# FREESTREAM 🚀

> **Free-tier avatar-meeting agent** — joins calls, speaks with an on-device voice,
> wears an animated avatar, and roleplays as an agent that can work a real terminal.
> CLI-compatible drop-in for [Pika's pikastream-video-meeting](https://github.com/Pika-Labs/Pika-Skills)
> ($0.20–0.28/min hosted) at **$0/min marginal cost**.

**A universal, free-tier avatar-meeting skill.** Clean-room reimplementation,
CLI-compatible with [`Pika-Labs/Pika-Skills` — pikastream-video-meeting](https://github.com/Pika-Labs/Pika-Skills)
(Apache-2.0). Same CLI surface, same exit codes, same output JSON — any agent
trained on the Pika skill works unchanged. The metered hosted pipeline is
replaced by swappable local drivers.

## Measured results (8 vCPU, CPU-only — docs/LATENCY.md)

| Metric | Result |
|---|---|
| Win condition (assistant profile) | **t_perceived 2.94s ≤ 4.0s — PASS** |
| Agentic roleplay e2e | **17/17 — ROLEPLAY E2E OK** |
| ASR finalize (whisper tiny.en int8, 1 thread) | 1.33s |
| First-audio TTS path (cached disclosure) | ~0.2s |
| Full turn (14.9s of speech) | 18.9s, pipelined |
| Session replay | both hash chains verify |

This is **v0.1.0 — MVP slice working and measured**: the LiveKit presence driver,
faster-whisper ASR (utterance VAD → transcribe), Piper TTS with sentence-level
streaming, and the audio-reactive procedural avatar all run end to end. The
win condition — *agent joins, answers within 4s with a moving mouth, leaves,
and produces a valid replay log* — **passes: t_perceived = 2.94s on 8 vCPU,
CPU-only, both turns answered via speculative dispatch** (measured 2026-10-04,
job 6ac2e756404719ba37651973, see docs/LATENCY.md). Remaining stubs: the
browser join-pack (Meet/Zoom), the SIP driver, and local portrait-model rungs.

## The three-layer split

| Layer | Job | Drivers (preference order) |
|---|---|---|
| Presence | Get a participant into the call, own an A/V track | `livekit` (free, low jitter) → `browser` (Playwright + virtual cam) → `sip` (audio-only) |
| Persona | A face and a voice | Fidelity ladder: FULL_PORTRAIT → VISEME_STILL → AUDIO_REACTIVE_WAVE → STATIC_CARD; Piper TTS, local-only clones |
| Cognition | The agent, unchanged | MCP: `session.observe` / `speak` / `listen` / `leave` |

## Quick start

```bash
pip install -r requirements.txt

# What can this host deliver?
python scripts/freestream.py probe

# Join (MVP slice targets Jitsi / LiveKit first)
python scripts/freestream.py join --meet-url <url> --bot-name <name> \
  --image identity/videomeeting-avatar.png

# Drive the session as an agent
python -m freestream.mcp_server
```

## CLI surface (Pika-compatible)

```
freestream join  --meet-url <url> --bot-name <name> --image <path>
                 [--voice-id <id>] [--system-prompt-file <path>]
                 [--system-prompt <text>] [--meeting-password <pw>]
                 [--platform jitsi|livekit|google_meet|zoom] [--timeout-sec 90]
freestream leave --session-id <id>
freestream generate-avatar --output <path> [--prompt <text>]
freestream clone-voice --audio <file> --name <name> [--noise-reduction]
freestream probe                              # FREESTREAM addition: capability negotiation
```

**Exit codes** — preserved from Pika, one repurposed:

- `0` ok · `1` configuration (FREESTREAM addition) · `2` validation ·
  `3` transport · `4` session · `5` timeout
- `6` **capability shortfall** (was Pika's *funding*). Stdout JSON carries
  `capability` + `remediation` instead of `checkout_url`.

`join` emits `{"session_id", "platform", "status": "created"}` immediately,
then status-change lines, exactly like the Pika CLI — agents that parse that
stream keep working.

## Latency trade-off

~2.5–4.5s perceived turn on CPU vs. Pika's ~1.5s hosted (~1.2–2.0s with
GPU). Mitigated by 600ms speculative dispatch, sentence-level pre-roll, and
avatar motion starting ~150ms before audio. See `docs/LATENCY.md`.

## Privacy

Face and voice clones never leave the device. Hosted clones (Pika/MiniMax)
expire after 7 days of non-use; FREESTREAM clones are local files. Consent
and disclosure defaults: `docs/CONSENT.md`.

## Attribution & license

Apache-2.0. Clean-room reimplementation of the CLI contract of
[pikastream-video-meeting](https://github.com/Pika-Labs/Pika-Skills/tree/main/pikastream-video-meeting)
by Pika Labs — no source code ported; the interface (CLI flags, exit codes,
output JSON, SKILL.md agent flow, `life/` identity-file conventions) is
preserved for agent compatibility. The hosted PikaStreaming service is
replaced, not reimplemented.
