Hoshi 1.0

Hoshi 1.0 is our proprietary frontier model, purpose-built for agentic workloads. It delivers frontier-tier performance on coding, structured output, and tool-use benchmarks at a fraction of the credits of leading alternatives.

Why Hoshi 1.0?

Hoshi 1.0 is designed from the ground up for the kinds of tasks Odin AI Platform agents perform every day: reasoning over documents, calling tools, generating structured output, and following multi-step instructions. It is not a general-purpose chatbot — it is an agent engine.

Credits, Not Dollars

Frontier-level quality at a fraction of the credits of GPT 5.5 or Sonnet 5.

OpenAI-Compatible

Drop-in Chat Completions API — change three lines and keep your stack.

No Lock-In

Standard request/response shape. Switch back or route around us anytime.

Pricing

Hoshi 1.0 uses a simple credit-based pricing model. No subscription is required for raw API access.

Tier	Credits
Input	150 / 1M tokens
Cached Input	10 / 1M tokens (~15× cheaper than fresh input)
Output	300 / 1M tokens

Credits are the universal unit across Shogo. Agent plans (Free / Basic / Pro / Business) include a monthly credit allotment — see the pricing page for details.

When to Use Hoshi vs. Frontier Models

Choosing the right model depends on the task. Use the guide below to decide when Hoshi 1.0 is the best fit and when you might reach for a frontier model like Sonnet 5 or GPT 5.5.

Use Hoshi 1.0 When…

Scenario	Why Hoshi Wins
Tool calling & function use	Purpose-tuned for reliable, low-latency tool invocations — the core of any agent.
Structured output (JSON, tables)	Consistently produces valid, schema-conformant output without retries.
Multi-step reasoning	Excels at chaining actions, parsing responses, and deciding next steps.
High-volume batch tasks	At 150 credits / 1M input tokens, running thousands of agent turns is economical.
Knowledge Base retrieval	Optimized for RAG-style workflows — grounding answers in your documents.
Cost-sensitive production	Same quality tier as frontier models at a fraction of the credits.
Code generation & refactoring	Sweeps coding benchmarks; generates, edits, and reviews code reliably.

Use a Frontier Model When…

Scenario	Why a Frontier Model May Be Better
Ultra-long context (> 200K tokens)	Models like Claude Sonnet 5 or GPT 5.5 support very large context windows for massive document analysis.
Cutting-edge multimodal reasoning	When you need best-in-class vision, audio, or cross-modal understanding.
Highly creative / open-ended writing	Frontier models may produce more varied, stylistically rich prose for marketing or storytelling.
Regulatory or compliance constraints	Some organizations require a specific provider’s model for data governance reasons.
Research-grade tasks	When you need the absolute latest capability on a novel, unstructured problem.

For most Odin AI Platform agent workloads — tool calling, structured output, RAG, and multi-step automation — Hoshi 1.0 is the recommended default. Use frontier models only when you have a specific reason to do so.

Getting Started

Hoshi 1.0 is available in Odin AI Platform as a predefined model. No API key configuration is required.

Select Hoshi in Your Agent

Navigate to Agents

Go to Agents in the sidebar.

Open or create an agent

Select an existing agent or create a new one.

Go to the General tab

Open the General tab in the agent configuration.

Select Hoshi 1.0

Find the Model drop-down selector and choose Hoshi 1.0 from the list.

Use via API

Hoshi 1.0 is fully OpenAI-compatible. Point your existing client at the Shogo API:

curl https://api.shogo.ai/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "hoshi-1.0",
    "messages": [
      {"role": "user", "content": "Summarize this document into bullet points."}
    ]
  }'

Or use the OpenAI SDK:

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.shogo.ai/v1"
)

response = client.chat.completions.create(
    model="hoshi-1.0",
    messages=[{"role": "user", "content": "Summarize this document into bullet points."}]
)
print(response.choices[0].message.content)

Routing: Use Hoshi by Default, Frontier by Exception

Odin AI Platform’s model routing lets you set Hoshi 1.0 as your default model across all agents and selectively override to a frontier model only when a specific task demands it. This gives you the best of both worlds:

Default to Hoshi — all agents run on Hoshi 1.0 for cost-efficient, high-quality performance.
Override per agent — switch individual agents to Sonnet 5 or GPT 5.5 when the task requires it (e.g., multimodal analysis, ultra-long context).
Monitor and adjust — track performance and cost per agent, then optimize your model mix over time.

FAQ

Is Hoshi 1.0 as good as Sonnet 5 or GPT 5.5?

For agentic tasks — tool calling, structured output, coding, and multi-step reasoning — Hoshi 1.0 performs at the same frontier tier. Frontier models may have an edge on highly creative writing, multimodal reasoning, and extremely long contexts.

Can I use Hoshi 1.0 with my own API key?

Yes. Hoshi 1.0 is available both as a predefined model in Odin AI Platform (no key needed) and via the raw API with your own Shogo API key.

What is cached input pricing?

When you send the same context repeatedly (e.g., the same system prompt or knowledge base retrieval), cached tokens are billed at 10 credits / 1M — roughly 15× cheaper than fresh input tokens.

How does Hoshi handle data privacy?

Hoshi 1.0 runs on Shogo infrastructure. Your data is not used to train the model. For full details, see the Shogo privacy policy.

Will Hoshi 1.0 be deprecated soon?

No. Hoshi 1.0 is our flagship model and will be actively maintained and improved. Future versions will be announced with clear migration timelines.
