find accurate information", + backstory="Expert researcher", + llm=A3MCompletion(model="auto", temperature=0.3), +) -**Charnov MVT Rate-Limit Rotation** — When a provider's rate-limit window becomes depleted, A3M uses the Marginal Value Theorem (Charnov 1976) to decide the optimal time to switch. It leaves when the marginal remaining rate falls below the average rate including switch cost — the same logic that explains when animals should leave a depleting food patch. +# Writer agent — needs creativity +writer = Agent( + role="Content Writer", + goal="Create engaging content", + backstory="Creative writer", + llm=A3MCompletion(model="auto", temperature=0.9), +) -**ODT Shadow Verification** — For high-stakes queries, A3M can probabilistically sample a shadow provider to verify the primary's answer. The sampling probability follows Optimal Defense Theory: tissue value (query stakes) and attack probability (risk profile) scale verification effort proportionally. This is how plants allocate defensive compounds — expensive defenses go to valuable tissues. +# Critic agent — needs balance +critic = Agent( + role="Quality Critic", + goal="Ensure quality", + backstory="Detail editor", + llm=A3MCompletion(model="auto", temperature=0.5), +) -### 3. Parallel Ensemble Execution -Sometimes you want the best answer regardless of cost. A3M can call multiple providers in parallel, score each response, and return the best one — with full provenance of which provider won and why. +# Tasks with expected outputs +research_task = Task( + description="Research AI trends", + expected_output="Detailed report with citations", + agent=researcher, +) -```typescript -import { executeEnsemble } from 'adaptive-memory-multi-model-router/ensemble'; +crew = Crew( + agents=[researcher, writer, critic], + tasks=[research_task], + process="hierarchical", + manager_llm=A3MCompletion(model="auto"), +) -const result = await executeEnsemble( - "Explain how vector databases work", - systemPrompt, - context, - { groq: callGroq, openai: callOpenAI, nvidia: callNvidia }, - { providers: ['groq', 'openai', 'nvidia'], timeoutMs: 30000 } -); -// result.winner — which provider gave the best response -// result.scores — per-provider quality scores -// result.allResults — all responses preserved +result = crew.kickoff() ``` -### What A3M doesn't do (LiteLLM does) -- Virtual keys, spend limits per team/user -- Admin dashboard, UI -- OAuth/SSO integration -- LangChain/LlamaIndex first-class integrations -- Enterprise SLA and support contracts - -A3M is a routing engine. LiteLLM is an enterprise platform. Use the right tool for your stage. - -### OpenAI-Compatible API -The API format is OpenAI-compatible — same `/v1/chat/completions` endpoints, same request/response shapes — so any OpenAI-compatible SDK or proxy tool works with A3M without code changes. This is useful for switching providers behind an existing integration or for tooling that only supports the OpenAI format. - --- -## Architecture +## LangChain + LlamaIndex Adapters -``` -Request → Guardrails → Cache → Router → Provider → Response - ↓ - Cost tracking - Metrics -``` +Use A3M Router as a drop-in replacement: -**Guardrails** — Runs before any provider call: prompt injection detection, PII detection, content filtering. Rejects or sanitizes dangerous input. +```python +# LangChain +from a3m_adapter import A3MLangChainAdapter -**Semantic Cache** — Optional. Uses embedding similarity to return cached responses for repeated queries. Cache hit = instant response, zero provider cost. +llm = A3MLangChainAdapter( + model="auto", + temperature=0.7, + parallel_ensemble=2 +) -**Router** — Scores the query, selects tier, picks the cheapest healthy provider in that tier. Model quality scores update online via exponential moving average after each real call — no retraining. Three biologically-inspired mechanisms run inside the router: -- **EXP3 diversity weighting** — negative frequency-dependent selection prevents any provider from dominating traffic (no competitive exclusion) -- **Charnov MVT rate-limit rotation** — optimal departure time from depleting rate-limit windows -- **ODT shadow sampler** — probabilistically verifies high-stakes queries proportional to query value (tissue value) and risk (attack probability) +# Works with any LangChain chain +from langchain import chain +result = llm.invoke("What is retrieval-augmented generation?") -**Ensemble** — Optional.
