+ Creative Commons Corporation (“Creative Commons”) is not a law firm and does not provide legal services or legal advice. Distribution of Creative Commons public licenses does not create a lawyer-client or other relationship. Creative Commons makes its licenses and related information available on an “as-is” basis.

+ Using Creative Commons Public Licenses
6
+
7
+ Creative Commons public licenses provide a standard set of terms and conditions that creators and other rights holders may use to share original works of authorship and other material subject to copyright and certain other rights specified in the public license below. The following considerations are for informational purposes only, are not exhaustive, and do not form part of our licenses.
8
+
9
+ Considerations for licensors: Our public licenses are intended for use by those authorized to give the public permission to use material in ways otherwise restricted by copyright and certain other rights. Our licenses are irrevocable. Licensors should read and understand the terms and conditions of the license they choose before applying it. Licensors should also secure all rights necessary before applying our licenses so that the public can reuse the material as expected. Licensors should clearly mark any material not subject to the license. This includes other CC-licensed material, or material used under an exception or limitation to copyright. More considerations for licensors.
10
+
11
+ Considerations for the public: By using one of our public licenses, a licensor grants the public permission to use the licensed material under specified terms and conditions. If the licensor’s permission is not necessary for any reason–for example, because of any applicable exception or limitation to copyright–then that use is not regulated by the license. Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material. A licensor may make special requests, such as asking that all changes be marked or described. Although not required by our licenses, you are encouraged to respect those requests where reasonable. More considerations for the public.

15
+ By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

18
+
19
+ a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.
20
+

24
+
25
+ d. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
26
+
27
+ e. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.
28
+
29
+ f. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.
30
+
31
+ g. License Elements means the license attributes listed in the name of a Creative Commons Public License. The License Elements of this Public License are Attribution, NonCommercial, and ShareAlike.
32
+
33
+ h. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.
34
+
35
+ i. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.
36
+
37
+ j. Licensor means the individual(s) or entity(ies) granting rights under this Public License.
38
+
39
+ k. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.
40
+
41
+ l. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.
42
+
43
+ m. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.
44
+
45
+ n. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.
46
+
47
+ Section 2 – Scope.
48
+
49
+ a. License grant.
50
+
51
+ 1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:
52
+
53
+ A. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and
54
+
55
+ B. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.
56
+
57
+ 2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.
58
+
59
+ 3. Term. The term of this Public License is specified in Section 6(a).
60
+
61
+ 4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material.
62
+
63
+ 5. Downstream recipients.
64
+
65
+ A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.
66
+
67
+ B. Additional offer from the Licensor – Adapted Material. Every recipient of Adapted Material from You automatically receives an offer from the Licensor to exercise the Licensed Rights in the Adapted Material under the conditions of the Adapter’s License You apply.
68
+
69
+ C. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.
70
+
71
+ 6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).
72
+
73
+ b. Other rights.
74
+
75
+ 1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.
76
+
77
+ 2. Patent and trademark rights are not licensed under this Public License.
78
+
79
+ 3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.
80
+
81
+ Section 3 – License Conditions.
82
+
83
+ Your exercise of the Licensed Rights is expressly made subject to the following conditions.
84

118
+
119
+ Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:
120
+
121
+ a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;
122
+
123
+ b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material, including for purposes of Section 3(b); and
124
+
125
+ c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.
126
+ For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.
127
+
128
+ Section 5 – Disclaimer of Warranties and Limitation of Liability.
129
+
130

Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.
133
+
134
+ c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.
135
+
136
+ Section 6 – Term and Termination.
137
+
138
+ a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

+
144
+ 2. upon express reinstatement by the Licensor.
145
+

+
150
+ d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
151
+
152
+ Section 7 – Other Terms and Conditions.
153
+
154
+ a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.
155
+
156
+ b. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

