# LLM Council

You can query multiple LLM models with the same prompt directly from CodeAct
using the built-in `llm_query()` and `llm_query_batched()` functions. Both
accept a `model=` (or `models=`) keyword that overrides the configured model
for that call.

Per-request model override support varies by backend:

| Backend            | Honors `model=`? | Cross-vendor routing? |
|--------------------|------------------|-----------------------|
| NEAR AI            | Yes              | Yes (aggregator — hosts models from many vendors) |
| Anthropic OAuth    | Yes              | No (Anthropic models only) |
| GitHub Copilot     | Yes              | No (Copilot-exposed models only) |
| Bedrock            | **No**           | — (model fixed at construction) |
| OpenAI / Ollama / Tinfoil via rig | No (silent fallback with warning log) | — |

A genuine *cross-vendor* council (Anthropic + Google + OpenAI in one batch)
therefore only works on an aggregator backend like NEAR AI. On single-vendor
backends, use a lineup of models available within that vendor.

## When to use a council

- The user wants diverse perspectives on a question or analysis
- Cross-referencing answers to increase confidence
- Comparing reasoning approaches across models
- Getting a "second opinion" from different AI models
- Research or evaluation tasks that benefit from multiple viewpoints

## Default council line-up

Check the configured backend first (e.g. from `LLM_BACKEND` or the user's
settings) before picking a lineup. Unless the user requests specific models,
use the matching default below.

**NEAR AI (aggregator — default council):**
```python
COUNCIL = [
    "anthropic/claude-opus-4-6",
    "google/gemini-3-pro",
    "zai-org/GLM-latest",
    "openai/gpt-5.4",
]
```
This 4-model lineup spans the major frontier providers and reasoning styles.
It **only works on NEAR AI** (or another aggregator) — the prefixed model
names route inside NEAR AI to the respective vendors.

**Anthropic OAuth** (Anthropic-only, no cross-vendor routing):
```python
COUNCIL = [
    "claude-opus-4-6",
    "claude-sonnet-4-6",
    "claude-haiku-4-5",
]
```
Use different Anthropic tiers for diversity of reasoning depth vs. speed.

**GitHub Copilot** (whatever Copilot exposes):
```python
COUNCIL = ["gpt-5.4", "claude-opus-4-6", "gemini-3-pro"]
```
Copilot's available models shift over time — call `llm_query` with the
user's configured default if you're unsure which are reachable.

**Bedrock / OpenAI / Ollama / Tinfoil:** per-request `model=` is not honored
by these backends. A council is not possible without switching backends —
tell the user and fall back to a single-model answer.

If the user names specific models, always use those instead of the defaults.

## API

### Single call with a model override
```python
answer = llm_query(
    prompt="What is X?",
    context="Optional background",     # optional
    model="anthropic/claude-opus-4-6", # optional per-call override
)
```

### Parallel council (same prompt, many models)
```python
COUNCIL = [
    "anthropic/claude-opus-4-6",
    "google/gemini-3-pro",
    "zai-org/GLM-latest",
    "openai/gpt-5.4",
]
responses = llm_query_batched(
    prompts=["What are the main risks of X?"] * len(COUNCIL),
    models=COUNCIL,                    # parallel array, length must match prompts
    context="Answer in 3-5 bullet points.",
)
# `responses` is a list of strings in the same order as `models`.
# If a specific model is unavailable, that slot returns "Error: ..." —
# the rest of the batch still completes.
```

### Single model applied to many prompts
```python
results = llm_query_batched(
    prompts=["Q1", "Q2", "Q3"],
    model="anthropic/claude-opus-4-6", # singular: applies to every prompt
)
```

### Mixing `models=` slots with `None`
A `None` slot inside `models=[...]` means "no override for this prompt" —
that call uses the configured default model. The singular `model=` kwarg
does NOT backfill `None` slots; it is only used when `models=` is omitted
entirely.

## After collecting responses

1. **Identify consensus** — note where models agree
2. **Flag disagreements** — analyze where they diverge and why
3. **Synthesize** — produce a unified answer that accounts for all perspectives
4. **Cite** — reference which model contributed each insight

## Full example

```repl
COUNCIL = [
    "anthropic/claude-opus-4-6",
    "google/gemini-3-pro",
    "zai-org/GLM-latest",
    "openai/gpt-5.4",
]
question = "What are the main risks of relying on a single LLM provider?"

responses = llm_query_batched(
    prompts=[question] * len(COUNCIL),
    models=COUNCIL,
    context="Answer concisely in 3-5 bullet points.",
)

# Build a synthesis prompt
labelled = "\n\n---\n\n".join(
    f"**{model}**:\n{resp}" for model, resp in zip(COUNCIL, responses)
)

synthesis = llm_query(
    prompt=f"Synthesize a balanced answer from these {len(COUNCIL)} expert opinions:\n\n{labelled}",
    context="Identify consensus, flag disagreements, and produce a unified answer.",
)

FINAL(synthesis)
```

## Notes

- `llm_query_batched()` runs all calls in parallel — total latency is roughly the slowest model.
- If `models=` is provided, it must be the same length as `prompts`.
- Use `model=` (singular) when you want one model applied to every prompt; use `models=` (plural list) for the council pattern.
- Errors from individual models (unavailable model, provider timeout, etc.) surface as `"Error: ..."` strings in the result list, so a single bad model does not fail the whole batch. Argument validation errors — wrong types, or `models`/`prompts` length mismatch — still raise exceptions.
