Tagline	OpenAI's open-source daemon that turns your Linear board into an always-on coding agent factory — tickets go in, pull requests come out.	Commercially safe image gen, deeply integrated with Photoshop.	OpenAI's video model. Long clips, cinematic quality.	AI search done right. Cited answers, not chat theater.
Category	Agents	Image	Video	Research
Pricing	Free (open-source)	Free + included with Creative Cloud	Included with ChatGPT Plus/Pro	Free + $20/mo Pro
Best for	Engineering teams already using Linear + OpenAI Codex who want to stop babysitting agent sessions and instead let the issue tracker drive autonomous coding at scale.	Anyone in Creative Cloud. Brands that need copyright clarity.	ChatGPT subscribers experimenting with cinematic shots.	Replacing Google for any question where you want a cited answer in seconds.
Strengths	Fully autonomous ticket-to-PR pipeline: every open Linear issue gets its own isolated Codex agent without manual supervision Fault-tolerant Elixir/OTP architecture automatically restarts crashed agents and manages hundreds of concurrent runs WORKFLOW.md keeps all orchestration policy version-controlled inside the repo, so agent behavior is reproducible and reviewable like code Proven internal results: OpenAI reported a 500% increase in landed PRs on some teams within three weeks Open spec encourages community re-implementations in any language, not just Elixir	Trained on licensed content — commercially safe Generative Fill in Photoshop is incredible Native to Adobe ecosystem	Up to 20-sec clips at 1080p Strong physics + scene composition Storyboard feature for longer narratives Remix existing videos	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context
Weaknesses	Currently only supports Linear as an issue tracker — GitHub Issues and Jira integrations are not yet official Only OpenAI Codex is officially supported as the agent runtime; other model integrations are community-contributed and incomplete Self-hosted, Elixir-dependent engineering preview with no built-in sandboxing — not suitable for untrusted or production environments out of the box	Aesthetic ceiling below Midjourney Tied to Adobe subscription	Stricter content policy than competitors Hit-or-miss on complex motion Text-in-video still struggles	Not a general chatbot Answers can be shallow on complex topics
Kai's verdict	Symphony is the most architecturally serious 'issue tracker as control plane' approach yet — 15K GitHub stars in weeks confirms the idea resonates — but it's still a rough, self-hosted engineering preview that demands Elixir chops and a Linear-only workflow. (Verdict pending Phi's full review.)	S-tier inside Photoshop (Generative Fill). B-tier standalone.	A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
