CHANGELOG.md

Changelog

4.3.2

• Fixed worker performances showing wrong
• Adjusted so that max resolution and tokens without kudos upfront is based on amount of workers active
• Added new api/v2/generate/async post-processor strip_background. Will remove background from image (@ResidentChief)
• Added new api/v2/generate/async param return_control_map. Will return control map instead of final image (@ResidentChief)

4.3.1

• Added new option for /async (both text and image): slow_workers.

  • If True (Default), the request will function as currently
  • If False, the request will only be picked up by workers who have a decent speed (0.3 MPS/s for Image, 2 tokens/s for Text). However selecting this option will incur a 20% Kudos consumption penalty and require upfront kudos.

  The purpose of this option is to give people the ability to onboard slower workers while also allowing other people to avoid those workers if needed.

• Added check for load on Text Gen and requirement for upfront kudos when requesting too many tokens while load is high

4.3.0

• Added RealESRGAN_x4plus_anime_6B post-processor (@ResidentChief)
• Added DDIM sampler (@ResidentChief)

4.2.0

• Added regex transparent replacements instead of IP blocks.
• New arg for /api/v2/generate/async: replacement_filter. When True (Default), it will transparently replace underage context in CSAM-detected prompts. When false (or when prompt too large) will IP block instead.
• NSFW models which hit their lightweight CSAM filter, will always replace instead of giving an error. This is to avoid people reverse engineering the CSAM regex through trial and error

4.0.0

• Massive Refactoring merged KoboldAI Horde into Stable Horde! Now you can request text generations from the same place you request your image generations and your kudos are in the same place! All new endpoints are under api/v2/generate/text/ and they work identically to image endpoints but with slightly different payloads. No need to use /check as well
• Unfortunately Users and Worker statistics and kudos could not be transferred, but KoboldAI users can transfer their existing KAI Horde kudos using a dedicated interface
• /api/v2/user: contributions and usage fields are now obsolete. Switch to the records field as they will be decommissioned
• /stats/text/totals/: New endpoints for text statistics
• /api/v2/workers should now show image, interrogation and text workers. You can filter the list using the type query. For example /api/v2/workers?type=text
• /v2/status/models should now show image and text workers. You can filter the list using the type query. For example /v2/status/models?type=text By default it is using type=image, to avoid breaking existing UIs, but this will be removed eventually so ensure your UIs take that into account.
• /v2/status/performance Now shows text performance as well

3.11.2

• Added check for controlnet models (@ResidentChief)
• Fixed Database extra bandwidth load

• Horde will now ignore unknown models
• Can now send "1girl", but not "girl" to Hentai Diffusion

3.5.0

• Worker Bridges now have to send a new field in the pop payload called bridge_agent. It should be in the form of name:version:url. For example AI Horde Worker:11:https://github.com/db0/AI-Horde-Worker

  This will allow people to better know the capabilities of each worker

• Exposed bridge_agent in the worker info

• api/v2/generate/async now supports tiling boolean in params. Check API/doc

3.4

• Restricted generic terms like girl and boy from NSFW models
• added shared boolean on api/v2/generate/status to know if a generation was shared to create the LAION dataset.

3.3

• Fixed not being able to serve models with >30 chars
• Added regex endpoint for filters
• When trying to submit on an aborted gen, will get a different error than a duplicate one

3.2

• Added Filtering API

v2.7

Features

• Increased the jobs dropped needed to think a worker is suspicious

Changelog

v2.6

Features

• Added post-processing capabilities. GFPGAN and RealESRGAN_x4plus
• Added clean shutdown capability
• Added rate limiter information to headers (@jamdon2)

Tweaks

• Adaptive samplers now consume kudos as if they are at 50 steps always.

API

Please check the API documentation for each new field.

Model ModelGenerationInputStable

Used in /v2/generate/async, /v2/generate/sync

• Added 'post_processing' key
• increased amount of models allows in 'models' key

endpoint /v2/status/modes

• Added 'shutdown' key

v2.5

Features

The horde workers can now run multiple threads. The horde has been adjusted to show proper speed when workers have multiple threads.

Countermeasures

• Anon user has a different concurrency per model. Anon can only queue 10 images per worker serving that model. That means anon cannot request images for models that don't have any workers! I had to add this countermeasure because I noticed someone queueing 500 images on a model that had very few workers, therefore choking the whole queue for other anon usage.
• Lowered limits before upfront kudos are required.
  • Now the resolution threshold is based on how many concurrent requests are currently in the queue to a min of 576x576 which will remain always available without kudos.
  • steps threshold lowered to 50
  • pseudonymous users start with 14 kudos, which will allow them to always have a bit more kudos to do some extra steps or resolution.
  • oauth users start with 25 kudos, which will allow them to always even more kudos to do some extra steps or resolution compared to pseudonymous.
• request status check is now cached for 1 second to reduce server load.
• pseudonymous and oauth users cannot transfer their starting kudos baseline.

API

Please check the API documentation for each new field.

• The new online key for workers will allow to mark which workers are currently online for each team
• Team performance now only takes into account online workers

Model WorkerDetailsLite

Used in /v2/worker/{worker_id}, /v2/teams, /v2/teams/{team_id} etc

• Added 'online' key

Model WorkerDetailsStable

Used in /v2/worker/ and /v2/worker/{worker_id}

• Added 'threads' key

v2.4

• Tweaked Blacklist
• Added 4 new samplers. Cannot use new samplers on img2img yet
• added Karras
• Extra check to avoid two workers picking up the same job
• Source mask can now be sent to img2img
• Added IP timeout for Corrupted Prompts

v2.3

Features

• Added ability to create teams and join them with workers. Each worker will record how much kudos, requests and MPS they're generated to their team. This has no utility by itself other than allowinf self-organization. The new APIs developed allow trusted users to create new teams, but anyone can dedicate their worker to a specific team by using the worker PUT. You can list all teams or query a specific one.
• Added cache to the various endpoints. My server started lagging because python started getting overwhelmed from all the calculations. This helps release some of this stress at the cost of some data not being up to date. The big APIs like /users and /workers are caching for 10 seconds, while individual users and workers and the model list do so only for a couple seconds. This is mostly to help with the hundreds of users on UIs hammering for details.

API

v2.1

Features

• Uncompleted jobs will now be restarted. A request which ends up with 3 restarted jobs will abort

• better Kudos calculation
• k_heun and k_dps now count as double steps for kudos
• Allow resolutions higher than 1024x1024 and steps more than 100. But Those requests require the user to have the kudos upfront.