+ # Dohnuts-0.1.0-0.8B
16
+
17
+ A multimodal decision model built on Qwen3.5-0.8B. It scores supplied candidates
18
+ from text and images, returning candidate probabilities, truth estimates, or
19
+ ordered scores. Independent questions about one input share computation in a
20
+ single forward pass. The interface returns decisions without generating reasoning
21
+ or free-form answers.
22
+
23
+ ## Model details
24
+
25
+ | Property | Value |
26
+ | --- | --- |
27
+ | Base model | Qwen/Qwen3.5-0.8B |
28
+ | Training | Joint RLCD and auxiliary cross-entropy; language LoRA and a candidate scorer |
29
+ | Selection | Seed 42, update 3,600; highest development macro accuracy |
30
+ | Calibration | One temperature per decision type, fitted on an independent partition |
31
+ | Runtime | Merged LoRA, BF16, fused operations, shared input prefixes |
32
+ | Inputs | Text and one decoded image; 2–128 candidates per question |
33
+ | Context | 4,096 tokens per question at inference; 2,048 during training |
34
+ | Hardware used | One AMD Radeon RX 7900 XTX, 24 GB |
35
+
36
+ ## Use
37
+
38
+ Dohnuts is intended for tasks with explicit candidate answers: routing requests,
39
+ classifying content, estimating whether a condition holds, rating relevance, or
40
+ answering visual questions. An application supplies the choices and decides how
41
+ to act on the returned probabilities.
42
+
43
+ After [setting up the runtime](https://github.com/PsiACE/dohnuts/blob/main/docs/inference.md), load the model from Hugging Face:
44
+
45
+ ```python
46
+ from dohnuts.predictor import Predictor
47
+
48
+ model = Predictor.from_checkpoint("PsiACE/Dohnuts-0.1.0-0.8B")
49
+ ```
50
+
51
+ The compact checkpoint contains LoRA and scorer weights. The loader downloads
52
+ and caches it with the pinned base model, merges LoRA, and applies calibration.
53
+ Weights are not bundled with the Python package. See the [inference guide](https://github.com/PsiACE/dohnuts/blob/main/docs/inference.md) for question
54
+ definitions, images, and response fields, or [Bub integration](https://github.com/PsiACE/dohnuts/blob/main/docs/bub-agent.md)
55
+ for agent use.
56
+
57
+ ## Evaluation
58
+
59
+ The model achieves **78.21% macro accuracy** over 26 held-out dataset groups
60
+ containing 180,031 decisions. Each group contributes equally to this mean.
61
+ Development data selects weights; calibration data fits temperatures; test data
62
+ does neither. This is one training seed, with no estimate of variation across seeds.
63
+
64
+ ### JevBench
65
+
66
+ Accuracy on the same 231 public tasks from JevBench v1.2.2:
67
+
68
+ | Model | Correct | Accuracy |
69
+ | --- | ---: | ---: |
70
+ | Dohnuts-0.1.0-0.8B | 152 / 231 | 65.80% |
71
+ | Jev 1.13.0 | 200 / 231 | 86.58% |
72
+ | Laya multilingual | 110 / 231 | 47.62% |
73
+ | Laya Vision | 111 / 231 | 48.05% |
74
+
75
+ Jev results use published per-task outcomes; Dohnuts and the two Laya checkpoints
76
+ were measured locally. Dohnuts uses a 4,096-token limit; the Laya runs use their
77
+ native 1,024-token limit and truncation. The other 303 leaderboard tasks are
78
+ unavailable, including the judge tier. These accuracies are not the official
79
+ four-axis leaderboard score.
80
+
81
+ ### Laya task suites
82
+
83
+ Dohnuts leads the published Laya multilingual reference on the 51-language
84
+ MASSIVE intent suite, at **60.14%** versus **36.61%** language macro accuracy.
85
+ Laya multilingual leads on the 15-language XNLI suite, at **73.84%** versus
86
+ **70.91%**. The upstream question builders are preserved, but the historical
87
+ reference's input hashes are unavailable, so exact input identity cannot be verified.
88
+
89
+ Against Laya Vision on the same local image examples, Dohnuts scores higher on
90
+ A-OKVQA and VQAv2 yes/no; Laya Vision scores higher on ScienceQA and has lower
91
+ calibration error on ScienceQA and VQAv2. These runs use different precision and
92
+ have reference data-exposure limitations, documented in the
93
+ [comparison protocols](https://github.com/PsiACE/dohnuts/blob/main/docs/upstream-alignment.md).
94
+
95
+ The [comparison gallery](https://github.com/PsiACE/dohnuts/blob/main/docs/figures/README.md) includes every application suite,
96
+ language results, vision accuracy and calibration, and paired JevBench outcomes.
97

