## Which one, for what

### Pipecat (B)

Good for: Python teams that want to own a voice agent's pipeline, pick each speech and model provider, and host it themselves or on Pipecat Cloud.

Ahead on:
- Reliability, 72 against 53
- Schema & documentation, 90 against 72
- Agent ergonomics, 72 against 61
- Payments & pricing, 60 against 40
- Maintenance & community, 87 against 58
- Transparency & trust, 81 against 56

Also in its favour:
- No key needed to call it
- Open source

Watch for: No tool-approval or confirmation step, and no prompt-injection guidance, for tools that act on a caller's speech

### Pipecat PhoneLLM (C)

Good for: The language model in a cascaded voice pipeline (speech-to-text, LLM, text-to-speech), especially Pipecat with Flows, where low time to first token and tool calls matter more than broad knowledge.

Ahead on:
- Security & auth, 66 against 57

Also in its favour:
- A hosted endpoint, with nothing to install
- No incidents deducted, where Pipecat loses 4 points for them

Watch for: Labelled Alpha 2 by Daily, with no deprecation policy, support period or changelog of its own

## Verdicts

**Pipecat.** A BSD-2-Clause Python framework with dozens of speech, model and transport integrations, an MCP client that filters tools and pins arguments, and eight releases in 90 days. It has no tool-approval step, and 1.12.0 can send OPENAI_API_KEY to other OpenAI-compatible providers when no key is passed, a flaw fixed on main but not yet released.

**Pipecat PhoneLLM.** PhoneLLM Mini is callable per token on Workers AI at $0.06 input and $0.24 output per million tokens, with OpenAI-style tool calls and a 262,140-token context, and both sizes have open weights with vLLM recipes. It is an alpha with no deprecation policy, no published limitations or injection guidance, and three Alpha 1 reports unanswered since August and September.

## Before you call either

### Pipecat

1. Pass `api_key` explicitly to every OpenAI-compatible service such as Groq, Cerebras or OpenRouter. On 1.12.0 a missing key sends `OPENAI_API_KEY` to that provider
2. Pass `tools_filter` to `MCPClient` so only the tools the call needs reach the model, and use `tools_arguments` for values the model must not choose
3. Gate tools that book, pay or send in your own handler. Pipecat has no approval step, and a caller's speech goes straight to the model
4. Keep the development runner on localhost. Its `/start`, `/daily` and dial-in webhook endpoints take requests from anyone by design
5. Pin a minor version and read the breaking-change flags in CHANGELOG.md before upgrading, since minor releases remove and rename APIs

### Pipecat PhoneLLM

1. Send `temperature: 0` on every call. The repositories' generation_config.json samples by default, and Max's sets temperature 1.0
2. For Max, serve with `--reasoning-parser nemotron_v3` and send `chat_template_kwargs` with `enable_thinking: true` on every request, or the reply lands in `reasoning`
3. For Mini, serve without a reasoning parser and keep `enable_thinking` false, as Cloudflare and the card say, or tool calls can be filed under `reasoning`
4. Confirm bookings, payments and transfers in your own handler before acting on a tool call, since caller speech reaches the model directly
5. Pin the model ID including `alpha-2`. Daily states no notice period, and a later alpha may replace it
