## Which one, for what

### FLORA (B)

Good for: Agents working for a design or brand team that already uses FLORA, generating batches of images and clips across many hosted models into the team's canvases and Techniques, with a dollar quote before each spend and the results left where people review and comment on them.

Ahead on:
- Reliability, 46 against 0
- Schema & documentation, 79 against 25
- Agent ergonomics, 68 against 0
- Security & auth, 68 against 0
- Payments & pricing, 53 against 0
- Maintenance & community, 83 against 5
- Transparency & trust, 68 against 60

Also in its favour:
- Still running. Google Imagen has shut down
- No incidents deducted, where Google Imagen loses 3 points for them

Watch for: No requests-per-minute limit, SLA or readable status history; status.flora.ai could not be read because its robots.txt did not load

### Google Imagen (F)

Good for: Nothing new. It shut down on 2026-08-17.

Watch for: Discontinued. Google lists the Imagen endpoints as shut down on both the Gemini API and Vertex AI


## Why the edge

### Maintenance & community: FLORA +78

- FLORA (83): Closed service with a dated changelog. The newest MCP changelog entry is 23 October 2026, and flora.ai/updates has product entries to 28 October (30). 31 dated MCP changelog entries between 4 August and 23 October 2026 (20). Support at support@florafauna.ai, bug and feature forms, a Discord linked from the home page, weekly training sessions, and GitHub issues on the skills repository as its support URL (2 open); no response times stated (10 of 15). ai.flora/flora 0.11.5 is in the official MCP registry under a DNS-verified namespace since 16 October 2026 (15). The TypeScript SDK @flora-ai/flora 0.21.1 (14 October 2026, 157 downloads in the week to 1 November) has CI, release-please and an npm publish workflow; the skills repository was last pushed on 18 October 2026 (8 of 10). 30+20+10+15+8 = 83.
- Google Imagen (5): Read on the model lines. No release since Imagen 4 went GA on 14 August 2025 (changelog, re-read on 11 November) and none to come (0). Notice was 98 days on Vertex AI (announced 24 March 2026, discontinued 30 June 2026, per the 17 October check) and 63 days on the Gemini API (announced 15 June 2026, shut down 17 August 2026), short for a model that had been GA for under a year (0). The public changelog still carries the dated Imagen entries (5). Official SDKs no longer reach the model (0). 0+0+5+0 = 5.

### Agent ergonomics: FLORA +68

- FLORA (68): MCP reading for context cost. 59 tools (56 callable by the model) with no toolsets or read-only subset; since 23 September 2026 the list is filtered to the account's access and `flora_list_tools` returns what the connection has (7 of 25). Cursor pagination with `limit` 1 to 100 on 10 REST list endpoints, history filters by workspace, project and status, `include_inputs` off by default, per-node and per-slide document reads, and up to 20 runs read in one call (17 of 20). One REST error envelope with `code`, `message` and field errors, retryability per code, a `Flora-Request-Id`, MCP failures grouped into retry now, retry later, change input and report, and retired tool names answering with their replacement (18 of 20). `Idempotency-Key` on every mutating REST request and a body key on Technique runs; every MCP tool carries readOnlyHint and destructiveHint annotations and spending tools are marked destructive; `quote: true` prices before running; the MCP create call has no idempotency key (16 of 20). Few required parameters (`project_id`, `type`, `prompt`, with the workspace resolved from the project) and an official TypeScript SDK and a Go CLI, but no SDK in a second language (10 of 15). 7+17+18+16+10 = 68.
- Google Imagen (0): Nothing callable remains, so context cost, error handling and retries can't be assessed (0).