98
+ ### Inference speed
99
+
100
+ Warm end-to-end median latency on one RX 7900 XTX, using BF16 and each model's
101
+ native API:
102
+
103
+ | Workload | Dohnuts | Laya multilingual | Laya Vision |
104
+ | --- | ---: | ---: | ---: |
105
+ | Text, 1 question | 15.07 ms | 9.77 ms | 11.00 ms |
106
+ | Text, 50 questions | 112.51 ms | 47.19 ms | 125.63 ms |
107
+ | Image, 1 question | 24.43 ms | — | 75.41 ms |
108
+ | Image, 3 questions | 35.84 ms | — | 77.89 ms |
109
+
110
+ Measurements use three warmups and 20 synchronized repetitions, including
111
+ preprocessing and transfers. They exclude model loading, network, and queueing.
112
+ Image timings use warm caches. They do not measure uncached image encoding or
113
+ service throughput under load. See the [full charts](https://github.com/PsiACE/dohnuts/blob/main/docs/figures/README.md#same-hardware-inference-latency)
114
+ and [benchmark protocol](https://github.com/PsiACE/dohnuts/blob/main/docs/local-benchmarks.md).
115
+
116
+ ## Training
117
+
118
+ The mixture covers 26 text, language, and vision task groups, including public
119
+ classification, question-answering, retrieval, policy, mail, and visual datasets.
120
+ A fixed cap provides 143,238 eligible training rows; sampling is uniform over
121
+ groups with replacement. The 3,600 updates process 115,200 sampled examples.
122
+ Related documents and identical images are grouped to prevent cross-split leakage.
123
+ Dataset sources, exclusions, and terms are listed in the
124
+ [data reference](https://github.com/PsiACE/dohnuts/blob/main/docs/data-and-evaluation.md).
125
+
126
+ The base model and vision encoder are frozen. Training updates rank-8 language
127
+ LoRA adapters and a shared candidate scorer. The joint RLCD and cross-entropy
128
+ objective follows the pinned Laya and Laya Vision implementations. Its four
129
+ samples perturb decision logits; they are not generated trajectories. LoRA is
130
+ merged before temperature fitting and final evaluation. The
131
+ [RLCD specification](https://github.com/PsiACE/dohnuts/blob/main/docs/rlcd.md) gives the objective and fixed schedule.
132
+
133
+ ## Limitations
134
+
135
+ - Quality depends on the task. Jev leads on the public JevBench tasks; Laya
136
+ multilingual leads on several application suites and small text-batch latency.
137
+ - Global temperatures do not improve every dataset's calibration. The API's
138
+ `confidence` field summarizes a distribution; it is not a measured probability
139
+ of correctness. Check calibration on the intended workload.
140
+ - Candidate wording, order, and input length can affect decisions. Over-budget
141
+ inputs are rejected. A long-document result covers only the eligible subset.
142
+ - Laya Vision has possible VQAv2 training-pool exposure and A-OKVQA selection
143
+ exposure. Backbone pretraining exposure is unverified. These comparisons do
144
+ not establish performance on unseen data for every reference.
145
+ - Bub acceptance exercises the decision tool. It does not measure autonomous
146
+ planning quality.
