Monthly cost at list price for five common workloads. Token counts per unit are stated so you can scale them to your own traffic. A workload that does not fit a model's context window is marked rather than priced.
| Workload (per month) | Elorian: Glimpse | OpenAI: GPT-5.1-Codex | Difference |
|---|---|---|---|
| Customer-support chatbot 50,000 conversations — each a 6-turn conversation (1,500 in / 400 out tokens) | $105 | $294 | Elorian: Glimpse saves $189 |
| RAG search over documents 20,000 questions — each a question answered from ~8 retrieved passages (6,000 in / 500 out tokens) | $102 | $250 | Elorian: Glimpse saves $148 |
| Coding / tool-using agent 2,000 tasks — each a multi-step task with tool calls and file context (60,000 in / 6,000 out tokens) | $108 | $270 | Elorian: Glimpse saves $162 |
| Batch summarisation 10,000 documents — each a 6,000-word report summarised to a page (8,000 in / 600 out tokens) | $66.00 | $160 | Elorian: Glimpse saves $94.00 |
| Long-document analysis 500 documents — each a 150-page contract or codebase read in one pass (100,000 in / 2,000 out tokens) | $33.00 | $72.50 | Elorian: Glimpse saves $39.50 |
| Capability | Elorian: Glimpse | OpenAI: GPT-5.1-Codex | What it lets you do |
|---|---|---|---|
| Tool / function calling | ✓ Yes | ✓ Yes | call your APIs and run agent loops |
| Structured output (JSON schema) | ✓ Yes | ✓ Yes | return JSON that validates against your schema |
| Reasoning / thinking mode | ✓ Yes | ✓ Yes | spend extra tokens thinking before answering hard problems |
| Image input | ✓ Yes | ✓ Yes | read screenshots, charts and scanned pages |
| Audio input | — | — | take speech or audio directly |
| File / PDF input | — | — | accept documents without your own parsing step |

| Built-in web search | — | ✓ Yes | answer from live web results |
| Seed (reproducible sampling) | — | ✓ Yes | repeat a generation for tests and evals |
| Log-probabilities | ✓ Yes | — | read token confidence for classification and scoring |
From each model's published parameters and input/output types. “—” means not advertised, not proven absent.
Neither wins outright: Elorian: Glimpse is the pick when cost matters at scale, OpenAI: GPT-5.1-Codex when you need to fit long inputs in one request. In short: Elorian: Glimpse when cost matters at scale, you need log-probabilities, you generate long outputs in one go, you want the newer model; OpenAI: GPT-5.1-Codex when you need to fit long inputs in one request, you need built-in web search, you need seed (reproducible sampling).
Elorian: Glimpse is cheaper: $1.20 vs $3.44 per 1M tokens at a typical 3:1 input/output mix, 65% less. For 50,000 support conversations a month that is $105 against $294.
Elorian: Glimpse costs $0.60 per 1M input tokens and $3.00 per 1M output tokens; OpenAI: GPT-5.1-Codex costs $1.25 input and $10.00 output. Output tokens are billed separately, so long answers shift the gap.
OpenAI: GPT-5.1-Codex: 400K tokens, about 600 pages, against 262K (about 393 pages) for Elorian: Glimpse.
Tool calling — Elorian: Glimpse: yes, OpenAI: GPT-5.1-Codex: yes. JSON-schema structured output — Elorian: Glimpse: yes, OpenAI: GPT-5.1-Codex: yes.
Yes, both accept image input.
No free variant is listed for either; both are pay-per-token.
Elorian: Glimpse can write up to 256K tokens (about 192,000 words) per response; OpenAI: GPT-5.1-Codex up to 128K (about 96,000 words).
Elorian: Glimpse was listed on 2026-10-17; OpenAI: GPT-5.1-Codex on 2025-11-13.