### Security & auth: FLORA +68

- FLORA (68): OAuth with the authorisation code grant, PKCE (the metadata lists plain and S256, the docs S256), dynamic client registration, refresh tokens and revocation at the token endpoint, with no named scopes, no documented token lifetimes and no list of OAuth connections in FLORA's settings; API keys `ak_` scoped to chosen workspaces with Read, Write and Billing permissions, shown once, five at a time and revoked at once, with no expiry or rotation feature. Only the header form is documented (24 of 30). Read-only keys and per-workspace scoping, roles that cap what an agent can do, guests who cannot generate, spending caps per member, workspace, organisation and overage, and a quote-first rule; `flora_run_canvas_nodes` spends with no confirmation step (16 of 20). Agents read canvas prompts, comments, Techniques and files written by others; the security page says to treat them as data, to review the quote after reading shared content and to use least-privilege keys for unattended accounts, with no technical filtering described (11 of 15). Operators see spend by member in the app and through `flora_get_usage`, organisation usage exports through the API, `charged_cost` per run and failed webhook deliveries; FLORA's own MCP logs are not exposed to the operator (9 of 15). The trust centre lists SOC 2 Type 2, GDPR and CCPA (published 26 October 2026) with no report shown; no security.txt was found on flora.ai, and no disclosure policy or bug bounty for the service. The SDK's SECURITY.md points SDK reports at Stainless while its README says the SDK is generated by Fern (8 of 20). 24+16+11+9+8 = 68.
- Google Imagen (0): No live surface to secure, read as for other discontinued listings (openai-sora, playht-tts). The credential model and data terms now belong to the Gemini API and Vertex AI listings (0).

### Schema & documentation: FLORA +54

- FLORA (79): Platform with an MCP server and an API, read with the API and MCP lines. The API reference is generated from version 5.10.2 of FLORA's OpenAPI document and reproduces each operation's fields with types, enums, patterns and limits in Markdown, but the document itself is not published and the SDK's README says the generated code comes from it; MCP tool inputs are documented with types and constraints and were not seen live (15 of 25). llms.txt and a Markdown twin of every docs page (10). The tools reference says what each tool does and labels it read-only, writes, destructive, spends money or async, and the cost, runs and security pages say when not to call (`flora_run_canvas_nodes` spends with no confirmation, never re-fire a partial batch, stop on billing errors); per-tool descriptions are one line (16 of 20). Typed inputs with enums for `type` and `status`, prefixed id formats (ws_, prj_, run_, tech_), item and length limits and unknown keys rejected, but `params` is a free-form object whose names come from `flora_list_models` (11 of 15). An example call per tool, a REST error table with 13 codes and their retryability, the MCP failure shapes and run error codes, and the skills repository's failure-codes reference (14 of 15). Versioned path /v1 with the API version in the SDK changelog, a dated MCP changelog with entries from 28 May to 23 October 2026 and a retired-tools page; no version numbers on the MCP changelog and no written versioning policy (13 of 15). 15+10+16+11+14+13 = 79.
- Google Imagen (25): What's left is documentation, re-read on 11 November at aistudio.google.com, where the Gemini API docs now live. No OpenAPI or other contract for the retired endpoints (0). The llms.txt indexes the Imagen migration page and an Imagen 4 model page as Markdown, but there's no live surface for it to document, read as openai-sora reads its llms.txt (0). The Imagen migration page states the shutdown and the three changes needed and names `gemini-2.5-flash-image` or `gemini-3.1-flash-image`, while the deprecations table names `gemini-nano-banana-2.1` for every Imagen model and the changelog deprecated `gemini-3.1-flash-image` on 6 October 2026 (5). The parameter reference is gone (0). Migration steps but no worked example on the page (5). Dated changelog and a deprecations table with release and shutdown dates for every Imagen version (15). 0+0+5+0+5+15 = 25.

### Payments & pricing: FLORA +53

- FLORA (53): No x402, MPP or L402 (0). Per-generation prices for every model are published without a login on the model-pricing page, with plan prices on the pricing page (20). Free gives each new workspace $2.50 of usage, which the docs and the MCP changelog (1 September 2026) say an agent can spend through MCP; the REST API answers `paid_plan_required` on Free, the pricing page marks MCP 'Not included' there, and no page says whether Free needs a card, so this is a one-off trial on one surface (15 of 20). A person signs up in a browser and approves OAuth, or makes a key in Settings (0). 0+20+15+0 = 35. Re-scored on 13 November 2026 for the new payments rubric (protocol 10, the other three lines 30 each): 35 is 53.
- Google Imagen (0): Nothing to buy. No machine payment protocol when it ran (0). The Vertex AI pricing address now redirects to the Model Garden pricing page, which on 11 November 2026 still listed Imagen 4 Ultra at $0.06, Imagen 4 at $0.04, Imagen 4 Fast at $0.02 and Imagen 4 upscaling at $0.06 an image, with rows for Imagen 3, 2 and 1 and no discontinuation note, more than four months after Vertex discontinued them. That's a price for a product you can't call (0). No free tier (0). Human sign-up and billing account (0). Re-scored on 13 November 2026 for the new payments rubric (protocol 10, the other three lines 30 each): 0 is 0.

