|---|---|---|---|
| What it is | Voice infrastructure company built on state-space models. Sonic 3 does text-to-speech in 40-plus languages with emotion controls, laughter tags and voice cloning from a 3-second sample. Ink handles speech-to-text and Line orchestrates phone-based voice agents. | Adobe's generative suite, currently on Firefly Image 5, trained on Adobe Stock, openly licensed and public-domain material rather than scraped web images. Now also brokers third-party models and generates video. Credit cost varies by model: Image 5 is 10 credits, Image 4 Ultra 20. | The FLUX family from the ex-Stable Diffusion team. FLUX.2 ships as klein, dev, pro, flex and max; FLUX 3 landed 26 July 2026 as one multimodal model doing image, 20-second video with native audio, and robot action prediction, still in gated early access. |
| Category | AI media generation | AI media generation | AI media generation |
| Cost tier | mixed | mixed | mixed |
| Pricing | Free 20K credits, personal use only. Pro $5/mo (100K), Startup $49 (1.25M), Scale $299 (8M). TTS is 1 credit/character, Ink STT 1 credit/second, Line voice agents $0.014/min. | Free tier with limited watermarked credits. Standard $9.99/mo (2,000 credits), Pro $19.99 (4,000), Premium $199.99 (50,000). API is enterprise contract only. | API per image: FLUX.2 klein from $0.014, pro from $0.03, flex $0.05, max $0.07. Kontext pro $0.04, max $0.08. Open weights free to self-host. |
| Why builders pick it | Around 90ms time-to-first-audio, and 40ms on Sonic Turbo - fast enough that a phone agent never sounds like it is thinking. That latency, not raw voice beauty, is why realtime builders pick it over ElevenLabs. | The pick when legal sign-off matters more than raw quality: Adobe offers IP indemnification to enterprise customers, which no other major generator does. Deep native integration into Photoshop, Illustrator and Express beats any bolt-on plugin. | The pragmatic pick when image generation lives inside your own product: cheap per-image API, plus dev and klein open weights you can run on your own GPUs with no per-call fee. Kontext remains the best instruction-based image editor. |
| Watch out for | The free tier is personal use only; any commercial deployment needs at least the $5 Pro plan. Pro voice cloning bills at 1.5 credits per character rather than 1, so cloned-voice costs run 50% above the headline rate. | Free-tier outputs are watermarked. Consumer plans include no API access at all - Firefly Services is an enterprise sales contract with no published rate card, and community reports suggest a starting commitment near $1,000/month. | Open weights are not an open licence - dev and klein are non-commercial unless you buy a BFL commercial self-hosting licence. FLUX 3 access is staged and gated: video first, image later, open weights last. |
| How to wire it up | Low-latency streaming API with WebSocket support; SDKs for Python, Node and Rust. | Firefly Services API is enterprise-only via Adobe Sales; there is no self-serve developer tier. | Direct REST API at api.bfl.ai, plus resale through fal, Replicate and Together. |

Prefer the free tier when no budget was stated, and say what the ceiling is. 2. Read the full dossier before integrating. 3. Fetch /api/public/models before writing any AI model ID.
