Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Gemini Omni 1.2 Flash +68

Gemini Omni 1.2 Flash 83

Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Released and generally available on 5 November 2026; the SDKs added it to the Interactions model list on 10 November (30). Deprecations with earliest dates and no stated minimum notice (4 of 12). Churn in Google's video line: every Veo model on the Gemini API shut down by 22 October, and from 3 December 2026 requests to Omni 1.1 Flash are routed to 1.2 Flash and billed at its rates, four weeks after this release (4 of 8). Dated SDK and platform changelogs (15). SDK replies not sampled (5 of 10). Current SDKs in five languages (15). Runtimes stated (10). 30 + 4 + 4 + 15 + 5 + 15 + 10 = 83.

OpenAI Sora API 15

Read on the model lines. No release since the 2025-12-08 snapshot and none to come; the changelog re-read on 11 November has no video entry since the removal (0). Notice was six months, from 24 March to 24 September 2026, which meets OpenAI's published minimum of at least six months for generally available models, but no replacement was named (15). No public channel for Sora remains (0). The official SDKs live on, but they no longer reach a video model (0). 0+15+0+0+0 = 15.

Schema & documentation Gemini Omni 1.2 Flash +54

Gemini Omni 1.2 Flash 69

Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Called through the Interactions API, which the platform's Discovery document doesn't type; the SDK's generated Interactions types list the model (10 of 25). llms.txt with Markdown twins (10). The Omni guide, read on 11 November, covers Omni 1.1 Flash on the same API and lists what isn't supported (system instructions, temperature, negative prompts, audio references, YouTube sources) and the regional limits; it doesn't name 1.2 (16 of 20). Aspect ratio (16:9 or 9:16), resolution (360p, 720p, 1080p, 4k) and delivery are enumerated; length is set in the prompt, not a field (10 of 15). REST and SDK examples; a failed generation sets the file state to FAILED, and other error codes aren't documented beyond the platform's page (8 of 15). Dated SDK and platform changelogs (15). 10 + 10 + 16 + 10 + 8 + 15 = 69.

OpenAI Sora API 15

What's left is the record. No live contract or reference for /v1/videos to grade (0 for the contract, llms.txt coverage, descriptions, typed inputs and examples). The video generation guide, re-read on 11 November, still opens with a banner saying the Sora 2 models and Videos API were shut down on 24 September 2026, that no one-to-one replacement API is available and that the guide is kept for historical reference, but it describes an API that can't be called and names no migration path, so it earns nothing here. The deprecations page lists the API and all five model IDs and snapshots with the announcement (24 March 2026) and removal (24 September 2026) dates (15).

Agent ergonomics Gemini Omni 1.2 Flash +54

Gemini Omni 1.2 Flash 54

Read on the lines the Veo listing used for video models. Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Per the Omni guide (written for 1.1 on the same API), the video comes back in the response, inline as base64 or as a Google-hosted file to poll until ACTIVE with delivery uri for outputs over 4 MB (12 of 15). No callback (0 of 10). Resolution, aspect ratio and delivery control output size, and edits run turn by turn through previous_interaction_id without regenerating from scratch (10). No list of past jobs found (0 of 10). Standard Google error statuses on the platform, with FAILED as the only Omni-specific state (12 of 14). No idempotency key, and whether failed generations are billed isn't stated (5 of 20). Only model and input are required, with 720p and 16:9 as defaults, and SDKs in five languages plus the CLI (15). 12 + 0 + 10 + 0 + 12 + 5 + 15 = 54.

OpenAI Sora API 0

Nothing callable remains, so context cost, errors and retries can't be assessed (0).

Security & auth Gemini Omni 1.2 Flash +50

Gemini Omni 1.2 Flash 50

Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Keys bound to a service account and restricted to the Gemini API, with no scopes and a token accepted in the URL (15 of 30, the platform's deduction). The pricing page, read on 11 November, lists no free tier for Omni 1.2 Flash, and paid-tier content isn't used to improve Google's products (15 of 20). Retention of generated videos isn't stated in the guide (5 of 15). Request logs described for Generate Content, not confirmed for Interactions video calls (10 of 15). security.txt and a reward programme, no certification naming the API (5 of 20). Outputs carry a SynthID watermark, and uploads of minors and some recognisable people are refused in the EEA, Switzerland and the UK. 15 + 15 + 5 + 10 + 5 = 50.

OpenAI Sora API 0

No live surface to secure, read as for other discontinued listings (smithery, playht-tts). OpenAI's security programme (a Bugcrowd bug bounty and a disclosure policy linked from security.txt on openai.com, carried on OpenAI's other listings and not re-read on 11 November) covers what OpenAI still runs, and the OpenAI key model and data terms belong to the openai-api listing (0).

Reliability Gemini Omni 1.2 Flash +45

Gemini Omni 1.2 Flash 45

Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Status page at aistudio.google.com/status with no readable components or history (10 of 20) and no readable incident record (5 of 30). Platform rate-limit tiers; the public rate-limit page has no Omni 1.2 row (5 of 15). Backoff guidance for 429 and 503 and SDK retries (15). No SLA read for the Gemini API route, and the Omni guide says provisioned throughput isn't supported there; Google's post puts it on Google Cloud (0). Google's post of 5 November says generally available, and the SDK commit marks the model GA (10). 10 + 5 + 5 + 15 + 0 + 10 = 45.

OpenAI Sora API 0

Retired, so there's nothing left to measure. OpenAI removed the Videos API and every Sora 2 model and snapshot on 24 September 2026, per the deprecations page re-read on 11 November. status.openai.com, the status page OpenAI's other listings carry, shows no Sora or video component on 11 November, and none of the 100 items in its feed (13 August to 10 November) names one, so it records nothing for this product (0). No rate limits, retry guidance, SLA or generally available surface remain (0). We sent no request to the API to test it.

Payments & pricing Gemini Omni 1.2 Flash +30

Gemini Omni 1.2 Flash 30

Model reading for gemini-omni-1.2-flash on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. No machine payment protocol (0).

How the scores have moved

Verdicts

Gemini Omni 1.2 Flash

Google's generally available video model makes clips of up to 15 seconds with audio, edits them turn by turn and upscales drafts to 1080p or 4K, from $0.023 a second at 360p to $0.209 at 4K. It is paid only, the guide still describes Omni 1.1, and every quality claim is Google's.

OpenAI Sora API

Six months' notice, from 24 March to 24 September 2026. Shut down on 2026-09-24, so every call fails.

Before you call either

Gemini Omni 1.2 Flash

  1. Call POST /v1beta/interactions with model gemini-omni-1.2-flash and response_format type video; Veo is gone from the Gemini API
  2. Set delivery to uri for clips over 4 MB and poll the file until ACTIVE; a later GET returns base64 only
  3. Edit with previous_interaction_id and leave store on, or the clip can't be edited in a later turn
  4. Set length in the prompt with timecodes such as [0-3s]; there is no duration field
  5. Draft at 360p or 720p and upscale only the keepers: 4K costs about nine times 360p

OpenAI Sora API

  1. Don't call /v1/videos. The Videos API was removed on 2026-09-24
  2. Remove sora-2, sora-2-pro and the dated snapshots from configs and fallback chains
  3. Pick another provider from this category. OpenAI has no video model on its API now
