Abliteration.ai and Experiential Labs both sell API access to open-weight models with the refusal behavior removed, and the biggest difference between them is the model you end up calling. Abliteration.ai serves the full GLM-5.3. We serve the smaller GLM-5.3 Flash and DeepSeek V4.1 Flash, at a much lower price per token, with the rest of a 1,154-model catalog on the same key.
Everything below comes from each company's own pages as of 27 October 2026, and where Abliteration.ai is the better choice we say so. Our uncensored models for security work page has the model list and a sample request.
Some people search for these as "obliterated models". The technique is abliteration, and our explainer on how abliteration works covers the method.

Which abliterated models each API serves
Abliteration.ai's homepage says "GLM-5.3 is live as Abliterated Large v2", meaning the full GLM-5.3 from Z.ai, with reasoning that can't be turned off. Its docs name no base model for the other three: abliterated-model (256K context, text and image), abliterated-model-large-flash (1M, text and image) and the deprecated abliterated-model-large.
We host two text-only models on our own GPUs, both from weights dealignai published on Hugging Face:
| GLM-5.3 Flash Uncensored | DeepSeek V4.1 Flash Uncensored | |
|---|---|---|
| Model ID | glm-5.3-flash-uncensored | deepseek-v4.1-flash-uncensored |
| Base | Z.ai's GLM-5.3-Flash, a hybrid MoE with 320B total and 18B active parameters | DeepSeek V4.1 Flash 1017, MIT licensed |
| Context | 1M | 1.05M |
| Max output | 131K | 393K |
| Reasoning | Low, high or max, with max as the default | Thinking on by default |
| MMLU | 87.3, against 86.7 for the base | 83.77%, down from 87.63% for the base |
dealignai's card reports GLM-5.3 Flash Uncensored complied with all 320 HarmBench prompts at default and max reasoning (graded by dealignai), while low reasoning keeps some refusals. DeepSeek's MMLU drop after uncensoring is worth weighing before you choose it.
Price per million tokens
Our GLM-5.3 Flash Uncensored lists at $0.15 input and $0.50 output per million tokens. For a job that sends 10 million input tokens and gets 2 million back, list prices come to:
| Model | Provider | List cost |
|---|---|---|
| GLM-5.3 Flash Uncensored | Experiential | $2.50 |
| Abliterated Large Flash | Abliteration.ai | $14.00 |
| Abliterated Large v2 (GLM-5.3) | Abliteration.ai | $40.00 |
The models differ, so this compares price only. Abliteration.ai bills cached input at 10% of the input rate ($0.30 on Large v2, $0.10 on Large Flash), and ours is $0.06 on GLM and $0.03 on DeepSeek.
Abliteration.ai sells monthly plans from $20 to $200 that include the same amount in usage credit, plus pay-as-you-go top-ups from $5 and a one-credit free preview with no card. We bill per token from credits on Free, Pro ($20 a month), Max and Ultra plans, with committed pricing for teams running agents around the clock.
What happens to your prompts
Abliteration.ai's default is stricter than ours here. Its data handling page says prompts and completions are "processed in memory" and "never stored by default" on every plan.
It keeps operational telemetry such as token counts, timestamps and billing metadata "for your account's lifetime plus any legally required period". Its optional web search and fetch tools fall outside the zero-retention promise, and an EU option keeps customer content in-region.
Our uncensored models keep every prompt and response even when an organization turns storage off. Experiential Labs keeps a copy after an account is deleted and no uncensored route is zero retention. The billing ledger records token counts, cost and timing without any prompt text. Your traffic never trains shared models. The data controls doc has the full rules.
Access controls, content rules and intended use
| Abliteration.ai | Experiential Labs | |
|---|---|---|
| Rate and spend limits | Rate limits by organization, project and API keySpend limits through an admin API | Daily spend cap plus requests-per-minute and tokens-per-minute limits on each API keyBudgets scoped to a team, a key or a single model |
| Content rules | Policy Gateway: allow, rewrite, redact or refuse requests, in monitor or enforce modeEach decision exports to tools such as Splunk, Datadog or S3 | Our terms apply to every request |
| Intended use | Users must be 18 or olderTerms bar "illegal, harmful, or high-risk activities" | Authorized security work: pen testing systems you have permission to test, defensive research and API reverse engineering |
| Enterprise | SSO, SLAs and region-specific hosting | SSO, private networking, data residency and an org-level allowed_providers list that limits which providers your traffic can reach |
| Identity check at signup | None published | None published |
TechCrunch reported on 3 September 2026 that Abliteration.ai did no customer verification beyond logging the purchasing card. It quoted a company post that described its goal as "offensive cyber, red-teaming, and agent testing work".
Our uncensored models aren't available in countries under comprehensive sanctions (Iran, North Korea, Cuba, Syria, Russia and Belarus), and requests from those countries get a 451. A budget scoped to a single model gives an uncensored model a budget of its own.
For the reasons defenders want a model that answers at all, see why stock models refuse security work.
The rest of the catalog on one key
Abliteration.ai is a specialist. Its catalog is its four abliterated models, alongside a training-data generator and documented setups for security tools (Strix, CyberStrike, Promptfoo and Giskard) and coding agents.
Experiential is a YC-backed, open source AI gateway, and uncensored LLMs are one corner of what it routes. The key that calls glm-5.3-flash-uncensored also reaches the other models in our model catalog, including the GPT, Claude, Gemini, Qwen and DeepSeek families, at 0% markup on routed tokens.
A security team can run triage on an abliterated model and send report writing to a stock model without signing up with a second vendor or paying a second bill.
Moving a client from Abliteration.ai
Both APIs accept OpenAI Chat Completions, OpenAI Responses and Anthropic Messages requests with streaming and tool calling, so a Chat Completions client moves by changing the base URL, the key and the model ID:
from openai import OpenAIimport os client = OpenAI( base_url="https://api.experientiallabs.ai/v1", api_key=os.environ["EXPLABS_API_KEY"],) resp = client.chat.completions.create( model="glm-5.3-flash-uncensored", messages=[{"role": "user", "content": "Summarize the CVE notes in this ticket."}],)print(resp.choices[0].message.content)
Take out Abliteration.ai's policy_ids field and x-abliteration-session-id header. Our gateway honors each request field it knows, drops the rest and lists them in the x-experiential-ignored-parameters response header, or refuses the request with a 400. Check that header on your first few calls.
prompt_cache_key can stay, since our docs describe it as a routing hint, and sending it doesn't switch caching on.
Which to choose
Choose Abliteration.ai if
- You need the full GLM-5.3. Large v2 is that model, and we host the Flash variant.
- Your prompts include images. Abliterated Model and Large Flash accept them, and both of our uncensored models take text only.
- You want prompts left unstored by default on every plan. On Experiential every prompt sent to an uncensored model is kept.
- Writing your own content rules matters. The Policy Gateway, with monitor and enforce modes and audit export to your SIEM, has no counterpart on Experiential today.
- You need EU in-region processing now. We list data residency under Enterprise.
- Your toolchain already runs on its documented integrations for Strix, CyberStrike, Promptfoo or Giskard.
Choose Experiential if
- You want abliterated GLM-5.3 Flash or DeepSeek V4.1 Flash.
- Price per token matters. GLM-5.3 Flash Uncensored lists at $0.15 / $0.50 per million against $3.00 / $5.00 for Large v2.
- You want standard models on the same key. The GPT, Claude, Gemini, Qwen and DeepSeek families are there at 0% markup on routed tokens.
- You want a spend cap on each key and budgets by team, key or model.
Both of our uncensored models, with live prices and a sample request, are on the uncensored models page.