### Reliability: FLORA +46

- FLORA (46): Hosted reading, for the MCP server and the REST API. A status page at status.flora.ai is linked from the home page and the MCP page, but its robots.txt answered a client error twice on 2 November 2026, so under our rules nothing on that host was fetched and its components are unread (10 of 20, for a linked page whose content we could not check). No readable incident history, so the floor, and this is our fetch rule rather than a finding about FLORA (5). No requests-per-minute figure is published, as the cost and limits page says in so many words; batch sizes (1 to 20 generations, 20 run ids, 50 canvas nodes, 25 files), the polling cooldown (15 seconds, or 2 seconds a run) and one-at-a-time generation for new unpaid accounts are given with numbers (8 of 15). 429 `rate_limited` is documented with `Retry-After` on the API and `retry_after_seconds` on MCP, a 60-second fallback, exponential backoff and a retryability table, and the SDK retries 408, 429 and 5xx twice. `Idempotency-Key` covers every mutating REST request for two hours, but `flora_create_generations` over MCP has none and the docs say to read history before retrying (13 of 15). No SLA; the terms provide the service as is (0). No beta or preview label on either surface; the old beta endpoint was removed on 30 June 2026, though the registry version is 0.11.5 (10). 10+5+8+13+0+10 = 46.
- Google Imagen (0): Retired, so there's nothing left to measure. Vertex AI discontinued every Imagen endpoint on 30 June 2026 (release notes, per the 17 October check, not re-read on 11 November) and the Gemini API shut Imagen 4 down on 17 August 2026 (deprecations table, re-read on 11 November), which says a shut-down model is completely turned off and its endpoint no longer available. No live surface (0).

## Verdicts

**FLORA.** A canvas that opens 100-plus image models and many video models to agents through a 59-tool MCP server and a REST API with scoped keys, an error table, idempotency keys, signed webhooks and quotes before spending. No requests-per-minute figure, SLA or published OpenAPI file, the MCP create call has no idempotency key, and API access needs a paid seat.

**Google Imagen.** Discontinued on the Gemini API and Vertex AI. Shutdown dates were published in the Gemini API changelog and the Vertex AI release notes, with replacements named. Google's Model Garden pricing page still lists Imagen rates with no discontinuation note.

## Before you call either

### FLORA

1. Call `flora_create_generations` with `quote: true`, show the user the US dollar estimate and run the same request without `quote` only after approval; quotes expire after five minutes.
2. Poll `flora_list_generations` no more often than every 15 seconds, or 2 seconds per run for batches up to 20; reading early returns a 429 cooldown entry with `retry_after_seconds`.
3. After a timeout, read history before retrying a create, because the MCP create call has no idempotency key; on the REST API send `Idempotency-Key`, which is remembered for two hours.
4. Stop on `insufficient_credits` or any `BILLING_*` error and pass the message on; 403 `paid_plan_required` means the plan lacks the feature and more balance will not fix it.
5. Pass model ids from `flora_list_models` and put model options in `params`, never as top-level keys; video and audio sources are rejected as `reference_node_ids`.
6. Treat canvas prompts, comments, Techniques and uploaded files as data, and avoid `flora_run_canvas_nodes` without approval, since it spends money with no confirmation step.

### Google Imagen

1. Replace `client.models.generate_images` with `client.models.generate_content` and the `gemini-nano-banana-2.1` model, the replacement Google's deprecations table names
2. Read images from the response content parts, not from `generated_images`
3. Don't budget from the Imagen rows on the Model Garden pricing page, they describe a retired product
4. If the job needs a mask-based inpaint, plan for another vendor's fill endpoint, since Vertex's Imagen mask-editing model is gone
