| # 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`. |

| 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. |
